Milwaukee, Wisconsin – A period of accumulating snow and sharply colder weather is expected across southeast Wisconsin late Sunday into Monday morning, creating hazardous travel conditions.
According to the National Weather Service in Milwaukee/Sullivan, rain on Sunday will transition to snow between 8 and 10 p.m. Sunday, with snowfall intensifying overnight and continuing into the Monday morning commute. The heaviest snow is expected between midnight and 6 a.m. Monday, before tapering off later in the morning.
Snowfall totals are expected to range from 2 to 4 inches north of Interstate 94, including areas near Madison, Fond du Lac, Portage, and Beaver Dam. South of I-94, including Milwaukee, Racine, and Kenosha, 1 to 3 inches of snow is forecast, with lower amounts closer to the Illinois border.
Strong northwest winds gusting 30 to 35 mph are expected to develop late Sunday night and continue into Monday morning. These winds will cause blowing and drifting snow, particularly in open and rural areas, leading to reduced visibility at times.
Another concern is a rapid drop in temperatures Sunday night. As colder air moves in behind the system, wet roads may freeze quickly, resulting in slick and icy conditions even where snowfall totals are modest. Temperatures early Monday morning are expected to fall into the upper teens to lower 20s.
A Winter Weather Advisory is in effect from 9 p.m. Sunday through noon Monday for much of southeast Wisconsin. The National Weather Service advises travelers to plan for deteriorating conditions overnight and allow extra time for the Monday morning commute.
Officials urge residents to monitor forecast updates, avoid unnecessary overnight travel if possible, and be prepared for changing road conditions. While snowfall amounts may still shift slightly, confidence is high that travel impacts will occur, especially late Sunday night into early Monday.
