Green Bay, Wisconsin — Northeast Wisconsin is heading into one of the wetter stretches of the summer so far, with rain chances climbing as high as 90% Tuesday and Wednesday — and temperatures dropping well below what’s normal for mid-June.

The National Weather Service has flagged multiple rounds of showers and thunderstorms moving through the region this week, with the heaviest impact expected midweek.

Monday: The Calm Before the Storm

The week opens with a moderate chance of afternoon and evening thunderstorms, with rain probabilities sitting between 30% and 50%. Highs will reach 72 to 78 degrees across Green Bay, Appleton, Oshkosh, Manitowoc and surrounding communities — still comfortable, but a sign of what’s coming.

Tuesday and Wednesday: Peak Rainfall Risk

This is when conditions turn. Rain probabilities surge to 60%–90% across the region, with widespread showers and thunderstorms expected to impact travel, outdoor work and daily routines. Highs drop to 66–75°F Tuesday and fall further Wednesday, ranging from just 65 to 72 degrees — several degrees below typical mid-June averages.

Communities from Green Bay and Appleton to Wausau, Marinette and Sturgeon Bay should expect repeated periods of rain and wet roadways. Locally heavier downpours may slow traffic along Interstate 41, U.S. Highway 10 and other major routes.

Thursday Through the Weekend

Rain chances ease Thursday to 30%–50%, though temperatures remain cool with highs of 67–75°F. Relief arrives Friday as temperatures rebound into the 83–87 degree range, though isolated storms remain possible through the weekend.

What You Should Do Now

Residents are urged to keep rain gear accessible, allow extra travel time Tuesday and Wednesday, and monitor local forecast updates closely. Additional weather advisories could be issued if rainfall becomes heavier or storms intensify.

Conditions are expected to shift quickly — staying informed could make all the difference this week.
