Wintry Mix Could Bring Snow, Rain, And Icy Roads To Wisconsin Tuesday

MILWAUKEE, WI — A round of light snow will move across southern Wisconsin tonight, followed by a more complicated winter storm Tuesday into Wednesday that could bring a mix of rain, snow, and minor icing. Forecasters say the exact placement of the rain–snow line remains highly uncertain, and even a small shift in the track could significantly change who ends up shoveling.

Light, fluffy snow tonight will bring minor accumulations, with most areas south and west of the I-94 and I-39 corridors seeing less than an inch. East-central Wisconsin, including Fond du Lac, Sheboygan, West Bend, Beaver Dam, and Montello, has the highest chance of reaching around an inch.

The main system arrives Tuesday afternoon and continues into Wednesday. A wintry mix is expected across southern Wisconsin, with a transition zone of rain, snow, and brief icing setting up somewhere between Madison and the Fox Valley. Forecasters say that subtle north–south shifts in the system could dramatically alter snowfall totals.

Northern portions of the region, including Fond du Lac, Sheboygan, Waupun, Berlin, Montello, West Bend, and Beaver Dam, have the highest likelihood of accumulating snow. These areas carry a 50 to 60 percent chance of receiving at least 2 inches, with some potential for 4 inches or more if the rain–snow line sinks slightly south.

Farther south, including Milwaukee, Waukesha, Racine, Kenosha, Janesville, and Madison, current projections show totals closer to a dusting to 2 inches, but these numbers could rise if the system trends colder.

Forecasters also note that rain falling on cold pavement may lead to slick spots Tuesday evening and Wednesday morning, especially within the transition zone.

The National Weather Service urges Wisconsin residents to monitor updated forecasts and prepare for changing conditions during the Tuesday evening and Wednesday morning commutes.
