An upper-level shortwave trough moved across a cold front over South-Central Texas and generated thunderstorms. The warm, moist airmass had steep mid-level lapse rates, and some of the storms produced large hail. There were also a few reports of damaging wind gusts and heavy rain that led to flash flooding.
