GREEN BAY, Wis. – Eastern Wisconsin wakes up to a wet, breezy start this weekend as fall showers and scattered thunderstorms roll through the region before calmer, cooler air settles in by Monday. The National Weather Service in Green Bay reports that gusty winds and moderate rain may impact travel along I-43, U.S. 41, and nearby rural routes through late Sunday.
According to the National Weather Service, rainfall totals could reach a half inch in some spots, with brief downpours and lightning possible. Drivers should slow down on slick roads and use extra caution through Sunday afternoon as winds shift northwest behind the passing front. Gusts may reach 30 mph at times, especially across open stretches near the bay and Lake Michigan shoreline.
Skies will clear by Sunday night, giving way to a brighter, calmer start to the workweek. Monday brings sunshine and highs in the low 60s, perfect for outdoor errands, football practices, or a trip to fall markets. However, forecasters warn that another round of showers could return Monday night into Tuesday, followed by a notable drop in temperatures that signals the season’s next cold snap.
The week’s second half looks crisp but quiet, with sunshine and lows near freezing possible north of Green Bay by Wednesday morning—a reminder that frost season is arriving across northern Wisconsin just in time for late-October leaf cleanup and Halloween decorating.
