The following forecast update is for portions of the southern Edwards Plateau region, South Central Texas and Southeast Texas for late this evening through the overnight hours. The Storm Prediction Center has a good portion of south central and southeast Texas under an Enhanced Risk for severe weather development later this evening and overnight. A few cities included in the Enhanced Risk area are Austin, San Antonio, Bryan/College Station, Corpus Christi, Victoria, Hallettsville and the Houston/Galveston metro area. If you live in the Enhanced Risk area, it’s advised that you monitor the weather overnight and have your weather radio on!
While this area has experienced a bit of a lull after early morning convection, additional widespread rain and thunderstorms are expected to develop later this evening and overnight across southern and south central Texas as additional lift arrives from the approaching upper level low. Even during the overnight hours, instability values are expected to hover around moderate levels which will lead to widespread storm development, eventually evolving into a squall line of storms which will push across south central Texas late tonight and into southeastern Texas during the early morning morning hours. A few tornadoes are also possible, one or two possibly strong. Other threats with storms overnight will be damaging winds, large hail and heavy rain which will tend to train over the same locations increasing the chance for flash flooding. The areas of heaviest rainfall are expected to remain primarily east of the US-77 corridor with widespread 2 to 4 inch amounts, with pockets of accumulations greater than 5 inches. We will be keeping an eye on these threats overnight and will update you as things develop, so be sure to check back!
