.SYNOPSIS...
A cold front will move through overnight. High pressure briefly
builds over the forecast area on Wednesday ahead of a warm
front lifting through the region on Thursday. A cold front
pushes through the forecast area overnight into Friday before
stalling to the south. Another cold front impacts the region
this weekend.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
A clipper low will track southeastward across southern
Quebec/Ontario and Northern New England overnight. Meanwhile, an
area of high pressure will build eastward across the western
Great Lakes. At the surface, a weak cold front will move through
the area.

Skies this evening have cleared out across the Virginia
Piedmont, but a mix of high clouds and lower-level stratocumulus
remain in place across much of the rest of the forecast area.
The trend through the night should be for both the low and high
cloud cover to decrease in coverage, with the exception of
locations to the west of the Allegheny Front (where upslope flow
will maintain cloud cover). Dry conditions are expected for
all, with overnight lows in the 30s and 40s.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/...
Surface high pressure briefly builds over the region on
Wednesday with dry conditions and limited cloud cover expected
through the morning. High temperatures will range from the low
40s in northern Maryland to low 60s in central Virginia. Cloud
cover begins increasing in the afternoon with mostly cloudy
skies expected overnight. Low temperatures will drop into the
30s across the area.

A shortwave trough approaches and pivots overhead Wednesday
night into Thursday, bringing increased precipitation chances. A
chance of precipitation begins early Thursday morning with a
rain/snow mix is possible along and east of of the Blue Ridge
with the leading edge of precipitation. By sunrise,
precipitation type will be all rain as temperatures warm above
freezing areawide. Temperatures will be quite marginal hovering
right at or slightly below freezing so uncertainty remains
regarding precipitation type. Either way, no impacts from wintry
weather are expected.

Cloud cover lingers throughout the day on Thursday as
precipitation moves out of the area in the afternoon. A
temperature gradient continues with high temperatures ranging
from mid 40s in northern Maryland to low 60s in central
Virginia.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
Models continue to advertise the possibility of a winter storm on
Friday, particularly for locations north of I-66/U.S. 50. A
preponderance of the 12Z guidance favor an area from I-70 northward
across the Mason-Dixon Line into Pennsylvania. The setup is
certainly favorable for a wintry mix dominated by freezing rain and
sleet. Canadian high pressure builds over Quebec while a stationary
boundary arcs west to east across the Carolinas. The resultant cold-
air damming (CAD) signature is quite favorable to such setups. Low-
level cold air becomes locked in place while warm advection above
this layer ushers in milder air aloft into the (925-850 mb layer).
Models are also hinting at some snow toward northern Maryland given
colder thermodynamic profiles. All and all, travelers will need to
consider this potential winter storm in their plans for Friday.
Aside from this precipitation threat, it will be a chilly day across
the region with highs in the 30s to low 40s (40s along the
Alleghenies).

The focus for wintry precipitation begins to shift toward
northeastern Maryland on Friday night. Eventually this becomes a
cold rain for the second half of the night as slightly milder air
works into the picture. Forecast lows will range from the upper 20s
to 30s.

With the frontal zone to the south, some moisture will continue to
overrun this boundary on Saturday. While precipitation chances
become more limited, clouds should be plentiful. This comes with
highs in the upper 30s to mid 40s north of I-66, to mid 40s to
50s off to the south. A stronger system arrives on Sunday which
yields rain chances amidst high temperatures in the upper 40s to
50s (low 60s across the I-81 corridor and Allegheny mountain
valleys). A pronounced cool down ensues behind this strong upper
trough. By early next week, highs will fall back into the 30s
with teens to 20s across the mountains. Moisture is rather scant
so upslope snow showers are somewhat unknown along and west of
the Alleghenies.

.AVIATION /01Z WEDNESDAY THROUGH SUNDAY/...
VFR conditions continue overnight as winds increase in the wake
of a cold front. West/northwest winds start out light this
evening before gradually increasing from west to east overnight.
Low-level wind shear may also be possible late tonight. Winds
gust 15 to 25 knots Wednesday morning across all terminals with
the exception being KCHO where light winds are expected. Winds
diminish Wednesday afternoon with light and variable winds
expected overnight. VFR conditions continue throughout the day
on Wednesday as surface high pressure builds overhead.

Cloud cover increases Wednesday afternoon with precipitation
returning to the forecast overnight Wednesday into Thursday. A
wintry mix may bring sub-VFR conditions to the metro terminals
with KCHO and KMRB expected to have rain. Restrictions are
possible through Thursday morning as precipitation moves through
the forecast area. Primary precipitation type will likely be
rain with temperatures right at or above freezing, although a
rain/snow can`t be ruled out. Conditions improve Thursday night.

Friday will see plenty of cloud cover along with a wintry mix,
particularly north of I-66/U.S. 50. Lengthy restrictions are
looking likely as wintry precipitation falls amidst the low
ceilings. Some ceiling restrictions could continue into portions
of Saturday with moisture overrunning a boundary over the
Carolinas. By Sunday, rain overspreads the region ahead of a
strong cold front. Thus, expect additional periods of sub-VFR
conditions across the terminals.

&&

.MARINE...
Winds remain below SCA criteria through the overnight before
increasing Wednesday morning in the wake of a cold front.
Another SCA goes into effect Wednesday morning as winds across
the waters gust up to 25 knots. Winds diminish Wednesday
afternoon as high pressure builds overhead.

As low pressure impacts the waters on Thursday, winds near SCA
criteria in the southern portions of the waters. Additional
SCAs are possible.

While a wintry mix may impact portions of the waters on Friday into
Friday night, wind fields should stay below advisory criteria. Any
threat for hazardous marine conditions should wait until Sunday with
the approach of a strong cold front.
