Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
254 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 SATURDAY/...
A line of strong to severe thunderstorms is taking shape across the
Upstate. A 44kt wind gust was observed by the KAND ASOS as the line
was taking shape across the upper Savannah River Valley. This is not
surprising considering the axis of 1000+ dCAPE depicted in
mesoanalysis across the area. Overall coverage and intensity of
convection is expected to increase as it moves into an area
characterized by 2500-3000 sbCAPE and upper support continues to
improve 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
continued clustering along cold pools, supporting a risk of
localized damaging winds, especially across the Piedmont.

A lull in convection of at least a couple of hours appears to be in
the offing late this afternoon/evening. However, we will have to
monitor convective trend across the TN Valley (ahead of the cold
front) this afternoon, as any activity developing that way could
find its way into our far western areas this evening. So far, the
air mass across East Tennessee is struggling to recover from the
morning showers that moved across that area. However, numerous,
albeit not especially strong showers and storms are developing at
the leading edge of an axis of 2000+ sbCAPE across west/middle
Tennessee. The more robust shear remains across the Ohio Valley, and
given the rather modest levels of instability, especially east of
the Cumberland Plateau, it doesn't appear likely that this
convection will be able to get its act together in much of an
organized form. Nevertheless, we will feature likely pops across the
mtns this evening, tapering to chances east of the Blue Ridge for
scattered to numerous showers and a few storms moving into our
western areas this evening.

With low level moisture remaining abundant, and mid/upper level
clearing, fog formation is possible late tonight, especially in
sheltered areas, where it could become locally dense. Deeper
moisture and wind shift associated with cold front is expected to
ooze to our southern areas, or just to our south by sunrise
Saturday. Token small pops will be maintained in these areas
through the day, as well as across the mtns (for a relatively moist
NW flow), and across the eastern zones (due to upper level thermal
trough developing in association with Mid-Atlantic upper low).
Otherwise, drier and stable air will preclude the need for pops
elsewhere, while lower thickness values will support max temps
slightly below climo.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
As of 200 PM EDT Friday: A deep trough will extend southwest from a
closed low pressure system over the DelMarVa area through the
western Carolinas Saturday night through Sunday. Deeper moisture
will wrap southward around the back side of the system to contribute
some cloudiness to the northern tier, but any shower chances
Saturday night into early Sunday look rather low. Northerly cold
advection flow will maximize during this period with thicknesses
bottoming out across the region to produce min/max temps 1 to 2
categories below climo.

Meanwhile, at the surface sprawling high pressure will build from
the upper Midwest to the east coast and nose southward through the
western Carolinas and northeast Georgia through Monday. Modest
surface dewpoint recovery will begin in southwest sections by Monday
afternoon, but the potential for any southwest mountain ridge
diurnal convection looks quite limited.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
As of 210 PM EDT Friday: The eastern trough will broaden in the
Tuesday to Friday timeframe as it gets reinforced by rounds of
digging shortwave energy arriving from Manitoba and Ontario. Under
the developing broad ridge, the airmass over the southeast will
continue to modify through the week with temperatures gradually
returning to normal. Diurnal convective coverage from terrain
forcing will increase each afternoon Tuesday through Thursday.
Deeper moisture will pool ahead of a cold front approaching from the
northwest on Friday to generate above climo PoPs.

&&

.AVIATION /19Z 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.
