Synopsis for coastal waters from surf city north carolina to south santee river south carolina out to 20 nautical miles.. A cold front will stall near the coast today and then move just offshore Sunday and Monday. Meanwhile, some gradual development is possible with an area of low pressure to move ne from the bahamas and florida Sunday and Monday.

Synopsis
Unsettled weather is expected today as a front stalls over the
area. The front will move just off the coast through Sunday and
Monday. Meanwhile, a tropical low will track north up through
the offshore waters of the southeast coast late Sunday and
Monday, lifting off to the northeast through midweek.

Near term through Sunday
Much advertised cold front has begun to move into the ilm cwa. N
winds have spread through entire area (where it hasn't decoupled)
but main temp dewpoint boundary is lagging. Overall ill-defined
boundary will get hung up near the coast today, and as synoptic nly
flow collides with the sea breeze in a still moisture rich
environment (esp closer to coast), expect numerous showers and tstms
to develop. Main threat with the stalling front appears to be
pockets of heavy rainfall that may lead to some nuisance flooding in
prone areas, though widespread issues not anticipated. Various
precip ensemble products showing roughly 20-40% chance of greater
than 1" for much of our coastal area, with some lower end
probabilities for >2" esp. Near the CAPE fear region. Otherwise
expect considerably cooler temps today ranging from upper 70s far
northern areas to mid 80s over southern tier.

Convection should gradually wane and shift offshore through early
Sunday morning as high pressure begins to wedge in from the north.

Rain chances will increase again into the afternoon, but
coverage QPF not as high compared to today, with better established
ne flow between high pres and tropical low pressure beginning to
lift NE from florida. Best chances near the coast in the afternoon.

Will need to monitor placement of tropical system closely on Sun as
inverted troughing north of the feature could enhance rainfall, but
bulk of that is presently expected to be offshore. Temps continue
below normal on Sunday with N NE flow and abundant cloudiness.

Short term Sunday night through Monday night
High pressure will run down through the carolinas from the
north as tropical low tracks up through the offshore waters off
of the southeast coast Sun night through Mon night. A lingering
frontal boundary may also aid in convergence along or just off
the coast. Gradient will tighten with stiff northeast winds
developing along the coast and off shore. This will continue to
feed moisture on shore and expect to see some gusty showers
passing across the area, especially along the coast. Looks like
best chance of heavier showers or convection will run up through
the nc coast. The ECMWF continues to be the farthest off shore
and strengthens the system as it reaches just over 300 miles
east of the CAPE fear on Monday. GFS runs up closer to the
coast, about 150 miles off the coast on Monday, but remains
weaker. NHC continues to support gradual development of this low
with a tropical or subtropical depression likely to form as it
tracks up through the offshore waters off of the southeast
coast. The chance of development is up to 90 percent. Overall,
expect plenty of clouds around with best chc of pcp along the
coast, but if storm is farther east and stronger, it could draw
drier air in from the north.

Main effects of this system should be felt across the coast and
over the waters with increasing winds and rough seas and
enhanced rip current activity along area beaches. Depending on
how far off the coast the system moves, will determine how much
rainfall it brings, but can not rule out some areas experiencing
gusty shower with heavier rain. Also will see relatively cooler
northerly flow keeping temps several degrees below normal during
the day.

Long term Tuesday through Friday
Tropical or subtropical low will lift off to the northeast
through mid week allowing for some drying, but looks like
another front will make its way into the carolinas wed. This
front may stall out along or near the coast as high pressure
builds in behind it. The high will track across va on fri,
moving off the nc va coast by Fri night. This should keep an
onshore feed of moisture. This may keep unsettled weather,
especially along the coast through mid to late week.

Aviation 12z Saturday through Wednesday
Frontal boundary seems to be draped over the CWA this morning. Winds
will be light and generally out of the northeast. Time height
indicates moisture will increase throughout the day, with clouds
expected to be in the MVFR ifr range. Convection will increase as
the CAPE slowly increases throughout the day. Coverage will be
fairly widespread by mid afternoon. Showers will continue into the
evening with lowering ceilings.

Extended... Front will likely move just off the coast into
Sunday but lingering moisture likely to lead to additional
restrictions. Also watching potential tropical system moving ne
just off the coast into early next week. Confidence low on
related specifics at this time.

Marine
Changes are underway as a cold front gradually moves into the
region. Winds have already gained a northerly component for most of
our waters, with speeds at or below 10kts. Winds will stay fairly
light through the day and trend more onshore in the afternoon with
the sea breeze circulation. Seas will be around 2ft today. Good
chance of showers and thunderstorms over the waters later today and
tonight associated with cold front. Stronger NE winds and associated
short period seas will develop Sunday as high pressure noses in from
the north and tropical low pressure begins to lift NE from florida.

Some potential for small craft conditions starting late Sunday but
have held off advisory for now as appears to be mainly a Sunday
night 4th period event at this time.

High pressure will run down through the carolinas from the
north as low tracks up through the offshore waters off of the
southeast coast Sun night through early tues. Stiff NE winds
will develop in tightened gradient flow, up to 20 to 25kts sun
night into mon. This will kick seas up to 5 to 6 ft in the outer
waters. Forecast is highly dependent on track and possible
development of tropical or subtropical depression which NHC now
shows as having a 90 percent chc of formation. Seas 4 to 5 ft
sun eve should build to 5 to 6 ft Sun night into mon. Winds and
seas will most likely reach SCA thresholds Sun eve into mon.

This low will lift off to the northeast Mon night into tues with
an off shore flow developing. Seas will diminish heading into
mid week.
