925 FXUS64 KEWX 241120 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 620 AM CDT Mon Jun 24 2024 ...New AVIATION... .SHORT TERM... (Today through Tuesday) Issued at 200 AM CDT Mon Jun 24 2024 The upper level ridge centered over and northwest of the area will continue to produce for most locations a dry forecast through the short term. Beneath the ridge is a pool of elevated moisture across the Coastal Plains and there is a 10-20% chance of stray to isolated tropical showers and thunderstorms in forecast this afternoon across this area. A few CAMs bring stray showers near the San Antonio metro area early in the evening. Activity should dissipate after sunset. Again, most locations will stay dry. Otherwise warm and humid conditions. This afternoon, some isolated spots in the Coastal Plains and near the I-35 corridor could see peak heat index values of around 105-108 degrees. We will issue a Special Weather Statement for this. Heat index values and the heat risk increase slightly Tuesday afternoon. && .LONG TERM... (Tuesday night through Sunday) Issued at 200 AM CDT Mon Jun 24 2024 Typical summer pattern over South Central Texas mid week through next weekend and beyond. Subtropical Ridge remains centered near or over our area. Subsidence under the Ridge and a seasonally moist airmass yield no rain over most areas. Except, the seabreeze may provide enough forcing to overcome the subsidence to generate a shower or thunderstorm or two near the Coastal Plains on most afternoons. Nearly seasonally hot temperatures prevail. Dewpoints may not mix as efficiently resulting in elevated heat indices. Thus, Heat Advisories are possible each day for parts of South Central mainly along and southeast of the I-35 corridor. && .AVIATION... (12Z TAFS) Issued at 620 AM CDT Mon Jun 24 2024 Stratus was producing a mix of MVFR and IFR ceilings mainly along and west of the I-35 corridor. The stratus is expected to scatter out 14Z-16Z. A 10-20% chance of isolated SHRA/TSRA activity is forecast in the afternoon across the Coastal Plains. A few convective allowing models bring this isolated activity toward the SAT area around 00Z. Confidence and coverage is low, and therefore have excluded mention in the SAT/SSF TAFs. && .PRELIMINARY POINT TEMPS/POPS...
