Synopsis
Weak low pressure tracks across eastern north carolina early
this morning and off the outer banks by midday today. A cold
front approaches from the northwest Wednesday and tracks across
the mid atlantic Wednesday night. High pressure returns
Thursday.

Near term until 6 pm this evening
Weak surface low pressure is tracking along a stationary front
across NRN nc early this morning and interacting with shortwave
energy embedded within wsw flow aloft. Areas of showers extend
from s-central va to SE va NE nc, with stronger convection
remaining S of the albemarle sound. Hi-res guidance suggests
some increase in coverage through 12-14z with perhaps some
embedded tstms. The shortwave trough pushes offshore by midday.

There will be some potential re-development of showers tstms by
later this aftn, but will only have a 20-30% pop at this time
given that clouds and onshore flow area likely to persist, which
will hamper any destabilization this aftn. Temperatures early
this morning are generally in the upper 50s to mid 60s N of the
stationary front, with low 70s adjacent to the albemarle sound
in NE nc. Highs today will struggle into the mid 60s along the
immediate atlantic coast of the ERN shore, with upper 60s to low
70s elsewhere on the ERN shore as clouds and onshore flow
persist. Clouds may lift and scatter enough by aftn for highs to
reach the upper 70s to around 80 for central SE va and NE nc,
with low 80s over the piedmont.

Short term 6 pm this evening through Thursday
An upper level trough will sharpen over the great lakes
Wednesday pushing a cold front from the ohio valley into the
appalachians. 30 00z guidance has trended toward more convection
Wednesday aftn due to the combination of increased low-level
moisture an stronger SW flow aloft. Pops have been increased but
capped at 30-40% at this time. Otherwise, dry Tuesday night
into Wednesday morning aside from some stratus and or fog. Lows
Tuesday night range through the 60s, followed by highs Wednesday
in the upper 70s around 80 at the coast to the mid 80s inland.

The mid-level trough axis will shunt surface cold front across
the area Wednesday night. 20-30% pops for showers tstms will
linger into the evening, mainly along and E of i-95. Post-
frontal w-nw flow and surface high pressure building from the
west should combine to yield a dry forecast late Wednesday night
into Thursday. After early morning lows in the upper 50s to mid
60s, highs Thursday should rise in the low 80s inland, with mid
to upper 70s for the lower ERN shore and along area beaches.

Long term Thursday night through Monday
Another unsettled period ahead as the models show a frontal boundary
stalling across the region next weekend with several waves of low
pressure moving along it. This combined with upr level energy and a
good low level moisture feed results in chc pops late Friday through
Sunday night, except likely Sat afternoon and evening as that seems
to be the time frame of the most significant low. Data suggests
locally heavy downpours with another widespread 1-2 inch rainfall
psbl. Highs 80-85. Lows mid-upr 60s.

Latest trends show the system moving offshore Mon with weak high
pressure building into the region. Kept slght chc pops for now until
better confidence of removing pops. Cooler with highs 75-80.

Aviation 08z Tuesday through Saturday
The current surface analysis places high pressure over new
england with a stationary front over NRN nc. Ifr stratus has
spread over most of the area with onshore flow N of the frontal
boundary. As of 06z, only ecg did not have ifr stratus, which
will likely develop there between 10-12z. A trough aloft will
interact with the front this morning, with showers and
potentially a few embedded tstms passing over SE va NE nc mainly
between 08-14z. CIGS are expected to lift in the wake of this
trough, with ifr persisting the longest at sby, potentially
through 16z. A few additional showers tstms may develop later
this aftn into early evening, but the chc is only 20-30% at this
time. The stationary front dissipates tonight as a cold front
pushes into the ohio valley. There is a potential for stratus
and or fog tonight into early Wednesday. The cold front will
push across the region Wednesday night, with a chc of
showers tstms Wednesday aftn evening ahead of the front. High
pressure builds over the area Thursday and slides offshore
Friday. Another cold front approaches from the northwest
Saturday bringing a chc of showers tstms.

Marine
Latest surface analysis centers high pressure over long island,
ridging southward along the northeast and mid-atlantic coasts.

A frontal boundary remains over the southern local area with a
weak area of low pressure over the virginia piedmont. The result
is onshore flow of 10-15 knots early this morning. Few gusts to
around 20 knots observed in the coastal waters and mouth of the
bay. Seas average 3 feet in the southern waters to 4-5 feet in
the northern coastal waters. Buoy 44009 has built as high as 6
feet. Seas in the north are running above guidance due to
persistent onshore flow and swell. High pressure slides offshore
today as the area of low pressure tracks along the front across
north carolina. Onshore flow of 10-15 knots persist. Swell and
winds keep seas in the northern coastal waters around 4-5 feet
today, so SCA headlines have been extended through the
afternoon. Waves 1-2 feet, up to 3 feet in the mouth of the bay.

Low pressure lifts just offshore as another weakening cold
front reaches central virginia tonight. Flow becomes light and
generally offshore. Seas subside to 2-3 feet. A more pronounced
cold front approaches the region Wednesday as southerly winds
increase to 10-15 knots Wednesday. The front pushes across the
waters late Wednesday night. Height rises and modest cold
advection behind the front could result in a period of sca
conditions late Wednesday night into Thursday morning. Northwest
winds diminish Thursday afternoon as high pressure builds in
from the west. High pressure slides offshore Thursday
night Friday with flow returning to the south. The next front
crosses the waters Saturday night.

Tides coastal flooding
Onshore flow swell and high astronomical tides have resulted in
elevated water levels along the atlantic coast and in the bay
and tidal rivers. Tidal departures are around 1 foot. A coastal
flood advisory remains in effect for the tidal areas surrounding
bishops head early this morning. While tidal departures are
expected to remain around 1 foot through Wednesday night (ahead
of an approaching cold front) lower astronomical tides are
expected to keep levels below minor flooding thresholds.

Akq watches warnings advisories

mdz021>023.

Nc... None.

Va... 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.
