189 FXUS64 KSJT 240550 AFDSJT Area Forecast Discussion National Weather Service San Angelo TX 1150 PM CST Sun Nov 23 2025 ...New AVIATION... .KEY MESSAGES... - Rain chances will continue tonight, with the potential for heavy rainfall and a few strong storms across the area. - A Flood Watch is in effect for the Concho Valley and much of the Heartland and Big Country through 8 AM Monday. - Cooler temperatures expected for Wednesday, with highs in the 50s and lows in the 30s on Thanksgiving morning. && .SHORT TERM... (This evening through Monday) Issued at 1242 PM CST Sun Nov 23 2025 Strong to severe thunderstorms are possible this afternoon and evening, along with a threat for locally heavy rainfall which will continue into the morning hours Monday. A potent upper level low centered near the Four Corners region will track northeast toward Colorado this evening and then across Kansas and Nebraska on Monday. Ahead of this feature, surface moisture is quickly increasing across the area. Dewpoints are forecast to rise into the upper 50s to lower 60s by late this afternoon across our western counties. Scattered to numerous showers and thunderstorms are forecast to develop this afternoon, mainly across the northern half of the area. Meanwhile, isolated to scattered showers and thunderstorms will develop to our west, across the Trans-Pecos region and Permian Basin. Supercells are possible, mainly producing large hail. This activity may approach our western counties by early this evening, with large hail still being the main threat (although damaging winds are also possible). Locally heavy rainfall is also possible with any storms that develop. The next concern becomes the potential for heavy rainfall late this evening into Monday morning, as large scale ascent increases with the approaching upper level low. Most of the CAMs indicate a band of showers and thunderstorms developing from the Concho Valley, northeast into portions of the Big Country and Heartland. The concern is that we will see training of storms, with the same areas getting hit by multiple storms. This may result in a corridor of high rainfall amounts, with some locations seeing 2 to 4 inches, or more. Exactly where this band of heavier rain sets up is the main question. Right now, we think that it will set up from the northern Concho Valley into southern portions of the Big Country, but a shift by 20 to 40 miles could make a huge difference on who sees the highest rainfall totals. Given the potential for flash flooding, a Flood Watch was issued for much of the Concho Valley, portions of the Big Country and the Heartland from 6 PM this evening through 8 AM Monday. A Pacific cold front will track across the area on Monday, ushering in drier air, with rain chances ending from west to east during the morning hours. Highs on Monday will be in the low to mid 70s. && .LONG TERM... (Monday night through next Sunday) Issued at 1246 PM CST Sun Nov 23 2025 The low pressure mentioned in the short term will be off to the east by the start of the long term period. The thunderstorms will also, therefore, be off to the east of our area as well. Cooler conditions will persist on Tuesday along with drier conditions. Higher pressure will slowly increase temperatures across the region on Tuesday. However, another cold front will drop temperatures across the region on Wednesday. Temperatures will once again climb into the mid 60s by the end of the week. For Thanksgiving Day, morning lows will be in the low to middle 30s. Highs will be in the middle 60s. && .AVIATION... (06Z TAFS) Issued at 1144 PM CST Sun Nov 23 2025 Showers and thunderstorms will increase through the overnight hours, especially at KABI and KSJT. Outside of these storms, IFR ceilings and patchy mist can be expected. Storms will clear the TAF sites by the mid morning hours. Ceilings will gradually improve to VFR by the late morning hours as winds become westerly. && .PRELIMINARY POINT TEMPS/POPS...
