Synopsis...
high pressure settles over the Middle Atlantic States today through
Saturday. A dry cold front moves across the region Saturday night.
High pressure builds back into and over the area for Sunday and
Monday.

&&

Near term /until 6 PM this evening/...
low pressure will continue to spin off the New England and Canadian
Maritimes csts today into this eveng...as hi pressure builds into the
area from the Ohio Valley. Under a mostly sunny...maximum temperatures will range
from the upper 60s to lower 70s.

&&

Short term /6 PM this evening through Sunday/...
hi pressure will build over the region and just offshr tonight through
Sat...maintaining dry autumn weather. Clear/mostly clear tonight with lows
ranging through the 40s. Mostly sunny on Sat with highs in the upper
60s to lower 70s. A weak/dry cold front will cross the area Sat night.
This front will do little more than increase winds from the northwest on
sun...while lots of sunshine will continue. Lows Sat night ranging
from the middle 40s to lower 50s. Highs on sun ranging from the upper 60s to
middle 70s.

&&

Long term /Sunday night through Thursday/...
a weak trough will be well to the southeast Sunday night as high
pressure settles over the region on Monday and then slides off the
coast Monday night through Wednesday. Overall conditions will be
dry/rain-free. As the ridge axis shifts eastward...temperatures will begin
to warm into the low-middle 70s during the day. Overnight temperatures will
likely experience a much slower warming trend with low temperatures in the
40s Sun night (low-middle 50s beaches)...in the middle 40s to lower 50s
Monday night (mid 50s beaches)...and in the 50s Tuesday night. The next
cold front to impact the middle Atlantic region is expected to cross
the area late Wednesday night. Expect continued warm temperatures with
breezy southwest winds and increasing cloud cover as Wednesday
progresses.

&&

Aviation /18z Friday through Wednesday/...
VFR conds will persist through the 18z taf period. High pressure
noses into the area creating light winds and dry conditions. A weak
upper wave will pass over the area Sat...bringing only some high clouds
to the mid-Atlantic.

Outlook: a dry cold front makes its way across the eastern US by
Sunday morning. VFR conds continue to persist Sat through early next
week as high pressure builds over the region.

Marine...
latest observation reflect northwest flow across the waters ~15-20kt. Seas 3-5ft
(highest north) with waves 3ft on the ches Bay. Vert stacked,
deepening low pressure will continue to lift NE towards Atlantic
Canada through early afternoon. Meanwhile, surface high pressure will
build west of the waters today. Resultant pressure gradient will
slowly slacken today as high builds into the region, resulting in
gradually diminishing northwest winds through tonight. Small Craft Advisory flags come
down by afternoon over the Sound/Bay. Over the coastal waters,
winds will diminish with aforementioned slackening gradient. Given
that wind waves are keeping seas elevated this morning, expect
seas/waves subside through the day. Expect pressure gradient will be
slowest to relax over the far northern waters. Thus, have held
onto Small Craft Advisory flags until early evening north of Chincoteague, with Small Craft Advisory
flags dropping farther south by this afternoon.

A weak trough passes across the waters on Saturday, with sub-Small Craft Advisory
winds out of the north-northwest expected to back around to the SW Saturday afternoon
in response to the approaching trough. Winds then veer back to the
northwest after it crosses the area Sat night/Sunday morning. Only a modest
Post frontal cold air advection surge Sunday, so expect winds to average at or below 15 kt,
though a brief period of Small Craft Advisory will be possible late Sunday and Sunday
night as high pressure builds in from the west. Winds shift to the
east-southeast by late Monday as high pressure settles over the
waters...eventually sliding farther offshore Monday night through
midweek.
