MN Weather: Cloudy Labor Day with Evening Storms Looming
Minnesota faces cloudy Labor Day conditions with highs near 80°F and muggy air before overnight thunderstorms hit western counties late Monday.
On Monday, September 7, 2026, Minnesotans celebrating Labor Day and attending the final day of the Minnesota State Fair faced warm, muggy conditions with temperatures climbing into the low 80s. Meteorologists warned that a cold front approaching from the west will bring scattered severe thunderstorms late Monday night across western Minnesota, stretching overnight into Tuesday morning.
Labor Day Forecast Brings Muggy Heat and Strong Wind Gusts
Twin Cities residents and holiday fairgoers experienced southerly wind gusts reaching up to 30 mph throughout the afternoon, pushing dew points into the sticky mid-60s. While daytime conditions remained predominantly dry for outdoor activities, high atmospheric moisture set the stage for an active evening transition.
“Much of the day will be dry, but scattered storms become more widespread late this evening and overnight as a cold front moves through.”

As the surface front advances into western Wisconsin by Tuesday morning, rainfall totals approaching an inch are expected across the metro area. FOX9 meteorologist Jonathan Yuhas highlighted that following early Tuesday showers, cooler northwest air will push into the region, dropping Wednesday high temperatures into the crisp low-to-mid 60s.
- Labor Day Highs: Peak temperatures reached the low 80s with southeast wind gusts up to 30 mph.
- Evening Storm Risk: Western Minnesota faces isolated severe storms post-10 p.m. with 50-70 mph wind threats.
