A deep upper trough exited the Inter-Mountain West and moved into the Southern Plains on the 17th of November. Ahead of this trough, copious amounts of moisture streamed northward from the Eastern Pacific and Gulf of Mexico. A warm front also lifted northward form the Gulf Coast, through Northeast Texas, Northwest Louisiana and Southern Arkansas. The atmosphere became weakly unstable across the region after sunrise on the 17th but atmospheric wind shear was very strong, both in the lower levels and the mid and upper levels of the atmosphere. As a result, storms took on bowing line segments with a few discrete storms also present during the day. These storms produced widespread wind damage and some flash flooding from excessive heavy rainfall with thunderstorm training occurred.
