Flash Flood — Nicholas, Kentucky

2019-06-06 · near Henryville, Nicholas, Kentucky

Event narrative

State Road 32 was closed near Myers Station due to high water.

Wider weather episode

A moist and unstable air mass sat over the Ohio River Valley. CAPE values exceeded 3000 J/kg, but shear was weak. This provided an environment for pulse type thunderstorms. As the heat of the day began to build, it became enough to kickoff area thunderstorms. Thunderstorms across Kentucky caused several trees to fall, severe hail, and heavy rainfall which caused several locations to flood.

Over the flowing couple of days, moist air moved north from the Gulf of Mexico. Instability was enough to produce heavy rainfall, but not enough for widespread severe weather. Flooding was the result.
