Overview

On Friday, July 28th multiple rounds of thunderstorms moved through southern Wisconsin. Several surface boundaries provided sources of lift as the environment became more unstable. Initially supercells producing large hail around 2 inches in diameter and heavy rain impacted the area before a surging line of storms moved in from the northwest. 60 to 80 mph winds within the line resulted in tree damage across a large portion of the area.
