736 FXUS64 KEWX 301122 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 622 AM CDT Mon Jun 30 2025 ...New AVIATION... .KEY MESSAGES... - Temperatures trend slightly below average this week, then slightly above average next weekend. - Low chances of showers and thunderstorms trend westward by mid week with locally heavy downpours and gusty winds possible. - Light concentrations of Saharan dust aloft with no impact on surface visibilities. && .SHORT TERM... (Today through Tuesday) Issued at 105 AM CDT Mon Jun 30 2025 The Subtropical Ridge remains over eastern Texas while upper level troughing takes shape over northern Mexico into Western Texas today. This maintains deep moisture over most of our area continuing our low chances of showers and thunderstorms. The Ridge builds a little to the west over eastern parts of our area on Tuesday. This brings a drier and somewhat subsident airmass along with some Saharan dust. This causes the low chances of showers and thunderstorms to continue out west while wane over the eastern areas. With PWs nearing 2 inches, cannot rule out locally heavy downpours. Gusty winds are possible as the storms collapse. While skies overhead may become hazy due to the dust aloft, surface visibilities will not be impacted. Near average temperatures continue in the east while "cooling" to below average out west due to increased moisture and rain. && .LONG TERM... (Tuesday night through Sunday) Issued at 105 AM CDT Mon Jun 30 20254 The Subtropical Ridge remains centered to our east with upper level troughing over Mexico into western Texas mid into late week. Deep moisture is focused out west with a drier and subsident airmass in the east. As a result, the higher rain chances are out west. Locally heavy downpours and gusty winds are possible out west. A potential for nighttime warm rain processes could also develop out west should more tropical moisture be drawn over that area. Below average high temperatures continue out west due to the increased clouds and rain with near average high temperatures across eastern areas closer to the Subtropical Ridge. The Ridge builds over our area as most of the trough lifts over the top of the Ridge while the remainder fills next weekend. Moisture decreases, subsidence increases, and another surge of Sahara dust lead to rain chances waning. Temperatures warm to near to slightly above average next weekend. && .AVIATION... (12Z TAFS) Issued at 621 AM CDT Mon Jun 30 2025 Patchy MVFR ceilings will continue through 15-16Z at terminals before VFR conditions return to all of South Central Texas. A plume of Saharan dust moves over the eastern half of the area today which could bring periods of HZ, though visibility is unlikely to fall below 6SM. Models have been consistent bringing showers and thunderstorms north into the area this afternoon and have included TEMPO groups at SAT/SSF for the best timing. There remains lesser confidence for activity at DRT and AUS. && .PRELIMINARY POINT TEMPS/POPS...
