National Weather Service Wilmington NC
654 PM EDT Friday may 22 2015

high pressure and much drier air will build into region and
continue into the weekend. High pressure will shift offshore early
next week with higher humidity levels returning to the area.


Near term /through tonight/... as of 630 PM Friday...just a
beautiful evening across the area. Cold front is well south of the
area...and diurnal cumulus which developed along a weak sea breeze is
melting away. This will leave a clear and cool night across the
Carolinas as high pressure extends east from the MS valley. The cool
dry atmosphere will allow for good radiational cooling...and have
sided on the cooler side of guidance with lows a little above 50 in
the northwest around 55 along the South Santee River.


Short term /Saturday through Sunday night/...
as of 315 PM Friday...500 mb trough exiting New England Saturday will
allow heights to increase during Sunday as the 500 mb ridge axis slides
east from the MS valley. Meanwhile...the surface pattern will be
dominated by high pressure migrating off the coast of Delaware-Maryland-Virginia.
Onshore wind each day will hold maximum temperatures back each
day...while inland areas warm into the 80s. Sunday will be the
warmest day of the weekend with mostly clear skies through the
period. Min temperatures will be a little below normal each night...
especially across the inland stations. No probability of precipitation with little to no
moisture to work with in the 850 mb-5 layer.


Long term /Monday through Saturday/...
as of 315 PM Friday... middle level ridging will dominate the extended
forecast. Medium range guidance does show some indications of the
feature breaking down very late but with weak troughing appears the process will be slow. At the surface high
pressure prevails as well. We continue to carry slight chance probability of precipitation
on a diurnal basis for Wednesday through Friday but even this seems
a stretch. Warming will be slow although persistent with guidance
showing highs near 90 inland and the middle 80s along the coast.
Overnight lows will generally be north of 65 degrees.


Aviation /00z Saturday through Wednesday/...
as of 00z...VFR ceilings are possible early this evening at the coastal
terminals...but for the most part clouds will be on the decrease
with VFR and clear skies expected through Saturday morning. Winds
will become light and variable by early this evening. 3-5 degree
temperature/dew point spreads with drier air just off the surface in the
pre-dawn hours suggest little if any potential br issues.

VFR Saturday with NE winds in the am becoming east-southeast in the afternoon.

Extended outlook...VFR. Morning fog possible Monday and Wednesday.


Marine... near term /through tonight/...
as of 630 PM Friday...high pressure settling across the waters will
continue to drive calm marine conditions through tonight. Slightly
elevated winds along the sea breeze in the near shore waters will
fade quickly with nightfall...and winds tonight will settle on a
north/NE direction with 5-10 knots speeds. This will drive wave heights of
2-3 feet...slightly less in the shadowed region SW of Brunswick County.

Short term /Saturday through Sunday night/...
as of 315 PM Friday...high pressure off the Delaware-Maryland-Virginia coast Sunday
will result in easterly flow across the adjacent waters of northeast
SC and southeast SC. The high will push farther offshore during
Sunday allowing east to southeast flow to prevail. Seas will range
from 2-3 feet inshore to 3-4 feet farther offshore each day.

Long term /Monday through Wednesday/...
as of 315 PM Friday...Bermuda high pressure will bring a full
fledged summertime pattern to the coastal waters through the period.
Expect southeast winds of 10-15 knots with the highest values
occurring during the afternoons courtesy of the sea breeze
acceleration. Significant seas will generally match the winds with 2-
3 feet.
