Area Forecast Discussion National Weather Service Greenville-Spartanburg SC 152 PM EDT Fri Aug 1 2025 .SYNOPSIS... One last hot and humid day on tap with widespread showers and thunderstorms developing through this evening. A few strong to severe storms, as well as isolated flash flooding, will be possible with today's diurnal activity. Cold air damming develops this weekend and lingers into the new workweek bringing much needed relief from the heat and humidity in the form of cooler and below normal high temperatures. Shower and thunderstorm chances stick around through next week but a lull may develop Sunday into Monday. && .NEAR TERM /THROUGH SATURDAY/... As of 1250 pm Friday: The last of the remnant low cloudiness was finally exiting the fcst area, while convective initiation has taken place over the ridges as expected. The development has been gradual as has been our destabilization, but we're on our way with sfc-based CAPE up into the 2000-3000 J/kg range. The dCAPE has been modest at best, but water vapor imagery has a pocket of somewhat drier air east of the mtns, so the expectation remains that it would be sufficient to support some stronger downdrafts and outflows. The wind shift boundary was already sinking south across the Upstate and northeast Georgia, but the effective front was still located to the north of the forecast area. No significant changes are noted with the Day 1 Convective Outlook update keeping most of the fcst area in a Marginal Risk for damaging wind gusts. The 12Z HREF and the morning runs of the HRRR continue to support the idea that we will have just enough shear to promote some multicell organization on cold pool mergers and outflows. If we can get the storms organized as they move east off the Blue Ridge as is hinted by the HREF, our chances of severe wind gusts will go up. There's also the risk of excessive rainfall that extends into the evening hours, what with very deep warm cloud potential and precipitable water well over two inches. The concern will be anchoring of storms near the Blue Ridge Escarpment because of easterly low level flow opposing the westerly mid/upper flow, or multiple rounds of storms over the same area. A Flood Watch has been contemplated, but the expectation at this moment is for only isolated/localized threats. Oh yeah, and today will be the last hot day. No changes to the Heat Advisory over the Lakelands. The effective cold front should drop southward across the forecast area late this evening behind the main deep convection, and in behind, the low level northeasterly flow will improve. There should be enough moisture left over to be run upslope on the east side of the mtns to force additional showers well into the overnight near the Escarpment in NC, as the effective front oozes S and SW across the Upstate into northeast GA. That should keep rain chances in play for most of the region with perhaps the exception of the NW Piedmont where the dry air arrives first. Low temps will still be near normal. Saturday is another tricky day as the guidance continues to show a nascent cold air damming wedge early in the day. The parent high moving east over the Great Lakes looks relatively weak, but the low level northeasterly flow has sufficient low level moisture to keep a thick cloud deck underneath the developing inversion. How far the wedge boundary makes it will have a big impact on the weather. Some of the guidance stalls the front over the southwest part of the fcst area through the day, providing enough forcing to produce numerous showers, but the CAMs in the 12Z HREF are relatively quiet, suggesting that boundary clears the fcst area early in the day. The fcst follows the NBM and maintains a relatively high precip prob, but not without a healthy dose of skepticism about the extent of the precip. Either way, the clouds should keep us from being able to warm up much and high temps should struggle to get out of the 70s. The downward trend in temps continues. If the precip doesn't develop, we might be more like upper 70s than the mid 70s we will have in the forecast. It will feel a whole lot different than the last month, that's for sure... && .SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/... As of 108 PM EDT Friday: Weak, broad cyclonic flow aloft over the eastern CONUS will linger through much of the forecast period. ~1024mb surface high will set up shop over the northeastern CONUS by Saturday as the near-term front sags south of the CFWA. Drier surface air from the northeast will help to set the stage for a hybrid CAD event through the weekend into the early parts of next week. The latest SREF shows a LI between 3-5 indicating that the static stability is relatively strong for the time of year, especially in regards to a Summertime CAD event. Ongoing scattered showers are likely Saturday night as a decent Atlantic fetch (850mb wind: ESE @ 15-20 kts) filters in atop the CAD dome to go along with better isentropic lift. Extensive cloud cover and elevated precip chances will allow for overnight