205 FXUS64 KSJT 090528 AFDSJT Area Forecast Discussion National Weather Service San Angelo TX 1228 AM CDT Sun Jun 9 2024 ...New AVIATION... .SHORT TERM... (This evening through Sunday) Issued at 210 PM CDT Sat Jun 8 2024 As upper level ridging continues to break down through the day today, a shortwave troughing regime will begin to shift east out of the southern Rockies and into the Plains. As we move into the late afternoon and evening hours, upper level clouds are expected to increase across the area with winds out of the south staying elevated in velocity through much of the overnight period. This will help overnight lows across the area stay in the low to mid 70s. Overnight tonight, a cold front is expected to drop south into the Red River region just north of the area. Here it is expected to stall out during the day on Sunday. A surface low out in eastern New Mexico will keep our surface flow out of the southeast, bolstering the already ample low level moisture we have across much of the region. As the shortwave trough makes more progress into the area by the afternoon, scattered showers and thunderstorms may develop, especially around the Permian Basin, but realistically diurnal activity could pop up anywhere with the greatest axis of instability draped across eastern portions of our area. The bulk of the activity will likely be outside of the short-term forecast after 00Z Monday but isolated development around 21Z Sunday is certainly possible. The main hindrance to any severe activity will be the lack of effective shear across the area, forecasted around 20 kts during the afternoon. This would support more multicellular storm modes but some isolated instances of large hail and damaging winds can`t be ruled out. As such, SPC has added all of West Central Texas into a Marginal for their Day 2 Convective Outlook. Temperatures for tomorrow will be comparable to today with our western zones in the upper 90s to to around 103 with mid 90s across our eastern counties. && .LONG TERM... (Sunday night through next Saturday) Issued at 214 PM CDT Sat Jun 8 2024 Upper level ridge will remain centered west of the area with a little more northwest flow developing aloft for Sunday night into Monday and then Tuesday. Hard to cap northwest flow and this is no exception, with most model showing some level of convection developing at times for the period. However, models do have their differences in just where and and what time convection is most likely. Will continue to just run chance POPs in the 30%-50% range for much of the period between Sunday night and Tuesday and fine- tune the chances as it gets pinned down a little more. Cooler on Monday and Tuesday with additional cloud cover and maybe some storms keeping temperatures down. Center of the upper level ridge builds closer to the area for mid week and then eventually the ridge axis builds eastward farther into Texas and Oklahoma. This will bring dry conditions back to the area and allow temperatures to climb once again. Highs back into the upper 90s to around 100 to end the week and into the weekend. && .AVIATION... (06Z TAFS) Issued at 1222 AM CDT Sun Jun 9 2024 Some stratus is expected to develop over the Texas Hill Country towards daybreak, with some of this possibly reaching the KJCT terminal during the early morning hours. Will maintain a TEMPO MVFR group this forecast cycle and monitor trends overnight. Otherwise, expect VFR conditions to prevail across the terminals. Convection may develop west of the area late this afternoon and early evening, and possibly affecting the KSJT terminal towards the end of the forecast period. However, confidence remains too low to consider mentioning at this time. && .PRELIMINARY POINT TEMPS/POPS...
