Full Notification

A strong late season winter storm will bring a widespread 5 to 7 inch snowfall to southern Wisconsin Saturday into Saturday evening. A very narrow band of higher amounts is possible. The snow will start in the Madison area and points west during the mid morning hours and continue through the early evening. Across the southeast, including the Milwaukee metro area, look for a late morning or early afternoon start time, continuing through the late evening. Snowfall rates during the afternoon will likely reach 1 inch per hour. Warm pavement temperatures will cause a rapid slushy accumulation that will be difficult to travel in. Temperatures falling below freezing Saturday night will cause any standing water and slush to freeze. The higher snow accumulations will occur on grassy and elevated surfaces. Sunshine and temperatures in the 40s on Sunday will cause a lot of the snow to melt, especially on roads and sidewalks. Though the impact on Saturday will be high, it will be short lived due to improving conditions on Sunday.
