562 FXUS64 KEWX 241922 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 222 PM CDT Mon Jun 24 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Tonight through Tuesday night) Issued at 213 PM 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... (Wednesday through Monday) Issued at 213 PM CDT Mon Jun 24 2024 The subtropical ridge will keep dry weather in place at the start of the long term. High temperatures will continue to be mostly in the 90s across the CWA Wednesday and Thursday. Afternoon dewpoints in the 70s may push heat indices (HI) to advisory levels over the Coastal Plains and I-35 Corridor Wednesday. However, slightly better mixing Thursday may keep HI below criteria. A trough at 500 mb will push the upper ridge to the west Thursday and this weakness on the eastern side may allow isolated convection over the Coastal Plains Friday and Saturday afternoons. Temperatures will be about the same for the end of the work week and weekend. Another uptick in dewpoint temperatures Saturday may push HI to advisory levels, but they drop back down again for Sunday and Monday. && .AVIATION... (18Z TAFS) Issued at 1219 PM CDT Mon Jun 24 2024 VFR conditions are forecast for the local area airports through at least the early overnight period. Low clouds are forecast to develop and affect the local terminals along the I-35 corridor overnight into the mid to late Tuesday morning time frame. VFR cigs return late Tuesday morning across all of the local area airports. && .PRELIMINARY POINT TEMPS/POPS...
