The episode as NWS RLX wrote it up.
In a hot and humid air, thunderstorms moved through southeast Ohio and mainly into West Virginia. However, one southern cluster did affect northeast Kentucky. Low level convergence was aided by a leftover boundary from early morning convection. The thunderstorms moved southeast around 25 mph. Wind gusts were the main hazard. The tall thunderstorms also produced considerable cloud to ground lightning.

NWS Charleston, WV wrote its last area forecast discussion before the first event at Aug 4, 1:55 PM EST, 1 hour 55 minutes earlier.
