Did it verify
Verified. The Iowa Environmental Mesonet's Cow matched 2 storm reports to this flash flood warning; the first came 53 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 00:00Z, 2.1 hours before the alert went out and 68 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.

CARROLLWhat 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 3, 8:20 PM EDT, 1 hour 47 minutes earlier.
Area forecast discussion, Jul 3, 8:20 PM EDT, 1 hour 47 minutes before
Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
820 PM EDT Mon Jul 3 2017
.SYNOPSIS...
High pressure will remain centered over the western Atlantic
while a broad upper level trough persists over the eastern part
of the nation for the better part of this week. A weak cold front
will linger over the region through midweek, helping to focus the
development of showers and thunderstorms. An upper level disturbance
later in the week will initiate pattern change, leading to drier
and somewhat cooler conditions late in the weekend.
&&
.NEAR TERM /THROUGH TUESDAY/...
As of 805 PM EDT: Outflows intersecting along and near the I-85
corridor this evening have given rise to decent coverage of very
heavy rain producing thunderstorms in this area. This activity
should wane through late evening as daytime instability is gradually
lost. Until then, localized flooding will remain possible given the
slow storm movement and well above climo precipitable water values
and deep warm cloud layers.
Otherwise, the general pattern does not change much over the next 36
hours. The main feature of interest is a better-defined shortwave
currently over western TN that will approach the area overnight,
with most of the energy passing by the GSP CWA to the north. This
feature will keep a good chance for afternoon thunderstorms going
again for Tuesday. Temperatures will remain warm and humid with lows
a little above normal and highs near normal.
&&
.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
As of 200 PM Monday: Short wave ridging aloft will gradually develop
over the region during the short term, while weak E/W-oriented
surface boundary and lee side/thermal troughs will linger through at
least Wed. These features will provide additional focus for
development of scattered afternoon/evening showers and storms (in
addition to the usual ridge top convergence/differential heating
effects) on Wed and Thu.
By the end of Thursday, an anomalously strong short wave trough is
forecast to be moving across the TN and Ohio Valleys. Although model
solutions offer slight variations in location/timing, it would
appear that any forcing associated with this feature would most
likely impact the forecast area well after peak heating Thu night.
However, strengthening wind fields aloft will result in improving
shear profiles, which could support some low-end organization of
convective clusters, and severe weather potential slightly higher
than the run-of-the-mill early summer pulse activity. Temps are
expected to remain near to slightly above climo through the period.
&&
.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
As of 210 PM Monday: Low-amplitude long wave troughing will become
established across the East early in the medium range, and persist
through the period. Transitory short wave troughs passing near the
forecast area and attendant weak frontal passages are anticipated
Friday, and again in the Sunday/Monday time frame. These days are
therefore expected to see some degree of enhancement of diurnal
convective chances. In fact, timing of the initial short wave (Thu
night/early Friday) and attendant establishment of a LLJ Thu night
may allow convection to linger well beyond the typical diurnal
cycle. Otherwise, wind profiles should remain a bit stronger than
typical for the time of year, so the potential for low-end
organization of convection will persist each afternoon. Temps will
generally remain around normal through the period.
&&
.AVIATION /01Z TUESDAY THROUGH SATURDAY/...
At KCLT: Outflows have generally moved south of the airfield, but
with some backbuilding exhibited on radar over the airport. This
will keep TEMPO TSRA in the forecast through 02Z with showers likely
lingering until 05Z. There is some potential for restrictions in the
form of low clouds or fog to form given all of the surface moisture
following the heavy rainfall. This will need to be closely monitored
but will keep conditions VFR for now. Anticipate a repeat on
Tuesday afternoon, with building daytime instability followed by
outflow and shortwave driven convection leading to scattered
thunderstorm coverage or better once again. Winds will be gusty near
thunderstorms.
Elsewhere: Residual evening convection on outflows will continue
from mainly KGMU to KGSP early this evening before generally
diminishing in coverage overnight. There remains some potential for
overnight convection to return from the west with the deamplifying
wave moving east over TN, but confidence in any precip at the
mountain and foothills airports is too low to mention overnight.
Anticipate mountain valley fog and low cloud development once again,
and restrictions are quite possible at the foothills given all the
heavy rainfall. Will limit overnight foothills IFR fog and MVFR cigs
to KHKY, while KAVL should be solidly IFR (or worse.) Anticipate
light, generally south to southwest winds returning Tuesday, with
gusts possible near thunderstorms as coverage builds once again
through the afternoon hours.
Outlook: Moist and unsettled weather will continue through the week.
Nocturnal restrictions can be expected in locations receiving heavy
rainfall.
