Area Forecast Discussion National Weather Service Greenville-Spartanburg SC 300 PM EDT Sun May 26 2024 .SYNOPSIS... Temperatures remain above normal through Monday. There is a risk of strong to severe thunderstorms from this evening until the cold front passes Monday evening. Cooler and drier conditions return tuesday through Friday. && .NEAR TERM /THROUGH MONDAY/... As of 230 PM EDT Sunday: Embedded shortwaves residing within the mean flow of flat upper ridging will provide the upper forcing for ascent needed to carry multiple waves of potential severe weather across the area. A digging upper trough over the Midwest will swing an attendant cold front towards the region, but won't reach the area until the end of the forecast period. PWAT values ~1.50" with height falls and increasing deep layer shear will support the chance for multiple chances of severe weather as the CFWA resides within a warm sector as stout southwesterly WAA filters into the region. Here is the current forecast as far as how the next 24-36 hours will evolve: Ongoing MCS continues to truck through the OH Valley and the northern extent of the TN Valley. The trends continue to support the southern flank of the bowing segment to graze the northern zones of the CFWA, mainly locations along and north of I-40. Outflows ahead of the line of convection will be the driving force for more thunderstorms to develop south of I-40. The environmental parameters support 2000+ J/kg of sbCAPE, increasing mid-level flow (35-40 kts) allowing effective bulk shear (0-6 km) to keep the bowing segment organized, while allowing for supercells to develop away from the segment, which will most likely impact the NC mountains through the Charlotte Metro. A few CAMs have a few developing across the Upstate, where more instability is available. Large hail and damaging winds will be the primary threat with any supercell that forms. An isolated tornado can't be ruled out, but low-level shear doesn't support strong tornadogenesis. The hail threat won't be present with the southern flank of the bowing segment, but will have a higher straight-line wind threat with DCAPE >1000J/kg, with a few quick spin ups possible, especially if embedded supercells can survive along the line. Expect this threat to begin within the next hour or two across the northern mountains and push east through the area by sunset, maybe a little later. In this case, the bowing segment should survive all the way through the area despite dealing with terrain as MCS Maintenance upticks through the evening. Temperatures will be in the upper 80s to near 90 ahead of the expected convection, making it one of the hottest days of the year so far. One thing to note, a second bowing segment is developing across west-central TN, behind the first and CAMs are struggling to pick up on it. Worried this might be a surprise in the area, but will need to monitor its evolution over the next few hours. The aforementioned bowing segment is just one of possibly three rounds of severe weather during the near term. A second round is likely to occur overnight as the ongoing convection over the Midwest currently travels eastward and maintains itself as it encroaches the region late overnight through mid-morning Monday. The environment doesn't support a persistent MCS through the CFWA, especially east of the mountains. Deep layer shear will increase slightly and elevated instability will be available when the second MCS moves across the area. If a strong cold pool can be generated, then there will be a surprise run across the CFWA Monday morning, with straight line damaging winds being the primary threat. The one good thing is that most of this activity is rather progressive and will lower the hydro threat, but localized flash flooding can't be ruled out. With convective debris and another round of storms overnight, expect overnight lows to remain 5-10 degrees above normal. Last, but not least, the third round that's possible during peak heating on Monday, but will need a few factors to come together for it to reach its full potential. This one will be dependent on how much the environment recovers from the second round of convection and if the atmosphere regenerate more instability. As of now, CAMs do exactly that, with dewpoints in the uppers 60s to near 70 and instability quickly redeveloping by peak heating, ahead of an incoming cold front. Deep layer shear will remain elevated (35-45 kts) and curved hodographs would support rotating supercells on Monday. The question will be if we can tap into any surface instability to take advantage of the otherwise really good kinematics in place. If instability becomes realized Monday afternoon, all three hazards will be possible (large hail, damaging winds, tornadoes) with upscale growth by the time the storms get into the eastern zones and east of the CFWA. The only thing about this forecast is that it will remain uncertain until we see what happens with the second round of convection that's expected overnight. Decided to lower temperatures slightly for Monday as convective debris will be hard to shake off, especially during the morning hours. As a result, afternoon highs on Monday will be at or slightly above normal. && .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/... As of 135 PM Sunday...Upper heights remain nearly zonal Tue which will help maintain dry conds and temps warming about 5-7 degrees abv normal. Surface td/s will mix out deeper than Mon and expect lower RH values making for a rather nice feeling day. Heights and thicknesses begin to drop Tue night thru Wed and with a cP airmass mixing in, don't envision a good chance of precip associated with incoming mlvl s/w Wed afternoon. So, kept the fcst dry and again another nice feeling day with low RH and highs closer to normal. Dry conds continue thru the overnight periods and really no good chance of dense fog as sfc tdd/s generally average arnd 10 F across the fcst area. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... As of 145 PM Sunday...No sigfnt changes were made to the ext range fcst. Still expect a mostly dry period as the mean h8-h5 flow aligns w/ly to nw/ly and continues to reinforce a cP airmass building down the east coast. The latest GFS swings a rather strong h5 s/w thru the pattern Fri, but moisture looks too limited to introduce precip. The going showery activity was maintained Sat as another ulvl wave approaches from the west which will have a better llvl GOM connection. Deep convection looks limited with this system, however, as the wave runs into a strong ridging aloft possibly subduing tstm development. Temps will remain arnd normal levels each and a limited fog potential continues each night due mainly to sfc dryness. && .AVIATION /19Z SUNDAY THROUGH FRIDAY/... At KCLT and elsewhere: VFR conditions expected until showers and thunderstorms develop and introduces associated restrictions. Wind should remain light south to southwesterly with a few low-end gusts. Scattered thunderstorms develop in the afternoon hours so all terminals get a TEMPO for the restrictions with timing based on the HRRR, mainly in the evening. For KCLT and KHKY, there is an outside shot at a severe thunderstorm. Expect for cloud debris to hang out through the evening and into the overnight. Another round of shower and storms with associated restrictions is forecasted to move into the area and tried to time this out with a PROB30 for all TAF sites. Guidance continues to spill MVFR cigs across the area in association with the second round of activity. Winds remain south to southwesterly through the period unless influenced by storms or outflow boundaries. A third round of showers and thunderstorms will be possible during peak heating Monday and will likely disrupt aviation operations once again, but the extent of this will depend on how the second round of storms evolves overnight into the mid- morning hours. Expect some form of cloud cover as cloud debris will linger due to the multiple rounds of showers and thunderstorms. Outlook: A unsettled pattern will linger into the early part of the week, allowing for diurnal shower and thunderstorm chances each day and at least patchy fog development each night/morning. Drier weather is expected by midweek. && .GSP WATCHES/WARNINGS/ADVISORIES... GA...None. NC...None. SC...None. && SYNOPSIS...DEO NEAR TERM...CAC SHORT TERM...SBK LONG TERM...SBK AVIATION...CAC
