971 FXUS64 KEWX 212336 AAA AFDEWX Area Forecast Discussion...UPDATED National Weather Service Austin/San Antonio TX 536 PM CST Fri Nov 21 2025 ...New AVIATION... .KEY MESSAGES... - Maybe some showers across the south tonight and Saturday. - Another round of heavy rain is possible Sunday evening into Monday evening. The Southern Edwards Plateau, Hill Country, and I-35 Corridor to be impacted the most. - Fall like temperatures for Thanksgiving. && .SHORT TERM... (Tonight through Saturday night) Issued at 1135 AM CST Fri Nov 21 2025 West-southwesterly flow aloft is pushing a Pacific cold front through South-Central Texas. The front stretches from near Waco to Fredericksburg to Eagle Pass. There is cooler and drier air behind the front. The frontal zone lacks much lift, but there are a few showers in the vicinity. The front will continue its slow movement toward the southeast and then stall near our southern border. With warm, moist air south of the front there should be enough lift to generate isolated to scattered showers or thunderstorms tonight and Saturday across the southern part of our CWA. Say along and south of I-10/Hwy 90. Rainfall should be light to moderate. High pressure near the Arklatex region will send moisture up the Rio Grande during the day Saturday and isentropic lift may be sufficient to produce showers and thunderstorms starting over the southern Rio Grande Plains and spreading to the Southern Edwards Plateau. It`s not looking like any significant weather at this time. && .LONG TERM... (Sunday through next Friday) Issued at 1135 AM CST Fri Nov 21 2025 Sunday another Pacific cold front will move through West Texas. Southeasterly low level flow ahead of this boundary will bring high PW air back to our CWA. The front will move trough South- Central texas Sunday night/Monday. This will bring showers and thunderstorms along a line starting in the northwest Sunday and moving to the southeast exiting our area Monday night. This will produce mostly moderate rain, but there could be some locally heavy amounts with the high PW values we expect. WPC has issued a Marginal to Slight risk for excessive rainfall which could lead to flash flooding. Cooler, drier air will move in for the rest of the period. It may actually feel like fall for Thanksgiving. && .AVIATION... (00Z TAFS) Issued at 532 PM CST Fri Nov 21 2025 VFR conditions are forecast through the aviation cycle.
