Next 12 Hours
Look for light snow, freezing rain and rain Thursday into Friday as a storm system moves through south-central Wisconsin, with the coldest air of the season to follow, according to forecasters.
Snow accumulations are expected to be “light,” according to the National Weather Service, but that could change if the track of the storm system shifts.
In Madison on Tuesday, frosty pavement was leading to slippery conditions on some less-traveled roads across southern Wisconsin, the Weather Service said.
However, that won’t last as the forecast calls for sunny skies, highs in the lower 40s and northwest winds at 5 to 15 miles per hour.
After an overnight low in the lower 20s, Wednesday should be mostly cloudy, with highs around 30 and northeast winds at 5 to 10 mph.
The low overnight Wednesday into Thursday should be in the mid-20s, before the storm moves in on Thursday.
The Weather Service said chances for precipitation are 70 percent Thursday, 80 percent Thursday night, 60 percent Friday and 20 percent Friday night, in the form of light snow, possibly mixed with freezing rain in the morning and rain in the afternoon on Thursday; snow, possibly mixed with freezing rain through around midnight, then light snow after midnight, overnight Thursday into Friday; and light snow Friday into Friday night.
Snow accumulation should up to 1 inch Thursday, then light Thursday night and Friday.
Skies over Madison should be cloudy Thursday and Friday, partly sunny Saturday, mostly cloudy Christmas Eve, and partly sunny on Christmas, with highs in the mid-30s Thursday and Friday, lower 20s Saturday, around 16 Sunday, and around 10 Monday, and overnight lows in the upper 20s, and around 19, 7 and 3.
27 Storm Track meteorologist Branden Borremans forecasts a beautiful December Tuesday; light snow developing Thursday, with a wintry mix southeast of Madison; periods of light snow and flurries Friday; then quiet but much colder weather.
