The episode as NWS SJT wrote it up.
A upper level low over New Mexico on the morning of the 11th moved to the east through the day. At the surface, cyclogenesis was taking place in south Texas with an inverted trough extending north of the surface low into West Central Texas. This combination resulted in the development of a line of strong to severe thunderstorms. An elevated supercell was embedded in the line as it tracked across Sterling and Coke Counties and produced mainly hail around an inch in diameter.
