Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
203 PM EDT Fri Jul 28 2017

.SYNOPSIS...
A strong cold front will cross the region from the west through
tonight. Cooler and drier air will arrive across the western
Carolinas and northeast Georgia through the weekend and linger
through the early part of next week. More typical summertime
conditions will return about the middle of next week.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 155 pm: Coverage actually diminished as previous widespread
showers and embedded storms moved into the western part of the
forecast area. However, as expected, scattered deeper convection has
been developing along the leading edge for the past hour or so. This
should continue to fill in a bit, as it moves into an area
characterized by 2500-3000 sbCAPE across the Piedmont and upper
support improves as height falls continue to overspread the area.
Height falls/tightening height gradient is expected to result in
improving shear throughout the afternoon, with 0-3km values likely
reaching 20-25 kts by late afternoon. This will be adequate to
support some degree of organization along cold pools, supporting a
risk of localized damaging winds, especially across the Piedmont.

The overnight period may see some lingering -shra and a couple tstms
over the far srn and ern zones with perhaps a few upslope -shra over
the wrn mtns. However, we will also have to watch for potential air
mass recovery ahead of the front across the TN Valley this
afternoon. If that happens, the combination of adequate buoyancy and
moderate shear will support the potential for development of
organized convection in these areas, which could approach the NC
mtns this evening. Otherwise...winds will shift n/ly and lowering
td/s will begin mixing in across the nrn zones. With winds remaining
elevated and mixed beneath a likely stcu deck...the possibility for
dense fg will remain fairly low outside sheltered mtn valleys and
fthill areas. Mins will remain above climo by a cat or so in this
setup.

&&

.SHORT TERM /SATURDAY THROUGH TUESDAY NIGHT/...
As of 300 AM EDT Friday: A pattern change is in store during the
short term, and it should be a welcome change. At the start of the
period, the surface front and associated initial vort max will have
passed just east of the area, with perhaps some lingering precip in
southeast zones, but the upper trough axis and primary vort max will
still be in place over the Appalachians with some northwest flow
showers possible early in the day. This will all dry out through the
day as much, much lower dewpoints advect into the region - at least
10 degrees lower Saturday afternoon than what we should see today.
This will be very noticeable with overnight lows Saturday night at
least 5 degrees below normal; mid 60s at best across the Piedmont
and 50s in the mountains. A nice, nice day expected on Sunday as the
trough digs through, with highs several (5-8) degrees below normal
on the backside of the upper trough with the CAA dominating.
Dewpoints in the 50s and really crazy pleasant for the last day in
July. There is some difference in placement of the upper trough
between the faster ECMWF and slower GFS, so if the latter works out
we could see a few more clouds.

Behind the trough axis, the Canadian surface high pressure will
begin building in more Sunday night into Monday, and though full sun
will allow temps to climb a couple of degrees higher than those on
Sunday, dewpoints will drop even further, with 50s in most areas and
even some 40s dewpoints showing up in the mountains during max
mixing. The upper wave will continue to broaden Monday night into
Tuesday as the surface high slides east across the mountains and
toward the Atlantic, with the airmass finally beginning to modify.
Still a couple of degrees below seasonal normals for Tuesday and
Tuesday night, but continued dry.

&&

.LONG TERM /WEDNESDAY THROUGH THURSDAY/...
As of 315 AM EDT Friday: During the dry short term, a shortwave will
dive out of the Rockies into the Southern Plains, reinforcing and
sharpening the broad trough already in place over the eastern third
of the country. Moisture will lift up from the Gulf, and the high
pressure in place over the western Carolinas and NE GA will continue
to modify, with dewpoints recovering into the 60s everywhere (though
still really not all that bad). A vort max sliding around the flow
at 500mb will push into the mountains, and with slowly increasing
moisture, should be enough for a return of some pops to the higher
terrain Wednesday afternoon. Flow aloft will transition to
southwesterly as the trough digs down the Mississippi Valley,
lifting more moisture out of the Gulf for Thursday. GFS is a little
slower with this return and again keeps convection mainly in the
mountains, but with the uncertainty, have trended back more toward
diurnal pops, but still slightly below seasonal normals for temps
(not too bad of a start to August!).

&&

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
At KCLT and elsewhere: Showers and storms moving off the Blue Ridge
are expected to expand in coverage and intensity as they move east
across the area through late afternoon. Tempos for TSRA are included
at all terminals...beginning now at all sites except KCLT, and at
20Z at KCLT. Occl visby and/or cig restrictions are likely during
brief periods of heavy rain. Showers and storms are expected to
diminish in coverage from late afternoon into the early evening.
However, additional activity developing ahead of a cold front over
the TN Valley may then move into the area during mid/late evening.
VCSH and Prob30s therefore linger into the early part of the
overnight at all TAF sites. The concern then shifts to the potential
for fog and/or stratus late tonight, as low level moisture remains
plentiful, and mid/upper levels begin to dry. For the time being,
late night/early morning restrictions are confined to KAVL/KHKY, but
more widespread restrictions are certainly possible. SW winds may
gust at times this afternoon, diminishing to 5-10 kts by mid-evening
or so. Winds then shift to the NW at most terminals by mid-morning,
with speeds of 5-10 kts expected (10-15 kts and possibly gusty at
KAVL).

Outlook: Drier air will filter in from the north behind a passing
cold front this weekend. Chances for morning fog and stratus will
also be possible mainly in the mountain valleys. A typical
summer-time pattern is expected to return by the middle of next week.
