Overview

Fast Facts:

A line of storms traversed across northern Illinois and northwest Indiana between 3-8 pm CDT, with generally two more focused areas of wind.

The first was a line segment through the following counties:  Ogle, northern DeKalb, northern Kane, southern McHenry, far northern Cook, and southern Lake.  This produced concentrated significant wind damage in Huntley and adjacent areas.

A second one moved across far southern Lee County and along the far northern LaSalle County border.  This weakened slightly before entering the far southern Chicago metro, but still had 40+ mph wind gusts. Part of this area re-intensified in northwest Indiana across northern Lake and Porter Counties.
