.SYNOPSIS...
High pressure slides offshore tonight. A weak warm front will move
north through ENC Sunday morning before a cold front crosses in the
evening. Behind this system high pressure will briefly build in from
the north Monday, with a stronger low pressure system expected to
move across the Carolinas Tuesday. High pressure then rebuilds into
the area from the north through midweek before another low pressure
system impacts the region late next week.

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
As of 1830 Saturday...Typical cold spots decoupled with sunset,
have brought down hourly Ts to better capture this early evening
T crash, which nudged the MinTs slightly lower. Still expecting
Ts to stagnate, maybe rise latter half of the overnight.

Previous Disco...as of 2:30 PM Sat...

Key Messages...

- Cold conditions expected again tonight with lows below freezing
inland

High pressure will gradually push offshore while a weak warm
front/coastal trough begins to track north near the coast
towards daybreak Sunday. As a result, some increasing cloud
cover may approach the area near daybreak Sun with isolated to
widely scattered showers also possible along the OBX. But, any
inland areas will remain dry regardless of shower coverage. In
addition to this, as the high pushes offshore, winds are
forecast to shift to an E-SE direction overnight. This will
allow for some moisture recovery overnight and some WAA. So what
does this mean for the ambient weather for ENC tonight? The
first is that we will likely have a pre-midnight low as temps
drop rapidly into the upper 20s to low 30s inland and into the
low 40s along the OBX just after sunset with temps then
remaining steady and maybe even rising a few degrees after
midnight and into daybreak Sunday as cloud cover and WAA
increases. The second is the potential for some fog tonight.
Right now guidance isn`t too keen on any fog development tonight
outside of a few more pessimistic models like the RRFS which
shows a bit more low level moisture recovery overnight.
Currently discounting this however given how dry it has been and
the amount of low level moisture needed to even get fog is on
the higher end. With crossover temps too cold as well, leaning
on a fog less night tonight. With all this in mind, while the
threat is likely 10% or less can`t rule out some patchy fog
completely yet, especially east of Hwy 17.

.SHORT TERM /6 AM SUNDAY MORNING THROUGH 6 PM SUNDAY/...
As of 230 PM Sat...

Key Messages...

- Rapidly moderating conditions Sunday as a warm front lifts through
the area with highs in the mid to upper 60s possible

- Isolated to scattered showers possible Sunday ahead of and along a
cold front which will move through the area Sunday evening

As the warm front lifts north through ENC Sunday morning, southerly
flow begins in earnest behind the front. This is forecast to bring
much warmer temps to the area with highs getting into the 60s on
Sunday. A fair amount of clouds are likely with moisture increasing
as well, but this should only act to limit temps from getting into
the 70s on Sun. Continue to also see the signal for isolated to
widely scattered showers ahead and along an incoming cold front.
Cold front is forecast to sweep E`wards across ENC Sun
evening/night. Have kept SChc to Chc PoP`s in the forecast given
this, though rainfall amounts will likely be very light generally
0.15 inches or less.

.LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/...
As of 245 PM Sat...

Key Messages

- A strong low pressure system will impact ENC Tuesday into
  Wednesday with the potential for heavy rain, gusty winds, and
  minor coastal flooding

- Below normal conditions continue the rest of next week, with
  the potential for another low pressure system to move through
  the Carolinas late week

An active weather pattern is shaping up early to mid next week.
During this time, upper level troughing is forecast to develop
across the central U.S., with southwesterly flow developing
aloft across the southern U.S. At the SFC, a notably strong area
of low pressure is forecast to develop along the Gulf Coast
Monday, then lift NE through the Southeastern U.S. early next
week.

The majority of guidance continues to depict low pressure
taking a "just" inland track as it moves through the Carolinas
and up into the Mid-Atlantic. Though there remains some
uncertainty with the track and intensity still, most model
solutions show the potential for Gale Force winds and heavy rain.

With this track we will be on the "warm" side of the low, but
just barely. There remains potential for some convective
elements and thunder, but this should be mostly confined to the
immediate coast and over the nearshore marine waters. A plume
of anomalous moisture and strong forcing, appears supportive of
a period of moderate to heavy rain along the track of the low.
Ensemble guidance and other forecast aids continue to show a
notable signal for heavy rain (1-2"+). The rain is much needed
as a large portion of ENC remains in a moderate drought. That
said, some minor nuisance flooding cannot be ruled out for
areas that see higher rainfall totals and/or higher rain rates.