lows to run a few degrees below normal. A shortwave is seen rounding the base of aforementioned cyclonic flow aloft, while drier air continues to nose in from the northeast by Sunday. The wedge boundary will be far south of the area and essentially choke any really deep moisture flux from filtering into the region. In this case, precip coverage will be less, with the southwest mountains and Upper Savannah River Valley being the most likely locations of receiving rainfall due to the closer proximity to the boundary. Some form of scattered showers is shown per model guidance of breaking containment further north in the CWA. Cloud cover will remain extensive as the area remains locked into the CAD pattern. As a result, afternoon highs on Sunday should end up 12-18 degrees below normal, bringing in much needed relief from the heat. Not too much of a pattern change on Monday, but parent high slips further offshore into the Northern Atlantic, while the area will be under more of an in-situ CAD. Model trends are drier for Sunday night into the daytime period Monday. A digging shortwave trough is shown over the central CONUS by Monday afternoon, allowing the flow aloft to become more south to southwesterly. This is turn will enhance the moisture flux provided by the stalled boundary to the south and gradually work north. This should allow for more scattered showers to work into the area, but not growing in coverage until later Monday. In these types of setups, scattered showers are possible throughout the duration of a CAD, which is why mentionable PoPs remain in the forecast through the forecast period. SREF and deterministic guidance are not excited with any elevated instability, so only stratiform precip is expected outside of a rogue thunderstorm through the short term. Some changes are on the horizon during the extended period, but the CAD dome remains locked in through Monday as afternoon highs will run 8-12 degrees below normal as some peaks of sunshine may start making it to the surface. && .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/... As of 143 PM EDT Friday: Upper trough will shift towards the Eastern third of the CONUS, while a surface high becomes reinforced over New England and Atlantic Canada later Tuesday into Wednesday. This will help to keep the surface cool layer in place and static stability high as the LI remains near a value of 3-5 through much of the workweek, emphasizing a lingering CAD event. Better moisture flux will reach the area by Tuesday as the flow above the surface turns southerly being on the leeside of the upper trough as it slowly travels further east. In this case, PoPs will ramp back but not excited about the thunderstorm potential as there is only some form of elevated instability. However, this is the summertime so you can never truly rule it out. The Atlantic subtropical ridge will begin to deepen by the latter half of the period, while the ridge over the southwestern CONUS aids in the weakness of the trough over the southeastern CONUS. This will allow for more diurnal convective, especially over the mountains by the end of the forecast period and for a gradual warming trend to occur. The CAD is shown eroding by late into the workweek through either a coastal low or surface wind divergence per model guidance. Temperatures remain a category or two below normal, especially during the daytime period through D7. && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/... At KCLT and elsewhere: Currently VFR at all terminals and it should stay that way outside of thunderstorms this afternoon, though storms will become more and more numerous over time because of a favorable buoyant convective environment. The immediate concern is the storms, which are a good bet at all terminals, so a TEMPO was deployed some time starting between now and 21Z across the region. A wind shift boundary has moved across most of the area with the exception of KAND, so winds should be N to NE thru the period once that boundary clears KAND in a few hours. Storms should persist well into the evening as a moisture boundary sinks slowly S and SW, so a PROB30 was used to convey those restrictions. We will amend often. Once the second boundary moves through, northeast flow will increase and low level moisture will become even more plentiful, quickly developing an MVFR ceiling restriction that drops to IFR well before sunrise on Saturday. A weak cold air damming wedge will develop early Saturday that should hold the ceiling restriction across the region through the end of the period. Outlook: Widespread cig restrictions may linger through Saturday night. The rest of the weekend looks VFR apart from the usual low stratus and/or fog each morning. Scattered to numerous showers and a few thunderstorms are also possible Saturday, mainly during the afternoon and evening. A return to more typical summertime weather is expected early next week. && .GSP WATCHES/WARNINGS/ADVISORIES... GA...Heat Advisory until 7 PM EDT this evening for GAZ029. NC...None.
