GREEN BAY, Wis. – Northeast Wisconsin is gearing up for a damp and breezy weekend as a fall storm system brings showers and a few rumbles of thunder through Saturday night. The National Weather Service warns of locally heavy rainfall across the Fox Valley and lakeshore areas, including Green Bay, Appleton, and Manitowoc.
According to the NWS office in Green Bay, a weak front will spark scattered showers today, intensifying Saturday as a more organized system crosses the state. Thunderstorms are possible from midday Saturday into the evening, though severe weather is not expected. Drivers along I-43, Highway 41, and U.S. 141 should watch for ponding water and reduced visibility during heavier downpours.
Saturday will feel unseasonably warm before cooler air moves in. Highs will top out near 70°F before winds shift from the southwest to the northwest, ushering in drier air by Sunday. Gusts may reach 20 mph during the storm’s passage.
By Sunday, skies will clear, revealing a picture-perfect fall day across northeast Wisconsin. Highs will settle in the upper 50s, ideal for late-season yard work or fall park visits. Monday continues mild and bright before another round of light showers returns Monday night into Tuesday.
Residents are encouraged to secure outdoor decorations ahead of the gusty conditions and check local drainage to prevent minor flooding in low-lying areas. After a soggy Saturday, Sunday promises a calmer, classic October finish.
