Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
308 PM EDT Sun Oct 11 2020

.SYNOPSIS...
The remnants of post tropical system Delta will move off the east
coast on Monday. Gradual drying will occur through mid week despite
the approach and passage of a weak front on Tuesday. Drier high
pressure will settle in behind the front Wednesday through Thursday.
A sharper cold front will move through the region on Friday, with
much colder air arriving next weekend.

&&

.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
As of 150 pm Sunday: While the main area of heavy rain showers
associated with the remnants of TC Delta continue to push east of
the forecast area early this afternoon, there will be one last area
of concern immediately ahead of the upper trough axis, where
coverage and intensity of showers is steadily increasing across the
SC and GA Piedmont. Per the latest SPC Mesoanalysis, surface temps
in the mid to upper 70s have allowed the air mass to weakly
destabilize in this area to the tune of around 500-1000 J/kg of
sbCAPE. While bulk shear remains more than adequate for organized
convection in this area, the stronger low level shear and helicity
parameters have shifted east of the forecast area. with the weak
surface/in-situ CAD boundary lingering in the vicinity of I-85,
still wouldn't completely rule out a brief spin-up with any deeper
cells crossing this boundary through the afternoon.

Flash Flood Watch remains in effect for the Blue Ridge through the
evening hours, and this will be allowed to stand, as runoff issues
linger in many areas from the northeast GA mtns into the NC
foothills. While the organized flash flood threat appears to be
waning, the potential remains for localized excessive rainfall
rates, especially if any training cells are able to develop over
locations with very poor antecedent conditions. Showers will
otherwise taper off from mid through late evening, with only
lingering token small chances lingering after midnight. Drying mid
and upper levels atop unseasonably moist low levels will produce
favorable conditions for fog and/or low stratus, with (at least)
locally dense fog likely. Min temps will remain well above
climo.

&&

.SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/...
As 200 pm EDT Sunday: During the morning hours on Monday, the
remnants of Delta should be to the east of the cwa, near the
Delmarva. The associated shortwave will help eject what's left of
Delta offshore by Monday afternoon. Drier air begins to filter into
the mid and upper levels, while residual moisture in the lower level
sticks around. This can allow for a few showers to linger over the
course of the day, mainly in the northern tier, as an approaching
front begins to move in from the west. Most of the activity from
this system will stay confined to the higher elevations as the
frontal boundary scoots through the cwa from west to east by 12Z-15Z
Tuesday. After the frontal passage, zonal flow aloft and a surface
high will set up shop over the region. A post-frontal environment
will prevail as better weather is in the making for the middle part
of the week. Temperatures are expected to run above climo through
the short term as high heights and abundant insolation will be in
store during the period.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
As of 1255 pm EDT Sunday: Surface high pressure will be moving off
the mid Atlantic coast Wednesday evening as we will have one more
day of above normal temperatures on Thursday. Height falls will be
significant on Thursday over the northern Plains and upper
Mississippi Valley as a broad eastern trough begins to form.  As a
low pressure moves north from Ontario into Friday, a strong cold
front crosses the Appalachians.  The GFS has light precip over the
mountains with the frontal passage late Thursday night while it is
dry from near I-85 and south.  The ECMWF has a wide band of precip
with the front from late Thursday night through much of Friday
across the western Carolinas and NE GA. Consistent with the ongoing
forecast we expect a narrow zone of moisture along the cold front
with this zone being thinner further south.  Much drier and cooler
air will follow the frontal passage and frost/freeze concerns may
redevelop across the NC mountains for next weekend. Temperatures
will drop to about ten degrees bellow normal next weekend then
become milder going into the early part of next week. It may be a
while before the next significant rain.

&&

.AVIATION /19Z SUNDAY THROUGH FRIDAY/...
At KCLT and elsewhere: Relative lull in showers will soon come to an
end across the forecast area, as activity is gradually blossoming
within weakly unstable air across upstate SC. Scattered to numerous
showers and perhaps a few TS will spread northeast across the
terminal forecast area throughout the afternoon, warranting tempos
for reduced visby in SHRA. Again, TS cannot be ruled out, and A VCTS
has been included at the upstate SC terminals from late afternoon
into early evening, but overall coverage should remain limited.
Lingering showers should otherwise taper off by late evening or so.

Lingering IFR cigs should improve to MVFR, and possibly VFR late
this afternoon/evening. However, drying mid and high levels atop
continued very moist low levels is expected to result in widespread
low stratus and fog, mainly between midnight and sunrise. LIFR cigs
appear to be s slam dunk, and while IFR visby is generally forecast,
LIFR or even occl VLIFR is within the realm of possibility. Fog and
stratus should burn off at most sites during late morning.

Outlook: Mainly VFR conds are expected through the week, except for
perhaps areas of morning fog and low stratus, primarily in the
mountain valleys.
