1 April 1845 → The first public telegraph line went into service. It was customary among the telegraph operators to advise each other of local weather conditions and even to predict the movement of weather changes.
1 April 1884 → Of the 30 houses in Oakville, IN, only 3 were left standing after an F5 (estimated) tornado leveled the town. Meteorologists at the time felt it was one of the most intense tornadoes ever recorded. Pieces of obliterated farms were found four miles away. Eight people were killed, mostly children.
1 April 1960 → TIROS I, the very first weather satellite, was launched from Cape Canaveral.
1960: The first weather satellite, TIROS 1 (Television and Infra Red Observation Satellite,) began sending pictures back to earth. The TIROS series would have little benefit to operational weather forecasters because the image quality was low and inconsistent. The most important understanding achieved from the new technology was the discovery of the high degree of organization of large-scale weather systems, a fact never apparent from ground and aircraft observations. 
1 April 1987 → A tornado touched down briefly during a snow squall on the south shore of White Fish Bay on Lake Superior. A mobile home had its roof ripped off and insulation sucked from the walls.
1 April 1987: Forty-five cities across the southeastern U.S. reported record low temperatures for the date. Lows of 37 degrees at Apalachicola, 34 degrees at Jacksonville Florida, 30 degrees at Macon Georgia, and 22 degrees at Knoxville Tennessee, were records for April.
1 April 1875: The first daily newspaper weather map was published by the London Times. The first American newspaper weather map would be published on 5/12/1876 in the New York Herald. Weather maps would first appear on a regular basis beginning on 5/9/1879 in the New York Daily Graphic.

2 April 1924 → A Weather Bureau scientist and assistant took a hot air balloon ride for the purpose of obtaining upper atmosphere measurements on the instruments they brought along. They lifted off from Scott Air Force Base near St. Louis and landed 700 miles downstream in South Carolina.
2 April 1957: An F3 tornado tore through Dallas, TX. 10 people were killed and 216 were injured. Total damage was $1.5 million dollars. This tornado was among the most photographed and studied in history. Click HERE for more information.  http://www.srh.noaa.gov/fwd/?n=dallastor50year
2 April 1982 → Severe thunderstorms touched off 56 tornadoes in the central U.S. An F5 multiple vortex tornado traveled 53 miles from Speer to Broken Bow in southeast Oklahoma. It was the first U.S. F5 tornado after a five year drought.  http://www.srh.noaa.gov/fwd/?n=paris1982
2 April 2002 → Tornado hit eastern India killing at least 9 people and flattening nearly 900 homes.
2 April 1936: An estimated F4 tornado cut a 15-mile path through Crisp County, GA. The hardest hit area was the town of Cordele, where 276 homes were destroyed in a five-block swath through the town. The storm was on a course that would have missed the center of town, but it made a left turn towards the end of its path. 23 people were killed and 500 injured. Total damage was $3 million dollars.

2 April 1982: Severe thunderstorms spawned fifty-six tornadoes in the central U.S., including seventeen in the Red River Region of Texas and Oklahoma. The tornadoes claimed thirty lives and injured 383 other persons. A violent tornado near Messer, Oklahoma left only the carpet tack strips on the slab of a house it destroyed, and carried a motel sign thirty miles.

3 April 1956 → An F5 tornado killed 18 people and destroyed 332 homes southwest and west of Grand Rapids, MI. Businesses were swept completely away in Hudsonville and Standale.   http://www.crh.noaa.gov/grr/science/19560403/
3 April 1964 → An F5 tornado ripped into Wichita Falls, TX and Sheppard Air Force Base. At least 225 homes were destroyed in town, and the base suffered $2.8 million damage as planes, a hangar, the power plant, and the chapel were destroyed. It was the first time a tornado was broadcast live on TV by a local news station.
3 April 1974 → One of the largest tornado outbreaks ever recorded took place, with at least 148 tornadoes occurring from Illinois east to Ontario and south to Alabama. Monticello, IN; Xenia, OH; and Guin, AL were especially hard hit.   http://www.publicaffairs.noaa.gov/storms/

3 April 1974: A "Super-Outbreak" of tornadoes ravaged the Midwest and the eastern U.S. Severe weather erupted early in the afternoon and continued through the next day. Severe thunderstorms spawned 148 tornadoes from Alabama to Michigan, most of which occurred between 1 PM (CST) on the 3rd and 1 AM on the 4th. The tornadoes killed 315 persons, injured 5300 others, and caused 600 million dollars damage. Alabama, Kentucky and Ohio were especially hard hit in the tornado outbreak. One tornado destroyed half of the town of Xenia, Ohio killing 34 persons. Another tornado, near the town of Stamping Ground, Kentucky produced a path of destruction a record five miles in width. A tornado raced through Guin, Alabama at a speed of 75 mph. Two powerful tornadoes roared across northern Alabama during the early evening hours, killing fifty persons and injuring 500 others. Some rescue vehicles responding to the first tornado were struck by the second.
3 April 1987 →A large, slow moving low pressure system produced very heavy snows over the Appalachian Region lasting through April 5th. 60 inches fell at Newfound Gap in western North Carolina, the largest single storm snowfall in the state's history. Up to 36 inches was reported in southeastern Kentucky. The total of 25 inches at Charleston, WV easily surpassed its previous record for the entire month of April of 5.9 inches. The 20.6 inch total at Akron, OH established an all-time record for that location. Interstate 40 was closed by snow for the first time since it was opened in 1967. Lightning and thunder accompanied the snow in some areas while a trace fell as far south as Mobile. This was the first snow ever reported in the month of April in Mobile since records began in 1872. The storm became known unofficially as the "Dogwood Snowstorm" as many trees had fully bloomed.
3 April 1898: An avalanche near Chilkoot Pass, Alaska in the Yukon during the Gold Rush buried 142 people and killed 43 others. Click HERE for more information from the Library and Archives of Canada.

