Minneapolis, Minnesota – A fast-building heat surge will push temperatures across Minnesota and Wisconsin 10 to 15 degrees above normal by Friday afternoon, bringing an early taste of summer and increasing the risk of evening thunderstorms.
According to the National Weather Service Climate Prediction Center, there is a 70 to 80 percent probability of above-normal temperatures across the Upper Midwest through early next week. Central Minnesota, including Minneapolis, and southern Wisconsin, including Madison and Milwaukee, are in a high-confidence zone for sustained warmth.
Minneapolis is expected to climb into the upper 70s to low 80s by Saturday between 2 p.m. and 6 p.m., with similar conditions extending east along I-94 into Wisconsin. Madison and Milwaukee will also reach the upper 70s to near 80 degrees, with dry and breezy conditions during peak heating hours.
By late afternoon into the evening, increasing moisture will trigger scattered showers and thunderstorms across both states. Storms may produce brief heavy rain, lightning, and wind gusts over 40 mph, especially along I-90 and I-94, potentially impacting travel.
Residents should stay hydrated, remain weather-aware during the evening commute, and prepare for rapid temperature swings. This pattern will persist through the weekend into early next week, with additional advisories likely as heat and storm chances continue.
