Synopsis
A weak disturbance moves across southeastern portions of the region
this morning before lifting off to the northeast by this afternoon.

A cold front approaches Tuesday. Canadian high pressure builds in
from the north Wednesday through Friday. A complex area of low
pressure affects the region next weekend.

Near term until 6 pm this evening
As of 335 am est Monday...

high pressure is located across northeastern portions of the region
early this morning and will continue to push offshore. Patchy fog
has developed once again this morning and is locally dense in spots.

Fog will dissipate across the SE as rain showers approach the region
with any lingering fog fully dissipating after sunrise. Temperatures
range generally the mid 30s to lower 40s. Expect for temperatures to
hold fairly steady for the rest of the night as mid and high level
clouds increase in coverage.

A weak disturbance will impact far southeastern portions of the
region through this morning before lifting offshore to the northeast
by this afternoon. Highest pops are located across NE north
carolina, but there is at least the chance for light rain up into
southeast virginia. Highest precipitation chances shift offshore by
this afternoon. Expecting QPF to remain on the lighter side,
generally under 0.25", across NE north carolina. Outside the area of
precipitation, expect partly sunny skies today with mid and high
level clouds on the increase ahead of a weak cold front. High
temperatures will range from the upper 50s to the lower 60s across
the area.

Short term 6 pm this evening through Wednesday night
As of 335 am est Monday...

a weak cold front approaches the region from the NW Monday night
into Tuesday. However, best forcing remains off to the north of the
region, so still anticipate a mainly dry frontal passage Tuesday
morning into Tuesday afternoon, and have capped pops at slight
chance Monday night and Tuesday. High pressure builds back into the
region by Tuesday night.

Temperature-wise, for Tuesday, highs are expected to make it up into
the mid 50s NW to lower 60s se. Cooler and drier air works into the
region Tuesday night and into Wednesday, which will allow for lows
to drop back into the 30s for much of the area, with highs Wednesday
in the upper 40s into the 50s, under a mainly sunny sky.

Long term Thursday through Sunday
As of 340 pm est Sunday...

dry chilly for thanksgiving Friday as a 1036 mb high moves across
the northern tier states. Lows Wed nite 30-40. Highs thurs lwr 40s-
l50s. Lows thurs nite mid 20s-mid 30s. Highs Fri lwr 40s-mid 50s.

Models show an insitu-wedge scenario developing Friday night as the
sfc high shifts east and off the new england coast with moisture
from a SRN low moving ne. This period will have to be watched as the
moisture from a southern low overspreads the piedmont. As of right
now, the models show the wedge eroding early Sat as winds become se-
s. However, there may be a period of mixed pcpn across the nwrn most
zones as the pcpn come in Fri nite (much like the last system).

Models do differ on speed and moisture fields as a complex area of
low pressure tracks across the mid atlantic region next weekend.

Will bring chc pops in Friday night (liquid for now) with likely
pops sat. Chc to low end likely pops Sat night as the system pulls
to the ne. Lingering pops across the north Sun as upr lvl system
tracks across the region. Lows Fri nite low-mid 30s nw-mid 40s
se. Highs Sat 50 NW to mid 60s se. Lows Sat nite lwr 40s-lwr 50s.

Highs Sun mid 50s-mid 60s.

Aviation 12z Monday through Friday
As of 640 am est Monday...

any patchy fog, particularly across the piedmont, will
dissipate through the morning hours.VFR conditions are likely
for today with mainly mid and higher level clouds. The only
exception will be at ecg and the far SE where light rain has
developed this morning and will last into the early afternoon,
this may lead to sub-vfr conditions in the form of low ceilings
and restricted visibilities at times. A weak, mainly dry cold
front drops across the region later tonight into Tuesday morning
bringing the possibility for short-lived flight restrictions,
particularly across the east, early Tuesday morning.

Outlook:VFR conditions returning late Tuesday afternoon
through at least thanksgiving day, as cool high pressure builds
across the region.

Marine
As of 335 am est Monday...

weak high pressure remains over the area early this
morning, with a trough off the sc coast. The wind is light this
morning and generally W or SW less than 10kt. Seas are mainly 2-3ft.

High pressure will slide offshore today, as the trough lifts NE and
becomes a weak low off the outer banks by this aftn. The wind will
remain light today, generally SW 5-10kt n, and locally easterly ~5kt
s in closer proximity to the low. Another weak area of low pressure
slides across the NRN mid-atlantic, with the wind becoming SW 10-
15kt across the area. A cold front then moves through the area
Tuesday, with the wind becoming NW 10-15kt rivers and 15-20kt
bay ocean sound, then N by Tuesday night and diminishing to 10-15kt.

A 3-6hr period of low-end SCA conditions are possible Tuesday
evening coinciding with 4-6mb 6hr pressure rises. Seas waves build
to 3-4ft 2-3ft. High pressure briefly builds into the region
Wednesday, then another cold front pushes across the coast late
Wednesday night as strong high pressure builds N of the region. Caa
is more robust with this front and will bring the potential for a
period of SCA conditions with a N wind of 15-25kt. Seas potentially
build to 4-6ft N to 5-8ft s, and waves of 2-4ft in the bay. High
pressure lingers over new england later in the week resulting in
persistent onshore flow. A low pressure system potentially impacts
the region Saturday.

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.
