.SYNOPSIS...
High pressure builds over the region tonight into Saturday
morning. An approaching low pressure system and associated
front will bring a chance for precipitation Saturday night into
Sunday, with some wintry mix possible at the onset across
mountain locations. A second low pressure system may bring
additional chances for precipitation Monday night into Tuesday.

.NEAR TERM /THROUGH SATURDAY/...
As of 745 PM EST Friday...

Key Messages:

1) Blustery this afternoon becoming calm tonight with lows in
the teens for most.

2) Moderating temperatures Saturday and dry.

While a few streaky returns continue to show up on radar, it is
unlikely there is any accumulation occurring. At most, you may
be able to enjoy a few flakes illuminated by a streetlight. And
these will continue to become rarer and rarer as high pressure
asserts itself over the area.

The real story are the plummeting temperatures tonight, which
are already well on their way down. Most of the forecast area is
already below freezing, and lows will be in the teens and 20s
areawide.

From the previous discussion...

Measurable snow has all but ended with mainly flurries spilling
across the central Appalachians to as far east as Roanoke.
Tighter pressure gradient this afternoon keeping winds blustery
will begin to weaken tonight as high pressure pushes overhead.
With light/calm winds and less clouds, temps should drop into
the teens to around 20. Not quite record breaking but still
10-15 degrees below normal.

High pressure shifts east Saturday afternoon and return flow
should bring highs up by about 5 to 10 degrees warmer than
today, but still around 10 degrees below normal with 40s for
most, except some lingering 30s in the higher elevations. Clouds
will begin to increase late in the day but should have limited
impact on high temps.

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/...
As of 1235 PM EST Friday...

Key Messages:

1) A low pressure system will bring a light wintry mix in the
mountains on Saturday night before changing to rain by Sunday.

2) Drier air should return during early Monday, but a second low
pressure system will bring another wintry mix on Monday night.

Clouds should increase on Saturday night as a low pressure
system approaches from the west. With surface temperatures
initially below freezing in the mountains, a light wintry mix
appears possible until the southerly flow ahead of the
approaching cold front can boost temperatures above freezing by
Sunday morning. Any ice or snow accumulations will be minor and
mostly concentrated across the Alleghany Highlands of Virginia
and portions of southeast West Virginia. Once the cold front
departs around Sunday evening, some upslope snow showers may
take place from Boone to Lewisburg before the moisture
dissipates by Monday morning.

High pressure will bring a brief reprieve on Monday, but it
should slide northeastward towards the New England states by
Monday night and provide an opportunity for a cold wedge to
develop east of the Blue Ridge. Meanwhile, a second low pressure
system should intensify along the Gulf Coast and head towards
the East Coast. With surface temperatures falling below
freezing, another wintry mix should occur. This time, the
coverage of frozen precipitation may be more widespread, and the
potential exists for higher ice accumulations along and west of
the Blue Ridge.

.LONG TERM /TUESDAY THROUGH FRIDAY/...
As of 1235 PM EST Friday...

Key Messages:

1) Precipitation should change to rain during Tuesday, but
mountain snow showers could follow by Tuesday night.

2) Conditions will turn drier for Wednesday and Thursday before
another low pressure system approaches on Friday.

A wintry mix of precipitation should continue into Tuesday
morning due to a low pressure system tracking northeastward
along the East Coast. Eventually, temperatures will rise above
freezing to change the precipitation over to rain by midday
Tuesday. Once the northwest flow behind the low pressure system
arrives on Tuesday evening, colder air should switch the rain
back to snow showers in the mountains. Meanwhile, moisture
should dissipate across the Piedmont to provide drier conditions
by Tuesday night. The lingering upslope moisture in the
mountains will fade towards early Wednesday morning.

Dry weather should persist for Wednesday and most of Thursday as
high pressure returns. A weak cold front passing to the north
might introduce a slight chance of snow showers across western
Greenbrier County of West Virginia during Thursday afternoon,
but this moisture should diminish by Thursday night. Meanwhile,
another low pressure system could develop along the Gulf Coast
and spread moisture northeastward towards the Appalachian
Mountains on Friday. Early indications suggest that this system
may bring yet another opportunity for a light wintry mix in the
mountains during Friday morning before changing to rain by
midday Friday.

.AVIATION /01Z SATURDAY THROUGH WEDNESDAY/...
As of 800 PM EST Friday...

this period. Clouds will be sparse or non-existent. A few
flurries continue to fly, but will be less and less frequent
throughout the night. Temperatures are bitterly cold. Winds will
be light from the west-northwest, but will become more easterly
by Saturday afternoon, still light though.


.EXTENDED AVIATION OUTLOOK...

Unsettled weather for aviation in this region late Sat night
into Sunday with wintry mix/ice likely Sunday morning, changing
to rain, then a reprieve Monday before another wintry to rain
system arrives Monday night into Tuesday.
