Category: Texas’s Weather
We've got a new severe thunderstorm watch that'll take us through most of the overnight hours. Officially this watch runs until 3 AM on Monday. It includes portions of the Hill Country, South-Central Texas, the Coastal Plains, and western portions of Southeast Texas. Uvalde, Kerrville, Pleasanton, San Antonio, San Marcos, Austin, Brenham, Victoria, Beeville, and Lake Jackson are included. This watch does NOT include Bryan, Conroe, Houston, or Corpus Christi. The Storm Prediction Center indicates the strongest thunderstorm may produce hurricane-force winds up to 75 MPH, very large hail up to the size of tennis balls, and perhaps a brief tornado. Isolated flash flooding will also be possible overnight. Not all storms will be severe and only the most intense may produce the aforementioned hazards.
Scattered thunderstorms are organizing in the southern Concho Valley, western Hill Country, and across portions of Central Texas. We'll be watching those storms out in the Concho Valley and Hill Country to potentially grow upscale into a cluster or squall line. If that growth occurs, we could see the threat for damaging straight-line winds increase across the Hill Country and South-Central Texas later this evening. That squall line would generally move east/southeast around 25 to 35 MPH. Large hail is also a threat, especially with these initial storms that are still more discrete and supercelluar.
Some of our high-resolution weather models do indicate that upscale growth occurring. Those models haven't done overly well with today's storms, so this will be more of a 'watch and wait' approach. If we do see a line or cluster organize this evening we could see those storms make their way southeast into the Coastal Plains and even portions of Southeast Texas overnight. Our concern regarding damaging winds and hail will decrease later tonight as storms get closer to the coast. However, we could continue to see gusty winds and heavy rainfall until storms move off the coast tomorrow morning. Flooding will be an elevated concern in the Brazos Valley and Southeast Texas due to heavier rains earlier today and with those storms just upstream in Central Texas. Those are only moving slowly to the south/southeast.
