The radar
The Greer radar (KGSP), 97 km from the middle of the area, began a volume at 23:57 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 flash flood 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
Greensboro/Hi Pt, NC (KGSO), launched 12:00Z, 12.0 hours before the alert went out and 188 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.

BULLETIN - EAS ACTIVATION REQUESTED
Flash Flood Warning
National Weather Service Greenville-Spartanburg SC
757 PM EDT THU MAY 31 2018
The National Weather Service in Greenville-Spartanburg has issued a
* Flash Flood Warning for...
McDowell County in western North Carolina...
Western Burke County in western North Carolina...
* Until 200 AM EDT Friday.
* At 752 PM EDT, Doppler radar indicated thunderstorms producing
heavy rain approaching McDowell and Burke Counties. Flash flooding
will likely begin shortly.
* Emergency management reported that creeks and streams in the
western parts of the counties remain at bankfull. Isolated slope
failures and mudslides have occurred through the day, even before
a round of rain earlier this evening. Areas at lower elevations
have seen most of the water recede, but with saturated soils, even
as little as a half inch of rain could result in rapid, life-
threatening rises on area creeks and streams.
* Some locations that will experience flooding include...
Morganton, Marion, Glen Alpine, Old Fort, B.R. Parkway-Craggy To
Little Switzerland, Lake James State Park, B.R. Parkway-Little
Switzerland To Linville, South Mountains State Park, Lake James and
Nebo.
Excessive rainfall over the warned area will cause mud slides near
steep terrain. The mud slide can consist of rock, mud, vegetation and
other loose materials.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
Most flood deaths occur in vehicles. Do not attempt to cross
water-covered roadways, bridges, or low-level crossings. Only a few
inches of rapidly flowing water can carry away your vehicle. It is
not worth the risk. Please TURN AROUND, DON'T DROWN.
The additional heavy rain will increase the risk of landslides,
especially in areas where slides have occurred in the past. Be
especially alert if you are near a stream, especially at the base of
a mountain or in a cove. Watch for loose-moving soil and rocks or a
sudden increase in streamflow. Leave the area quickly if this is
observed. When driving along roads where the terrain is steep or
rocky, watch and listen for falling rocks, mud, trees and other
debris.
When it is safe to do so, please report flood waters or landslides
flowing over roads or threatening property to the National Weather
Service by calling toll free, 1, 800, 2 6 7, 8 1 0 1, by posting on
our Facebook page, or via Twitter using hashtag NWSGSP. Your message
should describe the event and the specific location where it
occurred, including roadways, nearby cross streets, stream names and
other landmarks.

Area forecast discussion, May 31, 2:51 PM EDT, 5 hours 6 minutes before
Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
251 PM EDT Thu May 31 2018
.SYNOPSIS...
A moist airmass will persist into Friday, with a couple of
rounds of thunderstorms crossing the region from the west in the
afternoon and evening. Slightly drier air will work in from the west
on Saturday, but with a brief return of moisture by late weekend.
Better drying will arrive behind a passing cold front in the early
to middle part of next week.
&&
.NEAR TERM /THROUGH FRIDAY/...
FLASH FLOOD WATCH FOR THE MOUNTAINS AND NC FOOTHILLS REMAINS IN
EFFECT THROUGH TONIGHT
As of 2pm EDT Thursday: Round of showers and thunderstorms
currently underway with precipitation over much of Western North
Carolina , Northeast GA, and the foothills. Showers will continue
into the evening, moving southeastward across the area. Current
activity is related to upper wave cross the region with some
dynamical forcing. Precipitable water values are down several
tenths of an inch from recent days, but with this upper support,
some heavy rain showers are still possible. This wave is reinforced
by a second wave on Friday. By Friday afternoon, a surface front
related to these upper waves will be come better defined and will
begin moving across the CWA. Surface front and better upper wave
will increase the strength of the wind profile and provide better
dynamical support for showers and thunderstorms Friday afternoon.
