599 FXUS64 KEWX 112331 AAA AFDEWX Area Forecast Discussion...UPDATED National Weather Service Austin/San Antonio TX 631 PM CDT Sat Oct 11 2025 ...New AVIATION... .KEY MESSAGES... - Low humidity, cooler mornings, and warm afternoons through the next week. && .SHORT TERM... (Tonight through Sunday night) Issued at 1256 PM CDT Sat Oct 11 2025 An upper level high continues to sit over West TX today. Surface high pressure is centered over Central TX making winds across our CWA light and variable. The airmass is drier again today with dewpoints 5-10 degrees lower than 24 hours ago. The upper ridge will continue to dominate during the short term keeping our weather dry. The surface high will drift toward east. Winds will remain light but become southeasterly tonight. With little change in the pattern temperatures will be about the same as the last day or two tonight through Sunday night. && .LONG TERM... (Monday through next Saturday) Issued at 1256 PM CDT Sat Oct 11 2025 The upper ridge will remain dominant through the middle of next week. This will keep all forcing to our west and north, so our weather will stay dry. Yesterday, both the GFS and ECMWF had an interesting inverted trough form over the eastern Gulf and move toward the west during the middle of the week. Today, both models develop a similar feature, but it is farther south. If this pans out any rain would be in Mexico. However, models develop a deep upper trough over Rockies and SW US which absorbs the southern wave and moves it across TX Friday. There is still not much lift with this feature and almost no chance for rain. Maybe only a glimmer of hope. Temperatures through the long term period will be fairly persistent varying only a degree or two day to day. Highs will be above normal and lows near normal. && .AVIATION... (00Z TAFS) Issued at 624 PM CDT Sat Oct 11 2025 VFR conditions are expected at area TAF sites through the current forecast period. Easterly winds along I-35 gradually shift to light and variable of light southerly overnight. South winds continue tomorrow, with gusty conditions likely after 18Z. Out west at DRT, gusty conditions linger for another hour or two, then subside as winds trend east-southeast. Gusty winds likely to re- develop at DRT tomorrow after 16Z. && .FIRE WEATHER... Issued at 1256 PM CDT Sat Oct 11 2025 Dry conditions over the next week along with low afternoon humidity, especially Sunday, will continue to promote the drying of fuels across the region. Despite relatively weak winds, elevated fire weather conditions are possible the next several days, especially along and east of the I-35 corridor where fuels are more drought stressed. && .PRELIMINARY POINT TEMPS/POPS...
