816 pm edt Tue aug 21 2018

Synopsis
Showers and thunderstorms will be possible through early
Wednesday ahead of an approaching cold front. The strong august
front will clear the coast before daybreak Thursday, bringing a
drying and cooling trend to the region Thursday and Friday.

Canadian high pressure extending along the interior of the
carolinas, may help bring in atlantic moisture and light rain
showers to the coast next weekend.

Near term through Wednesday
As of 815 pm Tuesday... The forecast area was largely void of
precip until late afternoon, when a few showers and
thunderstormsmanaged to fire up in the vicinity of the sea
breeze boundary. This activity has diminished with the loss of
daytime heating, however there will be potential for additional
convection this evening and overnight, which will be associated
with a mid- level shortwave currently moving across the western
carolinas. Despite loss of heating, the airmass will remain
unstable overnight, and current radar trends bring ongoing
storms into western darlington and marlboro counties by 02z.

Will maintain low chance pops in the forecast overnight as the
shortwave traverses cwa, with favored areas being north of a
florence to whiteville line. The hrrr has also maintained some
consistency with some additional flare up possible after 09z in
the vicinity of CAPE fear.

Shortwave pushes off the coast Wed morning with post wave
subsidence and mid-level drying likely bringing an end to any
overnight convection. Cold front will approach from the
northwest as 5h trough moves into the area. West to northwest
flow aloft will limit moisture return ahead of the front which
will have a negative impact on diurnal convection. Best chances
will again be along the sea breeze, especially at the brunswick
inflection point, during the afternoon hours. Highs Wed will be
near to slightly above climo with most areas in the upper 80s to
lower 90s.

Short term Wednesday night through Thursday night
As of 3 pm Tuesday... Surface low pressure moving through the
canadian maritime provinces and high pressure advancing eastward
through the ohio valley will together push a cold front through
the eastern carolinas Wednesday night. This is our first cold
front of the approaching fall season and promises to bring at
least 36 hours of drier, canadian air southward into the
carolinas.

Before the front gets here Wednesday evening, an unstable airmass
could still produce scattered showers and thunderstorms, especially
near the coast. Convective activity should end as the front arrives
during the late evening hours. An approaching upper disturbance and
right-entrance region of a 250 mb jet will probably arrive too late
to do more than produce some post-frontal mid-level clouds
around 7000 feet up, visible on GFS nam forecast soundings.

850 mb temps have been averaging +18c for the past couple of weeks,
but should cool to around +15c behind the front Thursday. Even with
plenty of sunshine highs should only reach the mid 80s, 3-5 degrees
below normal. Dewpoints in the 60s (or even upper 50s west of i-95)
should yield apparent temperatures not significantly different than
the actual air temperatures! Mainly clear skies Thursday night and
good radiational cooling conditions are expected as the surface high
moves across the mid-atlantic states. Inland temperatures should
fall into the 60-65 degree range, however northeasterly winds near
the coast will keep air temps warmer since water temps are still in
the 80s.

Long term Friday through Tuesday
As of 3 pm Monday... A rather flat pattern aloft will be in place at
the onset of the long term period as h5 subtropical high continues
across tx and ridges eastward across the deep south. During this
time the main shortwave energy will remain north of the area as it
transits the great lakes region Friday into Saturday, then new
england during Sunday. Meanwhile at the surface Friday the forecast
area will be in the post-frontal regime with high pressure ridging
across the carolinas from the mid-atlantic states. A trough (the old
front) will drift back toward the coast this weekend but is progged
to become absorbed in the larger scale flow from high pressure
farther offshore. The chance of showers tstms will be very low
Friday Saturday in the stable drier conditions behind the old front.

Some instability is shown to return to the area during Sunday with
only low pops needed at this time. The sea breeze is expected to
become more active mon-tue time frame as precipitable water could
approach 2 inches again. Mex high low temperatures appear
reasonable, thus did not stray too far from them.

Aviation 00z Wednesday through Sunday
As of 00z... Convection near the coast will keep vcsh through 03z.

Convection in western south carolina will push into our western
counties by 02z, weakening as it does so. Little to no fog is
expected overnight. There will be enough instability and lift to
kick off some weak convection at the coastal terminals toward
morning. Wednesday, showers push off the coast and take a lot of the
deep moisture with them. The atmosphere may have time to reload in
the afternoon, but expect only isolated convection due to lack of
mid and upper level moisture. Southwest flow through the period.

Extended outlook... A frontal passage is expected early Thursday with
a drying trend, andVFR conditions Thursday and Friday, with ne
surface winds. MVFR ceilings possible Saturday at coastal terminals
as atlantic moisture and -ra moves ashore.

Marine
Near term through Wednesday ...

as of 815 pm Tuesday... A few showers and isolated thunderstorms
have quickly dissipated as they moved off the coast late this
afternoon. Not expecting any additional convection over the
waters until perhaps 3-6 am, when a shortwave will move off the
coast. Otherwise, the period will be dominated by southwest
flow with combination of nocturnal jet and tightening gradient
maintaining winds in a 15 to 20 kt range overnight, with a few
gusts to 25 kt. Speeds will remain 15 to 20 kt on Wed as a cold
front slowly approaches from the northwest. Seas of 2 to 4 ft
tonight will build to 3 to 4 ft on Wed and may reach 5 ft at
times in the vicinity of frying pan shoals.

Short term Wednesday night through Thursday night ...

as of 3 pm Tuesday... The first canadian cold front of the
approaching fall season will move through the coastal waters and
offshore Wednesday night. Average model timing of the frontal
passage has sped up a few hours from yesterday's model runs, and
it now appears the front should push offshore between 2-4 am
Thursday morning. Behind this front, high pressure over the ohio
valley will build eastward, pushing a drier canadian airmass
into the area on breezy north and northeast winds.

Prefrontal SW winds around 15 kt should shift to the north late
Wednesday night. Winds will diminish Thursday afternoon due mainly
to diurnal effects weakening the pressure gradient along the coast,
but rising pressures inland Thursday night due to boundary layer
cooling and the approach of the synoptic high should increase ne
winds to 15-20 kt. Duration of winds will hopefully keep seas below
6 feet, although wave conditions should become quite choppy away
from shore as the fetch will be become long in a NE wind.

Long term Friday through Sunday ...

as of 3 pm Monday... High pressure will ridge across the carolinas
from the mid-atlantic region in the post-frontal regime. The flow
will be from the northeast through Friday night. A trough east of
the waters Saturday will weaken as it moves toward the coast.

Thus after a period of northeast winds the flow will veer to an
east-southeast direction, especially once the trough dissipates.

Speeds will be highest during Friday in the northeast fetch, but
conditions while not optimal, should remain below small craft
thresholds. Otherwise, choppy seas in the northeast fetch Friday
will gradually subside through Saturday, but more-so during
Sunday.
