641 FXUS64 KEWX 082343 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 543 PM CST Sat Nov 8 2025 ...New AVIATION... .KEY MESSAGES... - Very warm today, though just short of record highs - Strong cold front tonight brings breezy to windy conditions, much cooler temperatures, and near-critical to critical fire weather conditions - Light freezes possible Monday and Tuesday across portions of the Edwards Plateau, Hill Country, and low lying spots along the I-35 and US 90 Escarpment && .SHORT TERM... (Tonight through Sunday night) Issued at 1219 PM CST Sat Nov 8 2025 Cold front is still up in NW TX, but the polar jet will be diving south across the Central Plains today and that will push the front quickly into South Central TX late tonight. As with most November cold fronts, the first several hours is mostly a well mixed layer with temperatures gradually dropping and being offset by daytime heating. Gusty winds to 35 mph should be mostly below wind advisory criteria, but a few winds along the escarpment might gust to 40 mph before daybreak. We opted to start the Wind Advisory at 3 AM, but the majority of the sustained winds over 25 mph are expected once the sun comes up and daytime mixing ensues. Fire weather concerns increase after daybreak, and the gustiness of winds could last into the early evening hours. The winds don`t fully decouple Sunday night so we feel pretty good above most of the I-35 areas to remain above freezing for Sunday night. However, we could see parts of the Hill Country and areas north of Austin with a need for a Freeze Warning to announce the first freeze of the cool season. && .LONG TERM... (Monday through next Saturday) Issued at 1219 PM CST Sat Nov 8 2025 Monday will see some moderate and occasionally gusty winds over the Coastal Prairies, but winds should trend lighter late in the day and be well decoupled for another potential freeze night, but this time mainly east of the escarpment and potentially around Hondo. Higher terrain areas of the Hill Country should see the southerly winds already returning as surface troughing amplifies into NW TX. A relatively breezy period of southerly winds resumes mid-week into Saturday with a ridge dominated but progressive polar flow pattern aloft. This returns the warming trend quickly with a quick jump back to above normal highs expected Wednesday. Gulf moisture levels improve gradually late next week, and by next Saturday, some low rain chances could take shape as upper troughing approaches West TX. && .AVIATION... (00Z TAFS) Issued at 543 PM CST Sat Nov 8 2025 VFR flying conditions are expected tonight through Sunday night with only FEW080 late tonight into Sunday possible. VRBL winds of less than 5 KTs will become northerly as a cold front approaches, then increase to 10 to 20 KTs with a few gusts to 30 KTs with its passage overnight. Speeds of 15 to 25 KTs with a few gusts to 35 KTs are expected on Sunday mainly at the I-35 sites. Speeds will decrease Sunday night, though remain elevated. && .FIRE WEATHER... Issued at 1219 PM CST Sat Nov 8 2025 Red Flag Warning upgrade was sent for Sunday. Weather trends continue to look on track for near widespread critical fire conditions between 9 AM and 9 PM. Dry conditions will last through Tuesday, so Monday`s residual 10-15 mph north winds over the Coastal Prairies could be elevated for few hours. On Tuesday, south winds return with some afternoon gusts to 25 mph possible especially for the Hill Country. Any trend changes on these two days could lead to additional Fire Danger Statements of possibly Red Flag Warnings. Humidity values recover by Wednesday while winds remain southerly through the work week. && .PRELIMINARY POINT TEMPS/POPS...
