Clusters of thunderstorms drifted east-southeast across southwest Indiana. A hot and very moist air mass fed north-northeastward into these storms, maintaining a feed of instability. The storms produced torrential rainfall and an isolated microburst. The storms occurred along and ahead of a cold front that was draped across southern Illinois and southern Missouri.
