FXUS64 KSJT 200004 AFDSJT Area Forecast Discussion National Weather Service San Angelo TX 704 PM CDT Tue May 19 2026 ...New AVIATION... .KEY MESSAGES... - Severe Storms possible this afternoon and evening. - Medium to High (30-80%) chances for showers and thunderstorms from Tuesday evening through Friday. && .SHORT TERM... (This evening through Wednesday) Issued at 106 PM CDT Tue May 19 2026 Isolated to scattered thunderstorms have developed early this afternoon, with some being severe. Expect these storms to continue developing and expanding in coverage through the rest of the afternoon and evening. Most CAMs eventually expand this convection into a somewhat organized MCS, and move it south into south Texas later tonight. The main concerns will continue to be large hail and damaging winds. In addition, precipitable water values are between 1 and 1.5 inches, and with the generally slow movement of these storms, flash flooding will also be a concern. For Wednesday, CAMs disagree with each other on the coverage and intensity of possible convection, but with a boundary in the area, the moisture remaining in place, and continued southwest flow with embedded shortwave energy, we will likely have another at least medium (20%-40%) chance for showers and thunderstorms, mainly during the afternoon as afternoon heating affects the area. We will continue to see at least a Slight Risk for severe storms, mainly for our southern counties Wednesday. && .LONG TERM... (Wednesday night through next Tuesday) Issued at 1235 PM CDT Tue May 19 2026 An active weather pattern will persist through much of the long term with a persistent upper level southwest flow with disturbances moving across our area. Also, the combination of a cold front south of the area and abundant moisture(PW values 1 to 1.5 inches) will bring a risk of localized flash flooding, especially Wednesday night and Thursday as the WPC has a slight risk of excessive rainfall along and south of the I-20 corridor. Also, there is and isolated flash flood threat this weekend across the southeast part of the area. There are medium to high chances of rain for at least a few days in the long term. Also, there is an isolated severe weather threat(marginal risk) for the southern 2/3 of the area Tuesday evening across the Concho Valley and Northern Edwards Plateau. The main hazards will be large hail and damaging winds. Temperatures will be cooler with highs in the upper 70s and 80s, around to slightly below normal for this time of year. && .AVIATION... (00Z TAFS) Issued at 652 PM CDT Tue May 19 2026 Showers and thunderstorms will continue to impact the southern terminals over the next 3-4 hours. Brief reductions in visby and gusty winds will accompany the strongest storms. Most of the activity will move out of our area by midnight. MVFR (and possibly IFR) cigs will spread into northern portions of the area overnight. Will include MVFR cigs at KABI and KSJT. Less confident in how far southward cigs will spread but will continue to monitor the next TAF package. && .PRELIMINARY POINT TEMPS/POPS...
