July 24, 2009: Morning Severe Weather in the East and South Twin Cities Metro
Synopsis | Storm Reports | Photos
A cluster of severe thunderstorms developed near the Twin Cities around 7 am on July 24th. They moved southeast during the rest of the morning, across the eastern metro area and other parts of southeast Minnesota, and a small part of west central Wisconsin. The storms developed in response to a rapid increase in instability and wind shear ahead of an eastward moving low pressure trough and cold front.