4 April 1804 → A family of tornadoes killed 11 people along a 120 mile long path from Bibb County, GA to Edgefield County, SC. Some buildings were completely swept away. Effects of the tornadoes were still visible when another powerful tornado family followed a similar path in 1875.
4 April 1893 → The first week of April back in 1893, was one of the warmest weeks ever during April at Oklahoma City, Oklahoma. From the 3rd through the 7th, the high temperature averaged an incredible 94 degrees. In fact, each of the daily high temperatures over that five-day period remains a record more than 100 years later. Despite the week of heat, April 1893 does not rank as one of the top ten warmest Aprils on record in Oklahoma City.   
4 April 1929 → Northern Tasmania Flood. The most disastrous floods experienced in the 20th Century in Tasmania. Twenty-two people drowned, the greatest loss of life for any single Australian flood event. Fourteen people died when the Briseis Dam at Derby burst, and a further eight lives were lost near Ulverstone when a vehicle plunged into the flooded river. Many road and rail bridges were destroyed.
4 April 1966 →  One of the strongest tornadoes in Florida's history moved in from the Gulf of Mexico and ripped through Pinellas, Hillsborough, Polk, and Osceola Counties. Damage was very severe in the towns of Gibsonia and Galloway in Polk County. 11 people were killed and 350 were injured. The tornado was classified as F4. 
4 April 1977 → An F5 tornado swept homes away north of Birmingham, AL. It moved forward at 60 mph, doing $15 million damage. Cars and trucks were thrown from I-65 as the tornado crossed the highway.  http://www.srh.noaa.gov/bmx/?n=event_04041977
1977: A massive F5 tornado moved across northern Birmingham, Alabama, killing 22 people and injuring 130. The tornado cut a 15-mile path from just northwest of Birmingham to the town of Tarrant. 167 homes were destroyed, primarily in the Smithfield Estates subdivision. Daniel Payne College sustained heavy damage. At one point, the tornado was three-quarters of a mile wide. The tornado crossed busy I-65, tossing cars and trucks like they were toys. Other tornadoes killed 1 other person in Alabama and 1 person in Georgia that day.
4 April 1977 → Southern Airways Flight 242 flew directly into a severe thunderstorm. The plane was so badly beaten by hail and rain that both of its engines were destroyed. The craft fell 14,000 feet, landing on a highway in New Hope, GA. Of the 81 people on board, 63 were killed. Nine people on the ground lost their lives as the plane skidded into a gas station and grocery store.
4 April 1804: A group of tornadoes slashed a 120-mile path across seven counties in Georgia and one county in South Carolina killing 11 people near Augusta, GA. The tornado's path through heavy timber was still visible some 71 years later as noted in an Army Signal Corps survey.

IVb. The Deadliest and Most Intense Anticyclonic Tornado Ever Recorded

In April of 1981, a thunderstorm developed over Washington County, Wisconsin. The storm resembled a typical nighttime thunderstorm on weather radar, so no tornado watch was issued. Despite the storm’s modest size and low cloud tops, it spawned an unusual anticyclonic tornado just after midnight. The short-lived tornado touched down at the edge of a neighborhood in the town of West Bend (visible above) and immediately began causing F4 damage (Wakimoto, 1983). Several two-story houses were leveled to the ground and three people were killed, including one man who was thrown more than 50 yards from his destroyed home. The rapidly intensifying tornado was exceptionally narrow, often less than 50 yards in width, and dissipated after traveling less than two miles. The event remains a meteorological oddity and the only violent anticyclonic tornado ever recorded. (Images by Patrick Golembiewski)

5 April 1815 →  The Tambora Volcano in Java erupted. Ash from the eruption would circle the globe, blocking sunlight and leading to the unusually cold summer in 1816. On 6/6/1816, snow would fall as far south of Connecticut with some places in New England picking up 10 inches. On July 4th, the temperature at Savannah GA plunged to 46 degrees. Eastern North America and Europe had freezing nighttime temperatures in August.  
5 April 1936 →  446 people were killed in the second deadliest tornado outbreak ever in U.S. 17 twisters struck from Mississippi to the Carolinas. An F5 tornado cut a path 400 yards wide through the residential section of Tupelo, MS. 216 people were killed and 700 were injured. The tornado had a 15 mile long path and did $3 million dollars in damage. One of the survivors in Tupelo was a baby of an economically strapped family who had an infant they'd recently named ELVIS AARON PRESLEY. Luckily, Elvis had left the building. Gainesville, GA had 203 fatalities and 934 injuries from a tornado that occurred early the following morning. 
5 April 1972 → Washington's deadliest tornado, an F2, moved from the north side of Portland, OR to the east side of Vancouver, WA. Two mothers and three children were killed when a store wall collapsed, and a sixth victim was killed in a bowling alley across the street. About 150 students were hurt by flying glass at Ogden Elementary School.
1972: A tornado, 500 yards wide at times, touched down at a marina on the Oregon side of the Columbia River, and then tore through Vancouver WA. The tornado killed six persons, injuring 300 others, and causing more than five million dollars damage. It was the deadliest tornado of the year and the worst of record for Washington.
5 April 1977 → Flood peaks during April 4-5, 1977, along the Tug Fork and Guyandotte Rivers in West Virginia exceeded all known discharges. Communities along the Tug Fork from Welch to Fort Gay were inundated by 20-25 feet of water. The small communities of Matewan, Thacker, and Lobata were completely inundated. On the Tug Fork near Litwar, the peak stage exceeded the previous highest stage by about 6 feet. A floodwall that protects Williamson to a stage of about 44 feet was overtopped by more than 8 feet.
5 April 1982 → An unprecedented April blizzard blanketed much of the central and southern Appalachians. Mt. Mitchell, NC received 35 inches of snow, and up to five feet of snow was reported in the mountains along the North Carolina-Tennessee border.
5 April 1997 → A severe ice and snow storm affected eastern North Dakota with winds up to 65 mph and visibility near zero. The weight of ice downed many power lines and caused a 2000 ft TV tower to collapse.
5 April 1815: The Tambora Volcano in Java began erupting on this day. A few days later on the 10th, Tambora produced the largest eruption known on the planet in the last 10,000 years. Ash from the eruption would circle the globe, blocking sunlight and leading to the unusually cold summer in 1816. On 6/6/1816, snow would fall as far south of Connecticut with some places in New England picking up 10 inches. On July 4th, 1816, the temperature at Savannah GA plunged to 46 degrees. Eastern North America and Europe had freezing nighttime temperatures in August. Click HERE for more information from Volcano Discovery.com
5 April 1936: Approximately 454 people were killed in the second-deadliest tornado outbreak ever in U.S. More than 12 twisters struck Arkansas to South Carolina. An estimated F5 tornado cut a path 400 yards wide through the residential section of Tupelo, Mississippi. At least 216 people were killed and 700 were injured. The tornado had a 15-mile long path and did $3 million dollars in damage. One of the survivors in Tupelo was a baby of an economically strapped family who had an infant they'd recently named Elvis Aaron Presley. Gainesville, Georgia had at least 203 fatalities and 934 injuries from an estimated F4 tornado that occurred early the following morning.

