The radar

The Knoxville radar (KMRX), 84 km from the middle of the area, began a volume at 22:16 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Peachtre/Fal Fld, GA (KFFC), launched 12:00Z, 10.2 hours before the alert went out and 244 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

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 28, 4:33 PM EDT, 1 hour 40 minutes earlier.

Area forecast discussion, Aug 28, 4:33 PM EDT, 1 hour 40 minutes before
Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
433 PM EDT SUN AUG 28 2016

.SYNOPSIS...
A tropical system will move toward the North Carolina Outer Banks
through Tuesday before likely moving back out to sea by mid week. A
cold front will approach the region from the northwest Wednesday
night into Thursday, with another tropical system likely emerging
from the Gulf of Mexico. There remains a great deal of uncertainty
with the Gulf system but there are no imminent threats to our area
at this point.

&&

.NEAR TERM /THROUGH MONDAY/...
At 430 PM Sunday: An upper ridge was centered near the Delmarva
Peninsula this afternoon, extending inland to the central
appalachians. Meanwhile an upper low associated with a surface
tropical; system was off the SC/GA coasts. By monday the upper ridge
nearly splits in two, with center over KY and NW of Bermuda, while
the upper low reaches the SC/GA coasts.

At the surface, the bulk of low level moisture was located over the
NC mountains and along the NC/SC coasts this afternoon, while drier
air was working its way southwest over the piedmont. The best
chances of convective development will remain across the mountains
but will be sparse even there. Have updated PoP to show this trend
and decrease clouds based on latest sat pix. Model soundings suggest
this activity will diminish early this evening. Although instability
is present on Monday, model soundings suggest significant drying in
the afternoon, ostensibly relate to subsidence on the west side of a
coastal tropical system. This would limit convective chances over
much of our area. Temperatures will run near normal.

&&

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/...
As of 200 PM EDT Sunday, Tropical Depression Eight (or a named
system) will likely be positioned just off the NC Outer Banks
Tuesday morning - situated in a weakness in the upper level ridge
along the East Coast. The main question for our forecast area will
be whether or not any tropical moisture from the system can work
west across the piedmont. Consensus keeps the better moisture
confined to the coast, with very low end precipitation chances
reaching our lower piedmont, and a secondary and better maximum of
PoP over the mountain ridges in scattered diurnal convection.

Falling heights from the north on Wednesday should permit the
coastal tropical circulation to begin moving back out over the open
water. Meanwhile, a surface cold front will slowly approach from the
northwest but remain NW of the area through late day. Again, the
bifurcated PoP forecast will feature slight chance eastern piedmont
PoPs but with the best focus for continued diurnal thunderstorm
chances over the mountains. Temperatures will continue slightly
above climo.

Any development in the Gulf with the current 99L system, and
associated impacts on the western Carolinas and NE GA, should become
much more apparent by Tue/Wed.  No adjustments to sensible weather
from this system will be needed for our area through late Wed at
this point.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
As of 215 PM EDT Sunday, the medium range fcst picks up at 00Z on
Thursday with an upper trof digging down over the Great Lakes and
a very steep upper ridge spreading over the central CONUS. In
addition, a tropical disturbance that is currently located just
north of Cuba is expected to be located off the west coast of
Florida by the start of the medium range. As we move into Friday,
the trof axis will move NE of the fcst area and eventually move
offshore while the upper ridge spreads farther east eventually
encompassing most of the CONUS. At the sfc, a fairly complex
synoptic pattern will likely exist to start the period early
Thursday. The tropical low corresponding to the above mentioned
upper low is expected to be located a couple hundred miles off the
west coast of Florida. The long range models continue to differ
with respect to the strengthening of the system and to a lesser
extent the track, over the next few days. As has been the case
for days now, the ECMWF has a deeper low and moves the system
faster and farther north than the GFS. The CMC is also deeper
than the GFS and moves the low even farther westward and then
inland than the ECMWF. The main discrepancy lies in the strength
of the Canadian sfc high that settles over the Great Lakes on
Thurs and Fri. If the high is strong enough and able to move far
enough south early in the period, it will keep the low from
advancing as far north on Fri and Sat. By Sunday, the models agree
that the high will be sliding off the New England Coast and will
have less of an impact steering the tropical low. As for the
sensible fcst, if the current 12Z GFS solution verifies our CWFA
would remain mostly dry. If the older 00Z ECMWF verifies, we would
see more deep moisture over our SE zones but drier air over NW
half of the CWFA. Only the Canadian solution brings deep tropical
moisture over the entire fcst area, and thus widespread precipitation.
I have opted for a blend of the GFS and ECMWF solutions with solid
chance POPs on Thurs, Fri, and Sat and mostly dry conditions for
Sunday. Temps will start out above climatology and cool to near
or even slightly below climo by the weekend.

&&

.AVIATION /21Z SUNDAY THROUGH FRIDAY/...
At KCLT and elsewhere: Drier air moving in from the northwest will
not be very supportive of afternoon convection today or Monday.
Winds are expected to favor the northeast at foothills sites, and
the north at KAVL. A guidance blend only favors a daybreak vsby
restrictions at KAVL, with IFR there. Guidance does favor a daybreak
cig restriction at KCLT.

Outlook: Ridging will persist across the region into early next
week. Convective chances may be limited by sinking air to the west
of a tropical system at the coast. Patchy fog will be most favored
in mountain valleys.
