250 FXUS64 KEWX 131910 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 210 PM CDT Thu Jun 13 2024 ...New SHORT TERM, LONG TERM... .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 thoughout 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 diurmally 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... (18Z TAFS) Issued at 1146 AM CDT Thu Jun 13 2024 A rather quiet forecast compared to the last several days as TS is not expected through the day today. Some VCSH was added at SAT and SSF to account for weak convection developing along a boundary situated over the central portion of the CWA. VFR CIGs and Visby`s can be expected through the period. Winds should generally remain less than 10 kts and transition back and forth from eastern to southerly. There is an outside shot at some MVFR CIGs at SAT and SSF after sunrise Friday, but confidence is too low to include in the TAF at this time. && .PRELIMINARY POINT TEMPS/POPS...
