SCT-BKN MVFR CIGS cont across the area as the upr level low

Clouds decrease w-e late tonight and Thurs as high prs builds
into the area.

into Fri afternoon w/ flight restrictions likely due to lower
BKN-OVC CIGS and SHRAS. Mainly VFR conditions expected Sat-Sun.

.MARINE...
As of 330 PM EDT Wednesday...

SCA Headlines remain in effect through 1 am Thu for the mouth of
the Bay, and well into Thu aftn for all coastal waters due to
lingering long period E/SE swell of 10-12 seconds. Seas
currently avg 6-8 ft with waves to around 4 ft at the mouth of
the Bay.

Broad low pressure moving into the Delmarva this aftn and will
continue to lift NE into New Jersey this evening through
tonight. Winds are relatively light with S to SE flow around 10
kt or less (light/variable in some areas). Winds will shift to
the W to NW at around 15 kt later tonight into Thu morning.
While some occasional 20 kt gusts will probably develop for a
few hrs early Thu morning across much of the area (especially
in the Bay N of New pt Comfort), does not look to be enough to
warrant SCA headlines since there is minimal cold advection in
the wake of this cold front. Weak sfc high pressure builds in
fm the NNW on Thu, with winds diminishing by late morning and
shifting back to onshore during the mid/late aftn hrs through
Thu evening. Another low pressure area will affect the waters
Thu night thru Fri, as it tracks from the SE U.S. through the
local area on Fri and off to the NE by Fri night. Another cold
front crosses the waters Sat night, increasing winds close to
SCA levels, then diminishing Sun as high pressure returns.
