.KEY MESSAGES...

- Slippery conditions from last night`s snow and patchy freezing
  drizzle may extend into this morning`s commute, especially on

  system has the potential to bring minor snow accumulations and
  gusty winds, followed by a brief return to colder temperatures.

  warmest days occurring Thursday and Monday, when some locations
  may reach the lower to middle 30s.

.DISCUSSION...
Issued at 252 AM CST Mon Feb 2 2026

Light snow over eastern WI will continue to shift east early this
morning as a short-wave and associated cold front move out of the
region. Scattered lake-effect snow showers will linger across far
NC WI during the day, and probably into tonight. Otherwise
scattered flurries and patchy freezing drizzle (across the far
south part of the forecast area) should taper off around daybreak.
Slippery roads from last night`s snow and patchy freezing drizzle
may linger into the morning commute, especially on any untreated
secondary roads. Overcast conditions should give way to a few
breaks as the day wears on, and this should help boost
temperatures into the upper teens and lower 20s northwest to the
middle to upper 20s elsewhere. More widespread clearing occurs
tonight, except in far NC WI, where some lake-effect clouds
persist. Partly cloudy skies and light winds should allow
temperatures to drop into the single digits above and below zero.

A period of high pressure will bring dry conditions Tuesday through
Wednesday night as the upper-level pattern re-amplifies. An upper
ridge strengthens over the western U.S. while a mean trough
reinforces itself over the East. This set-up will pave the way for
another clipper system Thursday into Friday. Model trends are
leaning toward a farther north track through Ontario with this
system; perhaps as far north as Hudson/James Bays. If this occurs,
would expect less snow and a bit warmer temperatures. Gusty NW-N
winds would still occur on Friday, but with a lower chance of
gales on Lake Michigan.

Temperatures remain on the milder side through most of the
period, with highs mainly in the 20s, and even some lower to
middle 30s in C/EC WI Thursday and Monday. A brief shot of below
normal temperatures arrives in the wake of the late week clipper
system, but temperatures should rebound a bit by the end of the
weekend.

.AVIATION...for 18Z TAF Issuance
Issued at 1113 AM CST Mon Feb 2 2026

VFR status is lingering over much of the region late this morning
with gradual clearing being to occur across central WI. Clouds
should continue to clear out across much of the region this
afternoon, except across north-central where lake induced MVFR/VFR
status will linger longer.

Where clouds are present early this afternoon snow flurries will be
possible, however, based on current surface ob trends any flurries
should have little impact on vsbys. Light lake effect snow may also
linger through the afternoon across north-central WI, including
RHI, with brief periods of 5-7SM visibility.

Light northwest to north winds are expected through the TAF period.
