The episode as NWS SHV wrote it up.
Very warm, moist, and unstable air was in place during the afternoon of Wednesday, April 1st, as an upper level trough of low pressure traversed east across Southeast Oklahoma, Western Arkansas, and East Texas. Increased large scale forcing within this unstable environment ahead of the trough resulted in the development of scattered strong to severe thunderstorms over portions of Northeast Texas, Southwest Arkansas, and North Central Louisiana during the mid-afternoon and evening hours, with several reports of trees being blown down across these areas. These storms weakened during the late evening with the loss of instability.
