The western edge of an upper ridge was over West Texas and an approaching upper trough was over the Rocky Mountains. Upper lift associated with the trough as well as upper disturbances moved over the area. High moisture was present across West Texas. These conditions, along with orographic lift along the Davis Mountains, resulted in thunderstorms that produced flash flooding and strong winds.
