.SYNOPSIS...
A cold front will push to our south this afternoon with high
pressure building in overhead tonight into Sunday. On Monday, high
pressure will be pushed offshore as the next low pressure system
approaches the area by midweek. A warm front will lift through the
area on Tuesday with a strong cold front set to move through the
area on Wednesday. High pressure returns for Thursday and Friday.


.NEAR TERM /THROUGH TONIGHT/...
Mid-Morning Update: Regional mosaic radar loop as of 10:00AM
shows precipitation moving into the forecast area from the west.
Snowfall can be seen on traffic cameras in Garrett County with
snow beginning to stick on grassy surfaces. 12Z hi-res model
guidance this morning continued to show some uncertainty in
snowfall totals today. Both the HRRR and NAM showing decreased
snow amounts, but the RAP and Namnest showed a shift northward
bringing more snow the northern Garrett County. Overall, we are
expecting 1 to 2 inches of snow at higher elevations with a
worst case scenario of 2 to 4 inches along the highest ridges
(i.e western Highland and Pendleton Counties as well as up
around Wintergreen/Afton Mountain along the Blue Ridge). For
now, will continue to hold off on any headlines given the
uncertainty with a mention in the HWO.

Previous Discussion Follows: Shortwave low pressure continues
to lift north and east through eastern PA late this morning
with its associated cold front sagging southward into central
VA. This low pressure system will ride along the slow moving
cold front into southwest and central VA this morning and into
the afternoon hours. Accumulating snow is possible along the
Alleghenies, portions of the Potomac Highlands, and central Blue
Ridge/Shenandoah Valley. Some uncertainty remains in regards to
overall accumulation due largely in part to the bulk of the
snow falling within the max insolation period this afternoon
into early evening 18-00z/1-7pm. Either way, if you are
traveling in these areas plan for slick road conditions as
temperatures look to fall throughout the day and into tonight as
additional CAA pours in. Elsewhere, dry conditions will prevail
with a slight chance of rain mainly in areas south of I-
66/US-48 (Corridor H).

Dry conditions and clearing skies are expected later this afternoon
across the PA/MD border sinking south toward I-66/US-50 this
evening as high pressure builds in. Areas further south will
likely hold onto the clouds a bit longer with clearing
overnight. With low pressure and the associated front passing to
the south and high pressure building in from the north and west,
expect a tightened pressure gradient across the region. This
will result in gusty north to northwesterly winds at 15 to 20
mph yielding wind chill values in the 20s over the mountains and
30s elsewhere across the region. High temperatures will also be
much cooler compared to the last few days with highs in the mid
to upper 40s (30s over the Alleghenies).

Skies clear out tonight with diminishing winds giving us a good
radiational cooling setup. This will allow low temperatures to drop
into the 20s for most of the area.


.SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/...
Dry conditions and more sunshine is expected with high pressure
Sunday. High temperatures will climb into the upper 40s and low to
mid 50s. High pressure slides offshore Sunday evening into Sunday
night allowing for return flow back into the region. Some upslope
precip is possible west of the Allegheny Front late Sunday night
into Monday morning as a result. Low temperatures Sunday night will
fall into the mid to upper 30s with increasing south to
southwesterly flow.

South/southwesterly return flow continues around the departing high
pressure off the Mid-Atlantic coast Monday into Monday night.
Additional showers remain possible west of the Allegheny Front with
most locations remaining dry as moisture steadily builds into the
region. Clouds will begin to increase from the west ahead of an
approaching frontal system late Monday and into Tuesday as the
weather pattern turns active for the extended period. High
temperatures Monday with increased south/southwesterly flow will
push into the upper 50s and low to mid 60s. Overnight lows Monday
night will fall Into the mid to upper 40s.


.LONG TERM /TUESDAY THROUGH FRIDAY/...
A strengthening southerly flow ahead of a rapidly deepening
area of low pressure tracking from the Midwest through the
upper Great Lks and into northern Ontario will usher in milder
temperatures during the middle portion of next week and bring
the threat of showers. There is also a non-zero chance of
t-storms Wed, but the risk is not great. It will turn
breezy/windy Tue night into Wed in the pre-frontal air mass
with winds gusting up to 40 mph (sub-advisory criteria), but at
higher elevations, the winds could gust up to 50 mph specially
over the most favored slopes of the Blue Ridge Mountains (i.e.
Wintergreen). The front clears the area Wed evening with high
pressure building over the region during the second half of the
week.

Another system may bring more precipitation toward the end of
next week, which may begin as mixed precip across the higher
elevations with rain elsewhere.
