Area Forecast Discussion National Weather Service Greenville-Spartanburg SC 1010 AM EDT Thu Sep 23 2021

SYNOPSIS. Cool and dry high pressure will build into the area behind a departing cold front today, and persist across the region over the next several days. Seasonable temperatures and mostly clear skies will continue through the weekend.

NEAR TERM /THROUGH TONIGHT/. As of 955 AM EDT Thursday: the latest visible satellite imagery continues to show bands of upslope stratocu streaming across a good chunk of the NC/TN border. As low-lvl moisture dries up, the cloud cover should gradually dissipate as we go into the early afternoon.

Otherwise, forget about that Meteorological Fall stuff and never mind that the autumnal equinox was yesterday. The atmosphere has decided that today is the REAL first day of autumn across northeast Georgia and the western Carolinas. A deep upper low over the Great Lakes will slowly move northward today and tonight, keeping an upper trof across our region. Almost as if on cue, this will allow sfc high pressure to build in with much drier and cooler air than we have had for the last ten days or so. NW upslope cloudiness over the mtns this morning should gradually diminish thru midday, in time to salvage a mostly sunny afternoon. East of the mtns, full sun is expected with a light NW/N wind. High temps will be on the order of 5-10 degrees below normal. All in all, our first day of picture perfect fall weather. The sfc high will settle over the mtns tonight, allowing temps to drop at least ten degrees below normal, but probably not cold enough to worry about frost in the mtns except for the very highest of elevations.

SHORT TERM /FRIDAY THROUGH SUNDAY NIGHT/. As of 230 AM Thursday: Gorgeous weather looks on tap for the first weekend of fall, as cool, dry high pressure settles over the area. The center of the sfc high will be over the forecast area Friday, then weaken slightly as a dry "cold front" slips thru the area late Saturday. This will likely be too dry for any mentionable PoPs, and just a brief increase in mid and high clouds is expected with the fropa. Winds may tick up slightly out of the west Sunday behind the front, but it shouldn't be a windy day by any stretch. Temps will be about 5 deg below normal Friday, and 5-10 deg below normal Friday night. Then a slow warming trend for Saturday and Sunday, with Sunday's highs around normal.

LONG TERM /MONDAY THROUGH WEDNESDAY/. As of 245 AM Thursday: Quiet weather looks to continue thru the medium range, as general upper-level troughing continues along the East Coast, keeping dry NWLY flow atop the forecast area. By the middle of next week, the deterministic models really begin to diverge, with the GFS building a fairly strong ridge in from the west, while the ECMWF and Canadian keep a deep trough over the area. If the EC is right, we could see at least some return of rain chances, but even then, it's not too great. The GFS keeps us dry right on thru the end of next week. For now, will continue to keep a dry forecast. Temps will moderate to slightly above normal for aftn highs. With dewpts remaining mainly in the 50s, overnight lows should still dip to near normal.

AVIATION /14Z THURSDAY THROUGH MONDAY/. At KCLT and Elsewhere: The dry air continues to filter in behind the long-departed cold front, but low clouds continue to develop in the NW flow upslope areas along the TN border. A broken ceiling hovering right around 030 will keep KAVL in and out of an MVFR restriction through mid-morning or so, but the low clouds should break up by 15Z at the latest as the moisture pulls out Otherwise. all sites should be VFR and will probably stay that way through the remainder of the period. Wind will be NW to N through the period. KAVL should have frequent gusts thru the daylight hours, but that should abate by sunset.

Outlook: VFR conditions will persist into early next week.
