Severe thunderstorms developed in far northeast South Dakota, and moved east-southeast across west-central, and into central and east-central Minnesota during the afternoon and evening hours of Tuesday, August 6th.
One of the storms was long-lived and produced a swath of very large hail from Morris, southeast to the Twin Cities Metro area aninto Wisconsin. Numerous vehicles and homes were damaged from golf ball, up to baseball size hail in the southern metropolitan area.  In Bloomington, hail smashed windows in the Wells Fargo Plaza, leaving broken glass in the 24-story building's entry ways. The storms also brought high winds, which knocked over large trees in areas across the Metro area. Xcel Energy reported over 70,000 customers from St. Cloud through the Twin Cities area were without power during the height of the storm.
