With a stationary boundary parked just north of the state, and deep S to SW flow, much of the state was seeing ample amounts of warm air and moisture being advected in. Afternoon storms developed each day, each capable of producing torrential rainfall. While the impacts were somewhat isolated on the 9th and 10th (Wednesday and Thursday), more scattered to widespread convection was forecast for Friday the 11th, leading to a Flash Flood Watch being issued through the day. Multiple flash flood reports were received this day, with the hardest hit area being Beattyville and Lee County, where considerable flash flooding was observed.
