.DISCUSSION...
Issued at 326 PM CDT Mon Mar 16 2026

Historical snowstorm coming to an end this afternoon and evening,
before providing Green Bay with the 2nd biggest snowstorm on
record at 26.1 inches as of 1 pm. Totals could go a few tenths
higher with the evening observation.

Calls to local sheriff departments indicated road conditions were
not great due to the snow and blowing snow. With this in mind,
will extend a Winter Weather Advisory for the afternoon and
evening commute across northeast WI. Clouds and winds will be on
the decrease through the night, with very cold temperatures
for the middle of March with lows in the single digits above and
below zero. Wind chill readings down to zero to 15 below should
be expected Tuesday morning.

Tranquil conditions expected Tuesday as the next clipper system
approaches from the west. This system will bring a 40-80% chance
of light snow Tuesday night into Wednesday. Snowfall totals around
an inch or less are expected. Otherwise, no significant weather
is expected through next weekend. Temperatures will remain well
below normal on Tuesday with more typical spring like temperatures
Wednesday into the weekend. Snow melt later this week will result
increasing fast flows and rising river levels. Will continue to
monitor rivers to see if a few of them reach at least bankfull if
not minor flood stage.
