What happened

The episode as NWS PAH wrote it up.

Thunderstorms produced up to 2.5 inches of rain in an hour. At the Paducah National Weather Service office, over 1.5 inches of rain fell in less than one hour. The heaviest rain, around 2 inches per hour, fell in a narrow swath from southeast Ballard County through western and northern McCracken County and eastern Massac County to northern Livingston County. This resulted in flash flooding of a few roads and low-lying areas.
