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 severe thunderstorm warning; the first came 37 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

Charleston AFB, SC (KCHS), launched 12:00Z, 9.1 hours before the alert went out and 104 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.

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 Wilmington, NC wrote its last area forecast discussion before this severe thunderstorm warning went out at Aug 18, 3:29 PM EDT, 1 hour 34 minutes earlier.

Area forecast discussion, Aug 18, 3:29 PM EDT, 1 hour 34 minutes before

Area Forecast Discussion
National Weather Service Wilmington NC
329 PM EDT THU AUG 18 2016

.SYNOPSIS...
A weak surface trough will drop slowly southeast across the
Carolinas and stall, bringing an increasing chance of showers
and thunderstorms over the next few days. A return to above normal
heat is forecast for the weekend, with heat index values exceeding
100 degrees on Sunday. A cold front will cross the area on Monday,
bringing a refreshing airmass change with cooler and drier weather
following through the middle of next week.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
As of 320 PM Thursday...Local Vad Wind Profile shows a deep WNW
flow aloft at this time, although maximum speeds were only 25
KT in the column. The seaward encroaching storms will edge off
shore while an unworked-over portion of our SC interior appears
set for rumblers and briefly heavy rainfall through afternoon
to early evening. Portion of inland SE NC may not see additional
rainfall through tonight. Convection is expected to gradually
wane in intensity and coverage in early evening. Until then the
weak steering flow will lend to slow moving TSTMS and ponding
water in isolated locations, favored over interior NE SC. The
other hazard remains dangerous cloud to ground lightning.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH SATURDAY NIGHT/...
As of 320 PM Thursday...Main headline features unsettled
conditions and seasonable warmth. A weak trough across the
interior coupled high precipitable water will keep a good chance
of storms while the weak steering flow maintains a threat of
localized flooding and ponding problems. This threat will prevail
both Friday and Saturday. The low level west flow is a little
stronger Saturday which will keep the sea breeze pinned closer to
the coast with a good chance of convection there, and storms will
move a little faster boosting slightly the wind threat.

&&

.LONG TERM /SUNDAY THROUGH THURSDAY/...
As of 300 PM Thursday...One last hot and humid day forecast for
Sunday as ridging aloft combines with Bermuda high pressure offshore.
Temps are expected to rise into the low 90s, which combined with very
high dew point air will create heat index values approaching 105
degrees.Weak impulses in the mid-level flow will tap a very
unstable environment to create scattered tstms on Sunday, with
periods of heavy rain the primary threat due to very high PWATS.
Thereafter, a cold front will move across the region on Monday, and
this front has the potential to bring the first taste of autumn with
it as much cooler and drier weather is forecast for the remainder of
the extended - Tue/Wed/Thu. The GFS/ECM differ in how far south this
front sags and how quickly the cooler air gets into the region, and
although the ECM would bring more significant fall-like weather, the
GFS is preferred with the slower southern push of the front. This is
because of renewed ridging developing behind the cold front's parent
trough, which should slow the boundary to the south before a renewed
push of dry/cool air comes through Wednesday. Either way, the middle
part of next week appears to feature beautiful late-summer weather
with temps below climo and limited precip potential.

One climo note: The ongoing streak at Wilmington of temperatures not
dropping below 70 stands at 53 days (as of the 18th). The current
forecast has that ending on Wednesday, which would end the streak at
58 days - breaking the all-time record by 2 days. Some of the
guidance has the low dropping below 70 on Tuesday morning - if this
occurs we would still break the record, just by 1 day instead.
Current forecast keeps Tuesday morning just above 70 however due to
a bit more of an E/NE wind component off of still very warm ocean
waters.

&&

.AVIATION /20Z THURSDAY THROUGH TUESDAY/...
As of 18Z...Terminals are currently VFR and VFR should continue for
the majority of the TAF valid period. Showers and thunderstorms
should become scattered this afternoon as an impulse aloft acts on
warm, moist low level air.  Expect to see all terminals affected by
convection this afternoon with the exception of LBT which already has
been.  It is possible there could be another round there too so VCTS
has been included at LBT aft 21Z. WSW surface winds will back to the
S-SW this afternoon. Ceilings will remain well above 3k feet outside
of thunderstorm cores. for now...terminals show thunder this
afternoon but it is possible that it could continue into the evening
particularly inland. additionally, a fog threat may develop tonight
depending on where and how much rain falls at or near the terminals.

EXTENDED OUTLOOK...Overall VFR. Scattered mainly afternoon showers
thunderstorms with low confidence for brief IFR conditions. Low
confidence of morning MVFR/IFR due to fog/low ceilings, mainly
inland. SW winds will prevail until Monday when a cold front will
move through and turn surface winds northerly.

&&

.MARINE...
NEAR TERM /THROUGH TONIGHT/...
As of 320 PM Thursday...Seas around 2.5 FT mainly in SSW wind
waves of 1-2 FT and SE-E waves between 6-8 seconds. This regime
will prevail tonight with an uptick in SSW winds and likewise SSW
waves as gusts to 20 KT unfold. TSTMS will impact the waters this
evening and overnight and a radar update in encouraged before
heading out.

SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
As of 320 PM Thursday...Moderate SW winds this period as Bermuda
high pressure remains east of the waters. SW winds 10-15 KT will
gusts to 20 KT at times, including near shore in the afternoon.
TSTMS will be scattered to numerous due to a weak surface trough
just inland from the coast. Seas mainly in the 2-3 foot range
outside of TSTMS will be composed of SSW waves 1-2 ft every 4-5
seconds and Se waves 1-2 ft every 6-8 seconds.

LONG TERM /SUNDAY THROUGH TUESDAY/...
As of 300 PM Thursday...Bermuda ridging will remain the dominant
feature the first half of the extended before a cold front crosses
the waters with a wind shift during Monday. Winds on Sunday will
be SW around 15 kts, and then slowly shift to the NW with
decreasing speeds around the frontal passage on Monday. By
Tuesday, a NE surge will develop behind this front, with wind
speeds increasing once again up towards 15 kts. Seas Monday of
around 2 ft will be bookended both Sunday and Tuesday by 2-4 ft
seas. On Sunday, a SE swell and SW wind wave will comprise the
spectrum, whereas on Tuesday an amplifying E/NE wind wave will be
the dominant wave group.
