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 Northwest Louisiana during the morning hours of the 13th. While instability was very weak, the strong shear made up for the development of strong to severe thunderstorms. Training of storm echoes also occurred which resulted in widespread flash flooding across the region as well.
