During the early morning of August 28, 2007, a mesoscale convective system (MCS) moved over the southern Twin Cities metro area and into western Wisconsin. This MCS was first associated with marginal severe hail, but soon transitioned to a damaging wind event from Redwood Falls, Minnesota to Cornell, Wisconsin. Wind gusts of 60-70 miles per hour were observed in Redwood County, Carver County, and the Twin Cities metro area.
