Green Bay, Wisconsin – Strong to severe thunderstorms could disrupt travel and evening plans across Wisconsin by mid-afternoon Friday, with damaging winds and flash flooding developing as early as 3 p.m.
According to the National Weather Service in Green Bay, storms will move west to east between 3 p.m. and 10 p.m., with the most intense activity expected from 4 p.m. to 8 p.m. across central Wisconsin. Areas near Wausau, Stevens Point, Marshfield, and Wisconsin Rapids sit in the highest risk zone, where wind gusts could exceed 70 mph and hail may reach 2 inches in diameter.
The threat shifts east into the Fox Valley and toward Green Bay between 6 p.m. and 10 p.m., though storms may weaken slightly as they approach Lake Michigan. A few tornadoes remain possible, especially where isolated storms can form ahead of the main line.
Heavy rainfall adds another layer of concern. Rain totals of 0.5 to 1 inch are likely statewide, with localized pockets reaching 2 inches, particularly near Stevens Point and Wausau. Saturated ground increases the risk of rapid runoff and flooding along rivers like the Wisconsin River and in urban areas.
Drivers should avoid flooded roads and monitor conditions closely during the evening commute. Have multiple ways to receive warnings, especially during the 4 p.m. to 8 p.m. peak window, as additional alerts may be issued through tonight.
