Synopsis
A trough of low pressure will stall and dissipate near the
southern sections today. High pressure will extend into the
area from the northwest Friday through the weekend. Hurricane
maria is expected to track between the bahamas and bermuda early
next week.

Near term through today
As of 3 am Thursday... Patchy fog possible early today otherwise
another day filled with plenty of sunshine, especially through
late morning. Toward 18z hi resolution guidance matches up well
with our previous forecast of scattered thunderstorms
developing. This will be most likely along the sea breeze and
especially near or on a line from morehead city to new bern to
greenville, south and west. SPC keeps our area in general
thunder and see no reason to expect more than garden variety
thunderstorms through late today. Highs will once again be above
average with upper 80s inland, about 6 degrees warmer than
typical late september highs. It will be cooler near the
beaches. This will be most pronounced over the outer banks with
a cooler northeast wind holding temps in the lower 80s.

Short term tonight
As of 3 am Thursday... Any thunderstorms early this evening
should die down rather quickly. I did leave a slight chance
mention in through midnight over the far southwest based on what
happened last night, and continued good model agreement that an
isolated storm may persist in the areas just mentioned. With
lows dropping back into the 60s again, patchy fog will be
possible especially in areas that see rain later today.

Long term Friday through Wednesday
As of 3 am thu... High pressure centered over the great lakes
will extend down across the region through the period, while we
continue to monitor hurricane maria. Some uncertainty continues
regarding the track of maria. Eastern nc residents and
interested parties should continue to monitor the latest
official forecasts from nhc.

Friday through Saturday night... Surface high pressure and upper
ridge will continue to build in from the north through the
weekend, as jose gradually weakens and meanders off the NE and
mid-atlantic coast. Pred dry weather expected. Low level
thickness values support temps near to slightly above normal
through the period with highs in the upper 70s to mid 80s and
overnight lows in the mid 60s to low 70s.

Sunday through Wednesday... Hurricane maria is currently
forecast to slowly lift north off the SE coast through mid week.

Eventual track will be determined by several factors including
the strength of the upper ridge and circulation of jose. It is
still too soon to determine specific impacts for eastern nc,
which will be very dependent on the track how close to the coast
it gets. Regardless of the exact track, rough surf and
dangerous rip currents are likely this weekend into next week,
as large long period southeast swells build. Gusty N NW winds,
minor coastal flooding, and ocean overwash erosion will be also
possible.

Have introduced rain chances into the forecast beginning along
the outer banks and adjacent coastal waters Sunday. Then, slight
chance to chance pops gradually spread into the forecast area
from the east Sunday night through early next week as maria
passes by off the coast. Rain chances then decrease Tuesday
night into Wednesday as the system moves away.

Eastern nc residents and interested parties should continue to
monitor the latest official forecasts from NHC on hurricane
maria.

Aviation 06z Thursday through Monday
Short term through 00z Friday ...

as of 150 am Thursday... Already some light fog at kewn and kpgv
the past few hours. With temps already near afternoon crossover
temps and or near the dewpoint temperature, at least MVFR vsbys
possible all terminals through 12z. Where confidence is highest
in slightly longer coverage, included some brief ifr vsbys for
kewn and kpgv. A return toVFR expect by 13z.

Later today a few thunderstorms will be near the terminals.

Not enough coverage to warrant inclusion in tafs yet.

Long term Thursday night through Monday ...

as of 3 am thu...VFR conditions will dominate most of the
period, though some early morning fg br and low stratus may
develop each night as a ridge of high pressure will be across
the region.

Marine
Short term through Thu ...

as of 3 am Thursday... Small craft advisories continue as is.

Seas subside a bit today and this should be enough to drop the
northern waters north of oregon inlet to below 6 feet, and will
let the advisory here expire at 6 am unless obs show otherwise.

It should be noted that we may need to reissue an advisory here
for later tonight into Friday as seas build once again.

Across the central waters from oregon inlet south to ocracoke
inlet, marginal seas will remain (4 to 6 feet) to keep the small
craft advisory going through tonight. Could see a few hours of
below small craft conditions later today but not a long enough
period to change any headlines, before seas builds again toward
6-7 feet after midnight tonight. Winds north to northeast 5 to
10 knots through the period.

Long term Fri through Mon ...

as of 3 am thu... High pressure centered over the great lakes
will build down into the region through the period, while we
continue to monitor hurricane maria. Some uncertainty continues
regarding the track of hurricane maria late this weekend and
next week. Mariners and interested parties should continue to
monitor the latest official forecasts from nhc.

N NE winds 5-10 kt Fri increasing to 5-15 kt Sat and 10-20 kt
sun and mon. Nwps and wavewatch in good agreement with elevated
seas lingering across the central waters through the entire
period. Will likely start seeing long period southeast swell
build from distant hurricane maria Fri into early next week
across all the waters. Small craft seas likely to redevelop by
fri evening in the waters south of ocracoke and continue into
next week, with double digit seas by Sunday and Monday. Too soon
to determine specific impacts from maria, but dangerous seas
expected and strong N NW winds will be possible. Large SE swells
expected to build, wavewatch currently showing swells 15-20
ft 15 seconds. Rough surf and dangerous rip currents are likely.

Mhx watches warnings advisories
Nc... Beach hazards statement through this evening for ncz095-103-
104.

Marine... Small craft advisory until 8 pm edt Monday for amz152-154.

Small craft advisory until 6 am edt early this morning for
amz150.

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.
