Overview

Scattered thunderstorms, some severe, developed ahead of a cold front that moved into a very warm and humid air mass across central and northeast Wisconsin. The strongest storms produced "wet microbursts" that resulted in winds over 75 mph and large hail.

Many dozens of trees were uprooted or snapped across the hardest hit areas. Six buildings sustained at least minor damage from fallen trees in the Mountain area of Oconto County.

Rainfall rates of over 2 inches per hour were reported with the strongest storms.
