Low pressure tracking across north-central Illinois triggered widespread showers and thunderstorms during the evening of June 28th.  Some of the storms produced damaging wind gusts of 60 to 70 mph and hail as large as ping-pong balls.  One of the hardest hit areas was the town of Stewardson in Shelby County where a downburst with 80 to 90 mph winds created substantial wind damage.  In addition, thunderstorms with excessive rainfall rates created localized flash flooding across parts of central Illinois.
