589 FXUS64 KSJT 141714 AFDSJT Area Forecast Discussion National Weather Service San Angelo TX 1214 PM CDT Wed Aug 14 2024 ...New AVIATION... .SHORT TERM... (Today and tonight) Issued at 220 AM CDT Wed Aug 14 2024 Expect hot temperatures again today as a strong upper level ridge builds over the area. A Heat Advisory remains in effect for the Big Country until 9 PM this evening. Please follow heat safety precautions if you have to be outside. Highs today will be 102 to 105 across the Big Country with heat indices a few degrees higher. Highs will be in the upper 90s to around 103 elsewhere. Overnight lows will be in the 70s. Also, expect elevated fire weather conditions across much of the area and will issue an RFD for today. && .LONG TERM... (Thursday through Tuesday) Issued at 310 AM CDT Wed Aug 14 2024 ...Dangerous Heat Wave Expected This Weekend... No changes are expected in the forecast for later this week through early next week. On Thursday, an upper trough should move across the northern and central Plains. Weak surface troughing and a slight moisture increase Thursday afternoon could result in a few showers developing over the higher terrain from the Panhandle southward to the Permian Basin. For now, chances for rain were kept low on Thursday afternoon and evening due to lowering confidence levels. Even with some low rain chances the searing heat will continue. This weekend through early next week, an upper-level ridge should rebuild across Oklahoma and north Texas, leading to hotter temperatures. This heat wave could potentially be stronger and more widespread than what we saw earlier this week as 850mb temperatures could reach 24-27 deg C and 591 dam heights could extend all the way to the northern Plains by Sunday. High temperatures during this period look to reach 105-110 degrees for most locations, especially the Concho Valley and Big Country. Assuming this comes to fruition, Heat Advisories will likely be needed for consecutive days this weekend. Those who will be participating in outdoor activities this weekend, especially those related to the start of the school year, are advised to take precautions to limit exposure to the dangerous heat. && .AVIATION... (18Z TAFS) Issued at 1214 PM CDT Wed Aug 14 2024 VFR conditions through the next 24 hours. There will be a few gusts accompanying south/southeast winds through the early evening, before winds diminish to around 10 knots or less through the overnight hours. && .PRELIMINARY POINT TEMPS/POPS...
