A Flood Watch has been issued which includes much of South Central Texas from 7 PM Wednesday through 7 PM Friday. A cold front will bring periods of heavy rainfall which could lead to life-threatening flash flooding. Stay weather aware and have multiple ways to receive warnings.
A slow moving cold front will bring multiple chances for heavy rain that could lead to flash flooding late today through Friday. Chances for heavy rain and flash flooding are highest Wednesday night into Friday. Widespread rainfall amounts of 2 to 4 inches with isolated higher amounts up to 8 inches are possible. Monitor trusted sources for forecast updates as we move through the work week.
Conditions will stay humid tonight as moisture moves in from the Pacific and the Gulf. A 30 to 50 percent chance of isolated showers and thunderstorms is possible over portions of the Southern Edwards Plateau after midnight. For the rest of South-Central Texas, expect skies to become cloudier. Breezy winds will continue throughout the night especially west of Interstate 35.
Above normal temperatures are expected through Wednesday. Rain chances increase Wednesday through Friday, with heavy rainfall possible. The passage of a Pacific cold front on Thursday will bring cooler temperatures for Friday into early next week.
The heavy rain this week could cause some flooding. Flooding can occur during any time of the year, so it’s always best to be prepared! To learn more about flooding and how you can prepare before it happens, visit weather.gov/safety/flood
