Kentucky's Precipitation Record

The official 24-hour rainfall record for the state of Kentucky, 10.48 inches observed at Louisville (Jefferson County) on March 1, 1997, was the result of a powerful storm system. The combination of moisture from the Gulf of Mexico and a stationary front across the state produced heavy rains and thunderstorms until a cold front pushed all of the storms to the east and out of Kentucky.
