area forecast discussion
national weather service newport morehead city nc
1010 am est Mon nov 19 2018

Synopsis
A weak trof of low pressure along the coast will move east this
afternoon and tonight. A cold front will pass through Tuesday.

High pressure will then build into the region through Friday.

The next storm system will affect the region this weekend.

Near term through today
As of 1010 am mon... Widespread ra continues this morning for
all but southeastern portions of the fa. Will continue seeing
area of decent WAA aloft impinge on upper wave through the
morning, then lift wave moves off to the northeast and offshore
by later this afternoon. Likely cat pops continue for eastern
half through the early afternoon then taper off thereafter.

Previous discussion... As of 7 am mon... Made some adjustment to
pops based on regional radar loop. Back edge of precip presently
in far southeast nc moving northeast. Maintained chance to
likely pops through mid- morning, then quickly taper through the
remainder of the morning into this afternoon, faster than
earlier thought. No change to temps. High temps will range from
the upper 50s lower 60s across the northern tier, to mid 60s
south coast and southern outer banks.

Short term tonight
As of 2 am mon... Skies will clear out this evening as the
coastal trof exits to the east. Boundary layer moisture will
remain high however. Patchy late night early am fog possible.

Lows in the upper 40s inland to lower mid 50s southern outer
banks and south coast.

Long term Tuesday through Sunday
As of 230 am mon... Mostly quiet weather is expected through
Friday as the flow aloft remains quasi-zonal through late week
with prevailing surface high pressure in place though
temperatures will be below normal. The models are starting to
signal more amplification in the upper flow next beginning this
weekend into early next week as the anomalously strong
scandinavian upper ridge retrogrades towards greenland
potentially setting up a blocking -nao -ao pattern d8+ which
could result in a active and stormy pattern next week.

Tuesday... A cold front with limited moisture will move through
the area. Temps are forecast to warm into the 60s ahead of the
front. Will continue slight chance pops though precipitation
amounts will be light.

Wednesday through Friday... High pressure will build over the
area from the north through the period producing cool dry
weather across eastern nc. Highs generally will in the 50s and
lows in the 30s. A reinforcing dry cold front will move through
wed night into early Thursday and 850mb temps drop below zero
across the northern half of the area. Thanksgiving day looks
like the coldest day with highs in the upper 40s to low 50s,
coolest across the northern half of the forecast area, combined
with a brisk nne wind. A hard freeze inland will be possible thu
night- early Fri morning. Could see a few coastal showers fri
as the flow becomes easterly and moisture increases along the se
coast.

Saturday through Sunday... Eastern nc will initially be on the
warm side of the upper air amplification evolving eastern upper
trough. Temps should warm well into the 60s both days but along
with the warmth will come wetter conditions. Surface low
development is being indicated in the gom fri, with the low
moving NE through the carolinas Sat with the potential for
significant rainfall and perhaps a severe weather threat fri
night into sat. Still quite a ways out with significant model
differences between the GFS and ecmwf. Will cap pops for Sat at
high chance for now, though did add sc TSTM mention.

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

as of 7 am mon... A mix ofVFR MVFR at the 4 area terminals.

Upstream obs show generally MVFR conditions which will persist
into this afternoon.VFR conditions will return this evening as
offshore coastal trof moves away. Light and variable winds
through the period.

Long term Tuesday through Friday ...

as of 230 am mon... Lingering sub-vfr ceilings possible Tuesday
morning, then likely lifting toVFR. Isolated showers tue, then
predVFR and dry conditions expected through Friday.

Marine
Short term through Monday night ...

as of 2 am mon... Zones look good. No changes. Weak trof of low
pressure just off the coast will move east later today and
tonight. Very loose pressure gradient across the marine zones
today will result in winds no higher than 5-10 knots, with seas
2-4 feet. Tonight, the pressure gradient begins to tighten up a
bit ahead of the next front. Winds will becoming west increase
to 10-15 knots later tonight, except over the waters north of
oregon inlet where winds take longer to increase, remaining less
than 10 knots. Seas tonight will continue 2-4 feet throughout.

Long term Tuesday through Friday ...

as of 230 am mon... SCA conditions likely Thursday and Thursday
night, with gusty N NE winds and elevated seas. Strong winds
and dangerous seas possible this weekend with the potential for
gale force winds sat. Westerly flow Tue 10-15 kt ahead of a
cold front will become nw-n 15-20 kt behind the front late in
the day into Tue night. 2-4 ft seas will build to 4-5 feet over
the outer waters late Tue and Tue night. Wed, winds will be n-nw
10-15 kt with seas subsiding to 2-3 ft as high pressure builds
over the waters. A cold front will move through the waters wed
night and early Thursday with strong high pressure building in
from the north. Gusty N NE winds 20-25 kt will develop, allowing
seas to build to 4-8 ft Thu and Thu night. E NE flow 10-20 kt
Friday, strongest south of CAPE hatteras. Elevated seas 4-6 ft
could drop below 6 ft Fri afternoon for a brief period before
building back above 6 ft Fri night.

Mhx watches warnings advisories
Nc... None.

Marine... None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
