A series of upper-level disturbances will move across Texas where there will be warm, moist air near the surface.
This will cause multiple rounds of showers and thunderstorms starting tonight and continuing through Thursday morning across South Central Texas.
The deep moisture will allow some storms to produce locally heavy rain that will lead to flash flooding.
