Thunderstorms rapidly developed around midnight on June 11th in central South Dakota, producing large hail up to 2.5 inches in size. As the storms moved to the east-northeast, they evolved into a line and produced a large area of wind damage across east central South Dakota.

The hardest hit areas were across Clark, Codington, Hamlin, and Deuel counties, where winds were estimated to reach 80 to 90 mph.  The storms continued east into Minnesota and eventually Wisconsin and Upper Michigan, producing damaging winds into the afternoon hours.
