The episode as NWS SHV wrote it up.
A ridge of high pressure was located across the Tennessee Valley during the afternoon hours of September 11th. Weak perturbations aloft were moving from east to west under the ridge and provided the lift needed for widely scattered thunderstorms to develop during the afternoon hours. Storms produced strong wind gusts across Northeast Texas. Some of the storms also produced small hail in Gregg County, Texas.
