We are preparing for a moderate winter storm this evening through the end of the workweek. While this storm will not be extreme, Wisconsinites will have plenty of shoveling and snow blowing to do come tonight and tomorrow morning.
*Winter Weather Advisory for all counties other than Vilas, Oneida, Forrest, and Florence for this afternoon and Friday
Today: Grey skies and fog to start then an 80% chance of snow showers in the late afternoon.
Timing: Starting around 4 PM (South/Central Wisconsin)
High: 33 Wind: SE 5-15
Tonight: Cloudy with snow showers. 2 to 5 inches accumulation likely widespread.
Low: 31 Wind: NE 8-12
Friday: Cloudy with scattered snow possible. Another inch is projected in spots especially north.
High: 33 Wind: NE 8-12
Our morning will start fairly typical with gray skies and the occasional patch of fog here and there. New forecasts have now delayed the snow showers to the late afternoon, so don't expect to see much winter weather until the early evening. The first half of the day will also be quite mild, with temperatures in the low 30s, and winds will be from the east southeast around 10 miles an hour.
As we transition to the early evening, the winter weather will begin to take full effect. Showers will likely begin around 3-5 PM, bringing moderate snowfall to all areas of north-central Wisconsin. With highs in the mid-30s, some snowfall will become quite wet and slushy, turning to a mix, especially to the southwest. Otherwise, snow showers should remain fairly constant, leaving 2-3 inches before the nighttime hours. The evening commute will likely be affected, so it is advised to slow down or leave work early if possible.
Snow showers will continue overnight into Friday before they become more isolated. We expect to pick up another 2 inches in the overnight hours, so even if the sidewalks are shoveled this evening, they will need to be shoveled Friday morning again. Temperatures overnight will be extremely mild, remaining in the low 30s, and winds will likely turn to the east.
Friday, the snow system will still be in the area; however, the rotational nature of the storm will likely make showers much more isolated. Scattered showers are expected through the day here and there, especially to the north. Temperatures will once again be approaching the mid-30s, so there may be some isolated wintry mixes or freezing rain events. Roadways on Friday are expected to be extremely slick; however, travel will still be possible with extra caution. Areas may accumulate another inch in spots throughout Friday.
The overall snowfall totals for the area will range, though it does seem like most areas will see 3-5 inches of snowfall across the 2 days. Some isolated areas will receive a bit more, and the NW could see up to 7 inches given the higher chance of snow on Friday.
The weekend will remain cloudy with a 20% chance of residual light snow of flurries both Saturday and Sunday. Following the weekend, conditions will be returning to normal for January, with temperatures in the low 20s.
Enjoy your Thursday and stay safe this evening! Meteorologist Jackson Garlock 14-January 2021
On this day in weather history:
1989 - A winter storm spread snow and sleet and freezing rain from the Middle Mississippi Valley to the northeastern U.S. Freezing rain in West Virginia caused fifteen traffic accidents in just a few minutes west of Charleston. Tennessee was deluged with up to 7.5 inches of rain. Two inches of rain near Clarksville TN left water in the streets as high as car doors.
