Heavy Rain Back in the Forecast

posted by Jim Forsyth - 

Periods of locally heavy rain are expected  across South Central Texas today through the weekend and may lead to  flash or river flooding.

Area of Concern:

 All of South-Central Texas

Threats & Impacts: 

Rainfall:  2-4" totals possible today through Sunday with locally higher amounts 6-8"Several locations may experience minor flooding  with flood waters capable of causing small streams, creeks, canals, and  ditches to become swollen and overflow in a few places, but with little  to no property damage. Quick ponding of water  occurs at underpasses, low-lying spots, and poor drainage areas. Storm  drains and retention ponds become near-full and begin to overflow in a  few places. Flood waters may prompt brief road closures.

Timing and Overview:

Increasing moisture from the Gulf and  the Pacific combined with an upper level storm system moving across the  Southern Plains this weekend will generate periods of showers and  thunderstorms capable of locally heavy rain through the weekend.  Scattered showers and thunderstorms today and during the day Friday may  produce minor flooding issues from intense rain rates, but the best  potential for flash or river flooding will be Friday night into Saturday  as the upper level storm system drags a cold front across the region.  There is the potential that the cold front lifts back north into the  Coastal Plains on Sunday, allowing the heavy rain threat to persist  through the end of the weekend. A Flash Flood Watch may be needed at some point this weekend.
