A powerful winter storm that started pummeling southern Wisconsin Monday evening will dump more snow on the area on Tuesday, with strong winds causing blowing and drifting snow that will make for treacherous travel conditions, according to forecasters.
As of about daybreak, snow totals reported by the National Weather Service included 5.7 inches at the Dane County Regional Airport, 5.1 inches in Fitchburg, 5 inches in Baraboo, 6.7 inches in Mequon, 5.1 inches in Pardeeville, 7.6 inches in La Crosse, 8 inches in Monroe and Onalaska, and 5 inches in Hubertus and Bay View.
The heaviest snow was expected to be over by around sunrise, but more bands of lighter snow were expected later in the day, with the snow moving from southwest to northeast. Another 2 inches or more could fall during the day and winds gusting as high as 35 miles per hour will cause blowing and drifting snow that will make for hazardous driving conditions.
The latest road conditions are available by calling 511 or by going to the state’s road conditions website.
The heaviest snow totals were predicted for north of the Madison area, with far southern and southeast Wisconsin expected to end with lower totals with sleet and freezing rain occasionally mixing in with the snow, the Weather Service said.
Officially, the winter storm warning for most of Wisconsin runs until midnight.
