Synopsis
Cool high pressure will build in from the north today before
moving offshore Saturday. Warmer weather is expected Sunday
ahead of a cold front, that will cross the coast during Sunday
evening. High pressure will build in through early next week.

Near term through Saturday
As of 333 am Friday... Temperature trends today will look like
nighttime traces, with falling air temperatures in wake of a
cold front amid moderate cold air advection. Dewpoints to drop
into the 40s with 10-meter winds peaking between 18z-00z, 11-13
knots sustained on average. The cooling into already saturated
air will result in occasional drizzle, while frontal convergence
helps to spur a few showers, and enhance isentropic lift aloft.

The low QPF pattern continues as stronger upper forcing remains
well N and W of the area, but a damp period today and tonight
with wetting expected, and favored from NW to SE respectively.

Max-t forecasts show a substantial gradient of temperatures due
to the front, middle 50s northern SE nc, to middle 60s interior
ne sc. Saturday over-running atop cool air damming, but again,
heavier rainfall to remain nw-n of the area, the enough to have
clouds and damp conditions, and occasional -ra dz due to the
near saturated air.

Short term Saturday night through Sunday night
As of 333 am Friday... Seemingly endless moisture laden pattern
will finally be on the move through the short term period. One
last (at least for a while) potent mid level storm system will
be moving through the middle mississippi valley which will push
a cold front through the area late Sunday into early Monday.

Decent pops with the front but most of the connection to the
gulf of mexico is waning and for now likely values will suffice.

Yet another very warm day Sunday but cooling off by Monday
morning.

Long term Monday through Thursday
As of 333 am Friday... Mostly dry through the first part of the
extended period with temperatures at or just above climatology.

A diffuse and broad system may bring the next chance of showers
to the area mid week on but the system doesn't look too
organized at this point and relatively low chance pops remain in
the forecast.

Aviation 16z Friday through Tuesday
As of 18z... Surface ridge wedge has set up once again with some
light showers overrunning the cool air. Look for ifr conditions to
prevail for most of the forecast period. A brief window of MVFR
conditions is possible this afternoon, becoming ifr once again this
evening. Ifr conditions are expected to last through the end of the
forecast period.

Extended outlook... Sub-vfr will likely prevail early Sunday before
another cold front pushes through lifting toVFR late Sunday through
Wednesday.

Marine
As of 333 am Friday... Roughening seas forthcoming in wake of a
cold front as NE winds increase to 20 kt, and seas near 6 feet
offshore and north of CAPE fear by late today. An SCA may be
needed, but will access sea heights for the daybreak updates to
see if SCA flags are needed. Residual SE swell will be overtaken
and masked by increasing shorter crest NE wind-seas today. This
will produce steep seas. Winds to ease Saturday, seas
recovering only slowly so expect heights of 4-5 ft offshore even
Saturday with periods of 6-7 seconds. Fog to plague the waters
this morning until drying later today, and a marine dense fog
advisory is posted this morning, thickest fog inshore.

The strongest winds and highest seas will occur ahead of
the cold front Sunday. A southwest flow of 20-25 knots will develop
for a good part of the day. Significant seas will eclipse small craft
criteria during this time as well. Beyond this high pressure will
build in but without strong cold air advection, the winds will be
somewhat modest, well below any flag criteria, same for seas.

Ilm watches warnings advisories
Sc... None.

Nc... Coastal flood advisory until 1 pm est this afternoon for
ncz107.

Marine... Dense fog advisory until noon est today for amz250-252-254-256.

Small craft advisory until 6 am est Saturday for amz250-252.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
