.UPDATE...
Issued 1027 AM CST Wed Dec 10 2025

The lingering light snow will quickly push south of far
southeast Wisconsin in the next hour. Gusty north to northwest
winds will then linger through today, with cloudy skies. There
is around a 20 percent chance for light snow or flurries to
affect southwest portions of the area this afternoon into this
evening, as some differential CVA pushes southeast through the
region. There is some dry air that this will need to overcome,
so not expecting much if any accumulation. There may be some
flurries in northeast parts of the area as well into this
afternoon, as some light snow showers shift southeastward.

.SHORT TERM...
Issued 406 AM CST Wed Dec 10 2025

Today and Tonight:

A final round of accumulating snow will drop through southern
Wisconsin this morning on the back side of low pressure. Up to
an inch of additional accumulation is possible. Not out of the
question to see a little freezing drizzle ahead of the snow
before better saturation aloft occurs in the ice growth region.
Northerly winds will pick up this morning as well as colder air
wraps in behind the low. Given the wintry weather and blustery
winds expected during the morning commute, opted to extend the
Winter Weather Advisory for western areas until 9 am, keeping
the 9 am expiration for eastern counties.

Snow will come to an end by late morning, with dry weather
expected into the afternoon. Could see a little light snow in
southern and western portions of the forecast area late
afternoon into early evening as a weak shortwave rolls through.
Will see a dusting at best with this round. Colder air will
continue to push in tonight, with temperatures dropping into
the single digits by daybreak. Light winds and clearing skies
are also expected, so could see temps even dip below zero by
morning.

.LONG TERM...
Issued 406 AM CST Wed Dec 10 2025

Thursday through Tuesday:

Dry weather and well below normal temps are expected under
high pressure Thursday. It still looks like light snow may clip
the southwest forecast area Thursday night, as a shortwave zips
through the region. Will have to keep an eye on model trends
with this system, as a wobble north could bring a couple inches
of accumulation into at least the southwest.

Another shortwave is expected to move through Friday, with
models suggesting a little light snow possible. Even colder
temps will move in behind this wave, with highs likely not
getting out of the single digits over the weekend. Lows will be
below zero at night, with wind chills of 15 to 30 below. Cold
weather headlines will be possible both Friday night and
Saturday night, with the coldest wind chills expected Saturday
night into early Sunday. Another wave may clip the area on
Saturday, with more snow chances possible.

Winds will become southerly Monday into Tuesday on the back
side of high pressure and as a trough of low pressure approaches
from the west. This should result in warming temps early next
week, with highs back around normal by Tuesday.

.AVIATION...
Issued 1027 AM CST Wed Dec 10 2025

The light snow will quickly push south of Kenosha in the next
hour. Gusty north to northwest winds will then linger through
today, with ceilings varying from 1000 to 3000 feet AGL.

There is around a 20 percent chance for light snow or flurries
to affect areas southwest of Madison this afternoon into this
evening. There is some dry air that this will need to overcome,
so not expecting much if any accumulation. There may be some
flurries in northeast parts of the area toward Sheboygan as
well into this afternoon, as some light snow showers shift
southeastward.

Gusty northwest winds into this evening will gradually weaken
by later tonight, then shift west to southwest on Thursday. The
ceilings should gradually clear out of the area as well by later
tonight into Thursday morning, before more middle to high clouds
move in Thursday afternoon. Any light snow later Thursday
afternoon should remain west of Madison and Janesville. These
sites may see light snow with perhaps an inch or two of snow
accumulation Thursday evening.

.MARINE...
Issued 1027 AM CST Wed Dec 10 2025

North to northwest gales will continue today across the
southern two thirds of the open waters of Lake Michigan, behind
departing strong low pressure around 29.2 inches. The brisk
winds will gradually diminish tonight, as high pressure around
30.1 inches approaches from the west.

A Gale Warning is also in effect for the nearshore waters of
Lake Michigan until 12 PM CST. A Small Craft Advisory will then
be needed this afternoon into this evening, for lingering gusty
northwest winds and elevated waves.

A period of northwesterly gales may then return Friday night
into Saturday, as a strong Arctic front moves through the Great
Lakes region. Heavy freezing spray may also develop later this
week into the weekend, as the colder airmass moves in.
