Overview

Temperatures in the mid 80s and gulf moisture led to a very unstable atmosphere on Wednesday. An upper level wave and forcing ahead of a slow moving cold front initiated storms across the Midwest, including numerous severe storms across Northern Illinois and Northwest Indiana. The strongest storms produced 2-3" diameter  hail near Rockford, and a 67 MPH wind gust at Midway Airport, with significant wind damage near Midway. In addition, significant wind damage occurred in parts of northern Kankakee County and central Lake County Indiana.  After a brief break in storms, a line of storms brought large hail up to 2-2.5" diameter to northern Lake and McHenry Counties, and heavy rain to areas mainly north of I-80.
