A strong closed upper low pressure system ejected northeast through the Oklahoma/Texas Panhandle region during the afternoon and evening hours of March 16th, which helped mix a dry line east across Oklahoma and Texas. Ahead of this dry line, a broad warm and moist sector spread north across the Ark-La-Tex, which allowed for greater instability to overspread into the area ahead of this surface feature. A complex of showers and thunderstorms developed over West Texas during the late afternoon through the evening hours on the 16th, before advancing east across the state during the overnight and early morning hours of the 17th. Some of these storms remained severe as they moved through East Texas around and shortly after daybreak, where damaging winds downed trees and power lines before gradually weakening as they moved into Western Louisiana.