6 April 1926 → A few minutes after midnight a tornado came ashore from the Pacific at National City, CA, resulting in the most damaging tornado on record in San Diego County. 8 people were injured. Two homes were totally destroyed. One shingle was driven into the side of a building as if it had been shot from a gun. Trees were downed and power was knocked out.
6 April 1936 → A tornado outbreak in the Deep South resulted in a total of 446 deaths and $128 million in damage. During the evening of the 5th, a tornado hit Tupelo, MS, killing 216 persons and damaging infant Elvis Presley's neighborhood. The next morning, the paths of two tornadoes met at 8:30 AM and cut a swath four blocks wide through Gainesville, GA, killing 203 persons. At least 70 people died in the Cooper Pants Factory, possibly the greatest tornado toll ever for a single building.
6 April 1973 →On this date through the 8th, a major spring snowstorm dumped 11.6 inches of snow across Denver, Colorado. Most of the heavy wet snow of 10.1 inches fell on the 7th when temperatures remained in the 20s. The low temperature of 5 degrees on the 8th was a new record low for the date and the lowest for so late in the season.  
6 April 2007 →In Cleveland, Ohio on the 6th to the 9th: 
The opening-season series between the Indians and Minnesota Twins is wiped out by a snowstorm and a cold snap. The Indians lead 4-0 when their home opener Friday on the 6th was called off by umpires because of heavy snow. The grounds crew who tried to make the field playable with backpack blowers and brooms, spent more time on the field than the players during nearly three hours of stoppages. About a foot of snow remained on the field Monday afternoon the 9th.
6 April 1909: American explorer Robert Peary and five others reached what they determined to be the North Pole on this day. Historical analysis suggests he fell a few miles short of reaching his goal. Click HERE for more information from the History Channel.

7 April 1926 →  Lightning started a disastrous oil fire at San Luis Obispo, California which lasted for five days, spreading over 900 acres, and burned nearly six million barrels of oil. Flames reached 1000 feet and the fire temperature was estimated at 2,500 degrees. The fire spawned thousands of whirlwinds with hundreds the size of small tornadoes. One vortex traveled one mile to the east-northeast of the blaze, destroying a small farm house and killing two people. Damage totaled $15 million dollars.  
7 April 1987 → International Falls, MN, with a record warm afternoon high of 71 degrees, was warmer than Miami, where the high was a record cool 66 degrees.

7 April 1948: Six tornadoes ripped through Northern Illinois and Indiana; mainly across the southern and eastern suburbs of Chicago. The hardest hit was from a tornado that moved east from near Manteno, IL to near Hebron, IN. This storm left four people dead; three in Grant Park, IL and one near Hebron, IN with 67 injuries and over a million dollars damage. Other strong tornadoes in the area moved from near Coal City, IL to Braidwood, IL and from Calumet City, IL into Indiana. Further south, two strong tornadoes occurred across the northern parts of Champaign and Vermilion Counties in Illinois.
7 April 1980: Severe thunderstorms spawned tornadoes that ripped through central Arkansas. The severe thunderstorms also produce high winds and baseball size hail. Five counties were declared disaster areas by President Carter. A tornado causing F3 damage also affected St. Louis and St. Charles counties in Missouri producing $2.5 million dollars in damage.

8 April 1938: Snow began to fall over central Oklahoma during the previous evening and continued to this day. In Oklahoma City, several snowfall records for the month soon fell to the storm, including the record for most total snowfall during the month of April. The Oklahoma City snowfall totals of 0.8 inches on the 7th and 3.3 inches on the 8th remain daily records. In fact, the 3.3 inches of snow on the 8th is the most ever to fall on any single April day. The 4.1 inch total for the month continues as the greatest April monthly snowfall total.
8 April 1973: The state of Iowa and southwest Wisconsin saw severe blizzard conditions from April 8 through the 10th. Sustained wind of 40 to 50 mph, with gusts to 65 mph was reported with falling snow. Highways were closed, travel was suspended, and properties were damaged.

http://www.weather.gov/lot/Palm_Sunday_Outbreak ** 
1965: Severe thunderstorms in the Upper Midwest spawned fifty-one tornadoes killing 256 persons and causing more than 200 million dollars damage. Indiana, Ohio and Michigan were hardest hit in the "Palm Sunday Tornado Outbreak". Although no F5s were officially reported, at least 22 were rated as F3 or F4. This is the third deadliest day for tornadoes on record, behind the Super Outbreak of 4/3/1974, and the outbreak that included the Tri-State Tornado of 3/18/1925. Dr. Ted Fujita discovered suction vortices during the Palm Sunday tornado outbreak. It had been believed the reason why tornadoes could hit one house and leave another across the street completely unscathed was because the whole tornado would "jump" from one house to another. However, the actual reason is because most of the destruction is caused by suction vortices: small, intense mini-tornadoes within the main tornado.   
11 April 1987 → After 10 days of constant flooding in the northeastern part of the United States, the rain finally stopped. The damage from the rain and the melting snow counted into the billions. In New York, the State Thruway Bridge collapsed because of the flooding and claimed ten lives.
11 April 1991 → The world record was set for the longest distance a piece of tornado debris has been carried. A personal check was blown from a home in Stockton, KS by an F3 tornado and was found in Winnetoon, NE 223 miles away.

11 April 1989 → 1989: Forty-four cities in the south central and eastern U.S. reported new record low temperatures for the date. Lows of 25 degrees at Conway Arkansas, 29 degrees at Dallas/Fort Worth Texas, and 22 degrees at Ozark Arkansas, were April records. Lows of 26 degrees at Hot Springs Arkansas and 31 degrees at Shreveport Louisiana equaled April records.

Over the next few hours, fast-moving hailstones pummeled the area north of Amarillo, Tex., which had lately been sitting in dust due to a lack of precipitation, according to the news organization. The hail mixed with melting hail turning the dust to mud and the mix create four-foot high mounds that shut down a major highway for the next 18 hours.

13 April 1921 → Melissa, TX was hit squarely by an F4 tornado that destroyed the town's business section along with 40 homes and all of the village's churches. In the town's school 240 children were huddled under their desks on the first floor while part of the second floor was ripped apart. The teacher was bruised as she struggled to hold a door shut, but no lives were lost in the school. Eleven people were killed elsewhere, a toll that would have been higher except that the roar of the tornado was so loud that people heard it and took shelter.
13 April 1984 → Between 11-14 April 1984, in St Johns, Newfoundland, ice accumulated up to 6 inches thick on power lines. Power outages left 200,000 residents of Avalon Peninsula in the dark and cold.

