075 FXUS64 KEWX 281758 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 1158 AM CST Sat Feb 28 2026 ...New SHORT TERM, LONG TERM, AVIATION... .KEY MESSAGES... - Well above average temperatures continue through the next seven days. - Patchy to areas of fog possible across portions of the region during the next few mornings. - Low to medium chances (up to 60%) for rain and storms mid to late next week. && .SHORT TERM... (Tonight through Sunday night) Issued at 1154 AM CST Sat Feb 28 2026 A pattern of northwest flow aloft and southerly flow at low-levels continues this weekend, maintaining the pattern of unseasonably warm days and mild nights as we enter March. Dew points tonight are expected to rise as more Gulf moisture fluxes into the area, so lows are forecast to be more mild. Another round of morning fog is possible for mainly the Coastal Plains, I-35 corridor, and Hill Country with mist possible along the Balcones Escarpment, though modeled humidity profiles and slightly faster winds suggest slightly less favorability for fog compared to this morning. The added moisture should help take a few degrees off the highs for Sunday, but it'll still be a mostly sunny and warm day with highs in the 80s. A stronger low-level jet and a tighter pressure gradient courtesy of thermal low development over North Texas on Sunday will generate a steady southerly breeze with a few gusts up to the 25-30 mph range possible during the late afternoon. Rinse and repeat weather continues Sunday night with mild conditions and cloudiness continuing. && .LONG TERM... (Monday through next Saturday) Issued at 1154 AM CST Sat Feb 28 2026 The dry weather experienced across South-Central Texas over the past week was in large part due to a stationary ridge that has remained near Baja California since last Monday. There is good model agreement that the ridge will start to move east across Mexico and into the Gulf early next week, allowing winds aloft to gain a more westerly to southwesterly aspect more favorable to deeper moisture advection into our area. The low-level thermal ridge keeping our area warm likely won't budge much during the week, so confidence is high that unseasonably warm conditions will persist through the week. Breezy southerly winds should also continue each day, along with nocturnal gustiness on ridgetops. During the first half of the week, a trough will track across the Intermountain West and move into the Central Plains by about midweek. This is depicted across all model guidance, though the GFS/GEFS tend to project a faster and less impactful trough for our area than the majority of the models. The enhanced southwesterly flow aloft ahead of this disturbance should force an upward trend in temperatures Monday/Tuesday, but eventually a weak front associated with it may sag close to our area around Wednesday/Thursday. Modest forcing, shear, and weak to moderate instability should allow for some showers and possibly isolated thunderstorms around midweek. However, specifics on convective mode and shower coverage are still unclear given uncertainties with the front and trough positioning. Towards the end of the week, troughing over the western US is expected to deepen in response to ridge amplification over the northeastern Pacific. Broad mid- to upper-level height falls across the Southern Plains supports another favorable window of opportunity for rain opening next weekend. && .AVIATION... (18Z TAFS) Issued at 1154 AM CST Sat Feb 28 2026 MVFR conditions could last through the 18Z hour for KDRT. Otherwise, VFR conditions are forecast for all local terminals through late this evening. By midnight tonight or shortly after, low clouds are forecast to develop across the Coastal Plains and spreads to the north and northwest through mid Sunday morning. Patchy fog is also anticipated over some of these locations including the Austin and San Antonio airports. Confidence is low to medium as far as MVFR and IFR cigs making it to the I-35 corridor terminals and KDRT. There is low confidence on IFR vsbys for all terminals due to patchy fog. Southeast to south winds are forecast for this forecast cycle with speeds of 10 to 15 knots and higher gusts this afternoon and evening. A lighter southeast flow is forecast for tonight into Sunday morning. VFR conditions return for all area airports Sunday afternoon. && .PRELIMINARY POINT TEMPS/POPS...
