269 FXUS64 KEWX 100006 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 606 PM CST Sun Nov 9 2025 ...New AVIATION... .KEY MESSAGES... - Windy conditions and near-critical to critical fire weather conditions to continue into the early evening - Light freezes expected around sunrise across portions of the Edwards Plateau and Hill Country on Monday, then low lying spots near the escarpment, I-35 corridor and Coastal Prairies Tuesday - Warm again mid week into next weekend - Elevated fire weather conditions for Coastal Prairies Monday, and elevated to near critical fire weather conditions over most of the South Central TX Tuesday && .SHORT TERM... (Today through Monday) Issued at 1152 AM CST Sun Nov 9 2025 Low end wind advisory conditions are occurring as of the late morning and midday. Upstream winds in Central TX might suggest the stronger winds to shift focus southward and relax a bit, leading to a possible early cancellation of the Wind Advisory in a few hours. The winds will remain plenty strong enough to warrant the Red Flag Warning. The next focus is for tonight`s low temperatures and the wind indications over the I-35 corridor would suggest not enough decoupling to allow for the first freeze in those areas. The first freeze and Freeze Warning product went out for the Hill Country and Edwards Plateau where better decoupling of wind and lower dew point temperatures are likely. Daytime Monday could start off a little breezy over the Coastal Prairies but the MOS guidance surface winds show decreases already by 18Z. Those waking up early will experience wind chills in the 20s across much of the area, but will see lighter winds and the max temperature recovering to the upper 50s to mid 60s. && .LONG TERM... (Monday night through Saturday) Issued at 1230 PM CST Sun Nov 9 2025 While the cold air advection is all but done by Monday evening, the cool starting temperatures, light winds, low dew points, and clear skies will all contribute to the coldest air of the season for the central, eastern, and southern counties. Another freeze warning is expected to go out for portions of these areas, but will not be confident on how far south and east to take the product in this package. Early Tuesday morning, winds over northwest counties will possibly curb the cooling early with higher terrain winds mixing the air leaving min temperatures that would occur a few hours before daybreak. These winds will continue to pick up as broad surface troughing deepen over the high plains into NW TX. The still very low dew points will aid in a rapid daytime warm-up back to above normal maxes and potentially some more fire weather concerns that could warrant a Fire Danger Statement. Dew points and humidity will recover more aggressively from the SE counties in the afternoon, but not until the evening over NW counties. Min temps for Wednesday morning will jump 10 to 20 degrees over those from Tuesday morning as a result. The warming trend continues through the work week before another polar trough brings the next weather change. Yesterday`s solutions suggested this would have been a favorable one with a weaker trough and some rain chances over much of the area. Today`s consensus depict a stronger and faster system, which might lead to less rain and more fire weather issues for next weekend. && .AVIATION... (00Z TAFS) Issued at 559 PM CST Sun Nov 9 2025 The only aviation issue this evening is the wind. Northerly winds will continue for the coming period in the Austin and San Antonio areas. Wind speeds have been decreasing and this will continue over the next few hours eventually dropping to 10-15 kts by around midnight. Wind speeds will be 10 kts or less Monday. At DRT winds have already dropped below 10 kts and will become light and variable overnight. By mid-morning Monday they will shift to southeast. && .FIRE WEATHER... Issued at 1052 AM CST Sun Nov 9 2025 A Red Flag Warning is in effect for all of South Central Texas for through 9 PM this evening. While little change in minimum humidities is expected on Monday, winds will be decreasing during the day. Morning to midday winds over the Coastal Prairies will remain high enough into the early afternoon for elevated to potentially near critical fire weather conditions. Southerly flow returns Tuesday with wind speeds picking up quickly over the higher terrain of the Edwards Plateau and Hill Country. Moisture will be slow to return in the daytime, so minimum humidities in the upper teens to 20s could lead to near critical to possibly critical fire weather conditions for some areas by Tuesday afternoon. Thus there are potentials for Fire Danger statements or Red Flag Warnings for Monday and Tuesday. Higher moisture levels will accompany breezy south winds Wednesday through Friday, but another disturbance could potentially bring another front and possible critical fire weather pattern next weekend. && .PRELIMINARY POINT TEMPS/POPS...
