991 FXUS64 KEWX 081039 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 539 AM CDT Thu Oct 8 2026 ...New AVIATION... .KEY MESSAGES... Updated at 519 AM CDT Thu Oct 8 2026 - Dry weather continues through the weekend with near to slightly warmer than normal temperatures. - No significant rain chances through the weekend, but low end rain chances return to the area early next week with more humid conditions. && .SHORT TERM... (Today through Friday) Issued at 1200 AM CDT Thu Oct 8 2026 Cloud-free conditions and a light, mostly continental E/NE low level wind flow keep the RH values low and overnight minimum temperatures about 1-3 degrees below the seasonal norm. The afternoon sun and mostly subtropical ridging influences aloft will also take advantage of the arid regime with highs reaching about 4-7 degrees warmer than normal. This persistent and uneventful pattern continues through the short term, and goes a day or two into part of the long term portion of the forecast as well. && .LONG TERM... (Friday night through Wednesday) Issued at 1200 AM CDT Thu Oct 8 2026 After another full round of persistence weather Saturday, the pattern upstream of TX begins to push a weather change over our local area. Light winds and dry air will make for another pleasant evening for Saturday, but by Sunday morning the return of onshore winds will send the dew point and RH values upward. Model consensus has the winds blowing mostly SE Sunday, but the moisture loading will probably take a day before we get back into that sticky tropical heat. So while the impacts will begin Sunday, they may not be too noticeable until Monday with warmer min temps and higher heat index values in the afternoon. Unfortunately the consensus trends have a strengthening subtropical ridge over TX to slow the progress of the return flow and the developing upper troughing pattern over the Pacific. What looked like some opportunity for some streamer convection for next week by previous packages, the later model runs are coming in drier and drier. Thus it`s beginning to look like September all over again pattern-wise where the models project a trough to arrive about 9 days out only to push the pattern change backwards to delay the drought relief. Heat index values now look favorable to top 100 degrees over many areas for at least the first half of next week. && .AVIATION... (12Z TAFS) Issued at 519 AM CDT Thu Oct 8 2026 VFR conditions continue through the period under mostly clear skies.
