Did it verify

Verified. The Iowa Environmental Mesonet's Cow matched one storm report to this severe thunderstorm warning; the first came 17 minutes after it went out.

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 Jun 3, 8:16 PM EDT, 9 minutes earlier.

Area forecast discussion, Jun 3, 8:16 PM EDT, 9 minutes before
Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
816 PM EDT Sun Jun 3 2018

.SYNOPSIS...
A well-deserved drier and seasonably warm airmass arrives to begin
the work week.  Only isolated showers and thunderstorms are expected
on Wednesday as a cold front settles into the area from the north.
Drier and seasonable conditions return for Thursday behind the
front before temperatures, humidity, and chances for showers and
thunderstorms increase Friday through Sunday as another cold front
approaches the region.

&&

.NEAR TERM /THROUGH MONDAY/...
As of 755 PM EDT Sunday: A strong cluster of thunderstorms is about
to move over the CLT Metro Area with very strong winds and large hail
expected. By 02z or so, this activity should be moving SE of the CWFA.
Otherwise, the cold front will push SE of the area later tonight,
allowing drier air and NLY low-lvl flow to spread over the fcst area
as sfc high pressure builds from the west to start the work week.
We expect Monday will be the first rain-free day that we've seen in
awhile across the area with plenty of sunshine and temperatures around
to just above normal.

&&

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/...
As of 230 pm Sunday: Dry and comparatively cool weather is expected
to continue through the first half of the short term, as an upper
trough axis persists along the East Coast. A weak boundary dropping
into the area from the north on Wednesday may provide a focus for
some isolated diurnal convection, although guidance is in rather
good agreement that moisture and instability will be difficult to
come by. Temps will be near to slightly below normal through Tue
night, warming to slightly above normal Wed afternoon.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
As of 245 PM Sunday: By Wednesday evening, the longwave trough
axis will be east of the region with the post-frontal surface high
pressure center moving off the Mid-Atlantic coastline.  The surface
ridge axis will settle across the area into Thursday while heights
gradually build aloft as the Southern Plains heat ridge slowly
builds eastward.  Weak low-level flow and the upper-level ridge axis
overhead should work to limit convection on Thursday, and while the
official forecast keeps the area completely dry per the ECMWF and
Canadian solutions, the GFS is a little faster in veering surface
winds SEly and advecting enough flow and moisture to trigger some
afternoon convection.  Nevertheless, high temperatures are expected
to near normal on Thursday before the airmass begins to modify as
the upper-level ridge axis strengthens and southerly flow returns.
This should allow isolated to widely scattered diurnal convection
to return for Friday afternoon as a strong shortwave drops into
the Midwest embedded within the NW flow aloft.  The associated
cold front will sag into the Ohio Valley on Saturday as a repeat
convective performance is expected across the area; however,
by Sunday, moisture pooling ahead of the front combined with the
proximity of the front and aforementioned shortwave energy will
bring better chances for showers and thunderstorms across the
region.  At this time there is decent model agreement on dropping
the front into the area from north to south near the end of the
period or Monday morning.  In the meantime, given the pattern,
high temperatures will be slightly above normal for the weekend
with increasing humidity.  As dewpoints approach 70 degrees,
low temperatures, therefore, will become somewhat uncomfortable
Friday night through Sunday night.

&&

.AVIATION /00Z MONDAY THROUGH FRIDAY/...
At KCLT and elsewhere: VFR conditions should prevail thru the 00z
TAF period with the exception of a large thunderstorm that is about
to impact KCLT. I have a TEMPO for the site for the first hour of
the period that includes brief IFR visby and very strong wind gusts.
The convection should be SE of the airport after 01z. Otherwise,
convective activity should be winding down as the cold front moves
SE of the area over the next several hours and drier air finally works
its way over the area. Winds will become NWLY later tonight and remain
NWLY to NLY thru tomorrow. With elevated boundary layer winds and
drier dewpts spreading over the region, I don't anticipate any fog
development overnight.

Outlook: Expect VFR conditions thru midweek with increasing chances
for showers and thunderstorms towards the end of the week.