For coastal areas, especially the Outer Banks, we`ll have to
closely monitor the potential for oceanside and soundside
flooding impacts due to the potential for strong winds, large
waves, and a higher tide cycle.

High pressure briefly builds in towards the middle of the week,
but this may be short-lived as yet another coastal low may
impact the area towards the end of next week.

Temperatures fall back down below normal Monday, but bounce
back up on Tuesday. Below normal conditions then likely return
for the rest of the week.

.AVIATION /00Z SUNDAY THROUGH THURSDAY/...
As of 1830 Saturday...VFR flight cats prevailing through much
of tonight, then a low chance for sub-VFR conditions late
tonight into Sunday morning.

Arctic airmass across the region this evening. The SFC high
continues to slide off the DelMarVA coast tonight, with low
level flow slowly veering to SE Sunday morning, and eventually
Sly Sunday afternoon ahead of an approaching cold front. Fog
potential remains very low tonight despite gradual dewpoint
recovery overnight as temps will remain well above cross-over
temps. However, cannot completely rule out shallow ground fog,
mainly across eastern rtes closer to the coast given near
saturated conditions. Could also see stratus moving onshore late
tonight into Sunday morning as low-level flow veers to SE
nudging remnant boundary offshore toward the coast, bringing
the potential for a period of MVFR CIGs. Probs remain quite
low, generally less than 30% and will keep mentions to few-sct
at coastal TAF sites. Could see a period of sub- VFR conditions
with widely scattered showers ahead of a cold front Sunday
evening. 18Z guidance has leaned more toward the lower cloud
bases associated with the prefrontal trough and the showers
accompanying it tomorrow. Have introduced a sub FL050 cloud
group for the afternoon timeframe, but still keep CIGs VFR for
the time being. PoPs currently forecast less than 20% so no
mention of SHRA in TAFs this cycle. Slightly better chances of
MVFR flight cats when cold front works through the FA from NW to
SE after the end of this TAF cycle.


Outlook: High pressure builds back into the area Monday with
pred VFR conditions expected. Widespread sub- VFR likely Tuesday
as a low pressure system is forecast to lift along the coast.
High pressure builds back into the area Wednesday and Thursday
with pred VFR conditions expected.

.MARINE...
As of 245 PM Sat...

Key Messages...

- Small Craft conditions likely develop late Sunday night behind a
cold front through most of Monday

- Increasing potential for Gale Force winds Tuesday as a strong low
pressure system moves over the Carolinas

- Hazardous boating conditions will likely continue into Wednesday

No big changes today in the forecast as relatively benign
boating conditions are noted across our waters this afternoon
with widespread 10-15 kt N`rly winds with 20 kt gusts and 2-4 ft
seas noted across our waters today. Winds veer tonight to an
east and then southeasterly direction as a weak warm
front/coastal trough lift north across our waters Southerly
winds increase to 10-20 kts Sunday afternoon, and then switch to
the NW late Sunday night behind a cold front. Winds strengthen
to NNW 15-25 kts with gusts to 30 kts overnight into Monday
morning. Isolated to widely scattered showers will be possible
as well along the warm front Sun morning and then again out
ahead and along a cold front approaching from the west Sun
evening/night.

Seas will be mostly 2-3 ft through Sunday evening with seas then
quickly building after midnight Mon from north to south to 4-6 ft.

Outlook: Improving conditions expected after sunrise Monday, but
this will be short lived as a strong low pressure system is expected
to move through the coastal waters Tuesday. There is potential for
Gale Force winds across much of the coastal waters, with the exact
strength of the winds (and wind direction) still to be worked out.
Hazardous marine conditions will continue for some time behind this
system through Wednesday.

.TIDES/COASTAL FLOODING...
As of 245 PM Sat...A strong low pressure system moving through
North Carolina Tuesday will bring elevated winds and seas. This
comes as we enter a king tide cycle Tuesday (12/2) through
Monday (12/9) of next week. Areas with vulnerable dune
structures along the Outer Banks have the potential to see minor
coastal flooding, heightened during Tuesday evening`s and early
Wednesday morning`s high tides. The forecast magnitude and
direction of winds and waves with this system depends on the
eventual track and strength of the low pressure system. And as a
result, specific coastal flooding impacts and their severity
are still unclear at this time.
