A long-lived supercell thunderstorm continued its track from northeastern Wyoming, across the northern Black Hills, and into south central South Dakota. The storm left very large hail in its wake, especially from the Spearfish area to the north and east parts of Rapid City.  Wind gusts to 60 mph were also reported. Wind driven large hail produced significant vehicle and property damage in some areas. The storm finally weakened as it moved into Nebraska late in the evening.
