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.

Environment
Clearing after the passage of a decaying thunderstorm complex Wednesday morning allowed for several hours of mostly sunny skies late morning into the early afternoon. Associated heating and a gradual increase of surface dew points from Gulf of America moisture allowed the the atmosphere to destabilize prior to the initialization of thunderstorms around 2pm. The cap on the environment, which initially suppressed storms, quickly eroded during the mid afternoon. This allowed storm coverage to increase as environmental shear gradually increased, setting up an environment conducive for severe convection across northern Illinois and northwest Indiana.
