.DISCUSSION...
Issued at 147 PM CST Fri Feb 27 2026

A mild afternoon across the region with temperatures in the middle
40s to middle 50s. For tonight, gusty winds can be expected as a
strong cold front moves across the region. Temperatures will drop
into the single digits north to the the teens across east-central
WI. High temperatures on Saturday will be around 30 degrees colder
with readings in the middle teens to middle 20s. The other story
for Saturday will be a clipper system that will pass south of the
area. There is a 50-80% chance of snow, mainly south of Highway
29 where 1 to 3 inches of snow is anticipated. Within this band
of snow across, a narrow 2-3 county wide band of heavier snow
with 3"+ is expected to set up. Current indications that the band
of heavier snow is forecast to set up south of the area, in the
axis where the best fgen forcing set ups. Any lingering snow
should end across east-central WI Saturday evening. Despite
almost being March 1, the snow will be powdery type snow although
winds should not be a factor for blowing snow.

Tranquil weather is expected through Monday, although it will
remain cold on Sunday with highs in the 20s before warming into
the 30s on Monday. Beyond Monday, more typical spring like
temperatures in the 30s and 40s is expected through next Friday.
Along with the warmth will come chances for rain and snow,
especially later next week. The beneficial precipitation should
hopefully help alleviate the long-term precipitation deficits of
the current drought. Will also need for the ground to thaw to
allow the moisture to replenish soil moisture and ground water
tables.
