An area of low pressure and an assoicated cold front triggered widespread thunderstorms across central Illinois during the afternoon and evening of June 12th.  Many of the storms tapped into enhanced wind energy aloft and produced damaging wind gusts at the surface.  In addition, due to an extremely moist airmass in place across the region, locally heavy rainfall and flash flooding were common.
