Area Forecast Discussion National Weather Service San Angelo TX 601 PM CDT Tue Oct 26 2021 ...New AVIATION... .SHORT TERM... (This evening through Wednesday) Issued at 239 PM CDT Tue Oct 26 2021 ...Severe Thunderstorms Possible Overnight... The main concern overnight is the potential for strong to severe thunderstorms across much of the region. A dryline is forecast to sharpen just to the west of our forecast area, late this afternoon. The cap is forecast to be strong enough to inhibit shower and thunderstorm activity this afternoon. By early evening, a potent upper level trough will approach the area, along with a Pacific cold front. As this front overtakes the dryline by mid evening, and large scale ascent (from the approaching trough) overspread the region, showers and thunderstorms are forecast to quickly develop along the front/dryline. The current forecast leans heavily on the HRRR which initializes convection across our western county warning area (CWA) border. A few of the other CAMs are a bit farther east with initialization. A fairly unstable environment will reside across the region, along with abundant surface moisture (especially for this time of the year), with dewpoints mainly in the 60s. A few strong to severe thunderstorms will be possible as the line of thunderstorms moves across the region late this evening and into the early morning hours Wednesday. Large hail and damaging winds are the main concerns, although a tornado cannot be ruled out, especially across the Big Country. Most of the activity should move east of the area between 4 AM and 6 AM Wednesday. This activity is forecast to be moving at a fairly fast pace, so flooding doesn't look to be a big concern. Our current thinking is that most areas will see one quarter to three quarters of an inch, with localized higher amounts, especially in our eastern counties. Much cooler temperatures are forecast on Wednesday behind the front, with highs in the low to mid 70s. Windy conditions are forecast on Wednesday, with winds increasing to 20 to 30 mph, with higher gusts. Winds will likely be right around Wind Advisory Criteria, especially across the northern half of the region, so have opted to go ahead and issue a Wind Advisory for most of the area, except our southeast counties, from 10 AM to 5 PM. && .LONG TERM... (Wednesday night through next Tuesday) Issued at 239 PM CDT Tue Oct 26 2021 Expect windy conditions Thursday, due to a tight surface pressure gradient and vertical mixing from aloft. The winds will be north to northwest and 20 to 30 mph with gusts to 40 mph possible mainly during the late morning and afternoon hours. Also, winds will be gusty at times during the night time. The winds will let up this weekend. Also, expect cooler weather with highs in the 70s to lower 80s. Another cold front is due in next Tuesday, when even colder temperatures behind it for the middle of next week. Also, going with slight chance Pops for Tuesday. Otherwise, going with a dry forecast through the long term. && .AVIATION... (00Z TAFS) Issued at 555 PM CDT Tue Oct 26 2021 A line of strong to severe thunderstorms will affect all of the TAF sites tonight. This will occur between roughly 2z to 9z depending upon the terminal location. Expect gusty, erratic winds and reduced visibility due to heavy rainfall with this line of thunderstorms. Much of this activity should move off to the east by roughly 10z. Then, expect winds to remain strong and gusty as they shift to a more northwesterly direction on Wednesday. && .PRELIMINARY POINT TEMPS/POPS...
