What happened

The episode as NWS LMK wrote it up.

Two rounds of severe weather moved through central Kentucky on August 4th. The first produced torrential rainfall in the Louisville Metro area with up to seven inches of rain falling in around two hours time. This created massive flash flooding issues across much of Jefferson County and caused millions of dollars in damage in Louisville. This area of rainfall also caused flooding issues in counties just south and east of Jefferson County as well. The heavy rain and thunderstorms also produced some hail and cloud to ground lightning that caused several fires, including one four-alarm apartment complex fire on the east side of Louisville. Several water rescues were performed as drivers became stranded during the first round of severe weather, which occurred during the morning rush hour.

Later in the afternoon, a line of severe thunderstorms moved into North-Central Kentucky producing damaging winds up to 75 mph along with another round of heavy rainfall which caused another round of flooding.

What forecasters said that day
