An upper level trough over the southwestern US moved slowly toward the east causing heights to fall over Texas. A shortwave trough moved through this pattern and triggered thunderstorms across the western part of South Central Texas. Southeasterly low level flow ahead of this disturbance had increased precipitable water values to around 1.8 inches which was sufficient to produce locally heavy rain that led to flash flooding.
