Wisconsin wakes to a bitter December chill, with frost clinging to windshields and sidewalks crunching underfoot. That deep cold eases briefly, but winter is far from finished. A developing midweek system brings rain, snow, and another sharp freeze to Milwaukee by Thursday.
According to the National Weather Service, temperatures recover into the upper 30s by Wednesday as clouds increase. Roads improve during the day, but that break is short-lived. By Wednesday night, rain chances rise, especially south and east of the city.
Conditions deteriorate Thursday. Rain arrives early, then mixes with snow as colder air pushes in. Highs struggle to reach the lower 40s before temperatures begin falling. Gusty winds may develop, reducing visibility and making travel tricky on I-94, I-43, and area bridges.
By Thursday night, colder air fully settles in. Temperatures drop into the low teens, with wind chills making it feel colder. Any leftover moisture on pavement is likely to refreeze quickly. Black ice becomes a major concern, especially after sunset and during early morning drives.
Drivers should slow down, increase following distance, and avoid sudden braking. Side streets and ramps may become slick first. This is a classic flash-freeze setup following daytime precipitation.
Friday stays cold but quieter, with sunshine returning and highs near 25. The weekend remains wintry, though calmer, with highs rebounding into the upper 30s by Saturday. Meteorologists say this pattern signals a firm shift into early winter as Christmas travel approaches.
Residents should use this window to prepare vehicles and travel plans. Winter has clearly taken hold along Lake Michigan.
