430 FXUS64 KEWX 202343 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 643 PM CDT Fri Jun 20 2025 ...New AVIATION... .SHORT TERM... (Tonight through Saturday night) Issued at 104 PM CDT Fri Jun 20 2025 Key Message: - Low chances for isolated showers and storms today and Saturday. Mid-level high pressure will continue to shift east through the weekend, leaving South Central Texas on the western edge of this ridge. Weak disturbances along with high precipitable water values have allowed for isolated showers and a few thunderstorms to develop this morning and early afternoon, mainly over the coastal plains. Isolated activity may develop further west this afternoon. Gusty southeast wind continues in the west decreasing later this evening. Any showers or thunderstorms will also end early this evening with the loss of daytime heating. Mostly cloudy conditions with lows in the 70s are expected again tonight. Another day of isolated showers and thunderstorms is expected for Saturday, with models mainly focused over the western two-thirds of the area for these rain chances. Further east, PWATs lower on Saturday which could be contributed to some Saharan dust moving over eastern Texas. Expect slightly cooler temperatures in the west tomorrow as cloud cover lingers longest there. Highs may peak in the upper 80s over portions of the southern Edwards Plateau and Hill Country with the low to mid 90s elsewhere. && .LONG TERM... (Sunday through Friday) Issued at 104 PM CDT Fri Jun 20 2025 Key Messages: - Near normal highs with above normal low temperatures through the period. - Low rain chances continue next week, mainly over the coastal plains. A dominant ridge will remain over the eastern US next week with troughing over the western US. Sunday looks to be drier, but low precipitation chances quickly return to the forecast each day next week, mainly for the coastal plains eventually moving into the the I- 35 corridor mid to late week. This is mainly due to persistent southeasterly flow bringing in moist, Gulf air combined with daytime heating and possibly some weak mid-level disturbances. Highs will generally be in the low to mid 90s for the week except along the Rio Grande where the upper 90s to temperatures up to 102 degrees are forecast. Overnight lows will mainly be in the 70s. && .AVIATION... (00Z TAFS) Issued at 631 PM CDT Fri Jun 20 2025 VFR flight conditions with gusty southeasterly winds should continue for the next couple of hours before tapering off after sunset and into the overnight hours for all sites except KDRT. For KDRT Winds should decouple by 02Z before once again becoming gusty by 09Z. For I-35 sites expect a period of MVFR conditions overnight and returning to VFR by early morning with areas of SCT expected, much like we saw today. For KDRT MVFR conditions are forecast to clear up by late morning with gusty winds remaining throughout the afternoon. && .PRELIMINARY POINT TEMPS/POPS...
