820 FXUS64 KEWX 052358 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 658 PM CDT Tue Aug 5 2025 ...New AVIATION... .SHORT TERM... (Tonight through Wednesday night) Issued at 1200 PM CDT Tue Aug 5 2025 Looking at visible satellite imagery some fields of cumulus have popped up over the area mainly in the Coastal Plains in response to the afternoon seabreeze. Expect these clouds to continue to increase in coverage with daytime heating with maybe a shower or two across this area. Otherwise most areas should remain seasonably hot and dry. The main culprit for the next several days is a sub-tropical ridge located just to our west in New Mexico/El Paso TX area as noted on the 500mb heights analysis. Our area will be just on the southeast side of this ridge. This should keep us dry and seasonably hot through the short term and into the most of the long term forecast with the exception of the Coastal Plains where the daily seabreeze could generate some light showers and perhaps a storm or two. Highs for our area in the upper 90s to low 100s can be expected for tomorrow. with lows in the low to mid 70s. && .LONG TERM... (Thursday through Tuesday) Issued at 1200 PM CDT Tue Aug 5 2025 This ridge as alluded to in the short term is expected to strengthen through Friday as it meanders over the El Paso/New Mexico area before weakening and pushing its way westward by this weekend. Temperatures will remain seasonably hot with upper 90s to low 100s expected and mainly dry conditions continuing for Thursday and Friday. Saturday the ridge starts to move off to the west and weaken resulting in the chance of some showers and storms trying to make there way into the Coastal Plains and perhaps the I-35 Corridor. The only change is that temps will "cool" slightly a degree or two but dew points will be higher resulting in a hotter feels like temperature compared to the actual temperatures. This pattern looks to continue into early next week with temperatures moderating a bit as we continue with our summertime pattern. && .AVIATION... (00Z TAFS) Issued at 646 PM CDT Tue Aug 5 2025 Smoke from Canadian wildfires arriving from the north above FL090 may cause slight reductions in slant-range visibility through tomorrow, but near-surface impacts are not expected. Light easterly winds mostly near and below 10 kt will become weaker and variable tonight mainly after 08Z before a weak but more persistent southeasterly flow reestablishes after 15-16Z. Low chances for MVFR development at AUS/SAT/SSF after 08Z tonight, but cloud cover should remain sparse enough to maintain VFR through the TAF period. && .PRELIMINARY POINT TEMPS/POPS...