Hail grew up to about golf ball size and winds peaked at approximately 80 mph. The wind-driven hail broke windows in houses and blasted paint off the wooden siding. The strong winds took roofs off several mobile homes and at least one single-family house. Utility crews stated that a total of 27 poles were downed by the winds. The American Red Cross determined that 324 units were affected with 18 mobile homes and 4 houses destroyed. About 50-60 families were at least temporarily displaced.

23 April 1792 → John Thomas Romney Robinson, inventor of the cup anemometer, was born.
23 April 1908 → An extensive tornado outbreak began around noon today in Minnesota, and wouldn't end until the evening of the 25th in Georgia. The strongest tornado of the event was an F5 (estimated) near Pender, NE today where a farm was swept away and debris was found 35 miles distant.
23 April 1910 → The temperature at the Civic Center in Los Angeles hit 100 degrees to establish an April record for the city.
23 April 1988 → In southern California, a winter-like storm brought thunderstorms. Nine girls in Tustin were injured when lightning struck the tree they were standing under to shield themselves from the rain.
23 April 1961: Severe weather struck the south suburbs of Chicago, IL. Joliet, IL reported an inch of hail with some hailstones the size of golf balls. Heavy rain from these storms also resulted in some flooding. A tornado struck the town of Peotone resulting in damage to nearly every building with damage also reported in Lorenzo and Wilton Center, IL. Damage was estimated at $9 million dollars with about 30,000 structures affected. 
23 April 1989: Salina Kansas was the hot spot in the nation with a high of 105 degrees. The high of 105 degrees established an April record for the state of Kansas.
23 April 1999: On Friday, April 23, 1999 a horrific hailstorm moved southeast from Pennsylvania across Garrett County, Maryland and into the Eastern Panhandle of West Virginia. It had weakened some as it crossed Garrett County and the Allegany Front, but as it passed east of Keyser, West Virginia, hail began to increase in size once again. By the time it reached Capon Bridge in eastern Hampshire County, West Virginia, the size of the hail had grown from golf balls to baseballs. As it moved into Frederick County, VA, the hail storm continued to grow dropping golf ball size hail in a swath now reaching from the north of Winchester, south to Stephen City (about 10 miles). The intensity of the hail stripped and shredded leaves and bark from the newly budding trees. Hailstones grew to the size of Grapefruit (4 inches in diameter) just east of Winchester. The storm continued east through Clarke County, southern Loudoun and northern Fauquier doing considerable damage to Middleburg, then across Fairfax County hitting Centreville, Chantilly, Fairfax, Burke, Springfield, and Lorton with golf ball to baseball size hail. It crossed the Potomac River and weakened just slightly. It moved across northern Charles, clipped southern Prince Georges and then into Calvert County with 1 inch to 1.5-inch diameter hail and onto the Chesapeake Bay continuing southeast to the ocean. The damage left behind was incredible. In Northern Virginia alone, it amounted to over $50 million dollars in losses to public and private properties. Some communities saw a third of the homes with siding and roof damage. Some required total replacement. Windows were broken, cars dented and windshields smashed. Piles of shredded plant debris were left on the ground in the storm path. In about 6 hours of time, this one thunderstorm, moving at about 50 mph, did $75 million in damage. There have been other bad hailstorms to hit this area before, but none to cause this much damage to property.
23 April 1948: A three-block long section was devastated at the edge of Ionia, Iowa in Chickasaw County by an estimated F4 tornado. Six homes and a church were leveled, and nine other homes were severely damaged. Two deaths occurred in the collapse of the Huffman Implement Store. Overall, the tornado killed five people, injured 25, and caused $250,000 in damages. An F2 tornado touched down initially 5 miles northeast of Rochester. Barns, silos, windmills, and machinery were destroyed on four farms as this tornado tracked north.

In Maryland, three deaths and 122 injuries were a direct result of the storm. Property damage exceeded $100 million. Tornadoes along the Atlantic coast are not common, and tornadoes of this magnitude are extremely rare. Only six F4 tornadoes have occurred farther north and east of the La Plata storm: Worchester, Massachusetts - 1953; New York/Massachusetts - 1973; Windsor Locks, Connecticut - 1979; five counties in New York - 1989; New Haven, Connecticut - 1989; North Egremont, Massachusetts - 1995. None was as close to the coast. The tornado traveled across the Chesapeake Bay almost to the Atlantic. Click HERE for more information from the NWS Service Assessment.

MQT Today in History http://www.weather.gov/mqt/today_in_history
This "Day in Weather History" contains memorable weather events for much of Michigan's Upper Peninsula. Many sources were used to research and compile the data.
April 1

1987: On April 1, 1987, an F0 tornado touched down briefly in the early afternoon during a snow squall on the south shore of Whitefish Bay on Lake Superior about 5 miles NNW of Brimley, MI. A mobile home had its roof ripped off and insulation sucked from the walls. The tornado was on the ground for 0.10 mile and the damage width was 10 yards and it caused $2500 worth of property damage.

2010: On April 1, 2010, after a record warmest March, record heat continues at NWS Marquette with a daily record high temperature of 68F.

1960: On April 1, 1960, TIROS-1 (Television Infrared Observation Satellite) was the first weather satellite. This satellite lasted only 78 days in a polar orbit. The first image from it was a fuzzy picture of thick bands and clusters of clouds over the United States.

1920: On April 1, 1920, 5 days after a flood began in Manistique, water was still sweeping into the west side of Manistique. 70 families were rendered homeless. The Paper mill was flooded on the first floor with 2 feet of water. The raging flood in Manistique washed out foundations and sent 125,000 feet of lumber into Lake Michigan which wiped out the Goodwillie Brothers box factory.

1963: On April 1, 1963, Ontonagon had a high temperature of 70F. The first heavy ice flow came down the Ontonagon River and jammed up against the railroad bridge causing flooding over the island between the river and slough and throughout the center of Ontonagon spreading icy water from 2-3 feet deep. Ontonagon had boat houses demolished along with boats due to flooding and boats were swept out into Lake Superior or wrecked by the ice. Damage to the city was estimated at over a half million dollars in 1963.

