547 FXUS64 KEWX 271150 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 550 AM CST Thu Nov 27 2025 ...New AVIATION... .KEY MESSAGES... - Cool and dry for Thanksgiving Day. - A wetter weather pattern may return Saturday and continue into next week. - Coldest temperatures of the season possible Sunday into next week && .SHORT TERM... (Tonight through Friday night) Issued at 1152 PM CST Wed Nov 26 2025 A broad upper level trough covers most of the country. The trough axis has moved to the east of Texas and the flow is from the northwest. At the surface, cooler, drier air has moved over South- Central Texas. Temperatures are 5-15 degrees cooler and dewpoints are 10-20 degrees lower than 24 hours ago. A low amplitude ridge will move over Texas today and then flatten tonight and Friday. Surface high pressure will move to the east turning the low level flow to the east. This will result in dry weather today and tonight. We expect seasonably cool high temperatures today in the 60s and lower 70s. The easterly winds will bring a slightly warmer airmass and lows Friday will be a little warmer than today. The easterly flow will also bring deeper moisture up the Rio Grande. A weak shortwave trough will move across the region Friday and produce chances for rain spreading from the Rio Grande area to the central part of our CWA through day Friday. && .LONG TERM... (Saturday through next Thursday) Issued at 1152 PM CST Wed Nov 26 2025 The next frontal system will move into the region Friday night and move away Saturday night. This will bring better chances for showers and possibly some thunderstorms to much of the CWA, although the better chances will be over the eastern half of the area where there will be deeper moisture. Breezy northerly winds will move in behind the cold front Saturday night and Sunday. This will bring another surge of cooler air. Highs Sunday will be in the 50s. The cool air will stick around for the last couple of days of the forecast. Lows Monday through Wednesday will be in the 30s and 40s with Tuesday looking like the coldest morning. We may need a Freeze Warning for much of the Hill Country, Edwards Plateau, and parts of the I-35 Corridor. Look for a warm up Wednesday and Thursday. && .AVIATION... (12Z TAFS) Issued at 541 AM CST Thu Nov 27 2025 VFR skies should last through the daytime across all TAF sites. In general, the TAFs are running a bit more aggressive on the basic MOS guidances, so the beginning of MVFR CIGs at DRT might be a tad early. Even the NBM comes in with MVFR skies before midnight which is also faster than the MET/MAV MOS timing. Winds will remain mainly below 10 knots as they slowly veer back toward return flow late in the periods. No rain is projected inside 30 hours, but there could be some in the daytime hours at DRT, or just beyond 24 hours. && .PRELIMINARY POINT TEMPS/POPS...
