(Tonight through Monday night) Issued at 1249 PM CDT Sun Oct 12 2025 The center of an upper level high has drifted to northern Mexico today. Surface high pressure is centered over southwestern LA making winds across our CWA southeasterly. We are starting to see a little moisture return over the eastern counties. The upper ridge will continue to dominate during the short term keeping our weather dry. The low level flow will remain southeasterly and dewpoints will increase. Low temperatures tonight will be 2-3 degrees warmer than Saturday night and then be about the same Tuesday morning. Highs Monday will be nearly the same as today. && .LONG TERM... (Tuesday through next Sunday) Issued at 1249 PM CDT Sun Oct 12 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. The latter part of the week a deep upper trough will move across the Rockies into the Plains. Down here the flow will become westerly. While this change the wind direction aloft, it won`t provide any lift to produce rain. 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. Saturday the tail end of the upper trough will move across TX and bring a cold front across our CWA. There may be enough lift and moisture over our eastern counties to generate showers and thunderstorms Saturday night and early Sunday. && .AVIATION... (00Z TAFS) Issued at 639 PM CDT Sun Oct 12 2025 VFR conditions continue this evening as wind gusts are expected to ease through sunset. Some high clouds move in from the west, with the clouds remaining thicker out west near the Rio Grande. Model soundings still favor the development of MVFR clouds Monday morning, with the higher coverage of low clouds remaining near DRT. We will continue to mention prevailing MVFR conditions at DRT, SAT and SSF, with a TEMPO group at AUS. Will monitor 00Z soundings and the latest forecasts to see if we need to scale back to TEMPO groups at SAT and SSF instead of prevailing. && .PRELIMINARY POINT TEMPS/POPS...
