370 FXUS64 KEWX 260534 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 1234 AM CDT Thu Jun 26 2025 ...New AVIATION... .SHORT TERM... (Tonight through Thursday night) Issued at 149 PM CDT Wed Jun 25 2025 Key Message: - Increasing shower and storm coverage into this evening mainly along and east of the I-35 Corridor. Troughing out in the Western U.S with monsoonal moisture continues while the eastern U.S sits beneath an expansive ridge of high pressure. This leaves us sandwiched between the two features thus giving us continued chances for daily showers and storms each afternoon. Looking at radar and visible satellite imagery we see that showers are already starting to pop for this afternoon. We expect these showers and thunderstorms to eventually increase in coverage with most activity expected to wane by sunset due to the loss of daytime heating. Tonight expect mostly cloudy skies with lighter winds with lows in the mid 70s. Tomorrow should be slightly drier, though chances of storms remain mainly in the Coastal Plains once again waning by sunset as the ridge creeps slowly westward and covers more of our area. As such temperatures are expected to be a touch warmer as well with highs in the low to mid 90s. Tomorrow night expect partly cloudy skies with lows once again in the mid 70s. && .LONG TERM... (Friday through Wednesday) Issued at 149 PM CDT Wed Jun 25 2025 Key Messages: - A warning trend is on the way for the weekend into next week - Saharan Air Layer arrives over the weekend and brings dry and dusty conditions across the local area to make hazy skies through the period Slow warming trend begins Friday into the weekend and continues into next week. Highs will range from the mid to upper 90s most areas with a few locations getting into the 100 to 101 along the Rio Grande over the weekend. By early next, highs are expected to increase a degree or two of those over the weekend and therefore more locations are likely to reach the 100 degree mark especially across the Austin area and vicinity. On top of the heat, a Saharan Air Layer is forecasted to affect most of South Central Texas starting on Saturday and continues into next week. Therefore, hazy skies are expected through the period as this dry and dusty airmass moves across the local area. Showers and thunderstorms will be limited to the coastal plains and areas east of Interstate 35 with the help of the afternoon sea breeze. Otherwise, dry weather conditions are expected for most periods. && .AVIATION...
