Green Bay, Wis. – Thunderstorms may clip northeast Wisconsin tonight before skies turn sunnier and cooler heading into Labor Day weekend. Drivers on I-43 near Green Bay should watch for patchy fog and slick conditions as storms move through after midnight.
According to the National Weather Service in Green Bay, storms remain scattered and not expected to turn severe. Rain chances hold near 30 percent tonight, with a low around 58 degrees. By Thursday morning, clearing skies will dominate, although a north wind gusting up to 18 mph could make conditions feel cooler.
Hazards extend beyond rain. The weather service warns of building waves Thursday afternoon on Lake Michigan, creating dangerous swimming and boating conditions south of Kewaunee. In addition, areas of frost may develop across north-central Wisconsin late Thursday night as temperatures dip into the upper 30s.
By Friday, sunshine returns with highs near 68 and light north winds, setting the stage for a calm start to the holiday weekend. Saturday and Sunday both look sunny and mild, with highs climbing back into the 70s.
Travelers should prepare for changing conditions tonight, avoid unnecessary late-night driving in fog, and exercise caution on Lake Michigan Thursday. The pattern favors dry weather for outdoor events, but chilly nights will require jackets and blankets for camping.
Conditions improve for the long weekend, but advisories may still be issued if frost expands farther south. Residents can expect a pleasant stretch once storms clear.
