An upper trough was off the Pacific coast and was moving inland over California and Arizona. This put West Texas and southeast New Mexico under southwest winds aloft. A dryline was backed up against the mountains leaving good moisture with 50 degree dewpoints off to the east. The dryline and boundaries across the area became the focus for thunderstorms. Lapse rates and instability were high, which aided in the development of severe storms with large hail, strong winds, and flash flooding.
