On Tuesday afternoon, August 6 2013, a supercell thunderstorm moved across central Minnesota into western Wisconsin and produced a long swath of severe weather. The storm moved across the heat of the Twin Cities while National Night Out activities were underway.

A supercell is a very strong thunderstorm that has a rotating updraft. They are able to sustain themselves for several hours, and produce large hail and damaging winds. The radar loop to the right shows the storm as it moved across the region. Numerous storm reports were received just south of the I-94 corridor. As the pictures below show, this storm caused extensive damage to crops and vehicles. Several storm spotters reported hail 2 inches or greater.