2008: On April 1, 2008, a low pressure system originating over the Plains deepened as it moved into the Western Great Lakes on March 31st. Snow mixed with rain and sleet over the east and south central counties of Upper Michigan on the afternoon of the 31st and then fell heavy at times through the evening of March 31st into April 1st. The combination of heavy snow and north winds gusting as high as 50 mph near the Lake Superior shore led to blizzard conditions as well as numerous power outages over Marquette and Alger counties. WFO Marquette recorded record daily snowfall of 15.8 inches and record daily water equivalent of 1.83 inches. Observers at Rainbow Lodge and Newberry measured eight inches of snow in 12 hours. Storm total snowfall amounts of six to nine inches were reported across Keweenaw County ending on the morning of the 1st. North winds gusting over 30 mph at times also caused considerable blowing and drifting of snow.

April 2
2010: On April 2, 2010, after a record warmest March, record heat continues at NWS Marquette with a daily record high temperature of 75F.
2005: On April 2, 2005, in the morning, an ice jam 200 to 300 feet in length formed on the Rapid River three miles north of Rapid River, MI. Minor flooding occurred in the Rapid River and Maplewood areas with water flowing over Highway US-2 in Rapid River. Around noon on the 3rd, an excavator was used to break up the ice jam, and within a few hours, flood waters had receded. 
April 3
1963: On April 3, 1963, the city of Marquette had a record high temperature of 72F and WFO Marquette had a record high temperature of 65F.
1894: On April 3, 1894, the wood freighter William H. Barnum, while hauling 55,000 bushels of corn, had her hull cut by floating ice and she attempted to make it to shore, but came up against shelf ice and stranded. The wrecking tug Crusader tried to save her, but was only able to take her crew off before she went down in 11 fathoms of water 5.5 miles ese of Mackinaw City in Lake Huron. She was reportedly in poor condition at the time of her last trip and had been given insurance for only that single voyage. She had been bound Chicago for Port Huron and was one of the first vessels to attempt the Straits of Mackinac that spring. 
April 4
2002: On April 4, 2002, a 3-4 foot deep snowpack remained over much of central and western Upper Michigan with 9-10 inches of water in it. This led to snowmelt flooding in mid April across western and central Upper Michigan.
1894: On April 4, 1894, the wood freighter Minneapolis, while carrying 48,517 bushels of wheat, was damaged by ice and then ran across a rocky bottom near McGulpin Point, causing her to leak profusely. She sank quickly almost under the current site of the Mackinac Bridge in the Straits of Mackinac in Lake Michigan after her fires were put out by the rising water. Her crew was rescued by the schooner San Diego, part of her tow. One crew-member claimed that she was holed by ice where her iron plating had been removed to repair the wooden hull and was not replaced.
2007: On April 4, 2007, an intense storm system tracking from the Plains into the Great Lakes dumped heavy lake enhanced snow across much of Upper Michigan from the 3rd into the 7th. Blizzard to near-blizzard conditions also occurred from the 4th continuing into the 5th closing many schools and businesses throughout the area. Wind gusts estimated in excess of 50 mph caused damage at a home in Breitung Township just north of Iron Mountain on the 4th. A large pine tree toppled and damaged a backyard deck, an air conditioning unit, a rabbit pen and caused a leak in the natural gas line.
1999: On April 4, 1999, a low pressure center from northern Minnesota moved east to northern Lake Michigan with a stationary front remaining just south of Upper Michigan. Warmer air aloft and freezing temperatures at the surface combined to produce a period of freezing rain across north central Upper Michigan. Ice accumulations of around half an inch thick were reported by NWS electronic technicians working on equipment in Houghton and Copper Harbor. Local power companies reported outages due to tree branches breaking and falling across power lines. Police departments reported numerous minor traffic accidents due to slick roads.
April 5
1979: On April 5, 1979, snowfall rates up to 3 inches an hour were reached during the evening at Sault Ste Marie in a blinding snowstorm.
2003: On April 5, 2003, a low pressure system followed the stalled frontal boundary east across the southern Great Lakes and brought another round of snow to Upper Michigan late on April 4th into the 5th. This time, the heaviest snow fell over south central and eastern Upper Michigan. Eight to twelve inches of new snow accumulated in a strip from Norway and Menominee through Escanaba to Seney and Newberry before snow diminished during the morning on April 5th. Snowfall decreased sharply to the northwest of this band, and snowfall amounts of 3 inches or less were reported over northwest Upper Michigan. On the morning of the 5th, snowfall reports included 8 inches in Iron River, Iron Mountain, Munising and Seney, 9 inches in Gulliver, and Carlshend, and 10 inches in Menominee, Escanaba and Newberry. Rapid River measured 12 inches.
2007: On April 5, 2007, an intense storm system tracking from the Plains into the Great Lakes dumped heavy lake enhanced snow across much of Upper Michigan from the 3rd into the 7th. Blizzard to near-blizzard conditions also occurred from the 4th continuing into the 5th closing many schools and businesses throughout the area. An observer at Ironwood measured 24 inches of snow from the 3rd into the morning of the 5th. There was a break in snowfall through much of the 5th into the afternoon of the 6th. More snow then fell late on the 6th into midday on the 7th with an additional 5 inches at Ironwood and 8 to 10 inches at Wakefield. North winds gusted over 30 mph at times on the 4th and caused considerable blowing and drifting of snow and hazardous travel conditions. Some schools closed on the 4th...including Gogebic Community College. A few minor accidents were reported due to the snow and ice-packed roads.
April 6
1979: On April 6, 1979, wind gusts to 60 mph during the morning at Sault Ste Marie in heavy snow with whiteouts and power outages were reported. Trees were blown down on houses, cars and garages. A state of emergency was declared for Sault Ste Marie and Chippewa County due to the snowstorm with a power outage causing the pumping station to quit working causing much of the water to be shut off to the city until noon on the 7th. It was the first time in 35 years that mail service was cancelled in Sault Ste Marie due to the snowstorm. At Bay Mills, a 30 foot wall of ice came onshore during the snowstorm. The city of Marquette recorded a low temperature of 8F this morning following the snowstorm to hit the eastern U.P.
1898: On April 6, 1898, the wood schooner, 4-mast Northwest, while carrying corn, was in tow of steamer Aurora, when she struck a submerged ice floe and sank in Big Stone Bay in the Straits of Mackinac in Lake Michigan. Aurora picked up the survivors.
April 7
1857: On April 7, 1857, the low temperature fell to -16F at Norwich Mine near Ontonagon.

