.DISCUSSION...
Issued at 134 PM CDT Sat Apr 4 2026

The wrap around moisture associated with the departing low will
bring another swath of precipitation in from the west this evening
into tonight. Precipitation will be a mix of rain and snow across
central Wisconsin, with mainly snow expected across northern
Wisconsin. Further east, conditions are expected to remain dry as
the low tracks northeast towards western Quebec. Snowfall amounts
tonight are expected to be light, with a dusting to at most a few
tenths of an inch. Snowfall amounts could approach an inch across
far northwest Vilas County with some moisture from Lake Superior.
Winds will also become gusty this evening as they turn to the
west with gusts of 20 to 25 mph expected.

Dry weather is expected for most of Sunday before a clipper
system brings a chance of rain and snow from Sunday evening
through Monday. Moisture and forcing appear to be limited with
this system; therefore, minimal impacts are expected.

An active pattern looks to set up from mid next week through next
weekend with several chances for precipitation, but details, such
as timing and precipitation type, remain uncertain at this time.
The main system in the extended that bears watching is in the
Thursday night through Friday night time frame where a swath of
significant precipitation could impact the region or just graze
the area depending on the evolution of a low pressure system
developing over the central and southern Plains.

.AVIATION...for 18Z TAF Issuance
Issued at 1222 PM CDT Sat Apr 4 2026

Low stratus and some visibility restrictions will continue across
the region with IFR/LIFR CIGs and MVFR/IFR VSBYs. After a lull in
the precipitation this afternoon, a mix of light rain and snow
will move into the area from west to east this afternoon into this
evening. Snow and IFR conditions are expected to remain longest
at RHI through late this evening before improving to MVFR.
Elsewhere, cigs will improve to MVFR from east to west late this
afternoon through late this evening. Skies are then expected to
clear late tonight into Sunday as a ridge of high pressure tracks
through the western Great Lakes.

Winds are expected to become southwest then west this afternoon
with gusts of 20 to 25 knots expected at times.

.HYDROLOGY...
Issued at 134 PM CDT Sat Apr 4 2026

Several rounds of recent rainfall have caused many area rivers to
rise to bankfull or minor flood stage. Although additional
significant precipitation is not forecast, many rivers will remain
at or slowly rise to bankfull or minor flood stage through the
week. Rivers across central and east-central Wisconsin will be at
the highest risk; however, it appears that rivers are not expected
to reach moderate or major flood stage at this time.
