The radar

The Greer radar (KGSP), 65 km from the middle of the area, began a volume at 05:00 UTC, the scan nearest the moment this went out.

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.

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 Apr 5, 10:20 PM EDT, 2 hours 40 minutes earlier.

Area forecast discussion, Apr 5, 10:20 PM EDT, 2 hours 40 minutes before
Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
1020 PM EDT Wed Apr 5 2017

.SYNOPSIS...
A strong cold front crosses our region tonight and moves
off the East Coast on Thursday.  Expect very windy
conditions Thursday into Friday. Temperatures will be much below
normal Thursday into the start of the weekend, then milder
temperatures return into the first half of next week.

&&

.NEAR TERM /THROUGH THURSDAY/...
As of 1000 PM: We remain within the cool airmass created by
in-situ cold air damming. Therefore sfc based parcels are still
stable and most likely will remain so through the remainder of
the evening. Two separate lines of convective activity are present
over East TN and central GA, slowly moving into the CWFA over the
next hour or so. The HRRR has generally indicated this activity
surviving despite the loss of SBCAPE. Aloft, we still anticipate
destabilization occurring as a deep upper trough translates overhead
later tonight. It is still expected that a band of strong tstms
will accompany or precede the front across the area, though they
are expected to remain elevated. Effective shear should be enough
to support supercells and threats of damaging wind and hail, though
tornadoes no longer appear to be the primary threat--assuming the
wedge does not erode. RAP progs of sfc theta-E continue to indicate
the wedge front will retreat up into the Piedmont overnight,
though those progs are a bit overdone at the current time,
and with WAA ongoing aloft, erosion is unlikely. SPC downgraded
nearly all of our area to Slight Risk on the D1 evening update,
which seems reasonable. Revised PoPs focus the chances closer to
the convective lines as they pass through overnight.

A strong ulvl low builds in quickly aft the squall line bringing a
good amount of llvl caa while the sfc p/grad increases sigfnt/ly.
Soundings show shallow mixing across the mtns to arnd 50 kts and 40
kts or so non/mtns aft 12z Thu and persisting thru midnight Fri.
So...will issue a HW.W for most mtns/fthills and HW.Y across
non/mtns. Northwest flow snowfall will begin during the day,
perhaps just as flurries until afternoon when profiles cool and
ice crystal growth increases. Mins shud be right arnd normal while
max temps will remain in the u50s non/mtns and L50s mtn valleys.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/...
As of 2pm Wednesday:  Main cold front will be well east of area and
off the coast by Thursday evening with some rain/snow showers
continuing with northwesterly upslope enhancement over the Southern
Appalachians. Showers over the mountains gradually trail-off through
Friday as dry advection proceeds.  Snow totals are not expected to
be significant, except at the highest elevations where several
inches or more may occur. Main issue Thursday night/Friday will be
wind potential. Powerful surface low tracks towards the Eastern
Great Lakes with 850mb flow Thursday evening over the GSP area of 40
kts with enhancement over the mountains to 50 kts. Diurnal mixing
under clear skies should give a surface wind reflection of some
concern over all of the area, with the strongest winds and gusts
over the elevated terrain. Winds continues all day on Thursday and
will begin to trail-off late Friday morning, with some elevated wind
potential through Saturday morning. Current high wind watch matches
area of expected strongest wind gusts well.

Skies will be clearing Thursday night/Friday with cold advection
keeping highs on Friday 10 to 15 degrees below seasonal normal, and
the coldest temperatures in the forecast Saturday morning, with a
freeze or frost likely in the mountains and foothills of Western
North Carolina, though continued wind and dry RH will mute the frost
possibility in areas not expecting 2m temps below freezing.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
As of 3pm Wednesday:  From Saturday evening through Tuesday, weather
pattern goes through a transition from northwesterly flow behind
departing trough to 500mb ridging, followed by the next upstream
system which may bring some showers by next Wednesday.  Most of the
extended forecast will be clear and dry with seasonally normal to 5
degrees above normal temperatures.  EC generally agrees with
quiescent forecast Sunday through Tuesday, with a better
chance for precip by Wednesday afternoon.

&&

.AVIATION /03Z THURSDAY THROUGH MONDAY/...
At KCLT and Elsewhere: A shallow and stable wedge airmass remains
over the western Carolinas, encompassing all terminals. Moisture
trapped within this airmass should permit widespread low MVFR to
IFR cigs developing this evening. Relatively low-impact SHRA/TSRA
could develop as well. Overnight, however, a cold front will sweep
through. While that front is expected to scour out the restrictions,
strong TSRA are expected to develop along it as both midlevel
moisture advection and lapse rates increase over the wedge. Though
most likely these storms will remain elevated, isolated damaging
winds and hail will be possible. TEMPOs reflect the expected timing
of the frontally driven TS. Winds shift to NW behind the front at
KAVL, but remain generally S of W elsewhere. Expect strong gusts
to develop by late morning and continue into Friday. At KCLT,
westerly crosswind issues are likely late in the period.

Outlook: Winds will remain very gusty thru Friday. Much colder
air will continue to spill in behind the front, and may lead
to some frost formation in spots Fri morning and especially Sat
morning. VFR conditions should last into Monday.
