Area Forecast Discussion National Weather Service San Angelo TX 303 PM CDT Sat Aug 31 2024 ...New LONG TERM... .SHORT TERM... (This evening through Sunday) Issued at 136 PM CDT Sat Aug 31 2024 Scattered to numerous showers and thunderstorms will continue through the afternoon hours across much of West Central Texas. Most of this activity should begin to dissipate by mid to late evening. The main concerns will be dangerous lightning, brief gusty winds, and locally heavy rainfall. Similar to this morning, a few showers and thunderstorms may linger into the early morning hours, so some slight chance PoPs were continued, but expect overall much drier conditions overnight. Overnight lows will be in the upper 60s to lower 70s. On Sunday, an upper level ridge will remain centered near the Four Corners Region, with an upper level low across northern Mexico and southern Arizona. Similar to what we are seeing this afternoon, expect the development of scattered to numerous showers and thunderstorms by late morning or early afternoon across much of the region. Slightly better coverage is expected tomorrow versus what we are seeing today. The main concerns will continue to be locally heavy rainfall, brief gusty winds, and dangerous lightning. Highs will be below seasonal normals, in the mid to upper 80s. && .LONG TERM... (Sunday night through next Saturday) Issued at 303 PM CDT Sat Aug 31 2024 The main concern for the long term will continue to be the potential for a heavy rain event early next week. Currently, there is upper level troughing over the Great Lakes, with ridging over the southeast, and another upper level ridge near the Great Basin area. South of the Great Basin ridge is a weak upper low over southeastern AZ. Medium range models generally agree that this weak low will drift slowly towards west central Texas over the next few days, then move very slowly over the area while weakening. Although there doesn't appear to be any significant surface boundaries around, the weak low will combine with plentiful moisture at the surface to bring scattered to numerous showers and thunderstorms to the area, especially Monday into Tuesday. In addition, steering flow will be very weak, resulting in slow-moving storms that will be very efficient rainfall producers, likely resulting in locally heavy rainfall and flooding. Precipitation should taper off on Wednesday. Temperatures will be cooler Monday and Tuesday, with highs in the 70s to mid 80s, with highs getting back into the upper 80s to mid 90s by the end of the week. && .AVIATION... (18Z TAFS) Issued at 1207 PM CDT Sat Aug 31 2024 Scattered to numerous showers and thunderstorms will continue to develop across the area this afternoon, so have included a mention of thunder at all sites. Expect a decrease in activity by early to mid afternoon. VFR conditions will generally prevail, except within any thunderstorms. Winds will generally remain light through the next 24 hours. && .PRELIMINARY POINT TEMPS/POPS...
