An upper level trough was centered over California and Nevada. A dryline was present across West Texas. High moisture and instability were present east of the dryline. High wind shear was also across the area. Upper level disturbances moved over the area which helped to increase atmospheric lift. These conditions resulted in thunderstorms with hail, strong winds, and flash flooding across West Texas.
