591 FXUS64 KEWX 171823 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 123 PM CDT Thu Jul 17 2025 ...New SHORT TERM, LONG TERM, AVIATION... .KEY MESSAGES... - Low chance of isolated showers over the Coastal Plains Friday afternoon/evening. - Dry weather over the weekend into next week with elevated heat index values through the period && .SHORT TERM... (Tonight through Friday night) Issued at 119 PM CDT Thu Jul 17 2025 Quiet weather conditions are forecast for the rest of today into this evening and overnight periods. You may see scattered to broken upper level clouds moving from east to west associated with the tropical disturbance across the northern Gulf waters. By the way, the latest information about this disturbance (AL93) as of 1 PM CDT, shows a disorganized system with low chances for tropical cyclone formation in 48 hours. Tropical moisture is forecast to move along the Gulf coast and into the east and middle Texas coast by Friday. The combination of the seabreeze and this increased moisture could help isolated to scattered showers and thunderstorms to form over portions of the coastal plains. Other than that expect partly cloudy skies for the eastern two-thirds of South Central Texas with highs in the upper 80s to near 100. && .LONG TERM... (Saturday through Thursday) Issued at 119 PM CDT Thu Jul 17 2025 The weekend forecast calls for dry weather with humidity values increasing resulting in elevated heat index values in the 100 to 107 range with a few places getting into the 108 to 109. By Monday into Tuesday of next week, an upper level ridge takes control of the local area for plenty of dry weather conditions and the opportunity for a warming trend. && .AVIATION... (18Z TAFS) Issued at 119 PM CDT Thu Jul 17 2025 Few changes to the going forecast with VFR ceilings expected through the period. Expect winds to remain around 7-10 kts out of the south to southeast this afternoon before letting up somewhat this evening after sunset. There is a low chance, about 20-40% per SREF guidance that MVFR ceilings could develop at SAT, SSF, and AUS, particularly SSF, but will opt for VFR ceilings for now. Winds shift to more southeasterly by midday Friday at all sites. && .PRELIMINARY POINT TEMPS/POPS...
