.WHAT HAS CHANGED...
Small Craft Advisory between Cape Hatteras and Ocracoke Inlet
was cancelled due to wave obs below 6 ft.

The threat for dense fog tonight has decreased for far inland
zones but remains likely closer to the coast.

&&

.KEY MESSAGES...
1) Dense fog threat will return tonight and persist for the next
few overnight periods.

2) Well above normal to near record conditions expected
Wednesday through early next week with high pressure ridging
offshore.

&&

.DISCUSSION...
KEY MESSAGE 1...Little change in the overall pattern this
afternoon with the Carolinas remaining under zonal flow and high
pressure, centered over the western Atlantic, expanding over
much of the southeastern CONUS. Dense fog earlier this morning
has since completely burned off over land with very little
evidence of it over area waters on satellite.

Tonight, light to calm winds and low dewpoint depressions will
bring another round of fog. Forecast trends this afternoon have
now favored clearer skies, and thus likelihood of fog formation
has increased slightly from the previous forecast. There is a
stronger signal for dense fog mainly along the Crystal Coast,
perhaps sea fog bleeding onshore, and explicitly show
visibilities down to 1/2 mile here Thurs AM. Fog headlines may
be needed here during the overnight shift.

For planning purposes, sea fog could continue to plague the
coast the next few mornings through this weekend, but the exact
location and intensity is hard to predict this far out.

KEY MESSAGE 2...An anomalously strong ridge remain in place over
the southeastern CONUS into early next week. This will bring
near record temperatures possible for some inland zones some
afternoons, especially tomorrow through this weekend (see
Climate Section below). Highs will reach the upper 70s/low 80s
generally along and west of US 17, and upper 60s/low 70s closer
to the coast. The immediate coast will remain cooler due to very
cold ocean/sound temperatures.

Latest forecast trends show a weak front moving into the
Carolinas late this weekend and into early next week, with the
potential for scattered showers and thunderstorms as the well
above normal conditions hold on.

&&

.AVIATION /00Z THURSDAY THROUGH MONDAY/...
Another round of fog is likely for terminals east of Highway
17 tonight. For EWN and OAJ, LIFR to VLIFR VIS and CIGs are
expected to develop by ~09/10Z as the winds go calm. Dense fog
should gradually dissipate through mid-morning, but CIGs may not
return to VFR until early afternoon. For PGV and ISO, the
chances for fog have decreased. GLAMP MVFR VIS probs are ~20%
around sunrise, so while brief drops are possible, multiple
hours of dense fog is unlikely. Impacts from LIFR to VLIFR CIGs
are more likely for PGV and ISO, but this is not expected to
develop until ~12Z and should return to VFR by early afternoon.
Once conditions return to VFR, scattered low and high clouds
with SW winds at 5-15 kt will finish out the period.

&&

.MARINE...
SEA FOG: A rinse and repeat for sea fog expected tonight with
visibilities dropping over the nearshore waters of Onslow Bay
and the waters adjacent the northern Outer Banks later tonight,
then bleeding into the sounds pre-dawn Thursday. With a stagnant
airmass and little change in the pattern through the rest of the
week, fog formation will likely continue to plague area waters
for the next few mornings. Exact location and intensity will be
hard to predict this far out.

WINDS/SEAS: Only zone with SCA level seas are the central waters
off of Cape Hatteras where seas at Diamond Shoals continue to
hover near 6 feet. This is expected to drop off by dusk, giving
way to good boating conditions tonight with S/SW winds at 5-15
kts through tomorrow. Seas will be mostly 3-5 ft.

Outlook: Pleasant boating conditions continue into this weekend.
Winds generally be 10-20 kts out of the S/SW as high pressure
remains offshore. The pressure gradient will tighten Sunday and
into early next week as a front move into the area, and
winds/seas will approach Small Craft criteria for portions of
the marine area.
