A large upper level trough moved out of the Intermountain West and into the Southern Plains during the early morning hours of March 9th, taking on a negative tilt as it lifted east northeast across much of Central and Eastern Texas into Northern Louisiana and Southwest Arkansas. The trough allowed for a dry line to mix east across Central and Eastern Oklahoma, as well as Central Texas, into a region of moderate instability produced by a surge of very warm and moist air north from the Gulf of Mexico. As large scale forcing increased during the morning hours of the 9th, showers and thunderstorms, some of which were severe, developed and spread east northeast across Southeast Oklahoma, Southwest Arkansas, portions of Northeast Texas, and North Louisiana.  Damaging winds downed trees across portions of Northwest Louisiana, with NWS storm surveys confirming three tornado touchdowns across Northern Caddo, Bossier, and Webster Parishes before the storms weakened by early afternoon.
