.DISCUSSION...
Issued at 203 AM CST Wed Feb 11 2026

Light lake effect snow showers and flurries will come to an end
across far north-central Wisconsin early this morning. High
pressure building over the northern Plains will then slide east
dominating the region through the end of the work week. The
weather is expected to remain dry through the first half of the
weekend. A weak frontal boundary will bring a low end (~10%)
chance for light precipitation Saturday night into Sunday. NWP and
ensembles indicate a better chance (40-60%) for a widespread
precipitation event sometime during the middle of next week. There
is still quite a bit of uncertainty regarding precipitation type
from this next event given the model discrepancies in
temperatures.

Temperatures will begin to trend warmer than normal Thursday with
a 40-80% chance of highs above 40 degrees as soon as Friday and a
50-90% chance by Sunday. There is a 30-50% chance that areas
south of HWY 29 reach 50 degrees by early next week. The warming
trend will lead to a quickly melting snowpack and deteriorating
ice conditions, which does raise the concern for ice jams next
week. Additionally, the melting snowpack will lead to an increase
in low-level moisture increasing the possibility of periods of
fog this weekend and into next week.
