There was an upper ridge over the southwest part of the country with a cold front that moved into West Texas and southeast New Mexico during the late afternoon and evening hours.  A lot of heat and plentiful low-level moisture were across the area which aided in instability, and there was a surface low in the vicinity of the western Permian Basin. There was an upper level disturbance that moved over the area and intense low level winds that developed that evening and night which brought in more moisture. These conditions, along with good wind shear, allowed for thunderstorms to develop across West Texas and southeast New Mexico. These storms produced large hail, damaging winds, and flash flooding.
