372 FXUS64 KEWX 171050 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 550 AM CDT Fri Oct 17 2025 ...New AVIATION... .KEY MESSAGES... - Unseasonably warm afternoons continue through early next week with mostly dry weather. - Slight chances of rain forecast for the Coastal Plains along the US Highway 77 corridor Friday and Saturday. && .SHORT TERM... (Today through Saturday) Issued at 1220 AM CDT Fri Oct 17 2025 Yet another cool and comfortable morning is expected to start the day Friday, with morning temperatures in the lower to middle 60s. Friday afternoon is shaping up to be yet another warm and dry day for most, outside of some potential showers developing over the Coastal Plains in the afternoon. Surface moisture will be on the increase in response to a trough over the Four Corners. Any rain that falls would be rather light and generally trivial in the grand scheme of things. Expect the trough mentioned above to approach the region Friday night into the start of the weekend, acting to at least bump up our humidity levels ahead of the approaching front expected to arrive early Sunday. A more mild and muggy night can be expected Friday night with the influx of moisture noted above. Some low end PoPs have been maintained for Saturday afternoon/evening ahead of the approaching cold front, but chances are less than 20% for all. && .LONG TERM... (Saturday night through Thursday) Issued at 1220 AM CDT Fri Oct 17 2025 On Sunday, with the passage of the Pacific front mentioned above, RH values will fall to between the upper teens to mid 20s for most, if not all of South Central Texas. Light east to northeast surface winds are forecast with portions of the Coastal Plains and I-35 Corridor showing speeds around 10 to 12 mph mid to late afternoon. Dry conditions, lack of recent rainfall, and some dry fuels would pose an elevated risk for wildfires over those locations. Mid-level ridging returns quickly on Monday and Tuesday, resulting in warm and dry days. Yet another dry cold frontal passage may occur on Tuesday afternoon, but considerable uncertainty in the medium range guidance beyond Monday makes it difficult to say. In any matter, mild and dry weather will continue for the foreseeable future... && .AVIATION... (12Z TAFS) Issued at 539 AM CDT Fri Oct 17 2025 MVFR cigs developed across the Rio Grande and portions of the southern Edwards Plateau a few hours ago. These low cigs are spreading to the north and east into the Hill Country and parts of the I-35 corridor including KSAT and KSSF. Low clouds are also forecast to affect KDRT within the next hour or by 11Z/12Z time frame. These low clouds lift mid morning with VFR anticipated for the rest of today and evening. Low clouds/MVFR cigs return tonight into Saturday morning. Can`t rule out IFR cigs for KSAT and KSSF by daybreak Saturday. A southeast wind flow of 5 to 10 knots is forecast for today with occasional higher gusts. && .PRELIMINARY POINT TEMPS/POPS...
