Special Weather Statement, NWS Wilmington, NC

Area Forecast Discussion
National Weather Service Wilmington NC
1036 PM EDT TUE AUG 2 2016

.SYNOPSIS...
Thunderstorms with very heavy rain will continue well into the
night as a cold front enters the area and stalls. Seasonable to
slightly warm weather is expected over the weekend as are
scattered thunderstorms. Another cold front may stall in the area
Sunday.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
As of 10 PM Tuesday...Numerous showers and thunderstorms were
slipping S and SE through the forecast area ahead of a weak cold
front and approaching mid-level shortwave. We expect these heavy
rain producing thunderstorms will be with us well into the night.

The column remains deeply moist at around 2.2 inches of P/W. The
main risk from these slow moving thunderstorms will be very heavy
rain capable of causing significant ponding in low-lying and poor
drainage areas. Where thunderstorms train for a prolonged period
of time, flooding may become more serious. We have added heavy
rain verbiage to the gridded forecast. Frequent lightning is
expected to continue into the overnight hours.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH THURSDAY NIGHT/...
As of 3 PM Tuesday...A cold front will drop over the eastern
Carolinas, stalling in the Cape Fear region early on Wednesday.
Ample moisture will combine with foci in the form of the frontal
boundry, outflow boundries and a weak sea breeze circulation to
bring at least scattered convection each day, primarily in the
afternoons and evenings. Temperatures will be quite seasonal on both
days.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
As of 3 PM Tuesday...A front will be stalled along the coast and
weakening on Friday. Deepest moisture should be pooled near the
boundary and so rain chances a little higher there than inland. Lift
will be provided by both the front and a weak upper vort max. There
should be a bit more than the normal amount of cloud cover for
August but temperatures will be near normal. Piedmont trough
develops Saturday but mid level flow is out of the north, which is
not very favorable for meaningful rain chances though series of weak
upper level impulses will mean rain chances at least as high as
Friday. Sunday will bring scattered convection as well as a front
enters the area and stalls. Areas near and east of the front may
have better chances so possibly similar to Friday depending on where
the boundary stalls. The latter part of the extended is muddled by
the uncertainty regarding this front. It may sink well to our south
and allow for a cooldown and nearly rain-free forecast. Not ready to
buy that solution just yet and so will keep near climo temps and
POPs at this time.

&&

.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
As of 00Z...Fairly widespread convection to the north and west of
the CWA at this time, associated with a frontal boundary that will
slowly drift southward overnight. Think we could see a fair amount
of convection through most of the overnight hours, dropping south
along with the front and the steering flow. LBT and ILM stand the
best chance for thunder, as the HRRR model has been fairly
consistent with this scenario. Lesser chances for convection at
FLO and the Myrtles. Some light fog is possible at terminals that
received convection. Winds will be predominately east northeast at
the northern terminals in the morning, as the front should be
south of them. Winds will shift to the southeast at all terminals
by midday as the front tries to wave back northward.

EXTENDED OUTLOOK...Isolated to scattered afternoon
and evening convection each day may result in localized MVFR/IFR
conditions. Each morning may also observe brief MVFR/IFR from fog
and/or low ceilings.

&&

.MARINE...
NEAR TERM /through tonight/...
As of 10 PM Tuesday...Strong thunderstorms will continue to drop
south across the waters overnight. The Bermuda High over the
western Atlantic will keep winds primarily from the SW at 15 to 20
kt. Seas will be 2 to 4 ft. A cold front will drop south towards
the waters through the period and will be positioned north of Cape
Fear by daybreak.

SHORT TERM /Wednesday through Thursday night/...
As of 3 PM Tuesday...A cold front will drop over the waters early
on Wednesday, then will remain stalled over the forecast area
through the remainder of the short term. As the front will be weak
with little in the way of gradient we expect winds to stay on the
modest side, generally 10 to 15 kts, with seas in the 3 ft range.
Expect gusts up around 20 kts each day.

LONG TERM /FRIDAY THROUGH SUNDAY/...
As of 3 PM Tuesday...Friday may start off with light and variable
winds due to a front stalled in the area. This boundary will
likely weaken and/or lift northward allowing for a SW direction to
become predominant. Piedmont trough develops Saturday while
Atlantic high pressure holds. Winds stay SW but should increase a
category in strength allowing for a return of 4 ft waves away from
shore. A front enters the area again on Sunday and stalls. There
may be some uncertainty in wind direction forecast but wind speed
and wave height should both decrease some.
