Local storm reports filed while the alert was in force, from inside its polygon or its counties.
Did it verify
Verified. The Iowa Environmental Mesonet's Cow matched one storm report to this flash flood warning; the first came 106 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.
The nearest sounding before it
Greensboro/Hi Pt, NC (KGSO), launched 12:00Z, 10.3 hours before the alert went out and 179 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.

HGWhat forecasters said that day
The local office's own words before this flash flood 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 flash flood warning went out at Jul 27, 4:59 PM EDT, 1 hour 20 minutes earlier.
Area forecast discussion, Jul 27, 4:59 PM EDT, 1 hour 20 minutes before
Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
459 PM EDT WED JUL 27 2016
.SYNOPSIS...
Broad surface high pressure will linger over the Southeast, before
sliding offshore as a surface low develops and moves northeast
across the Midwest and Great Lakes regions. A surface front will
remain off to our north and linger within a region between the Ohio
Valley, lower Great Lakes, and Mid-Atlantic regions. This front may
finally move into our area over the weekend.
&&
.NEAR TERM /THROUGH THURSDAY/...
2100 UTC Update: Sky cover was updated from visible satellite
imagery. Pops were updated based on radar trends, resulting in a
decrease east of the mountains, and an increase on the northern and
southern mountains.
Previous Discussion: Convection is taking it's time developing
across the CWFA...mainly confined across the nrn zones near a sfc
bndry and some periodic pop ups across the ridgetops. The lower
atmos has mixed out a little more than expected across the nrn
Upstate and srn NC Piedmont. Td/s are in the m60s leading to a
SBCAPE minima and shallow Cu development. The best activity area
this afternoon/evening will be across the nrn zones and perhaps
across the nrn SRV where higher end CAPE is developing.
The overnight will see gradual moist adv from the SW due to a
subtrop disturbance being lifted north toward the TN valley. Most of
the heavy precip will be aligned south and west of the FA...but the
NC mtn spine counties shud see enhanced -shra/tstm activity
lingering through daybreak. Some isol activity is also possible
across the nrn fthills and nc piedmont with the llvl bndry remaining
fairly stationary.
The fcst for Thu is a bit tricky compared to the previous few days
as mid and upper level forcing will increase somewhat as a broad h5
trof moves across the lower Midwest and an h85 low associated with
the aforementioned ST disturbance continues to advance closer to the
wrn zones. This will increase llvl shear values to arnd 25kts or so
during the afternoon...and along with modest SBCAPE values...some
storms could become loosely organized and produce relatively long
lived cold pools...esp across the wrn zones. This would produce
more of a straight line wind threat as opposed to the localized
microburst activity seen lately. Max temps will be a couple degrees
cooler tomorrow and shud preclude another heat adv issuance based on
similar Td/s across the area.
&&
.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/...
As of 200 PM EDT Wednesday: At the start of the period, subtropical
ridging will remain in place over the Southeast and portions of the
Western Atlantic, with upper trough extending down the Mississippi
Valley. The initial shortwave will lift northeast on Friday as mean
troughiness continues across the east, with a secondary shortwave
pushes out of the Plains for the latter half of the period. With the
general southwest flow aloft over the Southern Appalachians, plume
of tropical moisture that moved onshore over the Lower Mississippi
yesterday will stretch northeast up the Ohio Valley, over the upper
ridge. Attendant surface front will slowly work its way toward the
Appalachians but with a continued lee trough across the NC
foothills/Piedmont serving as a focusing mechanism for afternoon
convective development. The secondary wave and slug of moisture
pushes across the Tennessee Valley Saturday as the mean trough
slowly pushes east. Fairly good agreement in synoptic fields on the
operational models, but as usual some differences in details and
sensible weather impacts, with the GFS remaining slightly wetter
than the ECMWF.
Overall, best deep-layer moisture will remain to our west with the
front but with the addition of synoptic lift from the broadening
wave, should see a slightly higher than climo trend to pops through
the short term. Instability looks fairly typical of summer, with
mixing across the Piedmont contributing to slightly lower CAPE
values than those across the mountains. Low-level lapse rates will
continue to support an isolated wet microburst or two, with daytime
high temperatures hovering just slightly above normal, and overnight
lows about a category above.
&&
.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
As of 230 PM EDT Wednesday: Aforementioned slug of moisture
associated with secondary shortwave will push across the Southern
Appalachians at the start of the extended period, with the longwave
trough axis continuing to slowly move east and centered over our
area around the start of the work week. Upper ridge strengthening
across the Plains will ridge northeast as the the trough becomes
increasingly positively-tilted, remaining stalled over the area
generally through the period. Corresponding surface trough will
enhance (or possibly itself be enhanced by...chicken-or-egg thing
here) the lee trough that has been in place the past couple of days.
This will keep a higher-than-climo diurnal trend in convection
across the region, with continued support of isolated to widely
scattered strong to severe storms in the form of wet microbursts.
Temperatures trend more toward climo with expected increases in
cloud cover and convection, but will continue to see some variation
each day.
Because the GFS is showing it approaching the NC coast very late in
the period, will note that invest of a disturbance off the coast of
Africa has been given a 40% chance of tropical cyclone formation
through 5 days. Model solutions vary *widely* as this pushes WNW
toward the Leeward/Windward Islands - this is way too far out to
make any prognostications at this time!
&&
.AVIATION /21Z WEDNESDAY THROUGH MONDAY/...
At KCLT and Elsewhere: Another day of afternoon convec prompting
TEMPO tstms across all sites except KAND. Prominant bndry just north
of the KHKY will keep cloud cover and precip activity lingering
through the overnight...while increasing shear and moist adv across
the mtns will keep a prob30 mention at KAVL through the early
morning. KAVL could see some morning FG...but likely less dense than
this morning due to increased sfc winds. Moderate gusty conds will
develop toward the end of the TAF period across most
locales...especially the Upstate and NC Piedmont.
Outlook: A plume of deep moisture will gradually build across the
western Carolinas and NE GA through the late week. SCT SHRA and
TSRA will be possible each afternoon and evening, coverage the
greatest across the mtns. Pre dawn fog and low clouds will be
possible over areas of recent rainfall.
