The episode as NWS SHV wrote it up.
A deep upper level trough was nearly stationary across south central Texas with thunderstorms developing to the north and east of the trough during the morning hours of June 9th. The storms propagated into northeast Texas during the afternoon of the 9th and encountered a very unstable airmass. These storms become widespread across the region into the afternoon and evening hours of the 9th and produced large hail along with damaging thunderstorm wind gusts. Some of the storms were prolific rain producers with isolated reports of flash flooding. During the late evening hours of the 9th...storms began to redevelop closer to the trough of low pressure which was located just west and south of Tyler, Texas. These storms trained across the same general area and were prolific rainfall producers...especially across northeast Texas. Widespread flooding was common across portions of northeast Texas and this flooding continued into the day of the 10th.
