The episode as NWS SHV wrote it up.
A strong upper level trough moved out of the Four Corners region of the country and into the Central Plains during the early morning hours of February 10th. Strong southwest flow aloft was prevalent across the Southern Plains into the Lower Mississippi Valley as a warm front slowly lifted northward from the coast into East Texas and Central Louisiana. A line of thunderstorms developed along a prefrontal boundary west of the Interstate 35 corridor across Central and North Texas shortly after midnight on February 10th and this line of storms began racing eastward near 60 mph. Deep layer atmospheric shear which was mostly unidirectional which suggested that storm mode would be in the form of a squall line which did materialize and moved west to east across the region. Damage consisted of mostly trees and powerlines downed across a few locations.
