The worst of the damage was noted near the intersection of County Road 3170 and County Road 2376. Numerous trees were snapped and/or uprooted along the path of this tornado.

A strong upper level trough moved into the Central and Southern Plains during the morning and afternoon hours of December 12th. This trough ejected into the plains with a slight negative tilt which was indicative of strong jet dynamics in association with this trough. Likewise, low level and deep level shear was quite strong with this trough across Northeast Texas during the late afternoon and evening hours of the 12th as well as the morning hours of the 13th. While instability was very weak, the strong shear made up for the development of strong to severe thunderstorms, some of which produced tornadoes across Northeast Texas. Training of storm echoes also occurred which resulted in widespread flash flooding across the region as well.
