Overview

Two rounds of thunderstorms moved through the region on Thursday, July 21st. The first grazed northeast Illinois and northwest Indiana, bringing isolated gusty winds and locally heavy rainfall.  This also brought rain-cooled air into these areas, including downtown Chicago, which briefly brought relief from heat.  The second round of storms was far more widespread and moved southward through the area that evening.  Gusty winds and heavy rainfall were the main hazards, with reports of tree damage in isolated locations.
