Milwaukee, WI – A band of steady light snow is expected to develop tonight across portions of southern Wisconsin, creating slushy accumulations and potentially slick travel conditions heading into the Tuesday morning commute, according to the National Weather Service (NWS) in Milwaukee/Sullivan. The highest impacts are projected for areas north and west of Madison, where accumulating snowfall is most likely.
According to the NWS, road temperatures will be cold enough for slush to stick, especially on untreated surfaces, bridges, and elevated roadways. Snowfall rates may reach 0.5 inches per hour at times between 9 p.m. tonight and 10 a.m. Tuesday, leading to localized slick spots even with relatively light totals. A wintry mix or light snow is expected outside the main snow band, with little to no accumulation expected there.
The area of greatest concern is highlighted in red on the NWS impact map—indicating a greater than 70% chance of accumulating snow. This zone includes communities from Wisconsin Dells eastward toward Beaver Dam, Columbus, and parts of Dodge and Sauk counties. The band could wobble north or south overnight, meaning the exact placement of slick roads may shift before sunrise.
Drivers traveling early Tuesday should plan on slower conditions and use extra caution on rural stretches and elevated surfaces. Visibility may also briefly lower within heavier bursts of snow. Forecasters will update impacts as the event evolves, and commuters are encouraged to check conditions before heading out.
Travelers in the Milwaukee metro may see lighter impacts, though a light wintry mix could still create patchy slick spots.
