The episode as NWS SHV wrote it up.
Numerous showers and thunderstorms developed shortly after daybreak on Saturday, August 9th across eastern McCurtain County Oklahoma and the northern sections of Southwest Arkansas, along a stationary outflow boundary from earlier storms that developed the previous day over central and eastern Oklahoma, as well as western Arkansas. Additional redevelopment occurred through much of the morning, with these storms moving repeatedly over the same areas. Widespread 2 to 4 inch rainfall totals, with isolated amounts exceeding 5 inches, fell over much of Sevier, Howard, and northern Hempstead counties within a matter of a few hours, resulting in numerous reports of flash flooding throughout Sevier County.
After these storms diminished during the early afternoon, other scattered showers and thunderstorms developed farther south along various outflow boundaries during peak heating and instability. One of these storms became severe, which produced a localized downburst over Claiborne Parish in North Louisiana.
