Synopsis
A weak frontal boundary will drop through the area this evening
and overnight. High pressure will settle in behind this feature
much of the week, with an increasingly warm airmass spreading
over the carolinas Friday into early next week.

Near term through Wednesday night
As of 930 pm Tuesday... High pressure is presently sinking
southward over the SE corner of nc this evening, with only the
echoes of a sea breeze boundary, and leading edge of high
pressure giving off returns from the 88-delta. No mentionable
pop values overnight planned as drier air works in, and
convergence weakens along a southward moving surface boundary.

'andrea' downgraded, lost her name as a remnant low, but a
slight uptick in SE swell Wednesday looks reasonable, but only
a foot or two at most, at around 9 seconds.

A few nocturnal clouds expected overnight, some low, may form
in vicinity or behind the frontal boundary, thus partly cloudy
looks buyable as tonights sky descriptor.

As of 615 pm Tuesday... Bowing wind-surge arcing into pender
county soon, marking a leading edge of high pressure, with
enhanced NE gusts, then lowering of dewpoints. Orientation of
said feature nearly perpendicular to a sea breeze front, may
allow isolated pop up convection over the interior corner of se
nc through evening, though probability of measurable rainfall in
any one location 14% or less, as such no pcpn mention in zone
forecasts. Low-level stability is increasing, and CAPE overall
is decreasing.

10-meter winds will peak with anti-cyclone surge, 10-12 mph
sustained average, holding at 6-9 mph for the duration of the
overnight period. This, and 2-meter rh MAX overnight 79-88% will
likely prevent fog mist development. The N to S frontal journey
will bring the coolest min-ts early Wednesday from red springs
to elizabethtown to burgaw, with middle 60s, upper 60s to near
70 most everywhere else.

As of 300 pm Tuesday... A weakening cold front reaching toward
the nc sc border has come up against the sea breeze allowing for
some CU to grow. May see isolated convection before mid to
upper ridge builds aloft suppressing shower activity as we head
into mid week. Drier air behind the front will advect in from
the north as high pressure builds down through tonight allowing
dewpoint temps to drop several degrees, mainly over nc. Expect
temps to range from near 60 in northern counties to around 70
over coastal northeast sc.

Sfc high pressure will continue to build down from the north through
wed before shifting east off the mid atlantic coast through wed
night. Our local area will remain on the southern side of the high
in an easterly on shore breeze on wed. This moderate on shore flow
will keep relatively cooler air mass across the eastern carolinas
through wed. A ridge building aloft should keep it rain free,
although models are hinting at a possible shower developing in
convergence around the base of the high mainly in sc overnight or
wed aftn. Temps on Wed will be near 80 closer to the coast and mid
80s inland. Wed night will be clear and dry with temps in the lower
60s over northern zones and the mid 60s elsewhere.

Short term Thursday through Thursday night
As of 330 pm Tuesday... Surface high pressure centers just off
the nc coast Thursday, as a weak frontal boundary slides towards
the area. Included a slight chance of a shra TSTM over NW areas
where the best moisture lift will reside, however with an
upper-level ridge in place not expecting more than isolated
pcpn. High temps range from the 80s near the coast to the upr
80s lwr 90s inland. Dry for Thursday night under a mostly clear
sky and low temps in the upr 60s.

Long term Friday through Tuesday
As of 330 pm Tuesday... Upper-level ridge remains anchored
across the SE u.S. To start off the long term period. Eventually
the ridge slowly breaks down early next week ushering in nw
flow aloft. Forecast soundings continue to show copious amounts
of mid-level dry air and a strong subsidence inversion aloft.

Precip chances: dry through the whole period.

Temps: about 10 degrees above normal each day. Expect highs in
the mid upr 90s, with overnight lows mainly in the lwr 70s.

Heat advisories seem unlikely given the dry nature of the air
mass.

Aviation 01z Wednesday through Sunday
As of 00z... Cold front visible via satellite as a thin line of
clouds marks the leading edge. Not much weather associated with it,
however an MVFR ceiling is expected, post frontal. Winds will shift
to the east northeast after midnight. Wednesday, MVFR ceilings will
slowly mix out by late morning with continued northeast flow.

Extended outlook... ContinuedVFR through late week as high pressure
dominates. Slight chance of brief MVFR conditions each morning from
low stratus and or fog.

Marine
As of 300 pm Tuesday... A surge of northeasterly winds up around 15
kts or so, will work its way down the coast through tonight,
reaching CAPE fear waters this evening and spreading down into the
grand strand area later this evening. This will push seas up to near
3 to 4 ft building from north to south across the waters tonight
into wed.

Winds will continue to veer around from NE to E as the high
continues to push south, and an on shore flow will continue through
wed. Overall seas will remain in the 2 to 4 ft range most waters.

Winds and seas will diminish heading into early thurs as winds
lighten and shift around to e-se.

Sub-small craft advisory conditions expected to continue for the
remainder of week due to high pressure in place. ~10 kt onshore
flow for Thursday becomes swly Friday at 10-15 kt as a weak
trough drops into the area. Similar wind speeds into Saturday
with an aftn sea breeze developing. Seas only 2-3 ft though the
period.

Sc... None.

Nc... None.

Marine... None.
