What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Greenville-Spartanburg, SC wrote its last area forecast discussion before this severe thunderstorm warning went out at Aug 8, 2:35 PM EDT, 39 minutes earlier.

Area forecast discussion, Aug 8, 2:35 PM EDT, 39 minutes before
Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
235 PM EDT Wed Aug 8 2018

.SYNOPSIS...
An upper-level disturbances will move across the area this afternoon
and evening. A weak cold front will then approach from the northwest
tonight into Thursday and stall across the region through late week.
Seasonably warm temperatures and scattered to numerous afternoon and
evening showers and thunderstorms will continue into the weekend. An
upper level disturbance will move across the area on Monday leading
to a drier day on Tuesday.

&&

.NEAR TERM /THROUGH THURSDAY/...
As of 215 PM...Fairly solid coverage of convection can be seen
across eastern KY/TN attm, and is starting to look quasi-organized
into multi-cell clusters. Meanwhile, scattered convection is
starting to develop across the high terrain of the CWFA ahead of the
main activity. All this to say that we should see likely to
categorical coverage in the mountains thru the aftn hours. Deep-
layer westerly steering flow should take activity into the Piedmont,
highest across the NC zones. Effective bulk shear is still less than
20 kts on the mesoanalysis page, but SBCAPE is 3000-3500+ J/kg. So
an uptick in severe threat look on tap. There will also be a non-
zero risk of excessive rainfall, with PWATs slightly above normal in
the 1.5-1.75" range.

Convection should largely exit east of the area this evening, but
lingering showers will be possible along the TN border thru much of
the night, thanks to NWLY upslope flow. A weak front will slip in
from the NW. It is more of a wind-shift line than a front, but will
will allow slightly drier air to work into the area. Lows tonight
will be slightly above normal.

Thursday, a northern stream upper trough axis will slide east of the
area, while a weak southern stream trough drifts across the Ozark
Plateau. A slight bit of upper ridge atop the CWFA coupled with
slightly lower sfc dewpts should result in less instability than
we've had the last couple days. The latest CAMs show mainly isolated
to scattered aftn convection, favoring the SW half of the CWFA.
Highs will generally be a couple degrees cooler than today across
the area.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY NIGHT/...
As of 230 PM Wednesday: Broad upper troughing will remain in place
across much of the East through the period. Weak frontal zone/
surface trough will provide a low level focus for diurnal showers
and storms, with perhaps slightly higher than typical coverage
anticipated both Fri and Sat afternoons, esp across roughly the
southern 2/3 of the area, as more stable air will try to work its
way into northern areas in the wake of the boundary. Temps will
generally be right around normal through the period.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
As of 245 PM EDT Wednesday: A mid level trough will be a persistent
feature across the forecast area Sunday through Tuesday. A surface
boundary will meander across the area each day essentially being the
dividing line between deeper moisture to the east and somewhat drier
air to the west. Scattered showers and thunderstorms are expected
both Sunday and Monday in all parts of the forecast area but as the
mid level trough shifts east on Tuesday, most shower activity should
be limited to west of the continental divide.

Mid level ridging will build into the region for next Wednesday
leading to more typical mid August Pops.

&&

.AVIATION /19Z WEDNESDAY THROUGH MONDAY/...
At KCLT and elsewhere: The main concern for the 18z TAFs will be
timing of convection impacts. The latest guidance seems a bit too
slow on timing of convective initiation and so the latest TAFs keep
VCTS and TEMPOs a couple hours earlier than the consensus. This is
still the typical peak-heating time frame (18-24z). From there, a
light westerly flow should push everything off to the east this
evening, but with lingering mid clouds and some showers in the NC
mountains into the overnight. A weak front of sorts will push thru
by daybreak, shifting winds around out of the WNW/NW and allowing
slightly drier air into the region. This should result in a little
less storm coverage on Thursday. Fog will likely develop again
overnight in the mountain valleys, but maybe not as much in the
French Broad Valley due to a more persistent up-valley NW wind. The
other sites should be VFR, except in TSRA.

Outlook: Typical mid-summer conditions are fcst the next several
days. Diurnal, scattered thunderstorms will continue mainly in the
afternoons, with coverage increasing toward the weekend. Associated
morning restrictions will be possible each day, especially in
mountain valleys.
