Area Forecast Discussion National Weather Service Greenville-Spartanburg SC 340 AM EST Sun Dec 29 2024 .SYNOPSIS... A strong cold front will cross the area this morning into this afternoon bringing the potential for severe storms and locally heavy rainfall. High pressure will briefly dry things out on Monday, before another round of light showers arrives Tuesday. Much colder and drier conditions expected Wednesday thru the weekend. && .NEAR TERM /THROUGH TONIGHT/... As of 330 AM EST Sunday... Key Messages: 1) Strong to Severe Storms Expected this Morning and Afternoon Ahead of a Strong Cold Front 2) Moderate to Heavy Downpours May Lead to Nuisance Flooding through this Afternoon, Mainly Along the Blue Ridge Escarpment 3) Winds Increase through this Afternoon Ahead of the Front Becoming Gusty Patchy to locally dense fog continues this morning across the forecast area, especially east of the mountains thanks to cold air damming. The SPS for patchy dense fog remains well placed and this will continue through 5am. Not anticipating the need for a Dense Fog Advisory this morning heavier rain ahead of an approaching cold front will push across the forecast area throughout the early morning hours and will help scour out any remaining dense fog through daybreak. Light rain also continues lifting north across portions of extreme NE GA and western NC this morning thanks to cold air damming remaining in place ahead of the cold front. Lows this morning will end up ~20 degrees above climo thanks to thick low clouds and precip. Attention now turns to the severe weather potential this morning into this afternoon as a strong cold front pushes across the forecast area. Already seeing some thunderstorms pushing into the southern NC mountains this morning ahead of the front. Winds will gradually increase ahead of the front this morning and early afternoon becoming gusty. Opted not to issue a Wind Advisory as any locations that could see gusts flirt near advisory criteria will be confined to the higher elevations of the NC mountains. The front will gradually erode the wedge through the morning hours, allowing us to gradually destabilize through the day. Although SBCAPE looks minimal through the morning, 40-50 kts of deep layer shear and a few hundred J/kg of MUCAPE will allow strong to severe storms to develop. This afternoon deep layer shear increases to 50-60 kts ahead of the front and 200-500 J/kg of SBCAPE looks to develop (thanks to the eroding wedge). Thus, the severe threat will continue through the afternoon hours as the front progresses east. The primary hazard with any severe storm that develops is damaging wind gusts but there will be a secondary isolated tornado threat as well. Additionally, locally heavy rainfall may lead to some nuisance flooding, mainly along the Blue Ridge Escarpment, where an additional 1.5-3.0 inches of rain is likely to fall through early this afternoon. CAMs agree that a strong line of convection will develop ahead of the frontal boundary so the strongest winds are expected to be directly along the leading edge of the line of storms. The 06Z HRRR and NAMNest show the line of convection pushing across the forecast area early this morning into early this afternoon before exiting the eastern edge of the CWA around roughly noon to 1pm. If this timing holds, then the bulk of the severe weather threat should end prior to peak heating. However, both models depict another line of convection developing directly along the frontal boundary late this afternoon into early this evening (during prime peak heating hours). Thus, another round of isolated strong to severe storms could develop behind the main line of convection but confidence on this is low as a residual cold pool is likely to develop behind the bulk of the morning convection. Wind gusts should gradually taper off late this afternoon into this evening behind the front. Highs this afternoon will climb into the mid 50s to mid 60s thanks to strong S/SW'ly flow ahead of the front. Drier conditions are expected this evening into tonight behind the front for most locations, although some NW flow rain showers look to develop along the NC/TN border. Lows tonight will be noticeably cooler but will still end up ~10-15 degrees above normal. && .SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... As of 144 AM EST Sunday: Quiet conditions will continue Monday as a potent upper trough pulls away to the northeast and an ill-defined ridge of high pressure overspreads the Southeast U.S. Temperatures will climb into low 60s outside the high terrain amid clear skies and perhaps some weak downslope flow early in the day. Monday night, cloud cover will increase again as deep-layer southwesterly flow develops ahead of the next upper wave. This feature will drift across the Carolinas on Tuesday and into Tuesday night, spurring another round of rainfall beginning before dawn Tuesday. Tuesday morning, temperatures will be warm enough even in the mountains that we can expect an all-rain forecast...but Tuesday night, locations along the NC-TN state line can expect a brief transition to snow as temps fall below freezing. Elsewhere, lows will remain in the upper 30s or even low 40s...and rain will be rapidly vanishing anyway. && .LONG TERM /WEDNESDAY THROUGH SATURDAY/... As of 203 AM EST Sunday: The upper pattern will remain fairly dynamic through the end of the week, with a series of upper speed maxes pushing across the region Thursday, Friday, and Saturday. Generally speaking, it'll be too dry for any impact to the western Carolinas, apart from ushering in much colder temperatures. The exception will be Friday night, when a lobe of moisture dipping off the Cumberland Plateau into the Tennessee Valley may produce a round of NW flow snow along the NC-TN border. For now, totals still look sub-advisory in all but the most aggressive ensemble solutions. Temperatures will fall below normal beginning Wednesday night...with highs only in the low 50s through Friday, and as low as the mid 40s on Saturday...and lows in the 20s every night, even outside the mountains. && .AVIATION /09Z SUNDAY THROUGH THURSDAY/... At KCLT and elsewhere: Cold air damming remains in place as of 06Z ahead of an approaching cold front leading to LIFR to VLIFR cigs and vsbys across the terminals as well as -SHRA/-RA/-DZ. The cold front will push across the terminals early this morning (just prior to/near daybreak) into this afternoon. This will help gradually erode the cold air damming wedge throughout the day as well as bring heavier SHRA, along with TSRA, to the terminals later this morning into early this afternoon. Thus, have PROB30s for all terminals from from this morning into this afternoon to account for TSRA and associated restrictions. Gusty to strong and variable winds are expected with any thunderstorms or heavy showers that develop. LLWS will be a concern for the terminals through late this morning or early afternoon as the wedge gradually erodes. Thus, have this accounted for in the 06Z TAFs. LIFR to VLIFR restrictions should continue ahead of the heavier SHRA activity early this morning, with LIFR to IFR restrictions returning as +SHRA/TSRA track over the terminals. Winds will gradually turn SE'ly east of the mountains through daybreak before turning SW'ly this afternoon into this evening ahead of the front. Winds at KAVL will start out SE'ly this morning before gradually turning S/SW this afternoon. Winds will turn WNW'ly at KAVL early this evening behind the front. Wind speeds will gradually increase ahead of the front through early this afternoon, becoming gusty. Winds will peak early afternoon before gradually tapering off late this afternoon into this evening. Drier conditions are expected to develop behind the front late this afternoon/early evening so VFR conditions will return during this timeframe as well. Outlook: Dry high pressure returns briefly on Monday before another cold front brings showers and associated restrictions back on Tuesday. Elevation dependent rain/snow showers linger across the mountains Tuesday, possibly moving over KAVL with brief restrictions. Dry high pressure returns for Thursday. && .GSP WATCHES/WARNINGS/ADVISORIES... GA...None. NC...None. SC...None. && SYNOPSIS...MPR NEAR TERM...AR SHORT TERM...MPR LONG TERM...MPR AVIATION...AR
