Wisconsin – A quiet, cool start is quickly giving way to a fast-moving spring setup, and roads across northeast Wisconsin could turn slick within days as rain flips to snow and ice. The air feels calm now, but changes are already lining up.
According to the National Weather Service in Green Bay , scattered thunderstorms are expected to develop later today into the evening. A few storms may produce small hail and brief heavy rain, especially across Brown, Outagamie, and Winnebago counties. Keep an eye on skies if heading out by late afternoon.
Storm chances increase again Tuesday, with stronger cells possible. Gusty winds and pockets of heavy rain could slow travel on I-41 and Highway 29 by midday into the evening hours. Plan extra time and watch for sudden downpours reducing visibility.
Then comes a sharp shift. By Wednesday night into Thursday morning, colder air wraps in. Rain begins mixing with snow, sleet, and freezing rain. Even a light glaze can create hazardous driving, especially on bridges and untreated roads. This is prime time for early spring “flash freezing,” where wet pavement quickly turns slick as temperatures drop near freezing.
Temperatures fall from the low 50s today to the upper 30s by Wednesday, reinforcing that winter is not fully done yet. Keep winter gear within reach and check tires before midweek travel.
Conditions improve slightly by Friday with lingering rain or snow showers, but roads may stay damp and chilly.
