The episode as NWS LZK wrote it up.
The remnants of Tropical Storm Hermine passed to the west and north of Arkansas. As a result, tropical moisture was pulled up into Arkansas. A stationary front concentrated the heaviest rain across northern Arkansas. The tropical moisture lingered until it was swept out of the state by a cold front on the 11th.
