NWS Greenville-Spartanburg, SC wrote its last area forecast discussion before the first event at Aug 26, 8:48 PM EST, 1 hour 25 minutes earlier.
Area Forecast Discussion National Weather Service Greenville-Spartanburg SC 948 PM EDT Fri Aug 26 2022 .SYNOPSIS... A more typical late-August pattern will continue into next week. Above-normal temperatures, and afternoon and evening thunderstorm chances with a mainly mountain focus, can be expected each day. The forecast becomes more uncertain next week, with the possibility for a cold front either drifting south across the area and leading to mid-week drying, or moving back north and bringing in increased moisture. && .NEAR TERM /THROUGH SATURDAY/... As of 945 PM EDT Friday: Radar has generally quieted down late this evening, but with isolated showers continuing to develop along the numerous lingering outflows from the earlier evening convection. Instability continues to wane and all last vestiges of shower activity should dissipate by around midnight or shortly thereafter. The main concern for the overnight is that many locations received heavy rainfall today and mid and high-level debris clouds will steadily thin out - possibly permitting some areas of fog to develop again across the region. The fog is not expected to be as widespread or dense as occurred Friday morning, but patchy dense fog will certainly be possible. The mountain river valleys will see the best chance of dense fog forming around daybreak. Anticipate continued mild overnight minimum temperatures running some five degrees above normal. Saturday looks a bit quieter across the area. There is some indication that a weak back door cold front might not make as much southward progress as earlier thought, and a short wave dropping down across the region during the day looks largely devoid of dpva. The latest run of the HREF indicates that showers and storms will develop during peak heating, but not to the same extent as today. This suggests a typical August day with precip probs not much better than chance over the mtns and slight chance east of the mtns, with temps maybe a few degrees above normal. Won't rule out an isolated severe storm based on model profiles that show decent mid-level dry air and an inverted-V in the boundary layer. && .SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/... As of 200 PM EDT Friday: A positively-tilted trough continues to lift northeastward Saturday night, as a cold frontal boundary settles to the south. Heights rebound through the second half of the weekend as the subtropical high becomes more and more prominent over the eastern CONUS. By Sunday morning, the front should have completely crossed the CWA, and accordingly, most deeper moisture is shunted off to the south and east of the region by Sunday afternoon. Winds quickly veer to ESEly, however, and allow enough low-level moisture to build into profiles that 800-1200 J/kg appears warranted outside the mountains. SREF members indicate a 60-70% chance for 1000+ J/kg, with a notable minimum across the Appalachians. Overall, however, the convective environment looks stunted; multiple guidance sources depict a shallow subsidence inversion which should keep updrafts from becoming very vigorous, and the GFS, at least, depicts fairly anemic DCAPE despite dry upper levels. It appears that moisture will be so shallow it'll have more a restrictive effect on updraft maintenance than an enhancing effect on severe potential. That said, steering flow will be extremely weak (on the order of 1-3kts) and PWs will cap out in the 1.6-1.7" range, so even with the fairly tight ensemble spread depicted by the GEFS and SREF alike, whatever storms or showers do develop will be stationary and capable of producing isolated heavy rainfall. Monday looks to more or less be a similar setup to Sunday, with weak ridging in place over the region and shallow moisture at the mid- to low-levels. Severe risk once again looks inhibited, with better chance of isolated heavy rainfall. Temperatures both afternoons will be a category or two above normal. Some uncertainty on lows given questionable cloud cover overnight, but should be at least a category above normal. && .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/... As of 220 PM EDT Friday: Subtropical ridging continues to deteriorate Monday night as a deep Z500 low over Saskatchewan and Ontario drives heights down and exerts influence over the region. A trough on the periphery of this feature works its way across the Midwest and sharpens over the Ohio Valley through late Tuesday, and this looks to drive a surface cold front into the Carolinas by early Wednesday. Notwithstanding some slowing as the front exits the Appalachians, the GFS and EC depict this front settling east of the CWA by Thursday, allowing deeply dry profiles to work in through the end of the period. The CMC as well as a number of its ensembles depict a completely different setup, with a potent upper low splitting off the base the advancing trough on Tuesday. This alternative setup results in the front largely halting before it reaches the Carolinas and lifting back north as a warm front, placing the Carolinas in a robust warm sector as cyclogenesis takes hold over the Ohio Valley. This would result in a much more active and less dry setup for the remainder of the period, with chance to likely PoPs each afternoon. It's far too early to say which of these setups will ultimately arise. && .AVIATION /02Z SATURDAY THROUGH WEDNESDAY/... At KCLT and Elsewhere: Thunderstorms have generally dissipated across the region late this evening, but lingering isolated activity will have to be monitored near KAND since this area did not get worked over by the earlier storms. Otherwise, lingering convective debris clouds aloft will thin out late this evening and early overnight, which should permit lower clouds and fog to form in locations where heavy rain recently fell. Evening updates to the TAFs have added some IFR restrictions at KGMU and KGSP to go with the existing IFR to LIFR conditions featured at KAVL and KHKY. KCLT will need to be monitored closely for IFR cig/visibility, but will hold at MVFR for now and just hint at lower conditions with FEW010 cigs. Saturday looks a bit less active, with coverage higher in and near the mountains. Expect mainly light and variable winds, except gusty near any thunderstorms, settling out to a more southerly direction through the day on Saturday. Outlook: Daily, mostly diurnal convective chances continue into the early to middle part of next week. Fog and low stratus are possible each morning across the mountain valleys and anywhere that received appreciable rainfall the previous day. && .GSP WATCHES/WARNINGS/ADVISORIES... GA...None.
