KEY MESSAGE 1...Seasonable temperatures and dry through Monday,
then rain chances return late next week.

Strong surface high remains in place across the region through the
start of next week. Seasonal temperatures and dry conditions are
expected through Monday as highs reach the 60s, and lows settle in
the upper 30s to 40s each day. Passing high cirrus today gives way
to more mid-level cloudiness Sunday due to a shortwave trough that
slides south of the region. The surface high moves offshore Monday
and remains centered east of the Mid-Atlantic coast through the
middle of next week. Return of east to southeast winds bring a
gradual warming trend next week that has highs reach the low 70s on
Tuesday, though still remaining dry.

A deep upper level trough pivots eastward from central CONUS on
Wednesday, with precipitation chances returning to the forecast
area. At the surface, a low pressure system tracks from the
Mississippi River valley towards the Mid-Atlantic the second half of
the week. As the system approaches, precipitation chances increase
and are expected to linger through the end of the week. The best
chance for widespread rain is on Thursday afternoon into Friday, as
the low pressure system passes nearby. Surface high pressure builds
overhead in the wake of the low pressure system, with diminishing
rain chances expected. High temperatures will be in the upper 60s to
low 70s east of the Blue Ridge with those along and west in the
upper 50s to 60s. Overnight low temperatures will be in the 50s each
night. Lows drop into the 40s east of the Blue Ridge Thursday and
Friday night.

.AVIATION /18Z SATURDAY THROUGH WEDNESDAY/...

VFR and dry conditions are expected to prevail through the middle of
the upcoming week. High pressure over the region will maintain light
north winds today that gradually turn east to southeast Sunday, then
remain south through Wednesday. The next chance for showers could
arrive Wednesday night, but conditions likely still remain VFR.

&&

.MARINE...

Northerly winds gusting around 10-15 knots this afternoon will
gradually become light to calm this evening into tonight as high
pressure settles over the region. The high begins to move offshore
Sunday, then remains centered over the western Atlantic through the
middle of next week. Light east to southeast winds on Sunday become
southerly for much of next week. Southerly channeling effects could
cause some increase in winds come Wednesday.
