449 FXUS64 KEWX 140001 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 701 PM CDT Thu Jun 13 2024 ...New AVIATION... .SHORT TERM... (Tonight through Friday night) Issued at 209 PM CDT Thu Jun 13 2024 A few isolated showers will remain possible through the afternoon and early evening. Since they will mainly be diurnally driven, expect any showers or storms that form to quickly dissipate after sunset. Temperatures overnight will stay on the muggy side as easterly to southeasterly surface flow continues. Subtropical ridging will build in over South Central Texas on Friday, effectively cutting off any rain chances for the region. Temperatures will warm slightly, into the mid to upper 90s for all locations outside of the Rio Grande Plains on Friday. After a few morning clouds, we should see mainly sunny skies throughout the day. Not much else can really be said about the short term period as heat and humidity dominate the forecast through the remainder of the period. && .LONG TERM... (Saturday through Thursday) Issued at 209 PM CDT Thu Jun 13 2024 The subtropical ridge will keep dry weather in place at the start of the long term. High temperatures Saturday and Sunday will mostly be in the 90s with triple digits confined to the Rio Grande region and southern I-35 Corridor. Afternoon dewpoint temperatures will remain mainly in the upper 60s to lower 70s keeping heat indices below advisory criteria. Sunday afternoon and Monday a midlevel trough will approach the TX coast from the Gulf and could produce some showers and thunderstorms over the Coastal Plains each afternoon. Chances will be better on Monday as the trough gets closer. Models are showing possible tropical development in the southern Gulf of Mexico into the middle on next week and increasing chances for convection into our CWA. Most of the activity will be diurnally driven with showers and thunderstorms during the afternoon and early evening each day Tuesday through Thursday. Chances will increase and push farther inland each day. && .AVIATION... (00Z TAFS) Issued at 658 PM CDT Thu Jun 13 2024 VFR conditions expected to prevail for the duration of the 00z TAF. cycle. Scattered showers have remained south of the KSAT and KSSF terminals for the past couple of hours so have removed vicinity mention in prevailing as any ongoing convection is anticipated to decline as we move into the overnight hours. There remains a low chance for some MVFR conditions Friday morning however confidence remains too low to mention in prevailing. && .PRELIMINARY POINT TEMPS/POPS...
