West Texas and southeast New Mexico were sitting under the east side of an upper ridge that extended from central Mexico to the Pacific Northwest.  At the surface, a trough extended from northeast New Mexico through Iowa and it was bringing a steady flow of moisture back across the region.  Good instability and steep lapse rates helped support storms with an upper level disturbance that moved through the northwest flow aloft.  Storms that developed produced some large hail, damaging winds, and flash flooding.
