434 FXUS64 KEWX 271824 CCA AFDEWX Area Forecast Discussion...CORRECTED National Weather Service Austin/San Antonio TX 124 PM CDT Fri Jun 27 2025 ...New SHORT TERM, LONG TERM, AVIATION... .Resended for corrected formatting .KEY MESSAGES... - Normal to slightly normal climate high temperatures expected for the weekend into next week. - Low chances for isolated showers and storms are forecasted for the coastal plains area this afternoon and Saturday. Increasing moisture associated to a tropical disturbance in the southwest part of the Gulf waters arrives Sunday and chances of rain spread to the I-35 corridor. - Light concentrations of Saharan dust arrives late Saturday into Sunday and increasing into early to mid next week, bringing hazy conditions to the Coastal Plains, I-35 corridor, and Hill Country. -Low chances for showers and storms persist across the coastal plains next week with high temperatures slightly higher than normal and back down to normal for Thursday before going back up Friday into next weekend. && .SHORT TERM... (Tonight through Saturday night) Issued at 1213 PM CDT Fri Jun 27 2025 Partly cloudy skies can be detected by visible satellite photos across the eastern two-thirds of South Central Texas early this afternoon. Area Doppler radars are showing light shower activity across the southern part of Lavaca County and a few thunderstorms to the south over Corpus Christi CWA. This activity could push to the north with the aid of the seabreeze during the next several hours to affect a greater portion of the coastal plains area but staying to the south of the I-35 corridor. Hires models suggest very isolated shower activity just to the south of the I-35 corridor between 3 pm and 6 pm. Therefore, expect dry conditions for most of the period with low probability of seeing a passing shower or storm for a short period of time. Otherwise, highs are expected to reach the lower to mid 90s over most places with upper 90s into 100 along the Rio Grande. Mostly clear to partly cloudy skies are forecasted for tonight into Saturday with overnight lows in the 70s. Clouds are likely to burn off by mid morning with mostly sunny to partly cloudy skies expected for the afternoon. Drier airmass should be in place and therefore, expect dry conditions for most places with a slight chance of a shower or two or a storm over Lavaca County or nearby locations. Saturday evening starts with a dry airmass, however, as the night progresses, increased moisture arrives across the coastal plains as a tropical disturbance over the southwest Gulf waters moves to the northwest over the Bay of Campeche. && .LONG TERM... (Sunday through Friday) Issued at 1213 PM CDT Fri Jun 27 2025 Chances of showers and thunderstorms are forecasted for areas along and south of the I-35 corridor on Sunday as increased tropical moisture arrives across the middle Texas coast and moves inland. By Sunday night, moisture pushes to the north and a dry and dusty airmass spreads across most of the local area associated with a Saharan Dust episode. Can`t rule out some hazy skies as early Saturday night into Sunday, but the better dust signal looks to be for Sunday into Monday and continues into mid week. Low chances for showers and storms are forecasted for early next week mainly across the coastal plains area and then over the Rio Grande on Wednesday and again over most areas on Thursday. A new wave of Saharan dust could arrive across the local area next Friday (fourth of July) into the weekend with a warming trend in store with highs reaching the 100 mark for several places from next Sunday and beyond. && .AVIATION... (18Z TAFS) Issued at 1213 PM CDT Fri Jun 27 2025 Outside of any isolated SHRA/TSRA activity this afternoon, VFR conditions through the afternoon and evening with a FEW-SCT cu field. Isolated SHRA/TSRA activity through sunset will be confined mainly east of the I-35 and I-37 corridors. BKN stratus is forecast to re-develop overnight along the I-35 corridor, expanding slightly east and west toward daybreak Saturday. This stratus will produce mainly MVFR ceilings and scatter out after 15Z Saturday. && .PRELIMINARY POINT TEMPS/POPS...