2007: On April 7, 2007, an intense storm system tracking from the Plains into the Great Lakes dumped heavy lake enhanced snow across much of Upper Michigan from the 3rd into the 7th. Blizzard to near-blizzard conditions also occurred from the 4th continuing into the 5th closing many schools and businesses throughout the area. Heavy snow continued at times from late on the 5th through the morning of the 7th. Northwest winds gusting to 30 mph or greater caused reduced visibilities of one-half mile or less in snow and blowing snow. Storm total snowfall accumulations included 38 inches south of Grand Marais, 33 inches at Munising and south of Wetmore and 24 inches at Shingleton and local accumulations reached 18 inches near Paradise. An observer at Watton measured 10.4 inches of snow in the 24 hour period ending on the 4th. There were several minor accidents on the 4th due to the heavy snow. There was generally a break in heavy snow from the 5th into the morning of the 6th before another 12 inches of snow fell at Herman during the afternoon of the 6th into the morning of the 7th. Storm total snowfall ending on the morning of the 7th included 35 inches at Herman...21 inches at Watton and 16 inches at Baraga. Blizzard to near-blizzard conditions also occurred from the 4th continuing into the 5th closing many schools and businesses throughout the area of Delta and Northern Schoolcraft Counties. Periods of heavy snow continued from the 5th into the 7th. The combination of heavy snow and north winds gusting to 30 mph or greater reduced visibility to one-half mile or less at times in snow and blowing snow. Storm total accumulations ending on the 7th...included over 60 inches at Painesdale, 38 inches at Atlantic Mine, 33 inches at Laurium and 31 inches at Houghton. Storm total snowfall accumulations included 48 inches at NWS Marquette...27 inches at Green Garden...25 inches at Champion and 20 inches in downtown Marquette. The calendar day snowfall total of 24 inches at NWS Marquette on the 4th was the second highest total ever for any calendar day at the station. A spotter along Highway M-77 near the Alger County border observed 33 inches of storm total snowfall ending on the 7th. Northwest winds gusting to 30 mph or greater at times also caused occasional whiteout conditions in heavy snow and blowing snow. 
April 8
1871: On April 8, 1871, the wood schooner, 2-mast Thomas Kingsford, while carrying corn, was cut by an ice floe and sank on Waugoschance Reef in the Straits of Mackinac in Lake Michigan, only 25 feet from the lighthouse pier. She resisted efforts by the big wrecker Leviathan to pull her off and later was washed off by a storm, at which point she went to pieces. Much of her gear was later salvaged by Chicago wrecker Capt. Michael Beffel or Beffels in the sloop D. M. Norton.
2010: On April 8, 2010, a low pressure system moving from the Plains into Lower Michigan produced moderate to heavy snow over portions of central Upper Michigan from late evening on the 7th through the 8th. WFO Marquette had a daily record snowfall of 9.8 inches. The heavy snow also contributed to hazardous driving conditions and poor visibility at times in Alger and Marquette Counties. The observer in Munising measured 6.5 inches of wet snow in less than 24 hours. A small portion of Chippewa County, near and north of a line from Pickford to Paradise, saw 5 to 7 inches of snow. Sault Ste Marie picked up 7.2 inches. Observers throughout much of Delta County measured a widespread four to seven inches of wet heavy snow in less than 24 hours. The observer near Norway measured four inches of wet snow in 12 hours. A widespread three to five inches of wet snow was reported across Menominee County from the evening of the 7th into the morning of the 8th.
April 9
1909: On April 9, 1909, the wood, bulk freight Eber Ward, while carrying corn, struck a growler or a floating ice cake and sank in less than 10 minutes just west of the south pier of Mackinac Bridge in the Straits of Mackinac in Lake Michigan. The survivors were picked up by the steamer Bennington. 5 crew members of 16 perished.
1979: On April 9, 1979, 7.8 inches of snow fell in Delaware, MI which brought the seasonal snowfall up to a record of 390.4 inches, the heaviest ever recorded in the U.P.
2008: On April 9, 2008, another low pressure system developing in the Plains tracked northeast toward the Upper Midwest and dropped heavy snow over portions of south central Upper Michigan on the evening of the 9th continuing into the morning of the 10th. Six inches of snow fell in a 12-hour period at Rock. An observer in Hermansville reported five inches of snow in 12 hours. Observers in Hardwood and Norway measured seven inches of heavy snow in 12 hours while eight inches accumulated in Iron Mountain. The snow forced the cancellation of schools in the Norway and Iron Mountain districts as well as North Dickinson and Pine Mountain Christian in Breitung Township. 
April 10
1850: On April 10, 1850, the wood schooner, 2-mast George Lawrence, while carrying 11,000 bushels of wheat, was bound Milwaukee for Buffalo, when she was cut by ice and sank in 48 feet of water in the Straits of Mackinac, 1 mile west of St. Helena Island in Lake Michigan. Out of Milwaukee, she was a loss of $17,500.
1933: On April 10, 1933, a wood U. S. Coast Guard motor rescue boat was on a rescue mission, when this small rescue craft was caught in the ice and crushed, a total loss in Whitefish Bay in Lake Superior.
April 11
2002: On April 11, 2002, 1.5 inches of rain fell on the Montreal River watershed which led to some flooding with flooded basements in Ironwood and plugged ditches causing road flooding around Bessemer.
2008: On April 11, 2008, a winter storm developed over the Plains and tracked northeast into the Upper Great Lakes. The storm dropped widespread heavy snow across Upper Michigan from the evening of the 10th into the afternoon of the 12th. Blizzard conditions also occurred over the Keweenaw Peninsula on the morning of the 11th. WFO Marquette had a daily snowfall record of 13.6 inches and record water equivalent of 2.22 inches. The observer ten miles south of Grand Marais measured eight inches in 12 hours. The observer at Bergland reported eight inches of snow in 12 hours. The observer 11 miles south of Kenton reported six to seven inches of snow along with wind gusts over 25 mph at times. The National Weather Service Office in Negaunee Township reported a storm total snowfall of 17.5 inches ending on the morning of the 12th. Water equivalent precipitation from the storm measured 2.90 inches. 
April 12
1996: On April 12, 1996, thunderstorms with rain and sleet broke out over the southern U.P. with 4.2 inches of snow falling at WFO Marquette.
2002: On April 12, 2002, rain continued into the morning with more than 2 inches falling on the thick snowpack and swollen rivers in the western U.P. in a span of 48 hours. The rain combined with 4 inches of snowmelt caused basements to flood in Ironwood and water collected in the low spots.
2008: On April 12, 2008, a winter storm developed over the Plains and tracked northeast into the Upper Great Lakes. The storm dropped widespread heavy snow across Upper Michigan from the evening of the 10th into the afternoon of the 12th. Blizzard conditions also occurred over the Keweenaw Peninsula on the morning of the 11th. An observer in Bark River near the Delta/Menominee County line measured nine inches of snow in 24 hours. Gladstone in Delta County recorded a total of 2.25 inches of water equivalent precipitation during the event from early on the 11th through the morning of the 12th. An observer in Iron Mountain measured five inches of snow in 12 hours. The National Weather Service in Negaunee Township reported a storm total snowfall of 17.5 inches ending on the morning of the 12th. Water equivalent precipitation from the storm measured 2.90 inches including a daily record of 2.22 inches on the 11th. Northeast winds also gusted over 30 mph at times during the event. 
April 13
1996: On April 13, 1996, heavy wet snow of 8.2 inches fell which was a daily record snowfall at WFO Marquette with a storm total of 12.4 inches from the 12-13th. The heaviest snow totals were over Marquette and Baraga Counties where northeast winds blowing off of Lake Superior boosted snow totals to 12 inches at Marquette and Herman, 10 inches at L'anse and 9 inches at Watton. Other snow totals included 8 inches at Au Train and Newberry, 7 inches at Pelkie, Munising, Channing and Michigamme and 6 inches at Watersmeet, Rockland and Ironwood. Areas south of Iron River and Newberry received mostly sleet and freezing rain.

