Strong southwest flow aloft across the Southern Plains and Lower Mississippi Valley resulted in a very warm and moderately unstable environment across this region during the late evening and overnight hours of January 12th continuing into the predawn hours of January 13th.  A strong cold front moved south and east...slowly across the region during the evening hours of the 12th and strong to severe thunderstorms developed across much of the region.  Due to the slow movement of the cold front...and the nearly unidirectional flow ahead of ahead of the boundary...these storms trained and produced locally heavy rainfall amounts which produced some flash flooding across the region.  In addition, strong deep layer shear resulted in some of the storms producing supercells with an isolated tornado noted across extreme Northwest Louisiana late on the 12th of January.
