763 FXUS64 KEWX 261913 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 213 PM CDT Sat Apr 26 2025 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Tonight through Sunday night) Issued at 128 PM CDT Sat Apr 26 2025 Key Message: - Isolated shower activity through late this afternoon. A weak shortwave moving over the area in tandem with daytime heating and sufficient moisture has generated some showers this afternoon with most activity over the coastal plains, I-35 corridor and eastern Hill Country. Don`t expect any significant rain amounts with this activity but some locations may pick up a couple hundredths to a tenth of an inch with more substantial showers. Upper ridging becomes more dominant over the area tomorrow which should further suppress showers. That said, a few thunderstorms may form along the dryline or mountains west of the area tomorrow and impact Val Verde County late Sunday. Otherwise, warm and humid conditions are expected for the weekend with highs in the 80s and 90s. Low cloud development is expected each night keeping mild low temperatures in place in the mid 60s to low 70s. Persistent southeasterly wind may be breezy in the afternoon and evenings. && .LONG TERM... (Monday through Saturday) Issued at 128 PM CDT Sat Apr 26 2025 Key messages: - Wet, warm, humid and stormy pattern resuming Monday next week. Monday should be the last quiet day weather wise for most with highs in the upper 80s to low 90s. Tuesday is where we resume our wet and stormy pattern as a low pressure and stationary front look to kick off showers and storms along it. Those storms should advance westward into our area by Tuesday night into Wednesday morning. We then get into a lull until either late Wednesday afternoon or early evening as a weak ridge over TX moves off to the east followed quickly by a trough. This trough and attendant cold front should give us enough forcing and lift for showers and storms to erupt over Central TX and progress southeast reaching the Southern Edwards Plateau and Hill Country first and reaching the rest of the forecast area late in the evening. Models still have some discrepancies with the Euro showing a pretty good convective system approaching while the GFS keeps it much further north out of our area. We will have to watch this for future forecasts as there certainly could be stronger storms with the added vorticity from the trough moving just to our north. Storms should continue moving southeastward into the coastal plains before we get a bit of a break for thursday depending on how the prior nights convection progresses. Thursday could end up even drier then forecast if we get overnight convection as the atmosphere will be overturned for most of the day. This is short lived however as the cold front that pushed through stalls just to our south for Friday into Saturday. Depending on where this now stationary front sets up could determine if we get yet another round of storms that ride along the front and across our area. Temperatures should remain in the upper 80s low 90s for highs and low 70s for lows throughout the period. Stay tuned for future forecasts as we get more clarity on these upcoming systems. && .AVIATION... (18Z TAFS) Issued at 1226 PM CDT Sat Apr 26 2025 MVFR ceilings may hold on another hour before VFR conditions return and remain through tonight. MVFR ceilings redevelop around 05-06Z for I- 35 sites and around 08Z for DRT. Higher probabilities for IFR ceilings are seen at AUS and SAT around sunrise. Southeasterly winds prevail with breezy/gusty conditions mainly daytime through evening hours. && .PRELIMINARY POINT TEMPS/POPS...