April 15
2002: On April 15, 2002, a record high temperature 76F occurred at WFO Marquette.
See entry for day in http://www.weather.gov/mpx/wxhistory
1909: On April 15, 1909, the wood steam tug Fred B. Hall was damaged by ice and sank near Susie Island, MN in Lake Superior.
April 16
2002: On April 16, 2002, a record high temperature of 83F occurred at WFO Marquette. The low temperature was only 61F, the warmest low temperature ever for that early in the year. A warm airmass invaded the U.P. with low temperatures never falling below 60 degrees in many places and highs going above 80F which caused a massive meltdown of snow and led to record flooding. The Montreal River flooded 250 to 300 feet from the riverbank into Ironwood and rose across U.S. 2, making it impossible to cross into Hurley, WI. The highway was also flooded in Wakefield, effectively creating an island for about a week. Wakefield was inundated with Sunday Lake flooding causing school to be evacuated and causing homes to be flooded.
1980: On April 16, 1980, a record low temperature of 7F occurred at WFO Marquette.
2001: On April 16, 2001, low pressure moved south from Canada across the Great Lakes region. Unseasonably cold air wrapped into this system from the north, creating an area of heavy snowfall across eastern Upper Michigan. The snowfall began early in the morning and continued into the evening hours. By 8 pm, 12 hour snowfall totals of 8 to 11 inches were common across eastern Chippewa county.
1994: On April 16, 1994, snow of 6 to 10 inches fell over extreme western upper Michigan. Heaviest snow of 10 inches fell over Gogebic County. Northwest winds of 20 to 30 mph with gusts of 40 to 50 mph caused considerable blowing and drifting of snow.
2011: On April 16, 2011, a low pressure system lifting from Wisconsin across eastern Lake Superior and then into Ontario brought periods of freezing rain and moderate snow to portions of Upper Michigan from the 16th into the 17th. Observers from Newberry to Two Heart measured from 0.10 inch to 0.30 inch of freezing rain on the morning of the 16th. The Luce County Sheriff reported a widespread glaze on elevated surfaces as ice accumulation caused minor damage to tree limbs. One broken tree limb fell on a power line and started a fire.
April 17
2009: On April 17, 2009 and again in 2002, a record high temperature of 73F occurred at WFO Marquette.
2002: On April 17, 2002, the record setting snowfall in February and March set the stage for flooding in April. During February and March of 2002, north-central and western parts of Upper Michigan received over 100 inches of snowfall. The snow pack held over 11 inches of water. The snow quickly melted during a 6 day period, 11-17 April 2002, releasing all that water into the creeks, streams, rivers and lakes. To exacerbate the situation, over 2 inches of rainfall occurred 10-12 April over much of Upper Michigan, and record high temperatures in the 70s and 80s were recorded on the 15th and 16th. During those two days, a dramatic snow melt occurred with nearly 2 feet of snow melting away. To complicate matters further, moderate rain during the morning of the 18th and severe thunderstorms in the afternoon and evening dumped up to an additional 1 1/2 inches of water over an already saturated and flooded Upper Peninsula. Following the rain and warm temperatures, streams and rivers began to rise and overflow. Many local and county roads were closed due to high water and several dams were in jeopardy of failing. Localized flooding of low lying areas was common across the western and central Upper Peninsula. Major flooding on rivers and lakes occurred in 8 Upper Michigan Counties. Gogebic County was the hardest hit. A state of emergency was declared by the Governor, and the county was later declared a disaster area. The towns of Ironwood and Wakefield sustained the greatest damage. Approximately 160 homes and businesses were affected by the rising waters. Major highways US-2, M-28, and M-64 were closed and 25 local and county roads were also closed due to high water. The Black, Montreal and Ontonagon Rivers all went above flood stage. A partial failure of the Presque Isle Wildlife Dam occurred on the Presque Isle River. Heavy rains and rapid melting of the snowpack this spring contributed to the collapse of a 10 feet wide section of the earthen portion of the dam. This partial failure caused increased flows on the Presque Isle River through the town of Marenisco, 2 miles downstream. In Marquette County, rising levels on the Chocolay, Peshekee, Escanaba and Michigamme Rivers forced people from their homes and camps. Hundreds of houses experienced water damage in their basements and dozens of homes had water in their first floor. The high water and increased flow on the Carp River washed out a 65 foot section of highway M-553, closing the road until a new bridge could be built. In Ontonagon County, highway M-28 was closed for 3 days near Bergland and Merriweather due to high water, and many secondary roads were closed because of flooding and wash outs from flooding creeks and streams. Baraga and Houghton Counties experienced flooding on the Sturgeon River and other smaller creeks and streams with flooding of some local roads and structures. Menominee, Dickinson and Iron Counties had flooding along the Montreal River. Local roads were flooded and some homes and businesses had to be evacuated due to rising water. Flood waters began to recede and river levels fell sharply over the weekend of April 20. Property damage from the flooding would amount to $18.5 million.

