The Midwest is entering an active midweek weather pattern that will bring multiple systems through Wisconsin, beginning with rain on Tuesday, transitioning to snow in southeastern areas near Lake Michigan, followed by a reinforcing snow-producing system on Thursday that may impact much of the state.
On Tuesday, milder air ahead of the first system is expected to support widespread rain, particularly across southern and eastern Wisconsin, including Milwaukee, Racine, Kenosha, and Sheboygan. Temperatures are forecast to climb into the 40s, allowing precipitation to remain liquid for much of the day. Wet roadways and reduced visibility are possible during periods of steady rain.
By Tuesday night into Wednesday, colder air wrapping in from the northwest may cause rain to change over to snow, especially across southeastern Wisconsin and areas closer to Lake Michigan. Lake influence could enhance snowfall at times, leading to localized slick spots, particularly on untreated roads and bridges. Farther inland, precipitation may end more quickly or remain lighter.
Attention then turns to Thursday, when a stronger, reinforcing system is expected to move through the region. This system has a higher likelihood of producing snow across much of Wisconsin, including central and northern areas as well as southern cities such as Madison, Green Bay, Eau Claire, and Wausau. Snowfall amounts remain uncertain, but broader coverage and longer duration increase the risk for travel impacts statewide.
The primary concern is the cumulative effect of multiple systems. Falling temperatures, lingering moisture, and fresh snowfall could lead to slick roads, reduced visibility, and difficult travel, especially during morning and evening commutes.
Residents are encouraged to monitor updates closely, as small shifts in storm timing or intensity could significantly alter snowfall totals and impact levels across Wisconsin.
