area forecast discussion
national weather service newport morehead city nc
1049 am edt Fri oct 20 2017

Synopsis
High pressure will build over the region through Saturday and
then slide offshore Sunday into Monday. A strong cold front will
approach from the west Tuesday and move across the area Tuesday
night into early Wednesday. High pressure will build over the
area mid to late week.

Near term until 6 pm this evening
As of 1045 am Friday... Minor adjustments to hourly temp and dew
point trends, otherwise high and dry forecast on track.

Previous discussion
as of 615 am Friday... High pressure surface and aloft will
continue over the area through tonight producing mostly clear
skies and light winds. A thin veil of high cirrus clouds will
stream south across the area today around the upper ridge. Areas
of locally dense radiational fog early this morning should
dissipate around 13z (9 am) this morning. Highs today should be
similar to Thursday, around 80 degrees inland and the mid to
perhaps upper 70s beaches.

Short term 6 pm this evening through 6 am Saturday
As of 300 am Friday... Clear skies light winds continue with
patchy fog expected to develop again inland after midnight.

Lows will range from the upper 40s inland to around 60 beaches.

Long term Saturday through Thursday
As of 330 am fri...

Saturday through Sunday... High pressure centered over the area
will move off the coast this weekend with warming temps and
slight rises in humidity values. It will continue mainly sunny
through the weekend. High temps will be in the upper 70s to low
80s both Sat and sun. Morning lows will be in the 50-55 degree
range interior to low 60s beaches.

Monday through Tuesday... Next significant shortwave cold front
moves into the eastern CONUS by early next week. 20 00z global
model suite has converged on timing strength of deep upper
trough and strong cold front progged to move through the region.

Thus have enough confidence now to advertise likely pops on
Tuesday, with chc pops Monday Monday night. Upr ridging still
overhead on Monday, though low level flow veers southeast and
strengthens, so some sct showers may advect onshore across the
fa as boundary layer moisture increases through the day.

On Monday night and especially Tuesday, vorticity advection
increases as models depict dampening shortwave trough pivoting
through the tn ohio valleys. This feature will spur cyclogenesis
west and north of the carolinas acting to increase dynamics and
strengthening southerly flow on 50+ kt llj. Dewpoints will rise
steadily through the 60s by Tuesday, and the combination of
significant wind shear and marginal instability could spell a
high shear low CAPE scenario for strong or severe storms. Too
early to depict storm mode, but will have to monitor as the
potential will be there for severe if enough instability
present.

Wednesday into Thursday... Rapid drying and cooling expected by
Wednesday as the front should move off the coast Tue night or
early wed. Have retained the small pops for Wednesday as the
deep upper low moves through E nc and could produce a few
showers. Dry NW flow on thur as upper low finally exits off the
mid atlantic coast. Temps will be much cooler for the mid week
period with Wed and Thu both in the 60s for highs. Temps fall
back into the 50s for Wed morning, then into the 40s inland and
low 50s beaches for thur morning.

Aviation 15z Friday through Tuesday
Short term through tonight ...

as of 615 am Friday... Areas of locally dense fog at near the
taf sites will dissipate around 13z this morning withVFR
conditions and light winds expected through this evening. Could
see another round of fog and subVFR conditions develop after 6z
tonight under similar conditions as last tonight.

Long term Sat through Tue ...

as of 330 am fri... PredVFR conditions expected through the
weekend. However, there may be overnight early morning fog all
taf sites this weekend as low level moisture increases and skies
remain clear with calm winds each night. Sub-vfr possible in
scattered showers spreading in from the southwest Monday into
Monday night, with better chance of widespread MVFR ifr by
Tuesday as a strong cold front approaches the region. Winds
light through Monday, then gusty south winds expected on Tuesday
ahead of the front.

Marine
Short term through tonight ...

as of 1045 am Friday... No changes with update.

Previous discussion
as of 615 am Friday... High pressure will continue over the
waters through tonight producing excellent marine conditions for
most mariners. Wind speeds will be mainly 10 kt or less through
the period with the flow W NW today becoming N NE tonight. Seas
are forecast to be 2 to 4 ft today and 2 to 3 ft tonight.

Long term Sat through Tue ...

as of 330 am fri... Northeast to east winds remain light in the
5-10 kt through the weekend. Seas will be 2-4 ft. Winds will
turn southeast on Monday as high pressure moves further
offshore. Winds will slowly increase from 5-10 kt in the morning
to 10-15 kt by late in the afternoon. Seas will be 2-4 ft north
of CAPE hatteras and 3-5 ft south. Winds increase drastically
Monday night and peak on Tuesday ahead of a strong cold front
approaching from the west. Speeds will be 20-30 kt with some
gale force gusts possible on Tuesday. Seas increase to 7-11
feet on Tuesday.

Mhx watches warnings advisories
Nc... None.

Marine... None.
