The episode as NWS SHV wrote it up.
Scattered showers and thunderstorms developed during the late afternoon and early evening hours of July 26th across Eastern Oklahoma and Western Arkansas, as a result of two large clusters of thunderstorms and their associated outflow boundaries that affected these areas. These showers and thunderstorms became severe during the evening across McCurtain County, Oklahoma, resulting in several reports of downed trees near Hochatown and Broken Bow State Park. These storms also resulted in several gust fronts across McCurtain County as well as Sevier County, Arkansas, with wind gusts measured near 40 mph in Broken Bow, Oklahoma and DeQueen, Arkansas. These storms persisted during the overnight and early morning hours on the 27th, resulting in widespread 1-3 inches of rain across the severe and extreme drought stricken areas of Southeast Oklahoma and Southwest Arkansas, although no flooding was reported.
