Area Forecast Discussion National Weather Service Greenville-Spartanburg SC 1041 PM EDT Sat Apr 10 2021
SYNOPSIS. High pressure builds in behind a departing cold front Sunday into Monday, leading to drier conditions. Another cold front will likely cross the area during the middle of next week, but without much moisture to work with, this front may struggle to produce precipitation, and inactive weather could prevail through next Friday.
NEAR TERM /THROUGH SUNDAY/. As of 1030 PM: Convection has cleared the CWA. Some locally dense fog is likely across some of the mtn valleys and a swath of the Piedmont where an apparent cold pool remains, having been deposited by heavy precip earlier this evening. This fog should improve to some degree in the next few hrs, but with WAA continuing in the low levels most of the night, thinking the stratus will struggle to erode. Most areas will see near-zero PoP until later tonight, when lapse rates improve with base of shortwave swinging thru. Chances will tick upward after daybreak with any diurnal heating, but even then only slight-chance PoPs look warranted in light of the paltry response from CAMs. The rest of Sunday looks warm and dry with partly cloudy skies once the low stratus burns off. Temperatures will be in the 60s and 70s over the mountains, while the foothills/piedmont reach into the mid to upper 70s.
SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/. As of 230pm EDT Saturday: Fairly quiet weather pattern for Monday and Tuesday, with region in a dry post-frontal regime. Upper flow flattens as trough moves eastward, with a slight rise in thicknesses. Westerly to northwesterly surface flow behind front continues at a brisk 10 to 20 kts on Monday, with a gradual weakening of winds on Tuesday. Forecast soundings show a little moistening aloft and a littler recovery of depressed dewpoints on Tuesday, leading to some scattered clouds, and maybe an isolated brief shower in the mountains Tuesday afternoon. Highs and lows Monday and Tuesday look similar, and will run 5 to 10 degrees above normal.
LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/. As of 200 PM Saturday: An upper level low north of of the Carolinas situated over the Ohio Valley will track eastward into the western Atlantic Tuesday night into Wednesday. The associated cold front with this system will be east of the CWA at the start of the long term. This cold front will continue to push eastward Tuesday evening into Wednesday as Canadian high pressure builds in behind the FROPA across much of the central and eastern CONUS. Global models are in good agreement in trending drier for much of the extended forecast. Therefore maintained a slight chance for PoPs Wednesday into Friday in collaboration with neighboring WFOs and also due to a few models showing isolated chances. The cold front looks to stall across the northern Gulf of Mexico Thursday into Saturday. Meanwhile a low pressure system tracking out of the northwestern CONUS will fracture into multiple shortwaves. A few of these shortwaves will eject into the central CONUS. These shortwaves will interact with the stalled front to the south near the Gulf Coast potentially increasing rain chances for the region towards the end of the forecast period. High temps are expected to return to near normal or just a degree or two below normal in the extended.
AVIATION /03Z SUNDAY THROUGH THURSDAY/. At KCLT and Elsewhere: Areas of IFR cigs and locally low vsby will linger over some of the area tonight; ongoing WAA still looks likely to maintain the extant low cigs, and they may even expand overnight. Any low stratus will likely stick around for parts of the morning hours as the front slides across the CFWA during that time. Kept IFR/MVFR cigs in through ~14Z-16Z, with restrictions relaxing a bit and ending the TAF period with VFR conditions and low end wind gust.
Outlook: VFR conds return Sunday and prevail into early next week.
