A longwave trough dug south into the Southern Plains during the daytime hours of October 20th, with southerly winds increasing ahead of the trough helping to return low level moisture north from the Gulf of Mexico. Above normal temperatures were seen across much of the region as readings climbed into the mid 80s to near 90 degrees, which enhanced instability during the late afternoon through the evening hours across much of the Ark-La-Tex area. While an isolated severe thunderstorm affected portions of East Texas and extreme Northwest Louisiana during the early and mid-evening hours, additional strong to severe thunderstorms developed during the late evening through the early morning hours on October 21st across Northeast Texas, Southeast Oklahoma, Southwest Arkansas, and North Louisiana ahead of this trough and associated strong cold front, as wind shear increased within a still unstable environment. These storms produced numerous reports of damaging winds across these areas, with an isolated tornado touching down in Southern Lafayette County before the storms diminished shortly after daybreak with the departure of this system.
