Area forecast discussion, Jun 21, 6:16 PM CDT, 29 minutes before
Area Forecast Discussion National Weather Service San Angelo TX 616 PM CDT Mon Jun 21 2021 ...New AVIATION... .SHORT TERM... (This evening through Tuesday) Issued at 147 PM CDT Mon Jun 21 2021 As of early afternoon, a cold front was moving southward through the Big Country and was located just north of I-20. The airmass south of this boundary is fairly unstable with CAPE values of 4000-5000 and lapse rates of 8-9 deg C/km. RAP soundings across our county warning area show dry air from about 800mb-500mb and DCAPE values of around 1000J/kg, which has the potential for damaging winds from wet microbursts that may occur. PWAT values of 1.5-2.0 inches also shows the potential for locally heavy rainfall after the initial damaging wind threat. So the big question: Where will these storms develop? Conventional wisdom and CAM solutions show activity developing on or just ahead of the front as it pushes southward this afternoon. The timing should intersect nicely with peak daytime heating late this afternoon and evening, allowing storms to develop into east-west multicell clusters along I-20, with another area in the Concho Valley and Edwards Plateau. This activity should continue southward in a fairly ragged fashion, and will move into the Hill Country after sunset. Some post-frontal showers and a few thunderstorms are possible, but the damaging wind threat should subside by then. Overnight, as the cooler air moves in, widespread cloud cover will develop underneath the frontal inversion, mainly south of I-20. Lows tonight should be about 10-15 degrees cooler than last night. Tomorrow, the cooler airmass should remain in place with generally northeast winds, turning east by afternoon. Overcast skies in the morning should break up with heating by noontime. These factors should allow high temperatures to be in the low to mid 80s, which will be a welcome relief from the blast furnace conditions of the last few days. && .LONG TERM... (Tuesday night through next Monday) Issued at 150 PM CDT Mon Jun 21 2021 Upper level high pressure will return to West Central Texas Tuesday night into Wednesday. Subsidence from this upper high will likely result in sunny skies and afternoon high temperatures climbing into the mid 90s by Wednesday. Temperatures will continue to climb into the mid 90s to around 100, Thursday and Friday. As the upper level high weakens on Saturday, afternoon high temperatures shouldn't be as warm. The ECMWF and GFS prog an upper level high pressure system to build across the Western U.S. this weekend. This type of pattern should bring upper level northerly flow across West Central Texas early next week. This type of pattern should bring cool frontal passages along with chances for rain and below normal temperatures to the region by early next week. && .AVIATION... (00Z TAFS) Issued at 615 PM CDT Mon Jun 21 2021 Isolated to widely scattered thunderstorms are possible this evening along the I-10 corridor and Heartland and have VCTS at the southern terminals until 05-06Z. Expect MVFR ceilings to develop at most of the terminals between 03Z-06Z and remain through 18Z Tuesday. Also, going IFR at the KJCT site by 09Z Tuesday. The winds will be north to northeast with gusts of 25 to 30 knots this evening. && .PRELIMINARY POINT TEMPS/POPS...
