.SYNOPSIS...
High pressure builds overhead today before shifting offshore Friday
and Saturday. A warm front will lift through the region on Friday,
ahead of a cold front moving through Saturday night through Sunday.
A low pressure system moves to the north early next week with
high pressure briefly returning midweek.

&&

.NEAR TERM /THROUGH TONIGHT/...
High pressure builds overhead today with mostly sunny skies, warming
temperatures, and dry conditions expected. High temperatures will be
in the mid 50s to 60s across the area with overnight lows dipping
into the 40s. Cloud cover increases this evening and through the
overnight as high clouds move in due to a warm front approaching
from the southwest.

&&

.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
As surface high pressure shifts offshore, return flow ushers in warm
air from the south and increased moisture. A warm front is forecast
to lift through the forecast area on Friday as a cold front
approaches from the west.  Gradually warming temperatures can be
expected Friday and Saturday, along with increased cloud cover. High
temperatures on Friday will be in the 70s for most with those at
higher elevations staying in the 60s. On Saturday, high temperatures
will be in the 80s for most with those at higher elevations staying
in the 70s.

In addition to gradually warming temperatures, a low pressure system
will track NE from the Great Lakes on Saturday with the associated
cold front set to approach the forecast area from the Ohio
River Valley. As the cold front approaches, precipitation
chances in the northwestern portions of the forecast area
increase.

&&

.LONG TERM /SUNDAY THROUGH THURSDAY/...
Deep ridging just off the Southeast U.S. coast on Sunday will drift
offshore into the start of next week. The strength of this ridge
likely keeps an approaching cold front well to our north, though a
weak disturbance aloft could result in a few showers west of the
Blue Ridge Sunday afternoon. Otherwise, a mostly dry and warm end to
the weekend as highs reach the mid 70s to low 80s.

A strong upper trough and associated surface low pressure will move
across the Midwest/Upper Great Lakes on Monday. As the low pressure
system pulls away into Canada, the attached cold front is forecast
to move across the Mid-Atlantic Monday afternoon into Monday night.
Given weak forcing and lingering dry air, rain chances look to be on
the lower side at this time (30-40pct). High pressure builds in
quickly behind the front Tuesday into Wednesday, likely bringing
another few days of dry conditions.

Temperatures are forecast to be above normal into next week. Highs
reach the mid to upper 70s each day, with 60s in the mountains, and
around 70F along the MD/PA border. Overnight lows mostly in the 50s,
with 40s in the mountains.

&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
VFR conditions are expected today through Saturday as high
pressure builds overhead before shifting offshore. Winds become
light and variable tonight before shifting to southerly on
Friday, gusting 15 to 25 knots in the afternoon. Winds diminish
slightly on Saturday, blowing out of the southwest at around 10
knots.

VFR conditions are likely Sunday into Monday. Scattered showers
possible Monday evening into Monday night, but coverage and
intensity look to be low enough to prevent any significant
disruption to the local terminals.

&&

.MARINE...
Sub-SCA criteria winds continue overnight across all waters.
Winds increase Friday morning due to southerly channeling with a
Small Craft Advisory in effect beginning at noon. Southerly
winds blowing between 15 and 20 knots with gusts up to 25 knots
are expected. SCA criteria condtions are possible again on
Saturday.

Favorable marine conditions Sunday into the start of next week as
high pressure south of the area remains in control. Winds are
expected to shift from north to east, then southeast on Monday, all
at 5-10 knots. A slight increase in winds is possible Monday night
as gusts increase to around 15 knots, especially in the middle
Chesapeake Bay.
