A strong and occluded low pressure system moved through the state on Thursday, March the 18th. Deep moisture and steep lapse rates set the stage for convection during the afternoon. With freezing levels being very low, these storms were able to create copious amounts of hail in addition to torrential rainfall and excessive lightning. While only a few storms reached severe hail potential, a couple dozen others produced widespread small hail. Meanwhile, many of these storms began to train across the same locations, bringing multiple rounds of torrential rainfall. This then resulted in flash flooding during the late afternoon and evening hours. Light to moderate rainfall continued into the overnight hours, as wrap around moisture from the passing low took hold of eastern Kentucky.
