High pressure will build overhead through tonight before moving
offshore Friday through Friday night. A cold front will pass
through the area Saturday, then high pressure will return for
Sunday into Monday. Low pressure and its associated cold front
may impact the area during the middle portion of next week.

A Wind Advisory remains in effect for the Allegheny Highlands
through early this morning. Wind along the Allegheny Front will
gust to around 50 mph, but there has been a downsloping wind
that made it a little east of the front around Cumberland as
well. Winds should gradually diminish this morning as the
gradient slowly subsides.

High pressure will continue to build toward the area behind a
cold front through this afternoon. Gusty northwest winds are
expected through midday ahead of the building high, before
gradually diminishing later this afternoon. The northwest winds
along with chilly conditions will make it feel blustery and
cold today, despite sunshine. Highs will range from the 20s and
lower 30s in the mountains to the 40s for most other locations,
with near 50 in central Virginia.

High pressure will settle overhead tonight, causing light winds.
There will be some cirrus clouds, but the cloud deck should be
thin so radiational cooling is expected tonight. Min temps will
range from the teens and lower 20s in the colder valleys and
rural areas, to the mid and upper 20s for most other locations
with near 30 in downtown Washington and Baltimore.

High pressure will move offshore Friday and a southerly flow
will develop. The southerly flow with sunshine will allow for a
more seasonable afternoon with highs in the upper 40s to mid 50s
for most areas (lower to middle 40s in the mountains).

A cold front along with its associated upper-level disturbance
will move through the Great Lakes into the Ohio Valley Friday
night. A southerly flow will strengthen ahead of this system,
allowing for Friday night to be milder with lows in the upper
30s to mid 40s for most areas. However, moisture advection
along with divergence aloft in the upper-level jet means that
clouds will increase and chances for precipitation will increase
overnight. The best chance for rain will be west of Interstate
95 to the Allegheny Highlands toward morning.

Rain will overspread the rest of the area for a period Saturday
as the cold front moves east. There will likely be a break in
the precipitation later Saturday morning into Saturday
afternoon, but a few showers are possible until the cold front
passes through later Saturday afternoon into Saturday evening
from northwest to southeast. Breezy conditions are expected
ahead of the cold front, with the strongest winds most likely in
the mountains. Frequent gusts around 25 to 35 mph are most
likely in the valleys with 40 to 45 mph most likely in the
mountains. A few gusts around 50 mph are possible along the
highest ridge tops and perhaps just east of the Allegheny Front
(downsloping flow), but confidence is low at this time.

High pressure will build overhead behind the cold front Saturday
night bringing a return of dry and chilly conditions.

Strong ridging will be building over Greenland and Alaska
heading into next week. In between, troughing dipping out of
Canada will be battling with ridging over the Gulf of Mexico.

The result locally will be a period of unsettled weather as a
front system and areas of low pressure waver about the area.
Most of the area should see any precipitation fall as rain, but
there may be just enough cold air at times near the Mason-
Dixon line and near/west of the Blue Ridge Mountains for a bit
of a wintry mix (mainly Monday-Tuesday).

Temperatures are expected to trend warmer the first couple days
of next week before trending cooler Wednesday into Thursday.
