Synopsis
Canadian high pressure building into the mid-atlantic states
will bring several days of cool, dry weather to the carolinas.

Temperatures should begin to warm up this weekend as the high
moves off the coast.

Near term through tonight
As of 10 am Wednesday... Surface high remains north of the area
into tonight with northeast winds gradually decreasing as the
gradient slowly weakens. Some low clouds, associated with an
area of higher rh at the base of the subsidence inversion,
managed to move onshore this morning. These clouds have mixed
out, leaving clear skies for the rest of today. Highs will end
up right around climo despite a chilly start. Only minor tweaks
needed for the morning update.

Short term Thursday through Friday night
As of 300 am Wednesday... A 500 mb ridge over the lower
mississippi valley Thursday will build over the carolinas on
Friday. This should push the surface high from the southern
appalachians into the northeastern u.S. A pronounced
subsidence inversion descending to as low as 3000 feet agl
should help keep skies clear.

It's a pretty unremarkable weather pattern. 850 mb temps will
recover through the period from around +10c Thursday morning to
around +14c by Friday. While the subsidence inversion aloft
should guarantee we won't mix all the way up to 850 mb, it still
appears we'll see upper 70s for highs both days, with perhaps
an isolated 80-degree reading Friday. Morning lows should range
from the upper 40s-lower 50s Thursday night to the lower-mid
50s Friday night.

Long term Saturday through Tuesday
As of 300 pm Tuesday... It will remain high and dry into Sunday
as high pressure remains in control of area weather. An
approaching cold front and return flow around the high will
bring increasing clouds Sunday and Sunday night with a small
chance of showers. Chances for showers will continue Monday and
Tuesday as the front moves into and through the area. Max
temperatures Friday through Monday will be in the upper 70s to
around 80 and in the mid 70s Tuesday. Minimums will moderate
from the low to mid 50s Friday morning to the low to mid 60s
Monday and Tuesday morning.

Aviation 14z Wednesday through Sunday
As of 12z... High confidence forVFR through 19 12z with ne
winds and sct clouds. Latest satellite indicates cirrus west of
kflo klbt with marine stratocumulus mostly offshore. There will
be a potential for lowVFR stratocumulus CIGS at kilm at times
this morning and by 19 10z but confidence is low.

Extended outlook... Tempo MVFR showers Monday. OtherwiseVFR.

Marine
Near term through tonight ...

as of 10 am Wednesday... Surface high to the north will maintain
a tight gradient over the waters into the afternoon. Pinched
gradient will keep winds a solid 20 kt with seas across the
outer edges of the marine zones, except amz254, running 6 ft
today. Small craft advisory continues through the afternoon with
a scec in effect for amz254. Gradient will gradually weaken
during the late afternoon and early evening hours with both
winds and seas gradually decreasing.

Short term Thursday through Friday night ...

as of 300 am Wednesday... High pressure will remain across the
mid-atlantic states Thursday through Friday. A weak wave of low
pressure will develop in the open atlantic northeast of the
bahamas on Thursday, quickly shooting northeast and away from
the united states. This feature will help keep the pressure
gradient tight enough on Thursday for 15-20 kt northeast winds
in the morning, but wind speeds should diminish Thursday
afternoon and night, and by Friday morning should be 10 kt or
less. Seas should likewise subside through the period.

Long term Saturday through Sunday ...

as of 300 pm Tuesday... Winds will gradually become easterly by
Sunday morning then southeast by Sunday night. Seas 2 to 3 ft
Saturday then increase to 3 to 5 ft by Sunday evening.

Tides coastal flooding
As of 10 am Wednesday... Astronomical tides will peak with the
new moon on Thursday. High tides and strong northeast winds may
combine to push tides above minor coastal flooding thresholds
at wrightsville beach and the lower CAPE fear river to include
downtown wilmington. Advisories may be needed around the time
of high tide through Friday.

Ilm watches warnings advisories
Sc... None.

Nc... None.

Marine... Small craft advisory until 6 pm edt this evening for amz250-
252-256.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
