NWS San Angelo, TX wrote its last area forecast discussion before this severe thunderstorm warning went out at Sep 30, 2:17 PM CDT, 1 hour 28 minutes earlier.
Area forecast discussion, Sep 30, 2:17 PM CDT, 1 hour 28 minutes before
Area Forecast Discussion National Weather Service San Angelo TX 217 PM CDT Thu Sep 30 2021 ...New LONG TERM... .SHORT TERM... (This evening through Friday) Issued at 149 PM CDT Thu Sep 30 2021 Showers and thunderstorms are developing across the Big Country early this afternoon, in advance of a weak cold front and some lift ahead of an upper low/trough over the Four Corners region. This system will advance east across New Mexico tonight and into West Texas by tomorrow afternoon. As an embedded disturbance approaches from the west, lift will increase through the evening hours, with convection increasing in areal coverage. A moderately unstable airmass is in place this afternoon, along with steep lapse rates and enough shear for a few severe storms to develop into the evening hours. The best chance for severe storms will generally be west of a Stamford, San Angelo to Sonora line, where large hail and damaging winds will be the main hazards. Convection is expected to overspread the rest of the area overnight, with the severe threat decreasing. In addition to severe storms, heavy rainfall and localized flooding will be a concern through tonight, just about anywhere across the forecast area as PWATS remain between 1.5 and 2 inches. For Friday, with additional upper level support, a stalled frontal boundary over the area and a moist airmass in place, additional showers and thunderstorms are expected. The main concern tomorrow will be heavy rainfall and localized flooding. Temperatures will cooler tomorrow, with highs in the upper 70s to around 80 degrees. && .LONG TERM... (Friday night through next Thursday) Issued at 215 PM CDT Thu Sep 30 2021 By 0Z Saturday, the upper low responsible for bringing substantial chances for showers and storms Thursday and Friday will be centered over southeastern Colorado, northeastern New Mexico, and southwestern Kansas. With shortwaves expected to continue rounding the base of the low providing of upper level support, plentiful atmospheric moisture with continued south/southeasterly flow through 850 mb (along with PWat values between 1.4-1.75 inches), and an expected stalled frontal boundary to continue providing surface lift, have kept widespread Likely PoPs through Friday night. As we move into Saturday, the upper low will continue to move northeast into Kansas before opening up into a trough early on Sunday. As the low moves northeast, rain chances will decrease across the area from west to east on Saturday. By 09Z Sunday, rain chances will come to an end across the area and skies will begin to clear out as drier air filters in behind the front. Lows Friday night will be in the low 60s behind the stalled front with mid to upper 60s ahead of the front. Highs on Saturday will stick in the upper 70s to low 80s due to enhanced cloud cover and rain chances. The rest of the long term looks dry and pleasant. An upper level ridge will follow in behind the aforementioned upper level low allowing for increased subsidence. The beginning of next week is expected to have plenty of sunshine and beautiful daytime highs in the upper 70s to low 80s with dewpoints in the low 50s and overnight lows in the mid to upper 50s. It looks as though we might finally get our shot at real fall as we head into October. && .AVIATION... (18Z TAFS) Issued at 1250 PM CDT Thu Sep 30 2021 Currently seeing VFR conditions across the terminals. Scattered to numerous showers and thunderstorms will develop initially across the northern terminals this afternoon and early evening, then spread south and east across the remaining terminals later this evening and overnight. Some hail and gusty winds possible mainly at KSJT and KABI through mid evening, with heavy rainfall possible as well. Expect lower ceilings and visibilities associated with convection. A weak cold front will move through the area this evening and overnight, with mainly MVFR ceilings developing after midnight. Additional showers/storms are possible into the morning hours. && .PRELIMINARY POINT TEMPS/POPS...
