Green Bay, Wisconsin – Drivers across northeast Wisconsin could face slick roads and sweltering heat by mid-afternoon Monday as storms sweep through the region.
According to the National Weather Service in Green Bay, a 20% chance of thunderstorms begins after 1 p.m. Monday, July 28th, paired with a dangerous heat index reaching 102°F. Actual highs will top out near 91°F, making this one of the hottest days of the summer so far. Winds from the south could gust up to 9 mph, increasing discomfort and storm development risk along U.S. Highway 41 and nearby county routes.
While storm chances remain isolated, any pop-up cells could bring brief downpours and lightning — a potential hazard for outdoor workers and drivers during the evening commute. Residents are urged to hydrate, avoid strenuous activity during peak heat, and keep an eye on local alerts if storms intensify later in the day.
Partly cloudy skies continue into Monday night with temperatures dropping to a low near 69°F. Another round of storms is possible Tuesday, especially before 1 p.m., with a 40% chance of showers and a high of 83°F. Winds will turn from the northeast and remain light, helping to bring slight relief from Monday’s heat.
