429 FXUS64 KSJT 111812 AFDSJT Area Forecast Discussion National Weather Service San Angelo TX 112 PM CDT Mon Aug 11 2025 ...New SHORT TERM, LONG TERM... .KEY MESSAGES... - Not as hot this week with a chance of isolated to scattered showers and thunderstorms Monday through Wednesday. && .SHORT TERM... (This evening through Tuesday) Issued at 112 PM CDT Mon Aug 11 2025 A few showers and thunderstorms have developed just from the western low rolling plains into the Big Country early this afternoon. High resolution models generally dissipate this convection before sunset, but have updated the afternoon forecast to include at least a 20% chance for showers and thunderstorms north of a Sterling City to Brownwood line. Although we`re not expecting widespread severe weather, there is plenty of instability available for these storms, so a few could briefly approach severe levels. Later tonight, high resolution models continue to bring a cluster of thunderstorms southeast into the area after midnight. How far south these storms will make it is the main question. The best chance for rain from these storms will be in the Big Country. With precipitable water values in the 1 to 2 inch range, heavy rainfall and localized flooding will be a concern, along with a lesser concern for gusty winds approaching 60 mph, and large hail. Expect there to be a lull in convection mainly during the mid and late morning hours. By tomorrow afternoon, the atmosphere will be able to recover, and there should be outflow boundaries laying around from the morning convection that new convection will be able to develop off of. Therefore, will have generally 30% chances for thunderstorms tomorrow afternoon across most of the area, although not all locations will see precipitation. Once again, the main concern will be locally heavy rainfall, with a lesser chance for a few of the storms to approach severe levels. && .LONG TERM... (Tuesday night through next Monday) Issued at 112 PM CDT Mon Aug 11 2025 Late Tuesday into Wednesday, an upper level ridge will remain centered across the the Desert Southwest, with a weak upper level trough across the Great Plains. A weak cold front will likely be stalled somewhere across the forecast area. At least isolated showers and thunderstorms may linger into Tuesday evening, but placement will dependent on how far south convection overnight progresses. The current thinking is that the outflow boundary/cold front associated with the convection overnight will stall across southern portions of the area, and this placement would keep the higher rain chances across the southern half of the area. On Wednesday, isolated to scattered showers and thunderstorms will again be possible, especially near the remnant boundary. Highs will be slightly below normal, in the low to mid 90s for most locations. On Thursday, the upper level ridge across the Desert Southwest will weaken, while an upper level ridge near Florida strengthens and begins to shift west. This feature will slowly build toward Texas through the weekend, resulting in slowly increasing temperatures and mainly dry conditions. Highs through the period will generally remain in the 90s, but a few locations (especially across the Big Country) could approach 100 degrees by the end of the weekend. && .AVIATION... (18Z TAFS) Issued at 1237 PM CDT Mon Aug 11 2025 Mainly VFR conditions at all sites through the next 24 hours. However, there is a chance for TSRA to affect KABI, mainly after 06Z tonight. There are a few isolated SHRA to the west of KABI at this time, but expect these to remain clear of the site through this afternoon. Winds will be east/southeast through this evening, with winds becoming light and north, or variable. && .PRELIMINARY POINT TEMPS/POPS...
