Overview

During the late afternoon of Thursday, July 7th, scattered storms developed across northern Illinois and slowly moved east-northeast.  As the storms grew, their slow movement helped to produce locally heavy rainfall.  The Doppler Radar estimated rainfall maps show the localized nature of the heavy rainfall.  In addition, there were a handful of funnel cloud reports from the storms due to large scale rotation in the atmosphere.  Concentrated storm rotation for tornadoes was not favored.
