The episode as NWS RLX wrote it up.
Several upper level shortwave troughs moved across the middle Ohio River Valley and Central Appalachians on the 21st and 22nd. The afternoons were hot and humid during this time, so the shortwaves that crossed during the afternoon kicked off showers and thunderstorms. The stronger storms produced isolated wind damage.
