A severe thunderstorm rapidly strengthened during the early morning hours, producing hail up to the size of golf balls and damaging winds from 70 to 80 mph. During the mid-morning hours, a cluster of severe thunderstorms evolved into a thunderstorm complex that produced mainly damaging winds. The severe weather reports were concentrated mainly east of a line from Princeton to Evansville, including the eastern Evansville metro area. The persistence of the thunderstorm clusters over the same areas resulted in pockets of flash flooding. This morning round of severe thunderstorms was associated with a southwest wind flow of hot and humid air ahead of a cold front that extended from Wisconsin to northwest Missouri.
