GREEN BAY, Wis. – A mild stretch of fall weather will briefly return before another round of rain and cooler air moves into northeast Wisconsin by the weekend. Drivers and outdoor workers across Brown County should prepare for damp conditions and slower travel late Friday along I-41 and I-43.
According to the National Weather Service in Green Bay, Thursday will be the week’s best day for outdoor plans, featuring mostly sunny skies and highs around 63°F. By Friday morning, clouds will thicken ahead of a developing system bringing scattered showers through the afternoon and evening. Highs near 71°F will feel unusually warm for mid-October, but the mild air won’t last long.
Rain will become steadier Friday night, with gusty south winds near 20 mph and wet roads likely for football games and late commuters. Saturday will start damp, with lingering showers and falling temperatures. Outdoor events such as fall markets and pumpkin patches may need early rain gear, though gradual clearing is expected later in the day.
Sunday brings back that crisp fall feel — partly sunny with highs in the upper 50s — perfect for leaf-viewing drives or Halloween decorating. Residents should keep gutters clear and secure outdoor items before Friday’s gusts. Cooler air behind the system could bring the season’s first patchy frost to inland areas early next week.
