area forecast discussion
national weather service newport morehead city nc
120 pm edt Mon aug 21 2017

Synopsis
High pressure will extend over the area from offshore today
through Wednesday, then a cold front will move through
Wednesday night and Thursday. Strong high pressure will build in
from the north Friday through Sunday, while areas of low
pressure move along the stalled frontal boundary off the
southeast coast.

Near term until 6 pm this evening
As of 120 pm Monday... Made some additional tweaks to fine tune
cloud cover. Majority of the area should have decent eclipse
viewing conditions, with the unfortunate exception of the
southern coastal area. There are some clouds skirting the coast
and some isolated showers in this area that will not make for
optimum sky conditions for viewing the sun. If attempting to
view the eclipse be sure to use verified approved eye
protection. It will not be safe to view the eclipse directly at
any time this afternoon with the naked eye.

Previous discussion
as of 315 am Monday... Weak high pressure extending over area
from NE will gradually move E today as heights build slightly
aloft and sheared vort axis extending sw-ne across area weakens.

Scattered showers isolated TSTM over water from near CAPE fear
to 40 nm east of CAPE lookout will gradually approach southern
coastal sections early this morning, then expected to diminish
by mid-morning. Isolated convective activity possible over
southern sections late morning through afternoon with weak
convergence along sea breeze pushing in from s-se.

Patchy dense fog and low stratus currently developing and will
affect mainly inland areas through around 8 am.

Current band of ci assctd with sheared vort axis expected to
thin and diminish from w-sw this morning with just fair weather
cu scu for this afternoon, with cloud cover a bit thicker
southern sections with convergence along sea breeze.

Max temps from mid 80s outer banks to around 90 inland.

Short term 6 pm this evening through 6 am Tuesday
As of 315 am Monday... Models are indicating no precip threat
over area this evening, then possible offshore activity
spreading near coast overnight with surface flow becoming light
s-sw as high pressure continues to drift offshore. Adjusted pops
accordingly with just a slight chance along coast after 2 am.

Some patchy fog possible for inland sections again late tonight.

Min temps from lower 70s inland to mid-upper 70s coast.

Long term Tuesday through Sunday
As of 255 am mon... Forecast remains on track with a quiet start
to the week followed by increasing rain chances Wednesday into
Thursday. Much cooler weather expected late week and this
weekend.

Tuesday through Thursday... Hot and humid weather will continue
through Wednesday ahead of the approaching cold front, with high
pressure extending over the area from offshore. Highs Tue and
wed in the upper 80s to low 90s, dewpoints in the 70s, and heat
indices near 100 deg each afternoon. Isolated to widely
scattered showers and pulse type tstorms possible Tue across
the southern half of the forecast area. The slow moving front
will push into the area Wednesday night and Thursday. This front
will be an anafront with the best chance for precipitation
along and behind it. Will continue high chance to likely pops
developing ahead of the front Wed afternoon, with the most
likely period for precip coming Wednesday night into Thursday.

By Thursday however cooler air aloft, clouds, and rain chances
will keep high temps in the lower 80s.

Friday into Sunday... .Strong high pressure will build in from
the north, with broad upper troughing across the area, while
areas of low pressure are forecast to move along the stalled
front off the SE coast. Scattered showers and isolated storms
fri, with best chances along the coast. Much drier air filters
into the area this weekend, with forecast soundings showing pwat
values dropping below 1" Sat and sun. Low level thickness
values and NE E flow support temps several degrees below normal,
with highs in the upper 70s to low 80s and overnight lows 60-70
degrees. Some guidance even has some inland spots dropping into
the upper 50s this weekend. Depending on the track and strength
of low pressure areas off the coast, could see some showers
skirt the coastal areas but at this time expect bulk of precip
to remain offshore.

Aviation 17z Monday through Friday
Short term through 12z tue
as of 120 pm Monday...VFR conditions currently prevail across
the area and this will continue into early tonight. Patchy
fog stratus will again be likely inland late tonight and ifr
conditions will be possible at all TAF locations.

Long term Tuesday through Friday ...

as of 255 am mon...VFR through Tuesday. Sub-vfr conditions
possible Wednesday into Friday in scattered showers and storms.

Ne flow developing behind the cold front Wed night and thu,
could keep low stratus locked in across the area into Thursday
night before we see a return predVFR conditions fri.

Marine
Short term through tonight ...

as of 120 pm Monday... Updated winds based on latest guidance,
but did not change the forecast in any appreciable way.

Previous discussion
as of 315 am Monday... Good boating conditions through tonight
with weak high pressure extending over the area. Scattered
showers isolated TSTM will affect southern waters early this
morning, then just a slight chance rest of day and again late
tonight. Winds will gradually veer from E to SE today, and then
to s-sw tonight as high pressure gradually moves offshore.

Speeds remaining 10 kt or less. Seas mainly 2 feet today,
building to 3 feet outer portions tonight.

Long term Tuesday through Friday ...

as of 255 am mon... A prolonged period of moderate to strong ne
winds expected behind the front Thursday night through the
weekend. SCA conditions likely to develop this coming weekend,
as early as Friday.

High pressure will continue to extend over the waters from
offshore Tue and wed, with light SW winds less than 10 kt and
seas 2-3 ft early Tue increasing to 10-15 kt and 2-4 ft in the
afternoon. The gradient will tighten Tue night and Wed ahead of
the front, with SW winds increasing to 10-20 kt and seas
building to 3-5 ft. The slow moving front will push through the
waters Wed night and Thursday, with winds gradually becoming ne
10-15 kt behind the front. Strong high pressure will build in
from the north Thu night and fri, while areas of low pressure
are forecast to move along the stalled front off the SE coast.

Ne winds will increase to 15-25kt Thu night and Friday with seas
building to 4-6 ft. Gusty NE winds and rough seas are expected
to continue into the weekend and early next week.

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.
