534 FXUS64 KEWX 231749 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 1249 PM CDT Sat Aug 23 2025 .KEY MESSAGES... - Daily chances of showers and thunderstorms through next week - Locally heavy rains and gusty winds possible through this evening then again Tuesday and Wednesday && .SHORT TERM (THROUGH SUNDAY NIGHT)... Daytime heating and modest precipitable water values will keep rain chances in the forecast today with the best chances generally south of I-10 where moisture remains highest. Coverage should be widely isolated today with any activity that does pop up, so just know the majority of the area will miss out on rain. Some heavy downpours and gusty wind would still be possible with any activity. Drier air moves into the region tonight and Sunday suppressing rain chances even more for tomorrow. So to sum it up, a mostly dry and seasonably hot weekend is expected. && .LONG TERM (MONDAY THROUGH SATURDAY)... A relative lull in rain chances is expected Monday as the subtropical ridge continues its expansion eastward over the area where it will remain through much of the week. Winds return to southeasterly bringing increased moisture back to the area during the day Monday bringing low precipitation chances over the southern reaches of the CWA Monday afternoon, though the vast majority will see dry conditions this day. A front drops into Texas Tuesday and Wednesday before lifting back north late week. Moisture convergence along this frontal zone will bring back medium rain chances to the area Tuesday through Wednesday, including the overnight hours. Given weak flow aloft and a the presence of a boundary, any storms could be slow moving bringing the potential for locally heavy rainfall back into our area. Rain chances decrease but remain present Thursday and Friday, then another front potentially moves into the area next weekend. Highs mainly remain in the 90s with lows in the 70s through the long term period. && .AVIATION (18Z SATURDAY THROUGH MONDAY)... VFR CIGS should prevail during the period with occasional pockets of mid to high-level cloud cover. Isolated to widely scattered -SHRAs/- TSRAs are once again possible this afternoon but the best focus will likely occur south and east of the I-35 corridor. Confidence on TAF sites seeing any precip remains very low for this TAF forecast so have kept mention out of the TAFS for now. Winds should remain light at 10 kts or less from the east-northeast to east-southeast. Overnight and continuing into Sunday morning, winds relax and should become variable while remaining under 10 kts for all TAF sites. && .PRELIMINARY POINT TEMPS/POPS...
