Area Forecast Discussion
National Weather Service Newport/Morehead City NC
720 AM EDT Fri Jun 7 2024

.SYNOPSIS...
A strong cold front will move through today and this evening,
with weak high pressure building in this weekend. Another front
will move through Sunday night into early Monday.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
As of 715 AM Fri...Radar continues to quickly settle down this
morning as shortwave trough swings offshore. A few isolated
showers will pass along or just south of the Crystal Coast over
the next hour before dissipating.

Focus then turns to this afternoon where the diurnal seabreeze
will provide a focal point for shower and storm development.
Activity is expected to be isolated at best thanks to a much
drier column aloft (PWATs about a half inch lower than this
morning). Westerly surface flow will keep sea breeze and
convective activity pinned along the coast, ensuring the coastal
plain remains dry. Shear will be very weak and no severe threat
is expected. Still very warm today with highs nearing 90
inland, but not as oppressive as Tds fall into the upper 50s
across the coastal plain. Along the coast, humid conditions hold
on with Tds in the upper 60s to around 70.

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM SATURDAY/...
As of 400 AM Fri....Convective activity will quickly collapse
before sunset as cold front eventually pushes offshore tonight
and high pressure builds in its wake. Clear skies and light
winds, coupled with the much drier airmass, will set the stage
for an unusually mild night for early June as temperatures fall
into the low 60s across the coastal plain. More typical
overnight conditions linger along the coast, with overnight lows
in the upper 60s to around 70.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...
As of 310 AM Fri...Mostly dry with a more comfortable airmass
expected this weekend as weak high pressure builds in. Another
front will push through Sunday night and early Monday, bringing
threat for sct showers and storms. Low confidence forecast
Monday night through late week, with still a large spread in the
guidance.

Friday night through Sunday...Upper troughing becomes more
zonal along the east coast through the weekend with weak high
pressure building in, keeping area mostly dry. A more comfortable
airmass expected over the weekend with dewpoints falling into
the 50s and 60s and high temps in the 80s Sat and 80s to low 90s
Sun.

Sunday night through Thursday...A front will move through
Sunday night into early Monday morning, bringing chances for sct
showers and storms. Low confidence forecast Monday night
through late week, with still a large spread in the guidance.
Upper troughing will continue over the eastern US, with
potential for another frontal passage and sfc low development
Monday night through mid week. GFS continues to be the wetter
solution, keeping the front stalled across the area through mid
week. Given lack of run to run consistency and uncertainty,
will continue to trend towards the previous forecast, while
incorporating the newer NBM, increasing pops slightly but
capping at chance.

.AVIATION /11Z FRIDAY THROUGH TUESDAY/...
SHORT TERM /through 06z Sat/...
As of 720 AM Fri...Convective activity is quickly coming to an
end across ENC and VFR conditions continue to prevail. Main
focus for aviation interests is isolated convective potential
this afternoon along the seabreeze. With more westerly to west-
northwesterly flow aloft activity will migrate little from the
coast. OAJ and EWN have the best chance of being impacted, while
coastal plain terminals remain dry. Any activity will quickly
collapse with loss of heating, with skies becoming clear by
tonight.

Breezy westerly winds will gust to 15+ kt at times particularly
across the coastal plain.

LONG TERM /Saturday through Tuesday/...
As of 310 AM Fri...Pred VFR conditions expected through Sunday
with weak high pressure building in. Scattered showers and
storms may impact the sites Sunday night into Monday, which may
bring brief periods of sub- VFR. Brief periods of sub-VFR Mon
night into Tue with sct showers and storms.

&&

.MARINE...
SHORT TERM /through tonight/...
As of 720 AM Fri...Trimmed SCA headlines back to only the outer
central waters where gusty winds around 25 kt are holding strong
particularly near Diamond Shoals.

Prev disc...Convective activity is now pushing offshore,
and marine conditions are improving ahead of an approaching
cold front with southwesterly winds falling to 10-15 kt over
soundside waters, but still 15-20 kt offshore. Seas offshore
range from 2-4 feet north of Cape Hatteras to 4-6 feet south,
although some of this is likely enhanced by convection.

Forecast today calls for gradual improvement through the day as
convective activity pushes offshore and front slowly approaches
from the west. Southwesterly winds will increase this afternoon
to around 15 kt thanks to seabreeze circulations, but will
gradually veer west and the northwesterly overnight into
Saturday as the front crosses the waters. A minority of guidance
suggests a brief surge of northwesterly winds of 15+ kt behind
the front, particularly for the waters north of Cape Hatteras.
If this does occur, it will be brief - no more than a couple
hours.

Only remaining SCA headlines are for the offshore waters south
of Oregon Inlet, and observational trends suggest the advisories
will probably be able to be dropped behind this morning`s
convection.

LONG TERM /Saturday through Tuesday/...
As of 310 AM Fri...Light to moderate N-NW winds Sat 5-15 kt.
Moderate to breezy SW flow returns Sunday ahead of another cold
front. SW winds will increase to 15-20 kt by Sunday evening,
with the front moving through Sunday night into early Monday
morning. A brief period of SCA conditions will be possible with
potential for a few hours of 25 kt gusts. Winds will grad
diminish through the day Mon. Seas 2-3 ft Sat and Sun, building
to 2-4 ft Sunday evening. Another front and low pressure area
may impact the waters Monday night into Tuesday, though given
the spread in the guidance and little run to run consistency,
confidence remains low through mid week. SCA conditions will be
possible.
