Minneapolis, MN – Residents across Minnesota and western Wisconsin should prepare for a one-two punch of severe weather and extreme heat this week, starting with strong thunderstorms tonight. The primary threat shifts to a prolonged heatwave this weekend, with heat index values soaring above 100 degrees Fahrenheit for much of the region.
According to the National Weather Service Twin Cities, scattered strong to severe thunderstorms are possible late Thursday evening, particularly across western Minnesota. A more widespread threat for severe storms, including the potential for large hail, damaging winds, and a few tornadoes, is expected Friday afternoon and night, impacting central Minnesota and western Wisconsin.
Areas like Morris, Willmar, and Montevideo are under a slight risk for severe weather tonight. By Friday, the risk expands eastward, encompassing Brainerd, St. Cloud, Minneapolis, and St. Paul. Heavy localized rainfall could also lead to localized flooding, especially if multiple storms track over the same areas. Property owners should secure loose outdoor items and consider bringing pets indoors.
Following the storms, a significant heat risk arrives Saturday and Sunday. Daytime heat indices will exceed 100 degrees across most of Minnesota, including major cities like Madison, Mankato, and the Twin Cities. Even overnight, temperatures will struggle to cool, offering little relief. This level of heat affects everyone and can lead to heat-related illnesses without proper hydration or cooling. Ensure air conditioning units are functioning, or identify public cooling centers if needed.
Advisories for severe weather and excessive heat remain in effect through the weekend. Stay tuned for further updates and specific warnings from local authorities.
