Area Forecast Discussion...UPDATED National Weather Service Austin/San Antonio TX 834 PM CDT Tue May 10 2022 ...New MESOSCALE UPDATE... .MESOSCALE UPDATE FOR SEVERE THUNDERSTORMS... Issued at 830 PM CDT Tue May 10 2022 Severe thunderstorms that developed earlier across Val Verde County have evolved into a broken convective line now into Kinney and Edwards counties. This has necessitated the expansion of the Severe Thunderstorm Watch into these counties. The line could make it into portions of Real and western Uvalde counties. However, increasing convective inhibition farther east could eventually result in a weakening trend 10 PM to midnight. && .MESOSCALE UPDATE FOR SEVERE THUNDERSTORMS... Issued at 413 PM CDT Tue May 10 2022 A Severe Thunderstorm Watch has been issued for Val Verde County through 11 PM CDT. Some storms will be capable of producing large hail and damaging wind gusts this evening across this area. Some of the convective allowing models indicate the discrete storms across Mexico and the dry line evolving into one or more convective lines into the early evening. The convective allowing models indicate southern storms and severe threat rapidly weakening 10 PM to Midnight across the western 1/3 of the CWA. && .SHORT TERM... (Tonight through Wednesday night) Issued at 128 PM CDT Tue May 10 2022 A strong cap is reducing diurnal heating and keeping convection from developing over most of the area. There are a few, elevated, stray sprinkles along and east of I-35, but those are rooted above the boundary layer and hence moisture-starved, so we do not expect them to develop more than they already have. The bigger show will be late this afternoon and evening as a weak shortwave trough, the dryline, and several mountain chains in west Texas and northern Mexico initiate convection. CAPE, bulk shear, and SRH are all sufficient for supercells, but the profiles seem to indicate these will be LP "barber pole" supercells (mostly in West Texas), or the cold pools will grow upscale into short lines of storms. The upshot for our area are good chances for rain on the Rio Grande Plains, but only light to moderate amounts, and lower end severe threats of large hail and damaging winds. One or two storms may make it to the U.S. Highway 83 corridor, but these would not be severe, nor bring significant rainfall. Otherwise, the longwave pattern begins to transition on Wednesday toward zonal at mid and upper levels. With no near-surface boundaries in the area, we do not anticipate any thunderstorms. Conditions will be more similar to mid to late summer, with cloudy skies and muggy conditions in the mornings, followed by partly cloudy and hot afternoons. Temperatures will be above normal, but should not threaten records. && .LONG TERM... (Thursday through Monday) Issued at 128 PM CDT Tue May 10 2022 High pressure under upper level ridging will dominate through the long term period. The surface high over the Gulf will keep the dryline and any convection west of our CWA most days. The only chance for showers and thunderstorms over us will be Friday afternoon when a weak shortwave trough moves across Texas. The only part of the area that will have any chance for rain will be northern Val Verde County, and even there chances will be very low. The rest of the area will remain dry. Temperatures through the end of the week will continue well above normal with highs mainly in the middle to upper 90s. Sunday and Monday the upper ridge will strengthen over Texas and increased subsidence will push temperatures a bit higher with triple digit highs over much of the CWA Monday. && .AVIATION... (00Z TAFS) Issued at 617 PM CDT Tue May 10 2022 Convection has developed in the higher terrain of Mexico and is now crossing the Rio Grande, north of DRT. Several models indicate coverage increasing in the vicinity of Del Rio 01Z-03Z. Some of the storms could become severe, producing large hail and wind gusts in excess of 50KT. Models indicate the southern end of the activity weakening around 04Z-06Z. We do not expect this to reach the I-35 corridor sites. Otherwise, VFR conditions prevail this evening, outside of convection. Stratus is expected to re-develop from the Coastal Plains into the I-35 corridor between 04Z-07Z and the west through the Hill Country overnight and into the Rio Grande 08Z-12Z Tuesday. Stratus will again mix out between 15Z-18Z Tuesday. Haze also continues to linger across South Central Texas, partially owing to smoke particulate that has been advected into the region from seasonal agricultural burns taking place in Mexico. While visibility with the haze is mostly greater than 6SM, there have been some periods the past couple of days where visibility briefly drops into the MVFR range. This has been mostly occurring in the morning hours. South to southeast winds will continue through the TAF period, with some gusts between 20-28KT this evening and again Wednesday afternoon and evening. && .PRELIMINARY POINT TEMPS/POPS...
