163 FXUS64 KSJT 092351 AAA AFDSJT Area Forecast Discussion...UPDATED National Weather Service San Angelo TX 651 PM CDT Thu May 9 2024 ...New AVIATION... .SHORT TERM... (This evening through Friday) Issued at 200 PM CDT Thu May 9 2024 Tornado Watch in Affect through 9PM CT tonight across the Northwest Hill Country, Heartland, Eastern Concho Valley, and Southeast Big Country. Strong to Severe Thunderstorms are expected this afternoon and evening mainly across the Heartland, Northwest Hill Country, Eastern Concho Valley, and Eastern Big Country. Large hail, Damaging Winds, and Isolated Tornadoes are possible across these areas through 9PM tonight. Cooler temperatures are expected behind the cold front tonight into Friday, with temperatures only reaching into the mid 70s to lower 80s. Another round of showers and thunderstorms are possible Friday from the Southwest, potentially affecting the Northern Edwards Plateau, Northwest Hill Country, Concho Valley, and Western Heartland. Storms that do develop are not expected to become as severe as we are currently expecting this evening. && .LONG TERM... (Friday night through next Thursday) Issued at 321 PM CDT Thu May 9 2024 Cooler temperatures this weekend with an unsettled pattern. An upper low will be over the Nevada/Arizona border Friday night, and will move over the Four Corners area by Saturday evening. The low is progged to move across the western half of Kansas Sunday night, with a trough extending south across our area. An embedded disturbance or two will be moving over our area ahead of this system. With this setup and increased lift/moisture in our area, we have medium to high PoPs (40-80 percent) for showers and thunderstorms Saturday through Sunday. Rain chances should largely dwindle Monday with a weak cold frontal passage, and as the aforementioned trough shifts east of our area. Less cloud cover and a return to southerly winds will result in warmer temperatures Tuesday, with highs in the upper 80s to lower 90s. Our area will have another chance of showers and thunderstorms Wednesday afternoon into Thursday, when an upper trough is progged to move into the southern Plains. The details are more uncertain that far out, however. After highs in the upper 80s and lower 90s Wednesday, temperatures may be a little cooler Thursday in the wake of a cold frontal passage. && .AVIATION...
