445 FXUS64 KEWX 121030 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 530 AM CDT Sun Oct 12 2025 ...New AVIATION... .KEY MESSAGES... - Low humidity, cooler mornings, and warm afternoons through the next week. && .SHORT TERM... (Today through Monday) Issued at 1250 AM CDT Sun Oct 12 2025 Upper level high pressure over West TX continues to influence our area while the surface high is located along the Texas/Louisiana border. Recent dewpoint observations show dewpoints already in the 40s. This should remain short lived as winds briefly switch out of the southeast bringing a slight uptick in moisture (upper 50s to lower 60s). Though moisture increases we should still see another cool morning with lows upper 50s north to lower 60s south and highs once again in the lower 90s. Expect a near repeat for Monday`s forecast as we continue to remain influenced by this high. && .LONG TERM... (Monday night through Saturday) Issued at 1250 AM CDT Sun Oct 12 2025 The upper level ridge aloft strengthens Tuesday and Wednesday, centering over or just east of our area. Global models continue to remain in great agreement indicating this high shunting all disturbances to our north and west keeping us dry. Well above normal high temperatures should continue next week with highs expected to approach and exceed 90 degrees. There are signals by some of the Global models (GFS and Euro) that we could be in for a pattern change just outside this forecast period with even a decent shot of rain (maybe?). However, for now our pattern of warmer afternoon highs and cooler mornings looks to continue through the work week. && .AVIATION...
