Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
242 PM EDT Mon Jun 25 2018

.SYNOPSIS...
Scattered thunderstorms will impact the area again this afternoon
and evening with damaging winds possible. A weak cold front will
drop through the forecast area tonight, bringing more seasonable
temperatures Tuesday. A passing trough will increase chances for
showers and storms Wednesday, with hot weather returning to end the
week.

&&

.NEAR TERM /THROUGH TUESDAY/...
As of 2pm EDT Monday.  Round of thunderstorms, some possibly severe,
is just beginning this afternoon across the CWA.  SBCAPE is good
with afternoon heating, though MLCAPE is more moderate.  Windshear
is moderate as well, and activity is being assisted by propagation
of upstream system. Per CAMs, thunder is anticipated to continue
through the evening, with activity becoming focused more to the east
after 7pm and ending after 10pm.  Upper flow is weak and westerly,
but a shortwave has developed in association with MCS propagating
into the area.  As system passes by this evening, surface trough
moves further off shore and surface ridge becomes established with
high pressure building-up east of the Appalachians in a warm-season
wedge set-up.  Sagging frontal boundary becomes a wedge front
Tuesday morning, bringing somewhat cooler air with low overcast
across the region.  Despite cooler and cloudy conditions on Tuesday
due to wedge, enough instability developes in the afternoon for some
thunderstorms, though with less coverage and intensity than ones
today.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
As of 120 pm Monday: Cyclonic mid/upper tropospheric flow will
quickly return to the forecast area early in the short term, before
the upper trough axis shifts to the East Coast late in the period.
Surface boundary will be sliding south and west across the area at
the start of the period, with short term model guidance depicting
strong low level convergence along the boundary, along with not-too-
shabby warm sector instability (and it is a June front, so
instability extends for at least a couple of hundred miles to the
"cool" side of the boundary).  Meanwhile, with strong instability
still likely to develop Tue pm across the TN Valley, clusters of
convection will have plenty of opportunity to end up in our forecast
area through at least the first half or so of the period.
Slow-moving back door fronts this time of year are red flags for
potential flash flooding, as they provide ample opportunity for
training and/or anchored cells, and in fact the latest runs of the
GFS and NAM are signaling this potential in producing blobs of heavy
rainfall across the southern half of the area Tue evening.

Surface boundary will wash out and the air mass modify rather
quickly by mid-week, with strong instability likely developing
across the area Wed afternoon/evening, as the trough axis and
attendant front/surface trough are progressing across the TN Valley
and southern Appalachians. Another round of at least scattered
convection is therefore expected during this time, supporting 40-60
pops across the area. Increasing height gradient associated with
approaching trough will yield modest deep-layer shear, which should
be sufficient to allow some degree of convective organization posing
an enhanced threat of locally damaging winds. Increasing
anticyclonic flow aloft, along with lower theta-E area spilling into
the area should allow for a significant draw down in convective
activity Thu afternoon, although small chances for terrain-
influenced diurnal convection will still exist. Temps will be near
normal to begin the period, but return to several degrees above
climo by Thursday.

&&

.LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/...
As of 130 PM EDT Monday: Mid level high pressure will be centered
over the eastern states for the extended period leading to continued
hot conditions with mainly diurnally driven showers and
thunderstorms. The hottest day of this period looks to be Friday
when the mid level high is closest overhead. The combination of the
actual temperature and the humidity will lead to peak heat indices
near 105 in the Piedmont region. As the high moves off to the
northeast of the area Saturday through next Monday, it will be
slightly less hot with peak heat indices 100 to 105 outside the
mountains.

&&

.AVIATION /19Z MONDAY THROUGH SATURDAY/...
At KCLT and elsewhere: Thunderstorms with outflows approaching
severe limits are expected all areas this afternoon through the
evening as a complex of storms currently across KY/TN/AL/GA
propagates southeastward.  Weak front currently oriented northwest-
southeast across CLT may help provide additional focus at times, but
front is diffuse, and severe storms are possible all areas.  Thunder
moves west to east across the area, exiting after 2 or 3Z.  Gradual
southwest movement of front will continue to veer winds at KCLT,
though weakness of pressure gradient will keep winds light to
variable many locations.  Main trough associated with front moves
east, allowing a cold-air-damming surface high to bring
northeasterly winds and low-overcast into the area by early Tuesday
morning at KCLT, and other locations later.  Some light rain/drizzle
is expected behind the wedge front; and by Tuesday afternoon, models
develop some CAPE again, despite CAD conditions, giving some chance
for thunderstorms.

Outlook: Through midweek, a slow-moving or stalled front will
enhance coverage of SHRA/TSRA, mostly in the afternoon/evening.
Patchy morning fog and/or low stratus may increase as well in
mountain valleys and/or locations with wet ground.
