Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
901 AM EDT Wed Jul 20 2022

.SYNOPSIS…
Seasonally hot and muggy conditions will continue through the week.
There will be a chance of mainly afternoon and evening thunderstorms
through the week as well. An upper level disturbance will pass to
our north on Thursday with an attendant frontal boundary increasing
our chances for severe weather. Expecting the hot ridge over Texas
to nose into our area by this weekend with temperatures several
degrees above normal.

&&

.NEAR TERM /THROUGH TONIGHT/…
As of 900 AM EDT Wednesday: Latest vis sat and metars show stratus
expanding across the Upstate and into the southern NC Piedmont under
a slowly thinning mid and high cloud deck. The stratus should thin
out by noon, and mid clouds should be mostly dissipated as well,
as an MCV drifts to our east. Should see temps back up to our
normal if not slightly above again today, with another round of
scattered showers and tstms by mid-aftn thru early evening. Overall,
no major changes needed to the forecast with this update.

Quite a bit of elevated instability is shown in forecast soundings
across the area this morning, becoming surface based by afternoon.
Another short wave drops across the area with some upper divergence
as well. The forcing acting on this instability will keep showers
across the area through the morning with thunderstorms for the
afternoon. CAM guidance agrees on this scenario but disagrees on
where the greatest coverage develops. Still, the preponderance of
the evidence suggests the entire I-85 corridor and south will have
the greatest coverage, after a greater coverage of showers across
the mountains in the morning. Shear remains modest but moderate
instability is possible. DCAPE may reach the 750 J/kg range
and surface-delta-theta-e values will again be relatively high.
Therefore, a few severe storms are possible. Isolated flooding is
also possible given the high PW values. Highs will be near normal
but higher dew points today will least to heat index values around
100, especially along and south of I-85.

Expect the storms to diminish by early evening with loss of heating
and the forcing moving east. However, showers may linger, especially
across the mountains. Convection may actually increase overnight,
especially across the mountains, as another wave moves toward the
area from the NW possibly inducing an MCS which moves into the area
by daybreak. Will have to keep an eye on this development. Low
clouds and patchy fog will also be possible. Lows will be a few
degrees above normal.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/…
As of 200 AM EDT Wednesday: Stout upper low over Ontario/Quebec
will displace broad height falls from the Upper Midwest to
the northeastern CONUS with an attendant frontal boundary. The
forecast is still for the boundary to sag towards the CFWA from
the north during the daytime period on Thursday. During peak
heating, the frontal boundary will enter the northern tier of
the CFWA and provide a foci for numerous to widespread coverage
in convection. The environment ahead of the boundary will have an
abundance of instability and moisture available. Although wind shear
will be weak overall, enough mid-level shear (15-25 kts @ 700mb-
500mb) and strong destabilization should allow for organized
convection to get underway through cold pool/MCS development along
and ahead the boundary, which will uptick the severe storm potential
across much of the CFWA. Any thunderstorm cluster will also provide
an isolated flash flood threat, but storm motion should be fast
enough to lower this threat overall. Damaging winds, isolated large
hail, localized flash flooding, and dangerous cloud-to-ground
lightning will be the primary threats for Thursday afternoon/evening.

Most of the convective activity should wane off overnight Thursday
and push southeast of the area. The boundary is expected to
stall over the CFWA by Friday as drier air filters in behind the
boundary. Residual moisture and diurnally driven instability will
allow for convective initiation in the vicinity of the frontal
boundary, but this threat will stay confined to mainly the southern
half of the CFWA and should remain isolated to scattered in terms of
coverage. Nocturnal cooling will essentially shutoff any lingering
convection by Friday night. Temperatures will be up to 5 degrees
above normal through the short term period, with heat indices
potentially reaching the triple digits over the piedmont locations
during the afternoon hours both Thursday and Friday.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/…
As of 300 AM EDT Wednesday: Any remaining upper troughiness should
lift to the northeast by the weekend as stout subtropical ridging
sets up shop over the southeastern CONUS. Current model guidance
keeps the subtropical ridge axis over the region through much
of the extended. As a result, the main weather headline will be
the heat. Temperatures will range from 4-8 degrees above normal
through the entire period. Dewpoints will likely mix-out during
peak heating, which could help keep heat indices slightly below
Heat Advisory criteria level at this time. Dewpoints will still
remain muggy (upper 60s – mid 70s) and wouldn`t be surprised for at
least an impact-based Heat Advisory for portions of the piedmont
throughout the medium range. Only isolated diurnal convection
expected over the weekend due to the lack of a trigger mechanism
and an uptick in subsidence aloft. Global models still hinting
at some form of organized convection to threaten the CFWA by the
early part of next week within the northwesterly flow aloft as the
subtropical ridge`s northeast quadrant break down just enough for
this type of feature to come close to impacting the CFWA. Otherwise,
expect diurnally driven convection to gradually ramp back up by
the early to middle part of next week, while remaining hot.

&&

.AVIATION /13Z WEDNESDAY THROUGH SUNDAY/…
At KCLT and elsewhere: Isolated showers continue this morning.
Restrictions were not as widespread as expected. Where they have
developed, expect MVFR by mid morning and VFR by noon. Deep
convection still expected for the afternoon. Have TEMPOs or VCTS in
place. Storms diminish this evening but showers will linger across
the mountains and may even increase overnight as forcing moves in
from the NW. Restrictions may again be possible as well, but will
hold off for now given the uncertainty. SW winds will continue
through the period. KAVL will see NW wind become SW for the
afternoon then back to NW.

Outlook: Diurnal SHRA/TSRA return in greater numbers Thursday with
an above-average risk of microbursts. Small and less-impactful
diurnal convection returns mainly for the SC sites Friday and
Saturday. Fog and low stratus will develop before dawn each morning
in the major mountain valleys and where heavy rain fell the previous
night.
