Hail in Upton County, Texas

A dryline would set up and become focused near the Texas/New Mexico state line south into the Lower Trans Pecos during the afternoon. At the same time, a southwestward advancing outflow boundary generated by a convective system east of the region would interact with the dryline. Initial thunderstorm development occurred near the Stockton Plateau and Llano Estecado. These thunderstorms would mainly produce instances of very large hail through the evening. A separate prolific severe weather-producing supercell would quickly develop at the intersection of the dryline and outflow boundary. This supercell would impact portions of Ector, Midland, and Upton Counties, producing several tornadoes, very large hail, damaging winds, and flash flooding.
