.SHORT TERM...
Issued 210 AM CST Tue Dec 2 2025

Today and Tonight:

The light snow that affected the region Monday afternoon and
evening has moved east as of early this morning. A few breaks in
the clouds are occurring across southeastern Wisconsin, but
additional stratus is moving in from the west. Partly to mostly
cloudy conditions are expected today, with highs in the mid 20s.
No additional precipitation is expected.

Increasing southerly flow tonight will keep temperatures from
falling much, with overnight lows generally in the upper teens
to around 20. Wind chills will be in the upper single digits to
low teens. Light snow will move in from the north toward
daybreak on Wednesday, along and ahead of a cold front.

.LONG TERM...
Issued 210 AM CST Tue Dec 2 2025

Wednesday through Monday:

Breezy winds are expected with the frontal passage on Wednesday,
along with continued chances for light snow. While most of the
area should see at least a few flakes, QPF and thus snow amounts
look very light; generally less than a half inch. Highs on
Wednesday will likely occur around noon, with temperatures
falling through the 20s during the afternoon hours.

High pressure moves toward the area Wednesday night into
Thursday morning, with clearing skies. This will set the stage
for a very cold start to the day on Thursday, with morning lows
across the east between 0 and -5, and -5 to -10 across the
western portions of the forecast area. Wind chills look to stay
just above advisory levels, but will still be very chilly, with
readings around -15.

Cold temperatures continue Thursday and Thursday night, with
highs on Thursday around 10, and lows Thursday night a few
degrees on either side of zero.

Extended guidance continues to point toward a period of active
northwest flow Friday into next week, with shortwave passages
every day to every other day. Very tough to nail down specific
details regarding strength of these shortwaves and resulting
precipitation at this distance, but the overall pattern would
suggest increased potential for below average temperatures as
well as additional chances for light snow.

.AVIATION...
Issued 210 AM CST Tue Dec 2 2025

IFR stratus will affect many of the terminals this morning,
though may remain just west of Milwaukee and Kenosha. These
clouds should scatter out in a few locations at least briefly
today, though a mix of IFR, MVFR and VFR ceilings will likely
persist for much of the day across southern Wisconsin.

Winds today and tonight will be from the southwest, with some
gustiness noted tonight as winds increase ahead of a cold front.
That front will turn winds to a more westerly and then
northwesterly direction heading into Wednesday morning. Light
snow will move toward the terminals from the northwest very late
tonight into Wednesday. Amounts will remain light (less than a
half inch), but some visibility restrictions will remain
possible.

.MARINE...
Issued 210 AM CST Tue Dec 2 2025

A strong cold front along a low pressure trough averaging 29.8
inches will cross Lake Michigan Wednesday. Gusty southwest winds
are expected ahead of this front early Wednesday morning, with
gusty northwest winds behind it Wednesday afternoon and night. A
Small Craft Advisory is in effect for the nearshore waters
starting tonight and continuing until Thursday morning. Over the
open waters, winds will remain just below gales for most of the
lake, though a brief period of low end gales is possible
Wednesday night over the far northern part of the lake. Very
cold air with this system will result in a risk for freezing
spray Wednesday night and Thursday.

Light winds are expected Thursday with the influence of high
pressure of 30.4 inches over Illinois and Indiana. Another period
of elevated southwest winds will occur Thursday night into Friday
as another low pressure trough around 29.8 inches crosses the
Upper Great Lakes.
