124 FXUS64 KSJT 171903 AFDSJT Area Forecast Discussion National Weather Service San Angelo TX 203 PM CDT Tue Sep 17 2024 ...New SHORT TERM... .SHORT TERM... (This evening through Wednesday) Issued at 203 PM CDT Tue Sep 17 2024 ...Continued warmer than normal with dry weather... West central Texas remains under upper level ridging this afternoon. However, to our northwest, a shortwave is moving through eastern New Mexico and into the Texas Panhandle region. This is resulting in scattered thunderstorms moving northeast across northeastern New Mexico, and also lee troughing, allowing for a few gusts in our area out of the south and southeast. Although a few isolated showers are possible this afternoon and evening east of a Brownwood to Sonora line, as with yesterday, coverage is expected to be too sparse to be worth mentioning. Otherwise, the warm temperatures will continue, with lows tonight in the upper 60s to lower 70s, and highs tomorrow in the low to mid 90s. && .LONG TERM... (Wednesday night through next Tuesday) Issued at 144 PM CDT Tue Sep 17 2024 Upper-level ridging will continue over the area through the rest of the work week, as upper level troughs sit over both the west and east coasts of the United States. This will allow the above- normal temperatures to continue for much of this week, with forecast highs in the 90s. We could start to see a pattern change as the troughing over the west coast moves east. As the short wave trough approaches the southern Rockies, the ridge axis over our area will start to tilt, eventually weakening, and becoming more zonal by early next week. The strength, timing, and exact path of this short wave varies between models, impacting precipitation chances and temperatures for this weekend and early next week. Models have been going back and forth on whether or not this system will push a cold front through West Central Texas late this weekend and early next week. If we see a stronger and more southern track of the low, disturbances could move through aloft ahead of the shortwave, leading to rain chances on Saturday. We could also see a cold front develop and move through the area, leading to better rain chances and slightly lower temperatures for Sunday and Monday. However, there is still quite a bit of uncertainty with this system. If the shortwave is weaker and moves further north, we could see a mostly dry forecast for our area. && .AVIATION... (18Z TAFS) Issued at 1203 PM CDT Tue Sep 17 2024 VFR conditions expected through most of the next 24 hours. Models hint at the possibility of some MVFR ceilings at KSOA for a couple hours Wednesday morning. Will hold off on introducing anything at this time, and let future forecasts address this. Otherwise, south to southeast winds around 10 knots this afternoon, with a few gusts to around 15 knots. Winds will diminish to less than 10 knots after 00Z tonight. && .PRELIMINARY POINT TEMPS/POPS...
