    Dangerous Complexes of Storms Prowl From Minnesota to Michigan

    Lives and property will be at risk across parts of the Upper Midwest, as clusters of severe thunderstorms roll along into Thursday night.

    One batch of fast-moving severe thunderstorms and blinding rain traveled from central Minnesota to northern Wisconsin and part of northern Michigan on Thursday.

    According to AccuWeather Severe Weather Expert Scott Breit, "The complex is capable of producing wind gusts to 70 mph and golf ball-sized hail."


    The northern tier storms can down trees, cause power outages and damage roofs and other structures.

    The strongest storms will likely remain north and east of Minneapolis.

    "The intense complex of storms will weaken as is moves across northern Lake Michigan Thursday afternoon," Breit said.

    However, locally heavy, gusty thunderstorms can still affect the upper part of the Lower Peninsula of Michigan Thursday afternoon.

    There is a chance the storms re-energize Thursday night around the Great Lakes region.

    According to AccuWeather Chief Meteorologist Elliot Abrams, "Storms occurring farther south at Thursday midday over Wisconsin, Illinois, northern Indiana and the southern part of Lower Michigan are much less intense, but can cause some travel disruptions as they move through.'

    The drenching storms will affect Chicago, Milwaukee, South Bend, Indiana, and Kalamazoo, Michigan.

    Downpours from any of the storms can produce isolated flash flooding.


    "The storms over the Upper Midwest at this time are associated with a surge of hot and humid air coming in for brief visit," Abrams said.

    The setup includes a strengthening disturbance that will track through the region Thursday. Much cooler air will sweep in at the end of the week and will end the threat of severe weather.

    This is the same system that was responsible for producing two funnel clouds in North Dakota on Wednesday, as well as several hail and wind reports across several states.

    A spotter in Waverly, Minnesota, reported hail 2-3 inches deep that destroyed a 25-acre apple orchard.

    Gusty winds were responsible for blowing over a semi truck on US-71 near Olivia, Minnesota.

    Outdoor activities may need to be put on hold or perhaps even cancelled if a widespread storm threat passes through. Always heed local weather warnings. Make sure to use the AccuWeather App to stay on top of severe weather.

    Other regions in the United States will be at risk for strong and flooding storms. Isolated storms are expected to fire along a cold front stretching across the Plains.

    Meanwhile, heavy, slow-moving showers and thunderstorms will present a flooding risk across the Southeast. Similar conditions occurred Wednesday when flooding rain hit Charlotte, North Carolina, forcing several water rescues.