Friday showers; however, will be faster moving and will leave behind
less precipitation that what we will see today. With some
improvement in the flooding conditions expected through Friday
morning, a Flash Flood Watch for Friday afternoon/evening does not
seem justified at this point. However, it might be considered if
enough areas get appreciable rainfall this afternoon. The Flash
Flood watch for this afternoon/tonight still looks good, but has
been trimmed 6 hours at the end as shower activity will decline
considerably by early Friday morning.
With some upper support on Friday, both shear and instability
increase, and chances for severe weather go up a notch with the
Friday storms. Deep layer shear improves to 15kt, with CAPE to 1500
j/kg. Shear is still too weak for much of a tornado threat, but
chances for severe outflows and some hail exist. Any strong winds
from storm outflows could cause numerous tree falls as tree roots
have been weakened from recent rains. Following the round of thunder
on Friday, the passage of the front will bring dewpoints and chances
for precipitation down considerably. Dewpoints decline 4 degrees by
Friday night. Temperatures will remain generally warm and humid
through Friday, however.
&&
.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
As of 225 pm Thursday: The transition to a less tropical, more
typical late spring/early summer warm/humid regime will be completed
during the short term. Nevertheless, the pattern will remain quite
active, with a series of short wave troughs and attendant surface
features providing a focus for at least scattered diurnal convective
activity Sat and Sunday. Meanwhile, westerly deep layer flow will
allow for some modified elevated mixed layer air to filter into the
region, with mid-level lapse rates of 6.5-7 C/km progged through the
weekend. This will result in substantial sbCAPE each day, with
maximum afternoon values likely reaching at least 2500 J/kg. Thus,
while there may be less overall coverage of convection, especially
on Saturday, there will be higher potential for strong to severe
updrafts. This will most likely be in the form of pulse storms on
Saturday, when the deep layer shear will remain relatively weak, but
with more of a multicellular (if not something even more organized)
threat on Sunday, as deep layer shear increases to 30 to 40 kts
southeast of a robust short wave trough/upper low moving across the
Great Lakes. Although antecedent hydrologic conditions should
continue to gradually improve, a localized flash flood threat will
continue along the Blue Ridge into the weekend.
&&
.LONG TERM /SUNDAY NIGHT THROUGH WEDNESDAY/...
As of 210 PM Thursday: Much drier air will filter into the region
behind a cold front Monday morning. The GFS is more robust with the
deep 500mb low moving ESE from the Great Lakes on Monday. The EC has
this feature more north and weaker. Both models take this low across
PA and New Jersey Tuesday and Tuesday night and enough shortwave
energy should affect the NC Mountains and somewhat less effects for
the foothills and piedmont. Certainly needs slight to low chance
POPs as it passes. Drier air again returns after the low moves off
the East Coast. A weak backdoor cold front drops down Wednesday or
Thursday but currently not expected to have much affect on our
weather. Going with a dry forecast Wednesday and Thursday.
Will need to watch the weak low over the NE Gulf and how it
influences our weather mid to late week. Temperatures will be near
or even a little below normal through the extended.
&&
.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
At KCLT and elsewhere: Generally low cloud decks have kept many
stations at MVFR today, with some possible improvement as the
afternoon progresses. Thunderstorms this afternoon will move across
the area from the northwest to southeast through 2z. Storms will be
scattered, but some stations will have heavy rain, thunder, and
reduced visibility and ceilings as temporary conditions at times.
Included some fog overnight at KAVL, but most stations are not
expected to have problems as boundary layer moisture is gradually
declining. Another round of thunderstorms is possible Friday
afternoon which will begin to affect TAF sites around 18Z. These
storms will be occurring along and ahead of a front that will also
veer surface winds to be more southwesterly to westerly on Friday.
Outlook: Slightly drier air will filter into the area for the end of
the work week. However, scattered afternoon/evening showers and
thunderstorms, along with possible morning fog at a few locations
and/or low cigs are possible each day through early next week.
