Synopsis
A cold front will remain stalled well to our south through the
weekend. High pressure will become centered over new england
Sunday night through Tuesday as low pressure is slow to lift
northeast well off the carolina coast.

Near term until 6 pm this evening
As of 350 am edt Sunday...

as of this morning, surface high pressure at around 1030mb is
located north of the region, centered over new england. Meanwhile, a
cold front is well south of the region, draped across southern sc ga
and extending out along the carolina coast. A shortwave aloft has
allowed for some lower clouds and light showers drizzle to
overspread southern portions of the region (mainly NE nc and far se
va) where low level moisture remains the highest. Fully expect the
precipitation to slowly diminish through the morning hours as drier
air continues to work in from the north. High res model guidance
continues to indicate the possibility for a few widely scattered
showers this afternoon due to strong easterly flow departing
shortwave. Any shower activity should generally be confined to areas
east of interstate 95 and pops are only in the slight chance
category. High temperatures will range from the upper 70s to around
80 under partly to mostly sunny skies to the north with partly to
mostly cloudy skies south and east.

Short term 6 pm this evening through Tuesday
As of 350 am edt Sunday...

the forecast for Sunday night through Tuesday will be largely
dependent on the development evolution of a potential tropical low
pressure system moving slowly NE (but remaining offshore of) the se
us coast. Given that this is likely to be tropical, continued to
generally disregard the NAM as it struggles greatly with anything
tropical. Continued to follow a gfs ECMWF wpc blend (with fairly
decent agreement) centers the sfc low NE off the ga north fl coast
sun night, and lifts it slowly NE well off the carolina coast mon-
tue. High pressure generally remains in place over new england and
atlantic canada through the period. This keep a persistent E to ne
low level onshore flow into the local area.

Deeper moisture looks to stay offshore, but will see a gradual
increase in dew pts and precipitable water values through the
period. Have maintained mostly chance pops for both Mon tue,
primarily due to the moisture overrunning the wedging high rather
than the sfc low itself (as it will be well offshore). Again will
need to monitor the potential tropical development evolution early
next week as a shift closer to the coast would increase impacts
(mainly from higher pops heavier rain potential). Highs will be
mainly in the upper 70s lower 80s mon, and 80-85f tue, with lows in
the 60s Sun night Mon am and mid 60s to lower 70s Mon night Tue am.

Skies will be partly to mostly cloudy.

Long term Tuesday night through Saturday
As of 355 pm edt Saturday...

the early part of the extended forecast will depend much upon any
development and potential track of the tropical disturbance
currently off the fl coast. Latest NHC outlook keeps this system
will stay well off the local coast. Despite that, given the
proximity to the tropical system and the potential for some tropical
type showers to move across the area with a persistent ne-ene flow,
and some reinforcing moisture lift from weak upper disturbances
moving across the mid atlc and NE states in the w-sw flow aloft,
will maintain low chance pops Mon night through thu.

An upper-level trough will move into the great lakes for the end of
next week and the weekend. A cold front will approach the area from
the west. Ahead of the front, conditions should remain mostly dry
with temperature approaching 90 inland and mid 80s along the coast
for the first half of the holiday weekend.

Aviation 12z Sunday through Thursday
As of 700 am edt Sunday...

generallyVFR conditions expected at all TAF sites through
tonight. High pressure to the north will let clouds scatter out
somewhat through this morning and afternoon, especially to the
north and west. Low level moisture lingers closer to the coast
thus skies will remain sct- bkn across the south east. In
addition, a very scattered rain shower cannot be ruled at
eastern TAF sites this afternoon and evening. Gusty northeast
wind of 15 to 20 knots at orf ecg, around 10 knots elsewhere.

Lower clouds may try to develop by early Monday, potentially
creating sub-vfr conditions at all TAF periods for a period of
time.

Outlook: low pressure developing along a stalled front and high
pressure centered to our N NE will keep an easterly flow across
the region mon-tue, allowing for ample moisture, a chance for
showers, and the potential for sub-vfr ceilings from time to time
(especially at eastern TAF locations) mon-tue.

Marine
As of 350 am edt Sunday...

a cold front is pushing swd through nc early this morning
as high pressure builds across the great lakes. The wind has shifted
to nne behind the front 10-15kt, and this has resulted in 3-4ft seas
in the ocean and 2-3ft waves in the bay. The high will build across
upstate ny and into NRN new england today as the front settles off
the carolina coast. Therefore, the wind will shift to NE and remain
10-15kt. The high strengthens and remains nearly stationary tonight.

Meanwhile, an inverted trough begins to develop along the old
frontal boundary and the pressure gradient will tighten along the
mid-atlantic coast. A NE wind should increase to 15-25kt tonight
into Sunday, with seas building to 4-5ft N and 5-6ft S later tonight
into Sunday. SCA flags remain in effect for the bay and lower james,
and have been added for the ocean (primarily for seas) and the
currituck sound. The wind will remain NE Sunday night into Monday as
tropical low pressure organizes off the carolina coast. Sca
conditions for seas (potentially building to 5-8ft) will likely
linger into early next week as the flow remains onshore and with low
pressure over the ocean. By Tuesday night and Wednesday the wind
should become N and then SW as the low pulls well offshore. This
should allow seas to subside.
