Warm, moist, and unstable air surged north into East Texas, North Louisiana, and Southern Arkansas during the evening through the early morning hours of April 11th-12th, along a warm front that lifted north across much of East Texas into North Louisiana. Meanwhile, a strong upper level low opened up into a trough as it entered the Southern Plains during the evening of the 11th, with large scale forcing ahead of the trough enhancing shower and thunderstorm development across much of West-central, Central, East and Southeast Texas during the evening through the early morning hours. Given the extent of shear, instability, and upper level forcing in place across the warm sector, numerous showers and thunderstorms developed over these areas, which quickly spread east northeast into East Texas around and shortly after daybreak on the 12th, and into North Louisiana and Southern Arkansas during the mid and late morning hours. Some of these storms were severe, producing numerous reports of damaging winds and large hail.
While there was a lull in the thunderstorms from late morning through much of the afternoon, additional strong to severe thunderstorms developed across portions of Northeast Texas well behind the dry line which had mixed east to near Texarkana into Western Louisiana, and near the center of the upper level trough. Steep lapse rates aloft and the drier low level air mass contributed to areas of damaging winds and isolated instances of large hail. Aided by strong pressure rises behind an associated cold front, these scattered strong to severe thunderstorms that had developed along the front/dry line moved across portions of Southern Arkansas, before diminishing during the early evening hours as they tracked into portions of North Louisiana.