April 18
2002: On April 18, 2002, trees were blown down along Thousand Island Lake in the mid afternoon. 1 inch diameter hail (quarter sized) was reported in Cedar River in the mid afternoon and in the late afternoon in Agate. A severe thunderstorm with gusts up to 69 mph caused a 6 inch diameter fir tree to be blown down in Au Train in the early evening. Golfball sized hail was reported (1.75 inch) 4 miles south of Mass City in the early evening. 1 1/2 inch diameter hail (ping pong ball sized) was reported 2 miles north of Pelkie, 6 miles southeast of Rockland and 2 miles southeast of Mass City in the early evening. As a low pressure system moved toward Michigan's Upper Peninsula from the northern plains, scattered morning showers gave way to afternoon sunshine. Temperatures in the warm air ahead of the storm system rose into the 70s. The strong surface heating and the approach of the warm front ahead of the low initiated severe thunderstorms over west and central Upper Michigan late in the day and into the night.

and http://www.weather.gov/arx/ThisDayInHistory
2004: On April 18, 2004, as a low pressure area from the central plains and its attendant warm front approached Upper Michigan, showers and thunderstorms developed near the Wisconsin border. The showers and thunderstorms spread northeast across Upper Michigan during the morning before weakening and ending in the afternoon. Several of the thunderstorms became severe and dropped hailstones as large as golf balls. Quarter sized hail (1 inch) fell at 0830 CST 4 miles west of Iron River and in Iron River at 1000 CST and 1.75 inch hail (golf ball sized) fell in Stambaugh at 0950 CST. Half-dollar sized hail was reported (1.25 inch) in Arnold at 1115 EST. There was a lull late in the afternoon, but the approach of a cold front set off another round of thunderstorms in the late evening. Some of these storms over western Upper Michigan also became severe, with golf ball sized hail and damaging winds. Thunderstorm wind gusts in excess of 60 mph knocked down trees in a path through Gogebic and Iron Counties into Dickinson County. A number of 6 to 12 inch diameter trees were blown down along highway U.S. 141 8 miles north of Amasa at 1957 CST. Several 6 to 8 inch diameter trees were blown down 3 miles north of Channing in the mid evening. Golf-ball sized hail (1.75 inch) was reported and several large trees were blown down in Watersmeet in the early evening. The storm system produced heavy rainfall as well as severe thunderstorms. As the low moved from the plains into the Upper Great Lakes, warm and very moist air from the Gulf of Mexico spread northeast as well. Heavy rain under the stronger storms left standing water in yards and parking lots. This first round of convection diminished during the afternoon as the storms moved east. The approach of the low pressure system's cold front then set the stage for another round of thunderstorms in the late evening. Heavy rain also fell under the most intense thunderstorms. Total rainfall amounts were excessive at many places west of Marquette and Iron Mountain. Marenisco in Gogebic County was inundated with 2.90 inches of rain. Some other impressive rainfall totals include 2.64 inches at Ironwood, 2.57 inches at Pelkie, 2.20 inches at Amasa, 2.07 inches at Baraga, and 2.00 inches at Watton. This heavy rainfall caused some minor flooding of smaller streams and low-lying areas. The runoff from the precipitation and the melting of lingering snow over the higher terrain areas caused some flooding of the larger rivers over the west half of Upper Michigan that lingered for several days after the rain ended. Minor flooding was reported along the Sturgeon River from Alston to Chassell and along the Middle Branch of the Escanaba River at Humbolt. Minor flooding was also reported along the Michigamme River from Republic to Witch Lake, along the Trap Rock River at Lake Linden, on the Chocolay River at Harvey and along the Paint River at Crystal Falls.
1995: On April 18, 1995, snow fell across northwest upper Michigan as low pressure tracked from Iowa northeast across northern lower Michigan. Heavy snow was confined to the Keweenaw Peninsula, where nine inches accumulated at Bumbletown and seven inches accumulated at Chassel. Accumulating snow fell as far east as Marquette, where nearly two inches was reported. Lightning ignited an electrical fire that damaged the McCann Elementary School in St. Ignace causing $5000 in damage.
April 19
1913: On April 19, 1913, the wood, bulk freight Uganda, while carrying corn, was bound Milwaukee for Buffalo, when struck pack ice and cut her hull 4 miles east of White Shoals, Western Straits of Mackinac in Lake Michigan.

This rain combined with snowmelt caused some flooding in Marquette County. Floodwaters made it to hundreds of residences along rivers and streams in central Upper Michigan. Marquette County had as many as 500 homes affected. Numerous roads were closed due to flooding and at least one bridge was washed out in Marquette County while Alger County had 4 secondary roads washed out. Flooding lasted for 3 days in South Republic.
1922: On April 19, 1922, the Canadian lighthouse tender Lambton, while carrying gear and passengers, was carrying relief keepers to various Canadian lighthouses when she disappeared in a spring gale somewhere between Caribou Island and Whitefish Point. Several freighters spotted the boat and later wreckage near Caribou Island in Lake Superior. A Georgian Bay paper company's tug G. R. Gray searched for her for more than a week. The lost included two young sea cadets from Soo, Ontario. All 22 people on the boat perished.

1996: On April 21, 1996, rapid snowmelt combined with rain pushed the Escanaba River above flood stage on the 20th near Cornell. Flooding occurred during this period to the Escanaba and Ford Rivers along with numerous small streams. The flooding closed up to 24 roads at the height of the flooding on the 21st and washed out several roads. The most severe washout occurred on Highway M35 near Portage Creek south of Escanaba. The flooding was confined to roads, yards and basements. Most of the damage was to washed out roads with $800,000 in property damage seen. An ice jam at the Kimberly Road bridge on the Presque Isle River near Marenisco caused flooding that closed Kimberly Road from 21st through the 25th. Heavy snowmelt resulted in flooding that closed several roads and minor property damage of $40,000 in Ontonagon County.

Marie on the afternoon of the 30th. The snow became very heavy this day when the snow diminished to flurries between 8 pm and midnight. Areas west of Munising and Escanaba received mostly snow while areas to the east received mostly rain from this storm. The highest snow total was 16 inches at Watton. The snow total was newsworthy in Marquette as the 15 inches there broke its single season snowfall record of 243.8 inches set in 1981-82 at that time. The new record was 251.4 inches. It also set a new April snow record of 43.4 inches. These have all since been broken. The 10 inches at Iron River also broke its single season snowfall record of 113.7 inches set in 1959-60.

1909: On April 30, 1909, the wood schooner-barge, 2-mast George Nester broke her towline to the steamer Schoolcraft in a spring blizzard/gale and drove ashore in the Huron Islands east of the Keweenaw Peninsula off the lighthouse in Lake Superior, where she broke up. Her crew of 7 all perished while the U.S. lighthouse tender Marigold was still attempting to rescue them.
1909: On April 30, 1909, the iron, package freight Russia, while carrying cement,dry goods and thousands of rubber overshoes, had her hull fractured in a terrific storm and she sank near Detour in Lake Huron.
