Area Forecast Discussion National Weather Service Austin/San Antonio TX 247 AM CDT Tue Apr 29 2025 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Today through Wednesday) Issued at 155 AM CDT Tue Apr 29 2025 Key Message: - Marginal risks of strong to severe storms and excessive rainfall Val Verde County today and Hill Country to along and east of I-35 on Wednesday Widely scattered showers and isolated thunderstorms are noted over Mexico. These may cross the Rio Grande during the early morning hours and have slight chances in that area. Southerly lower level flow maintains a seasonably warm and humid airmass. Similar to the last couple of days, heating along the dryline in west Texas and the Serranias del Burro of northern Mexico will generate showers and thunderstorms this afternoon. Steering flow takes them over the Edwards Plateau and Rio Grande Plains this evening where they dissipate by around Midnight. As an upper level trough moves out over the Southern Plains, the dryline mixes to the east into the Edwards Plateau and Rio Grande on Wednesday to provide forcing. Showers and thunderstorms will develop over most areas, except the Rio Grande and western Edwards Plateau which will become drier in wake of the dryline passage. Steep mid level lapse rates, as well as, moderate to strong instability and deep layer shear suggest a potential of strong to severe storms. With the greater forcing northwest and north of our area, the threat is marginal. The favored areas for severe are Val Verde County today and the Hill Country to along and east of I-35 Wednesday. The main threats are large hail and damaging winds both days, however, a tornado or two may be possible across Central Texas on Wednesday. There is also a marginal risk of Excessive rainfall for the eastern Hill Country to along and east of I-35 Wednesday due to possibility of rains moving over the same areas. In wake of the dryline passage, minimum humidities in the single digits to lower 20s are expected across the Rio Grande into Edwards County with the lowest humidities across Val Verde County. Winds will be 5 to 10 mph across most of those areas, however 10 to 15 mph and gusty across northern portions of Val Verde and Edwards counties. This combination may result in elevated fire weather there. && .LONG TERM... (Wednesday night through Monday) Issued at 155 AM CDT Tue Apr 29 2025 Key Messages: -Severe weather possible Wednesday evening. -Strong storms and locally heavy rain may develop Friday night into Saturday, with near widespread rain coverage. -uncomfortable humidity and heat will be most felt on Thursday. The most aggressive storm activity will peak at around 00Z Thursday, with strong to severe storms remaining possible mainly east of Highway 281. Then rain chances fall off a cliff after 06Z Thursday. The Pacific front washes out quickly by 06Z and the dry-line advances back west again by daybreak Thursday. The westerly mid-level winds south of the northward lifting upper disturbance makes for a well capped afternoon, and the temps could get a little uncomfortable with many areas in the 90s with some heat indices potentially approaching 100. While the cap will probably hold through most of the afternoon, the shifting of winds by early evening may create enough lift for a few isolated strong to severe cells whether it comes from a sea- breeze, a weak front from the north, or terrain induced convection west of DRT. The GFS is most bullish for Thursday night, but isolated activity makes more sense with limitations to Pwat values. This problem is resolved better by mid afternoon Friday, as a more formidable frontal push arrives, and mid level winds turning more southerly brings a near removal of the dry capping layer. The front advances south steadily, but the flow aloft remains zonal, giving us the opportunity for multiple rounds of rain and storms through daytime Saturday. A shortwave ridge develops over TX to signal reduced rain chances for Saturday night into Sunday, but south low level winds develop again Sunday night. The moist layer deepens again, and another low latitude upper trough over the western CONUS sets up the region for another period of active storms early next week. && .AVIATION... (06Z TAFS) Issued at 1221 PM CDT Mon Apr 28 2025 Weakening SHRA over the Hill Country to the Rio Grande will dissipate during the next couple of hours with no impacts to the TAF sites. Some development of SHRA/TSRA is expected on Tuesday late afternoon into evening near the Rio Grande, however PROBs are currently too low to mention at KDRT. MVFR CIGs develop overnight into early morning, lift to VFR around midday, then return Tuesday night. Moderate S to SE winds will prevail. A few gusts up to 30 KTs or so are possible. && .PRELIMINARY POINT TEMPS/POPS...
