Synopsis
High pressure centered over the NE states will ridge down the
east coast and across the carolinas tonight thru Sunday. The
ridging will weaken once the high shifts offshore from the u.S.

A weak disturbance moving across the atlantic waters may clip
coastal areas of nc and sc with isolated showers or intermittent
light rain. Cold high pressure over the plains will push a cold
front across the carolina and off their coasts Tuesday. This
high should maintain dry weather through thanksgiving day. Skies
will slowly cloud up with areas of light rain developing fri
into Sat as a cool wedge sets up.

Near term through Sunday
As of 400 pm Saturday... High pressure, north of local area,
will migrate slowly eastward reaching the nj coast by sun
afternoon. As the high continues to wedge southward into the
carolinas, the winds will veer only slightly, maintaining a
northeast flow. Winds along the coast will become more on shore,
but overall winds will remain very light. As air mass continues
to modify slowly, temps will work their way slowly back to
normal by Sun afternoon. With clear skies and near calm winds
tonight, the atmosphere will decouple and more ideal radiational
cooling will take place. Many traditional cooler places will
reach down into the mid 30s with patchy frost possible. Other
places will see some patchy fog near daybreak with temps in the
upper 30s to around 40. Places along the coast may experience a
slightly more modified flow off the ocean and should see
slightly warmer temps. Most places should reach a few degrees
warmer than today... Into the mid 60s. Moisture return comes
slowly with some dewpoint recovery and in the mid to upper
levels, mainly in the way of increasing cirrus from the deeper
westerly flow aloft, and only few lower clouds on sun. Pcp water
half inch starts creeping up toward an inch on Sunday, mainly
near the coast, where moisture return will be greatest. Overall
should see partly cloudy skies on Sunday with temps reaching
near seasonable, after a cool start.

Short term Sunday night through Monday night
As of 430 pm Saturday... Not much of a longwave pattern change
this period. The longwave upper pattern will continue to
illustrate a low- amplitude trof affecting basically the entire
ilm CWA with ridging along the west coast up to alaska and
somewhat of a flattened ridge extending north in the vicinity of
55w longitude. Overall, this is somewhat of an expansive low
amplitude longwave trof with the mean upper trof line west of
the ilm cwa. There are basically 2 upper jets that will affect
the fa this period and basically meet up across the mid-atlantic
states during this period. This meeting will push a low level
s W trof approaching the fa from the western atlantic back
across the area waters and away from the fa. The subtropical
jet that tracks underneath the west coast ridging and pushes
eastward with not much deviation north or south. The polar jet
is progged to continue to dive southeast out of canada with
successive S W trofs, but does back to an easterly direction and
more or less meets up with the subt jet either across or
offshore from the mid-atlantic states. The 1 mid-level S W trof
does interact with a sfc cold front that will be at the doorstep
of the ilm CWA by Tue morning with the fa seeing a few showers.

Temps this period will likely run 1 to 2 categories above the
norm. Pops for -shra will generally be on the low chance side.

Long term Tuesday through Saturday
As of 500 pm Saturday... The longwave upper pattern to continue
thru this period as identified in the short term. However, mid-
level S W trofs during this period remain active and possibly a
bit more potent. Unfortunately, the best cold air bypasses the
ilm CWA to our north. Which fortunately means no winter wx type
pcpn to deal with, yet. The influence of the subtropical jet
over the polar westerlies continues across the fa, with the sfc
cfp Tuesday followed by CAA that brings temps back down to at or
slightly below normal as a good chunk of canadian high pressure
breaks away and dives to the gulf coast states by Wed and across
the fa thu. A potent S W trof within the polar westerlies pushes
across the NE states early Thu followed by very cold canadian
high pressure that follows a secondary cfp across the fa during
the day on thu. A portion of this cold high is progged to work
it's way across the local CWA due to another wedge setup late
fri into sat. Will see cloud development and light stratiform
liquid pcpn occur by sat. Flow aloft is not conducive to pull
completely onshore the coastal trof that will eventually develop
late Fri into sat.

Aviation 00z Sunday through Thursday
As of 00z... VFR through the overnight hours despite a few ci
passing by this evening. Calm winds and good radiational cooling
will allow for the possibility of some patchy fog inland which may
bring some limited aviation impacts. Do not expect more than light
br and MVFR at flo lbt. With the ci passing to the south, would
expect lbt may have the best chance to reach MVFR. Throughout the
day, should see clear skies with a few mid-level clouds possible in
the northern part of the area as a weak trough moves toward the
coast mid-morning. Toward the end of the forecast period, a small
disturbance moving to the east will bring mid-level clouds.

Extended outlook... Flight restrictions possible overnight Sunday
into Monday due to a weak disturbance off the coast. Otherwise,VFR.

Marine
Near term through Sunday ...

as of 400 pm Saturday... High pressure, north of local area,
will migrate slowly eastward reaching the nj coast by sun
afternoon. As the high continues to wedge southward into the
carolinas, the winds will veer only slightly, maintaining a
northeast flow. Winds right along the coast will become more on
shore, but overall winds will remain very light, 10 kts or less.

Seas will remain 2 to 3 ft most waters.

Short term Sunday night through Monday night ...

as of 430 pm Saturday... No SCA or scec this period. Sfc ridging
will extend across the area waters from high pressure centered
over new england initially that will be exiting off into the
atlantic by daybreak mon. The sfc pg will already be in a
relaxing phase with NE to E directions around 10 kt speeds. A
rather chaotic pressure field encompasses the area waters mon
night ahead of an approaching cold front. An approaching mid-
level S W trof will help sharpen the sfc pg ahead and behind the
cold front that will be on the doorsteps of the fa come sunrise
tue. Sig seas will run 2 to 4 ft thruout this period with a
dominating 9+ second period easterly ground swell.

Long term Tuesday through Thursday ...

as of 500 pm Saturday... Looking at cfp during Tue under gusty nw
to N winds. This will be followed by a secondary cfp during
thu which could see scec or SCA conditions set up especially
from CAPE fear northward. Eventually, the entire CWA waters from
surf city to south santee river will be under a SCA after the
secondary cfp. With N to NE winds at 15 to 25 kt as the sfc pg
tightens in response the wedge setting up. Significant seas will
run 3 to 6 ft by the end of the long term period. This slow
building process is due to a shortened fetch. However, with
winds progged to further veer to the NE or ene by the end of
this fcst, sig. Seas will likely further build.

Ilm watches warnings advisories
Sc... None.

Nc... None.

Marine... None.
