The episode as NWS MAF wrote it up.
A mid level shortwave trough rotating around the periphery of an upper level ridge moved over the higher terrain of west Texas. The lift associated with this feature combined with fairly deep moisture and upslope flow to produce scattered thunderstorms across the region. Weak flow aloft resulted in slow moving, heavy rain producers over the Davis Mountains.
