A shortwave trough entered the Southern Plains during the morning hours of May 18th, and began to take on a negative tilt as it approached East Texas during the afternoon and evening. Meanwhile, an associated cold front began to shift southeast across Central Oklahoma and portions of North Texas, with the dry line having mixed east ahead of the front into Central Texas. Warm, moist, and unstable air surged north across the warm sector of Northern and Eastern Texas, Southeast Oklahoma, Southwest Arkansas, and North Louisiana, with large scale forcing spreading east across this area ahead of the trough such that numerous severe thunderstorms with damaging winds developed across East Texas. An isolated tornado also touched down just southeast of Tyler with one supercell thunderstorm. These storms began to move repeatedly over the same areas during the evening, with instances of flash flooding reported as well. These storms eventually spread into portions of North Louisiana during the early morning hours of the 19th.
