A nearly stationary boundary was present over the western portions of the Low Rolling Plains and the eastern portions of the Texas Permian Basin this day. Surface convergence along this boundary combined with a mid-level shortwave trough moving over the area to create lift for showers and thunderstorms to develop.

The episode as NWS MAF wrote it up.
A nearly stationary boundary was present over the western portions of the Low Rolling Plains and the eastern portions of the Texas Permian Basin this day. Surface convergence along this boundary combined with a mid-level shortwave trough moving over the area to create lift for showers and thunderstorms to develop. Due to the plentiful moisture across the area and rainfall moving over the same areas, flash flooding was observed.
