Synopsis
High pressure will build in from the north on Friday, before
sliding offshore on Saturday. Warm weather is then expected
Sunday ahead of a cold front that moves off the coast Sunday
evening. High pressure returns early next week.

Near term through Friday night
As of 315 pm Thursday... Much of the forecast area has broken out of
the stratus fog and temperatures have quickly responded with a few
areas in the mid and upper 70s. Enough of a temperature gradient has
developed to allow a sea breeze to form, which has helped keep
temperatures down along the immediate coast. Otherwise, flat h5
ridging prevails across the southeastern united states with dry
mid upper air in place per water vapor imagery. In addition, the
subtropical jet is spreading deeper moisture across mexico and tx
into the plains, and the ms and oh valleys. Although the subtropical
jet will shift toward east during the near term period the overall
pattern aloft will remain somewhat unchanged across the southeastern
states.

At the surface, a cold front will drop south across the forecast
area later tonight across the southeast nc zones and during Friday
morning across northeast sc zones. Stratus fog is expected to
develop again this evening ahead of the front, possibly becoming
dense at some locations. The chance for showers will increase
tonight into Friday with uvvs overspreading the area in
southwesterly flow aloft and development of isentropic lift.

However, the higher QPF amounts are expected to be much farther west
and northwest of the forecast area through Friday night. Otherwise,
atypically warm overnight temperatures with temperatures falling
during Friday in the wake of the front will not for much in the way
of a diurnal range, especially for the northern half of the forecast
area.

Short term Saturday through Sunday
As of 330 pm Thursday... High pressure north of the area Friday
night slides offshore on Saturday, but the high is quite strong
and the cad setup over the local area should last through much
of the day except near the coast where temps may reach 60;
highs the 50s elsewhere. As far as rain chances... Any precip
will be light and mainly confined to northern areas in the
morning hours. Fairly stagnant or even slowly rising temps into
Saturday night ahead of an approaching cold front. This front
crosses the area late Sunday, and any rain amounts will be quite
light due to the best forcing and moisture profiles staying
north of the local area. Highs mainly in the low mid 70s.

Long term Sunday night through Thursday
As of 330 pm Thursday... Dry weather returns to start the long
term period as surface high pressure builds in from the west.

The high slides offshore through midweek, as chances for rain
rise due to increasing warm air advection. Temps through the
period will be close to normal for late february... Highs in the
60s with lows in the upr 30s to upr 40s.

Aviation 20z Thursday through Tuesday
As of 18z... Conditions are gradually improving across the area
as the wedge erodes. Ifr MVFR CIGS will continue for a couple
more hours at kflo klbt. The return of ifr CIGS is likely
tonight with ample low-level moisture and light winds ahead of
the next cold front. Chances for -dz ra will also increase
overnight.

Extended outlook... Front lingering in the area will lead to
more ifr ceilings and or vsbys Friday into Saturday as another
round of overrunning rain develops. Sub-vfr will likely prevail
early Sunday before another cold front pushes through lifting
toVFR late Sunday and Monday.

Marine
As of 315 pm Thursday... Per satellite imagery shallow sea fog
continues across the adjacent coastal waters. Local procedures and
hrrr indicate that sea fog will likely continue tonight into Friday
morning, generally south of the cold front as it moves through. The
current dense fog advisory is in effect through 4 pm and it may
need to be extended or re-issued for tonight.

The pressure gradient will remain weak ahead of the aforementioned
cold front. The front should clear the southernmost waters Friday
afternoon. A strong northeasterly pressure gradient will prevail in
the wake of the front as high pressure noses in from the north. The
strong northeasterly winds will persist Friday into Friday night with
a coastal trough taking shape by early Saturday morning. Seas will
be 3 to 5 ft in weakening swells this afternoon into tonight.

Steeper higher frequency waves are expected as the northeast fetch
becomes established Friday into early Saturday morning. A chance of
showers will also exist tonight into early Saturday morning.

Winds seas slacken a bit into Saturday as a coastal trough
locates in the vicinity. 6 ft seas possibly return Sunday ahead
of an approaching cold front, which crosses the waters late
Sunday. High pressure and improving marine conditions then into
early next week.

Tides coastal flooding
As of 315 pm... Minor coastal flooding is possible, especially with
the next couple of high tide at downtown ilm. Water levels will
likely fall a little short of thresholds for wrightsville beach.

Thus plan to issue a coastal flood advisory only for downtown ilm
with high tide later this evening.

Ilm watches warnings advisories
Sc... None.

Nc... Coastal flood advisory from 8 pm this evening to midnight est
tonight for ncz107.

Marine... Dense fog advisory until 7 am est Friday for amz250-252-254-
256.
