The episode as NWS SHV wrote it up.
Severe thunderstorms developed across southeast Oklahoma and northeast Texas as a result of strong surface heating and a weak surface trough of low pressure. The storms in southeast Oklahoma were likely aided by the terrain of the Ouachita Mountains. The storms were very isolated in nature and produced large hail and damaging thunderstorm wind gusts.
