Any snow accumulations will likely be under one half inch. - Light snow may occur Friday afternoon and evening, with the passage of an Arctic cold front. - An Arctic airmass is expected this weekend, with wind chills as cold as 15 below to 30 below zero for the overnight and early morning hours. && .SHORT TERM... Issued 315 AM CST Thu Dec 11 2025 Today and tonight: Stubborn low clouds may hang on across much of southern Wisconsin through early to mid-morning. Models keep trying to show the clear slot expanding farther into the forecast area, but satellite trends don`t reflect this potential through the next couple hours. Will continue to monitor the back edge of the clouds near Eau Claire this morning to see if there is a significant southward push. These clouds have kept temps from falling as much as expected across much of the area early this morning, so will continue to modify short term temps to match the slower exit of the clouds. High temps may have to be updated for today if the clouds hang on through early to mid- morning, as temps are trending towards starting out warmer at daybreak than the current forecast highs. Otherwise, expect quiet weather today under high pressure, with light winds through tonight. It sill looks like there could be a little light snow southwest of Madison this evening into early tonight, though some forecast models keep the snow completely southwest of the state. If the snow does sneak into southwest Wisconsin, only a dusting to a half an inch is expected. DDV && .LONG TERM... Issued 315 AM CST Thu Dec 11 2025 Friday through Wednesday: Another shortwave is expected to move through Friday, with models still suggesting a little light snow possible in the afternoon and evening. 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, though latest forecast models largely keep the snow south of the state line. 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. DDV && .AVIATION...

A period of west to northwest gales may return Friday night through Saturday night as a strong Arctic cold front moves through the region. Heavy freezing spray will likely develop during this period as the colder airmass moves in. Strong high pressure around 30.8 inches will then move southeast through the region Sunday and to the south early next week. Gusty winds may return early next week behind the exiting high.
