217 FXUS64 KEWX 271953 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 253 PM CDT Thu Jun 27 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Tonight through Friday night) Issued at 125 PM CDT Thu Jun 27 2024 A disturbance over the eastern portion of the upper-level ridge centered over far west Texas may allow for some thunderstorm development over Central Texas mid to late afternoon. A few isolated showers or storms could form over the Hill Country, northern I-35 corridor and coastal plains, with any activity ending this evening after peak heating. Additionally, any outflow boundaries may also kick off some isolated convection late this afternoon. Besides the aforementioned areas, the forecast calls for continued dry weather. Hot conditions continue today and tomorrow with a Heat Advisory in effect through this evening for the I-35/I-37 corridor and areas east and then again tomorrow afternoon and evening for the same locations. Highs today and tomorrow and will be from the mid 90s to around 103 degrees with heat indices from around 105-112 degrees. There is another low end chance for precipitation Friday afternoon, this time over the far eastern coastal plains, associated with a weak inverted trough. Coverage would be isolated with most remaining dry. && .LONG TERM... (Saturday through Thursday) Issued at 125 PM CDT Thu Jun 27 2024 Slightly more stable conditions build in Saturday with temperature trends and Heat Advisory messaging likely to be similar to that of Friday. A weak disturbance moving west across the Bay of Campeche could briefly lower heat indices Sunday into Monday with some inland moving showers extending well north into South Central TX. Coverage should be low as well as the potential for any "warnable" hazards. The rest of the extended looks humid and stable with more heat advisory headlines probable going into the middle of the week. Just outside the 7 day forecast deeper onshore flow becomes possible again, so there is some hope that we can get some more relief from the heat and drought in the form of air-mass showers and storms. && .AVIATION... (18Z TAFS) Issued at 1231 PM CDT Thu Jun 27 2024 VFR conditions are expected through the period. There is a low end chance an isolated thunderstorm develops in Central Texas late this afternoon near AUS, but confidence is too low to include in the TAF. Southerly to southeasterly wind continues through the period mainly at or below 12 knots. Gusts up to 20 knots possible at DRT through 02Z. && .PRELIMINARY POINT TEMPS/POPS...
