Synopsis
High pressure will build into the area today. Low pressure will
pass north of the region tonight. A cold front will cross the
region late Thursday. Low pressure will pass near the coast
Friday. High pressure will build over the area this weekend.

Near term until 6 pm this evening
As of 330 am Wednesday... The cold front has moved through the
area followed by a quick shot of modified arctic air today.

Skies have cleared with breezy inland windy conditions coast
this morning. Winds will briefly diminish this afternoon but
increase again late tonight. Will end the outer banks wind
advisory at 11z based on the latest model wind forecasts which
indicate a quicker diminishing trend. Strong cold advection will
be tempered by full insolation and downslope flow, thus went
closer to the mav met MOS vs the colder ecmwf. Expect highs
north in the upper 30s to the lower 40s south.

Short term 6 pm this evening through 6 am Thursday
As 330 am Wednesday... A clipper low pressure system will pass
to the north of the region tonight producing increasing winds
and a period of mostly cloudy skies this evening. Precipitation
chances with this system will occur north of the state as the
sub cloud layer over eastern nc is forecast to be very dry.

Think low temps will occur before midnight when winds will be
lightest, then increasing SW flow will lead to warming temps
late. Expect min temps inland in the upper 20s and low to mid
30s closer to the coast. The immediate coast should remain above
freezing.

Long term Thursday through Tuesday
As of 330 am Wednesday... An upper trough will persist across
the eastern CONUS through the rest of the week with a series of
shortwaves moving through the flow aloft, although expect dry
conditions as moisture will be limited. Weak ridging builds into
the area this weekend with a system moving into the region
early next week bringing a better chance of rain.

Thursday and Thursday night... The shortwave trough pushes
offshore Thu morning and will see clearing skies early with wsw
flow continuing much of the day with the front progged to push
through late in the day. Low level thicknesses suggest highs
generally around 50-55. High pressure briefly builds into the
region Thu night with lows expected in the low to mid 30s inland
around 40 along the coast.

Friday and Friday night... Another mid level trough approaches
the region Fri and pushes across the region Fri night. Weak low
pressure develops across the southeast in response and lifts
across or just off the nc coast fri. Will likely see more clouds
than the previous system but the sub-cloud layer remain fairly
dry and not anticipating any precip. The low lifts NE of the
area Fri night and deepens with CAA ramping up. Highs fri
generally in the mid to upper 50s with lows in the low 30s
inland to around 40 coast Fri night.

Saturday through Sunday... Weak ridging and sfc high pressure
build into the region this weekend keeping conditions dry. Cool
temps expected Sat with highs in the upper 40s to around 50 and
lows in the lower 30s inland to around 40 along the coast sat
night. High pressure moves offshore Sun with increasing clouds
ahead of the next approaching shortwave. Return flow will bring
a warming trend Sun with highs expected in the mid 50s to
around 60.

Sunday night through Tuesday... A better chance of rain expected
early next week as a series of shortwave troughs lift out of
the southern plains and lift across the area tapping into gulf
moisture. There remains some spread among guidance, especially
with the timing of the systems, so confidence is rather low in
this regard but it appears the best chance for widespread precip
comes Sunday night and Monday. Slower guidance suggests precip
may linger through Tuesday. Temps expected to be above normal
this period with predominant SW to W flow across the region.

Aviation 08z Wednesday through Sunday
Short term through tonight ...

as of 330 am Wednesday... High confidence inVFR conditions
through the TAF period. Expecting clear skies with gusty nw
winds to 20 kt this morning diminishing this afternoon and
evening, then increasing out of the SW with gusts to 20 kt
possible late tonight. A mid cloud deck associated with low
pressure passing by to the north will move across the area this
evening, then skies should clear late. There will be a llws
threat tonight as wind fields increase aloft.

Long term Thursday through Sunday ...

as of 4 am Wednesday... PredVFR conditions expected through the
long term. A shortwave trough and weak surface low pressure
push across the region Fri bringing increasing clouds but cigs
expected to remainVFR. High pressure builds back into the
region over the weekend but will see increasing clouds Sun in
advance of the next system approaching the region.

Marine
Short term through tonight ...

as of 330 am Tuesday... Ongoing gale force NW winds will
diminish to 10 to 20 kt this afternoon as high pressure briefly
builds over the waters through this evening. Winds are then
forecast to back to the SW and increase again to minimal gale
force late this evening as low pressure moves north of the
waters overnight and tightens the pressure gradient. Thus will
extend the gale warnings through tonight south of oregon inlet
and for the pamlico sound. 7-10 ft seas early this morning will
subside to 3 to 5 ft late today then build rapidly to 7 to 10 ft
late this evening.

Water levels across the western portions of the neuse and pamlico
rivers of to 1 to 2 feet below normal early this morning will
increase to normal levels this afternoon.

Long term Thursday through Sunday ...

as of 415 am Wednesday... Several shortwave troughs and
attendant cold fronts push across the waters through the long
term bringing poor boating conditions much of the period.

Wnw winds around 20-25 kt with gusts around 30 kt with seas
around 6-10 ft southern central waters and 4-7 ft north to start
thu gradually diminishes through the day as low pressure moves
off the mid-atlantic coast. The attendant cold front pushes
through late Thu with winds becoming wnw around 10-20 kt, then
becomes NE around 5-10 kt with seas subsiding to 2-4 ft thu
night with weak high pressure building in from the north. A weak
area of low pressure is progged to move across the waters fri
with winds becoming SW around 10-20 kt by late Fri afternoon,
then NW around 15-25 kt Fri night as the low rapidly deepens off
the mid-atlantic and new england coast. Seas build back to 4-7
ft late Fri and Fri night. Winds gradually diminish to W to nw
around 10-15 kt Sat afternoon with seas subsiding to 2-4 ft late
as high pressure builds into the region. Winds veer and weaken
sat night becoming E around 10 kt Sun morning, then becomes s
around 10-20 kt Sun afternoon as the high moves offshore the the
next system approaches from the west. Seas around 1-3 ft sun
morning build to around 3-5 ft late in the day.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
