KEY MESSAGES

- A brief round of snow is expected mainly north of I-94 this afternoon, from 2 to 6 pm. Totals up to a half an inch (locally as high as an inch) are most likely for areas from Marquette through Sheboygan counties. Some freezing drizzle may mix in farther south towards I-94. The quick hitting snow and potential glaze will likely result slick spots for the afternoon/evening commute, especially on any untreated roads.

- A dusting of snow is possible in the north on Thursday

- Mild and breezy conditions are expected for Friday

SHORT TERM

Issued 1245 PM CST Tue Feb 24 2026

Tonight through Wednesday night:

A shortwave and associated cold front will push through southern Wisconsin mid to late afternoon today. A quick round of precip is expected with this system, mainly in the form of snow north towards the Fond du Lac and Sheboygan areas. Farther south on the tail end of the line of precip towards the I-94 corridor, the snow may mix with or change over to freezing drizzle for a time. This is due to the better forcing combining with pockets of drier air and thus a lack of ice crystals. There have been reports of a light glaze in spots upstream in southern Minnesota, so will continue to monitor the line of precip as it approaches the forecast area. Where the precip does remain snow, totals of around a half an inch are likely, with up to an inch not out of the question. The timing of the light snow accums and possible light glaze will correspond with afternoon commute traffic, as the band should slide through northwest to southeast between 2 and 6 pm.

Dry weather is expected tonight and Wednesday behind the departing shortwave and ahead of approaching high pressure. A colder airmass will move in behind the cold front tonight, with lows in the teens again most places and below normal highs tomorrow in the mid 20s to around 30.

LONG TERM

Issued 1245 PM CST Tue Feb 24 2026

Thursday through Tuesday:

Some sunshine is expected to start the day Thursday under surface high pressure, with increasing clouds late morning into the afternoon as a weak shortwave moves through. Kept a slight chance (<30%) of snow north of I-94 with this shortwave, with a mix of model solutions on whether or not this wave will produce precip in the forecast area.

A brief warmup is likely Friday as southerly low level flow increases ahead of a low pressure system passing by well to the north. Should be enough sunshine to combine with the mild south winds for well above normal highs in the mid 50s most places. The cold front associated with the low will move through Friday evening, resulting in temps returning to around normal for Friday night and Saturday.

Another shortwave sliding through late Saturday into Saturday night will bring a reinforcing shot of colder air along with a chance for a dusting of snow. Highs Sunday behind this shortwave will likely only top out in the mid 20s to around 30.

Temperatures early next week are expected to gradually return to around or just above normal, with the active shortwave pattern brining more precip chances at times.

AVIATION

Issued 1245 PM CST Tue Feb 24 2026

A quick round of precip is expected across southern Wisconsin this afternoon from around 20Z to 00Z. The precip should be mainly in the form of snow north towards the Fond du Lac and Sheboygan areas. Farther south on the tail end of the line of precip towards the I-94 corridor, the snow may mix with or change over to freezing drizzle for a time. There have been reports of a light glaze in spots upstream in southern Minnesota, so will continue to monitor the line of precip as it approaches the forecast area. Where the precip does remain snow, totals of around a half an inch are likely, with up to an inch not out of the question with snowfall rates up to 0.5" an hour. Lower ceilings (1-3 kft) and visibilites (1-4 SM) are most likely across the northern forecast area from Marquette through Sheboygan counties.

Dry weather is expected tonight and Wednesday behind the departing shortwave and ahead of approaching high pressure. Clearing skies are likely south of I-94, with lingering clouds tonight into Wednesday in the north. May see some MVFR ceilings linger in the north through at least Wed morning.

Breezy southwest winds this afternoon will become west to northwest this evening behind the cold front, remaining breezing out of the northwest on Wednesday.

MARINE

Issued 1245 PM CST Tue Feb 24 2026

Southerly gales will continue across the open waters this afternoon as low pressure of 29.2 inches just north of Lake Superior continues eastward. Winds will become west to northwest behind the associated cold front this evening and overnight, while remaining breezy (though below gale force). The Small Craft Advisory continues into mid-morning Wednesday.

Lighter winds are expected Wednesday night into Thursday, as high pressure of 30.0 inches moves into the area. South to southwest winds will then pick up later Thursday into Friday ahead of an approaching low and the departing high. A Small Craft Advisory may be needed for this period, with a few gales not of question across northern portions of the lake.
