Scattered showers and thunderstorms developed during the afternoon and evening hours across East Texas, Southern Arkansas, and much of North Louisiana, near a stationary front that extended from near the Red River of North Texas into Northeast Texas and North Louisiana. Moderate instability developed as afternoon temperatures climbed into the mid 90s, with abundant moisture in place with the passage of a weak upper level disturbance atop the front. Strong thunderstorms developed over Eastern Harrison County Texas which moved southeast and intensified across Southwest and southern Caddo Parish and across much of Red River Parish in Northwest Louisiana. This resulted in a wide swath of damaging winds of 60-70 mph across these areas, which downed numerous trees and power lines before weakening as they moved into Natchitoches Parish.
