Area Forecast Discussion National Weather Service San Angelo TX 203 AM CDT Sun Jul 11 2021 ...New SHORT TERM... .SHORT TERM... (Today and tonight) Issued at 202 AM CDT Sun Jul 11 2021 Line of strong to severe showers and thunderstorms south of the Red River Valley at 130 AM will be moving into Haskell and Throckmorton around 330 AM...and the I-20 corridor including Abilene between 530 and 630 AM. While the line of storms is expected to weaken, some storms may still be capable of damaging winds to 60 mph and penny size hail through daybreak. While the short range models indicate the storms diminishing early this morning, additional storm development is possible by mid afternoon with additional heating, and as a weak cold front moves into the Concho Valley and Heartland and dissipates. Surface based CAPES increase to 1500-2000 J/KG and MUCAPES 2000-2800 J/KG this afternoon, so there should enough instability for severe storms. SPC has a marginal risk of severe storms across much of West Central Texas north of I-10, with a slight risk over Callahan, Runnels, Coleman, Brown Counties today and tonight. Highs will likely be a couple degrees cooler due to clouds and storms, but still warm in the 90 to 93 degree range. Lows tonight will be near 70. && .LONG TERM... (Monday through Saturday) Issued at 138 AM CDT Sun Jul 11 2021 Anything left from the frontal boundary that is expected to move into central Texas on Sunday should wash out for Monday. But, any residual outflows from earlier precipitation may provide a focus for a few storms across the Concho Valley and I-10 corridor on Monday, mainly in the afternoon. At this point, storm coverage should be fairly low and will not likely be severe. Otherwise, highs should reach the upper 80s to around 90 areawide. Stratus and convective debris may hold down high temperatures in a few places as well. As we get into Tuesday and beyond, we'll start to see a slight pattern change set up. The upper ridge out west will continue to wobble around and fluctuate, while otherwise staying centered over the Desert Southwest. Global models show a series of 500mb shortwave troughs traversing the northern and central US through much of the week. Despite some instability during this time period, there is no real good focus for convection each day, save for an isolated afternoon pop-up shower. As a result, skies will gradually be sunnier with fewer clouds and rain chances, along with steady south flow at the surface. This should lead to high temperatures reaching closer to the mid 90s, which is right around our normal for mid July. Over the weekend, global models suggest a stronger shortwave bringing a cold front down into the southern Plains, which may introduce some rain chances, but this feature will be monitored as the week progresses. && .AVIATION... (06Z TAFS) Issued at 1248 AM CDT Sun Jul 11 2021 Line of showers and thunderstorms along the Red River at 6Z may affect KABI towards or after 11Z. There may a few storms mid to late morning to affect KSJT and KBBD. Additional convection may pop up mid afternoon across the terminals. Very heavy rainfall may lower visibilities down to less than 3 miles at times during storms. MVFR stratus otherwise will move north from the Hill Country and TransPecos, affecting terminals except KABI through mid morning. && .PRELIMINARY POINT TEMPS/POPS...
