Flash Flood — Hancock, Tennessee

Event narrative

Several road closures due to flooding.

Wider weather episode

A continuation of severe weather from the previous day involved convection which developed early in the day in association with an overnight outflow boundary followed by the main event involving a meso-scale convective system driving southeast into a moderately to highly unstable air mass. An amplifying upper level trough building east through the Ohio Valley added sufficient wind energy for strong and organized storm development. Late in the day into the evening, more storms developed ahead of the system cold front as it moved southeast toward the Southern Appalachian region.
