Excessive Rainfall for Central Texas on Wednesday
Moderate to heavy rainfall is expected across central Texas again today. Moisture is moving northward behind a front. A trough to the west will provide lift, leading to the development of showers and thunderstorms. Rainfall amounts of 1-2 inches with locally higher amounts of 3 inches are expected. Given the previous rain and the saturated ground, flash flooding will be likely.

Risk for Excessive Rainfall across Central and Southeast Texas on Thursday
An area of low pressure has developed along the Texas coast and will serve as a focus for the development of showers and thunderstorms on Thursday.

Rainfall amounts will range 1-3 inches with locally higher amounts in excess of 4 inches, leading to a continued risk for flooding.
