Wider weather episode

Remnants of a Mesoscale Convective System (MCS) shifted southeast across Southeast Oklahoma, Southwest Arkansas, and extreme Northeast Texas during the morning hours of July 29th, as a shortwave trough dropped southeast from Oklahoma into Arkansas and the Lower Mississippi Valley. While this complex of showers and embedded thunderstorms entered the region as non-severe, they gradually intensified as they moved across extreme Southern Arkansas and North Louisiana, in response to an unstable atmosphere that developed due to strong daytime heating as temperatures climbed to the mid and upper 90s. As a result, scattered severe thunderstorms producing damaging winds downed trees and power lines over extreme Southern Arkansas, before they spread southward across much of North Louisiana during the mid and late afternoon hours. These storms exited the area and weakened with the loss of heating once they moved into Central and Southern Louisiana.
