What forecasters said that day

The local office's own words before this flash flood watch 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 flash flood watch went out at Jul 23, 2:57 PM EDT, 39 minutes earlier.

Area forecast discussion, Jul 23, 2:57 PM EDT, 39 minutes before
Area Forecast Discussion
National Weather Service Wilmington NC
257 PM EDT Mon Jul 23 2018

.SYNOPSIS...
Low pressure will develop across Georgia later today, while
offshore a large ridge of high pressure will cover the
northwestern Atlantic. Between these two systems tropical
moisture will be pulled northward, bringing several days of
showers and storms to the eastern Carolinas. Heavy rainfall is
possible, particularly near the coast. The low should weaken
late Wednesday and Thursday with showers and storms becoming
more scattered in coverage through early next week.

&&

.NEAR TERM /THROUGH TUESDAY/...
As of 300 PM Monday...Satellite imagery shows a moisture laden deep
southerly flow although not purely tropical hence the abundance of
lightning. Guidance is in general agreement on at least a couple of
rounds of heavy rain moving across the Cape Fear region tonight and
according to some guidance into the day Tuesday. The NAM is more
aggressive maintaining the heavy rain through much of the day
Tuesday while the GFS has it mostly tonight. Long story short, with
at least some consensus on timing and placement, will go ahead and
hoist what has been an almost inevitable Flash Flood Watch for the
North Carolina coastal counties and Horry county in South Carolina.
Through the near term time frame we are expecting 2-4 inches of rain
highest amounts across Pender County. Horry County is a little iffy
but if the heavy rain axis wobbles just a few miles to the southwest
they would certainly see an abundance of rain. No changes to the
temperature forecast.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY NIGHT/...
As of 300 PM Monday...Mid level trough to our west opens up Tuesday
night. Oddly enough even though this means the feature is weakening
it still allows for height falls and PVA locally from points west.
In such an otherwise stalled pattern of deep layer southerly flow
and copious moisture this is just the triggering mechanism for heavy
rainfall that seemed might be hard-pressed to materialize
previously. As this happens the front will be stalled very near to
our western counties. This boundary will represent the western edge
of the very deep moisture and so there will be a west-east gradient
in QPF; likely a significant one.  Heading into Wednesday morning
before precipitation intensity precipitation totals should range from
1-2" inland to 2-4" coastal SC and 3-5" coastal NC. Flood Watches
hoisted by near term forecast extended into the short term and may
even need to be extended by later shifts.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...
As of 300 PM Monday...Overall troughiness at H5 remains over the
area through the period but does weaken with time.  At the surface,
a frontal boundary will also remain to the north through the period
as deep muggy air mass remains in place too.  These ingredients will
allow for scattered storms through the period though they should be
more diurnally driven than in recent days.  Temperatures will be
seasonal with maximums mainly in the upper 80s to lower 90s and lows
in the low to mid 70s.

&&

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
As of 18Z...Expect mainly VFR conditions this afternoon other
than an hour or two of MVFR in LBT and CRE where convection is
ongoing or approaching. Guidance is in general agreement in an
elongated area of heavy rain and or thunderstorms traversing
the coast of North Carolina tonight and extending into Tuesday.
Wilmington will take brunt of this activity with an extended
period of MVFR conditions. North Myrtle beach will get clipped
while the other stations may be mostly spared with mostly early
morning stratus or fog.

Extended Outlook...Occasional MVFR to IFR conditions due to
scattered SHRA and TSRA through Thursday.

&&

.MARINE...
NEAR TERM /THROUGH TUESDAY/...
As of 300 PM Monday...Winds and seas just about in small craft
criteria where they will remain for some time. Current winds of 15-
20 knots from the southeast will increase later this evening to 20-
25 knots and basically remain there through the day Tuesday.
Significant seas are now near five feet in some places and will top
out at 6-8 feet later Tuesday.

SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY NIGHT/...
As of 300 PM Monday...SCA for most of the period. Deep layer
southerly flow in place through the period. And although south to
southwesterly flow is not uncommon this time of year when the
Bermuda High is in place this is a different setup. The 'normal'
Bermuda High is displaced very much eastward of its normal position
allowing for a larger and more broad fetch into the Southeastern
U.S. Much of the resulting larger period swells will remain to our
east but 6ft advisory-worthy waves will likely be observed along the
outer portions of the 20nm zones for most if not all of the entire
period. The exception may be SC waters late in the period where they
drop out.

LONG TERM /THURSDAY THROUGH SATURDAY/...
As of 300 PM Monday...S to SW winds of 15 KT or less are expected
through the period.  Seas of 3 to 5 FT early Thursday will diminish
to 2 to 3 FT by Saturday afternoon with 4 footers possible at 20 NM
northern waters.
