A very cold, arctic air mass continued to deepen as it shifted south across Southeast Oklahoma, Southwest Arkansas, Northeast Texas, and North Louisiana on February 14th-15th, ahead of a large upper trough that traversed east across the Southern Plains. Ahead of this trough, ample Pacific moisture was transported northeast across much of Texas, Oklahoma, Arkansas, and the northern half of Louisiana, as large scale forcing increased atop this very cold air mass. Meanwhile, an associated cold front was able to push south off the Southeast Texas and Southern Louisiana coasts, with overrunning of a milder, moist air mass atop the front that streamed north into Deep East Texas and North Louisiana. The combined forcing ahead of the trough and overrunning resulted in a large winter storm affecting across all of the Southern Plains and much of the Lower Mississippi Valley, where areas of heavy snow were observed across much of Central and North Texas, Oklahoma, and Arkansas. Farther south over South and East-Central Texas and North Louisiana, a mix of sleet, and freezing rain was observed, before the precipitation transitioned over to snow during the early morning hours of the 15th. Widespread snow and sleet amounts ranged from 5 to 10 inches across East and Northeast Texas, and from 3 to 6 inches across Deep East Texas.
