A southern stream trough approached the region from the west.  Increasing low level moisture, strong upper level lift, instability, and wind shear ahead of the trough supported the development of thunderstorms with large hail across West Texas.  The high moisture content of the atmosphere and slow storm motion resulted in heavy rain and flash flooding.
