Area Forecast Discussion National Weather Service Greenville-Spartanburg SC 648 AM EDT Sun Sep 27 2020

SYNOPSIS. Warm and fairly humid conditions will persist early this week, with rain chances increasing gradually until a cold front pushes through Tuesday. Dry and somewhat chilly weather is expected behind the front for the second half of the week.

NEAR TERM /THROUGH TONIGHT/. As of 520 AM: Dense fog continues to expand in coverage across the Piedmont, and have opted to issue a Dense Fog Advisory for all our Piedmont zones thru 9 AM.

Later this morning, the day will start out with cloudy for most of the area, with fog and low stratus taking a while to lift and scatter out. Much like yesterday, the low-level flow starts out NWLY, but backs to SWLY by 18z ahead of an approaching shortwave trough. Some mid and high clouds will stream in with this trough, and that could slow the burning off of the low clouds. This means there is some bust potential for a third day in a row for high temps. Planning to keep skies mostly cloudy and undercut the NBM forecast highs a category or so, which is right around normal, if not a deg or two below normal in spots. With more breaks in the clouds across the western zones this aftn, a little instability is expected, and with decent QG forcing with the approaching upper trough, isolated to scattered showers will be possible. The eastern 2/3rd of the forecast area look to remain dry thru at least sunset.

Tonight, sfc high pressure shifts east, while an upper trough crosses the forecast area. Shower coverage will expand east into the Piedmont, but should remain isolated to scattered. More cloud cover tonight should limit fog development, but patchy fog will be possible given the very moist conditions and continued light wind. Lows will be about 8-10 deg above normal, mainly in the 60s.

SHORT TERM /MONDAY THROUGH WEDNESDAY/. As of 200 AM Sun: A humid southwesterly flow will continue through Monday and Monday night, preceding a well-defined cold front. Overall forcing is not that remarkable during this time, with any DPVA or jet dynamics remaining off to our west. A decent amount of SBCAPE should develop diurnally, however, despite relatively poor lapse rates. Chance/scattered PoPs will be retained. Highs should top out above normal, near 80 for the Piedmont. Midlevel height falls Monday night, and the arrival of a modest LLJ or warm conveyor belt, will allow precip chances to remain steady, then increase just prior to the front. Deep moisture likely won't arrive until very late Monday night, so we're not looking at any real heavy rain threat until that occurs. Sfc-midlevel theta-E lapses however are fairly large, although instability is not enough to support much of a microburst threat.

The latest deterministic consensus depicts the fropa sooner than previous runs; a factor that had contributed to slower timing was a cutoff low forming within the parent trough, and subsequently riding up the front. That is now shown occurring later and further east . enough that the stalling effect would be more likely to occur after the sfc front has pushed through our CWA, Tuesday night. Still not looking like the greatest severe wx setup, with neither 0-1km nor 0-3km shear getting critically high until the instability has diminished and/or been carried east of the area. Current frontal timing however does offer a narrow window of opportunity for convection to organize along the front late Tuesday afternoon near I-77, and I imagine we will watch any such activity closely. PWATs do rise sharply ahead of the front beginning around daybreak Tuesday, and very small mbE vectors are suggested within unidirectional SW-ly flow. WPC is expected to place the I-77 corridor in a Slight Risk for excessive rainfall given the potential for training convection. Max temps for our southeastern zones likely will end up close to Monday's readings, but notably cooler temps will be noted over the mountains.

Although Wednesday's PoPs have been lowered, the low still could meander across the Piedmont in the afternoon, as depicted on 27/00z GFS and 26/12z ECMWF. Some elevated convection could occur beneath it; we will retain a small PoP on that note, and also given the poor run-to-run consistency seen over the past few days of progs. Breezy and cool conditions are expected.

LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/. As of 320 AM Sun: A deep trough will bring below-normal temps to the area for the late week period. The GFS/Euro/Canadian all depict a very weak shortwave ripple crossing the southern Appalachians Thursday, which in conjunction with moist westerly flow warrants a small PoP near the TN border and a portion of the NC foothills. Aside from that, expect dry weather lasting through Saturday night. Temps will turn chilly, first in the mountains, with min temps of upper 30s to lower 40s expected there Friday morning. They fall into the 40s for the remainder of the area Saturday and Sunday mornings. Winds should be fairly light with high pressure centered nearby, and it is possible some of the sheltered areas will see frost if the temps do dip into the 30s.

AVIATION /12Z SUNDAY THROUGH THURSDAY/. At KCLT and elsewhere: Areas of dense fog and low stratus have developed across the area, and will be around to start the 12z TAFs. A gradual improvement in vsby and cigs is expected thru the morning hours, similar to yesterday, but expected to get to VFR at all sites a little earlier than yesterday. Scattered showers and an isolated tstm or two will be possible to the west this aftn, expanding east into the Upstate sites and at KAVL this evening. So will introduce some PROB30 for SHRA at those sites. Not expecting any showers at KCLT until early Monday morning. Low cigs and patchy fog are expected to return tonight. Winds are expected to remain light, but tick up a little this aftn into tonight out of the SW (enough to favor stratus over fog).

Outlook: Moisture continues to increase heading into Monday, with unsettled weather expected thru at least the midweek. A strong cold front should push thru the area by the end of the week, bringing drier weather.
