Synopsis
High pressure will build in from the northwest today. Another
cold front is expected to move through the area this weekend,
followed by dry and cool conditions early next week.

Near term until 6 pm this evening
As of 1200 pm Thursday... Late morning update mainly captured
t TD trends. Surface analysis shows a 1035 mb high over the
midwest states this morning and will drift southeast during the
day. A decent pressure gradient continues late this morning
producing breezy conditions with gusts around 20-25 mph, but
winds will relax during the afternoon as the high becomes closer
to enc. Low level thicknesses is expected to drop about 40
meters and 850 temps around 7c 8c, bringing highs in the low to
mid 60s inland, to mid 60s by the coast.

Short term 6 pm this evening through 6 am Friday
As of 315 am thurs... The high will continue to slide towards nc
and become overhead after midnight. Winds will become
light calm under clear skies, resulting in good radiational
cooling during the overnight. Expect chilly overnight
temperatures around 39 to low 40s inland to low 50s along the
coast.

Long term Friday through Wednesday
As of 3 am Thursday... The period will begin with deep layer ridging
in control locally as an upper trough digs across the northern
plains into the midwest. At the surface, high pressure will pass
directly overhead, keeping skies clear and calm conditions in
place Friday.

By Friday night, h5 heights will begin to fall locally in response
to the approaching trough. At the surface, warm air advection will
increase ahead of an approaching cold front. Pwats will surge to
near 1.75 in during the day Saturday, with unsettled weather
prevailing as the main band of prefrontal moisture moves over the
area. Thermodynamic instability will be at a premium, but storm
coverage will still be widespread owing to the dynamic enhancement
from dpva and low level moisture convergence. The cold front will
cross the area late Saturday into early Sunday.

The upper trough axis will pass overhead early Sunday morning and
deep layer subsidence will ensue through early next week. Strong
cold air advection will begin Sunday as robust canadian high
pressure builds in, with gusty northerly winds bringing 850 temps
that are 2 to 3 standard deviations below normal Sunday night Monday
morning.

Surface high pressure will dominate through the first half of next
week, with below normal temps persisting. A shortwave could pass
overhead Tuesday into Wednesday, but dry low to mid levels will
preclude much of a precip threat with this feature.

Aviation 16z Thursday through Monday
Short term through Thursday ...

as of 700 am thurs... High confidence inVFR conditions will
dominate the TAF period as high pressure builds over the region
from the north. Winds will increase after the Sun rise to around
10 knots with gust at times to 20 kt through the afternoon.

Winds will become light again tonight under clear skies.

Long term Friday through Monday ...

as of 330 am Thursday...VFR conditions will prevail Friday.

Periods of ceiling and visibility restrictions are possible
Saturday and Saturday night as an approaching cold front brings
unsettled weather.VFR conditions will return Sunday, prevailing
through early next week.

Marine
Short term through Thursday ...

as of 12 pm Thursday... N NE surge is peaking across the waters
late this morning and early afternoon with winds up to 20-25 kt
with gusts up to 30 kt. With winds starting to subside and gusts
now less than 25 kt across the albemarle sound alligator river
and inland rivers have dropped the SCA in these locations. Will
continue across the pamlico sound and coastal waters where
winds and or seas still to SCA criteria.

Conditions will continue to slowly improve this afternoon as
cold advection weakens... Leading to winds diminishing to 15-20
knots and seas diminishing slowly diminish through most of the
afternoon as seas become below 6 ft this evening. Expect
conditions to further improver during the overnight hours with
winds becoming NE 10-15 knots and seas 2 to 4 ft.

Long term Friday through Monday ...

as of 330 am Thursday... Friday will feature benign marine conditions
as high pressure passes directly overhead. Southwest winds will
begin Friday night, increasing to 15 to 20 kt Saturday, with gusts
approaching 25 kt possible. A strong cold front will cross the
waters late Saturday into Sunday, with winds quickly shifting to
northwesterly and becoming gusty behind the front - Sunday into
Sunday night. A small craft advisory may be needed Saturday, and
will almost certainly be necessary Saturday night and Sunday. Winds
will gradually decrease Sunday night into early next week as high
pressure fills in. No significant incoming swells are expected
through the period, so seas wind swell will generally rise and fall
with local winds speeds.

Mhx watches warnings advisories
Nc... None.

Marine... Small craft advisory until 4 pm edt this afternoon for amz135-
156-158.

Small craft advisory until 8 pm edt this evening for amz150-
152-154.
