Synopsis
High pressure will prevail through the middle of next week. A
weak cold front will drop into north carolina late Sunday into
early Monday. The high will shift offshore and as a trough of
low pressure approaches from the east Tuesday, resulting in a
chance for showers and thunderstorms. A cold front will approach
the region from the northwest later next week.

Near term through tonight
As of 300 am Friday... High pressure extending down from the
north will migrate slowly southward orienting itself over the
carolinas with center almost directly overhead by tonight. The
mid to upper ridge will also be overhead providing plenty of dry
air and subsidence. This will keep showers at bay through
tonight. Unfortunately as conditions remain dry, rivers will
continue to rise and extensive flooding will continue as the
flood wave makes its way down along some of the major rivers.

Overall expect plenty of sunshine with temps in the mid 80s most
places.

Decent radiational cooling will occur tonight with clear skies
and diminishing on shore winds becoming near calm winds as high
pressure moves overhead, leading to temps in the mid 60s most
places and fog, patchy this morning and a bit more widespread
tonight as the high reaches overhead.

Short term Saturday through Sunday night
As of 345 am Friday... Mid level high pressure will dominate this
period. At the start of this period, the high will be nearly
overhead, then is progged to push off the carolinas and offshore by
the end of this period. The "push" is from the expanding polar
westerlies aided by progressive mid-level S W trofs that basically
bypass just north of the fa. The sfc cool front dropping southward
is progged to stall just north of the ilm cwa. The sfc high behind
the cool front will try to expand down the east coast of the u.S.,
however the CAA will be lacking this far south. Pops will be
isolated at best for sat, the peak of the upper ridging. For sun
thru Sun night, have indicated pops ahead of the cool front possibly
reaching the northern portions of the fa. Pops from a progressing
easterly wave will reach the ilm CWA coast by the end of this
period. Thus, the hiest pops in the short term will be occurring at
the end of this period. Stayed with a MOS guidance consensus with
both MAX and min temps.

Long term Monday through Thursday
As of 320 pm Thursday... High pressure at the surface will shift
off the coast. Onshore flow will begin to increase the moisture
on Sunday as a frontal boundary stalls well to the north of our
area. What this means is chance for showers and thunderstorms
increases to the 30 to 40% chance of diurnal showers through
Wednesday. A cold front approaches the area from the west on
Thursday.

High temperatures will be in the 83 to 87 degree range with lows in
the upper 60s inland to the lower 70s at the coast.

Aviation 06z Friday through Tuesday
As of 06z... Clear skis and calm winds will lead to decent
radiational cooling and possibility of fog 9z-12z tonight, mainly
inland tafs, lbt and flo. Light onshore flow overnight could lead to
some additional moisture advection that could promote fog or stratus
at the coastal terminals as well, although confidence is low for
this scenario as guidance does not reflect this. Tomorrow should be
similar to today, clear to sct skies as high pressure dominates
withVFR at all TAF sites.

Extended outlook... MostlyVFR through this period. However, flight
restrictions are possible in late night early morning fog stratus,
and brief flight restrictions are possible within showers
thunderstorms Sunday through Tuesday, especially during the
afternoon evening hours.

Marine
Near term through tonight ...

as of 300 am Friday... Quiet marine conditions through tonight.

Expect light onshore flow as high pressure extending down from
the north migrates southward over the carolina coast. Winds will
shift from a more NE direction to e-se by tonight, becoming more
variable as they lighten up tonight. Seas near 3 to 4 ft
overnight will diminish through the day to 3 ft or less by
tonight. Should see a little spike and some gusts in winds in
afternoon sea breeze near shore.

Short term Saturday through Sunday night ...

as of 345 am Friday... Weak sfc high pressure centered nearly
overhead at the start of this period, will keep winds relatively
light, ie. 10 kt or less. Sfc cool front dropping southward will
stall north of the area waters before washing out by the end of this
period. 1037mb sfc high pressure centered over SE canada will expand
southward down the east coast of the u.S. By the end of this period.

This will result with continued onshore winds but with speeds
increasing-some by the end of this period due to the sfc pg
tightening. Significant seas will run 2 ft or less at the start of
this period. As the onshore winds become better established along
with increasing fetch, sig. Seas will be in a building phase. By the
end of this period, seas will be a solid 3 ft with a few 4 footers.

Dominant periods will run 8 to 10 second periods. Swell direction at
the start will be from the NE and by the end of this period, more
easterly. Showers and a few storms may affect the local waters by
the end of this period, due to an approaching easterly wave.

Long term Sunday through Monday ...

as of 320 pm Thursday... High pressure will remain over the
waters through Monday with a cold front stalling to the north of
the waters Monday. Winds will be northeast to east through the
period around 10 to 15 knots. Seas will run between 2 to 4 feet.

Tides coastal flooding
As of 300 am Friday... High tides for the next several days
could see renewed flooding downtown as the main flood wave on
the CAPE fear river reaches town, combined with astronomical
high tides. River levels should reach moderate and possibly
even major flooding as we approach the full moon over the next
several high tides.

Ilm watches warnings advisories
Sc... None.

Nc... Coastal flood warning until 11 am edt this morning for
ncz107.

Marine... None.

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