Area Forecast Discussion
National Weather Service Blacksburg VA
122 PM EST Fri Dec 8 2017

.SYNOPSIS...
Low pressure will develop along a frontal boundary over the
Southeast United States today and move northeast and off the
Mid- Atlantic Coast into Saturday. This will produce an initial
mix of rain and snow this afternoon, changing to all snow
tonight into Saturday where the cold air interacts with the
system over parts of the Mid- Atlantic States. Greatest snowfall
accumulations are expected across the southern Piedmont in
Virginia and North Carolina, and the Blue Ridge and southern
foothills in North Carolina.

A stronger front with a shot of colder air and better chances
for mountain snow showers will arrive Saturday night into
Sunday.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 1200 PM Friday...

Digesting new 12z model guidance which have trended higher with
respect to snowfall amounts along the Blue Ridge from Floyd
into the NC Mountains. Headlines will likely need some adjusting
from Floyd-Watauga with respect to amounts that may push
warning criteria. Looking at webcams...very little accumulation
is occurring east of the Blue Ridge where some mix of both
rain/snow is occuring Danville and Vicinity and ground temps
still warm. Will make overall adjustments this afternoon. Only
change to forecast so far is to raise amounts along Blue Ridge
from Floyd to Boone. Reports so far indicate 1 to 3 inches has
occurred within that corridor.

Low pressure is organizing over northern Gulf of Mexico, aided
by a parent mid-level trough evident in water vapor imagery over
southwest Texas. Stream of subtropical moisture continues to
emanate along the northern periphery of a stalled SW-NE oriented
frontal zone over the Deep South.

Nearly all 00z guidance trended much wetter, nearly by a factor
of 2 compared to 12/18z solutions from Thursday. Key in that
wetter trend is the faster digging northern-stream trough making
headway in the Canadian Prairies, offering the potential for at
least some (though not fully complete) phasing of this northern
stream with the aforementioned southern stream trough expected
to be in the Tennessee Valley later tonight. Though the Advisory
takes effect at noon, the most impactful period based on
current guidance indications is overnight tonight into early
Saturday.

There's still a considerable deal of uncertainty on snow
accumulations, involving multiple angles: (1) likely warm
pavement temperatures limiting impactful accumulations until
better, frontogenetically-enhanced precip rates can force more
snow (2) when snow actually ends (3) Snow to liquid ratios (SLR)
values should be initially low due to rain/snow mix falling in
marginally supportive temperatures and isothermal thermal
structure aloft, before increasing to approximate 10:1 values
overnight and (4) the westward extent of the QPF shield, given
likelihood of dry air potentially eroding significant snow
accumulations from the Blue Ridge westward than guidance
consensus QPF presently indicates.

So with that stated, for today we'll be looking at precipitation
moving northward into VA from the Carolinas with precipitation
type initially a cold rain across the piedmont. Wet-bulb
effects should produce a mix of rain and wet snow during the
afternoon across the piedmont and all snow the closer you get to
the Blue Ridge. As mentioned, I'm highly dubious that wet snow
will accumulate on anything other than grassy, elevated or
shaded surfaces through the daylight hours over the Piedmont
where ground temperatures too warm to permit accumulations on
pavement/asphalt. It will be a different story along the Parkway
and elevations above 1500 feet where both ground and air
temperatures are colder.

As the afternoon and evening progresses, a northwestward
expansion of the precipitation shield is anticipated, while the
strongest 850-700 mb frontogenesis begins to pivot northwestward
from the central Piedmont of NC. Precipitation rates should
begin then to increase, and rates should be sufficient enough
to overcome warm pavement and allow for greasy accumulations on
pavement beginning tonight in the Advisory area. In the Advisory
area, several inches of snow may accumulate, roughly from one
to three inches in the Piedmont/foothills and 3-6" along the
southern Blue Ridge in NC and into Grayson, Carroll, Floyd,and
Patrick Counties...although these numbers may need to be
adjusted upward pending model trends. Much of this will fall
tonight into Saturday (into the Short- Term period). From an
impacts perspective, it appears that the evening period would be
the beginning of the most adverse of impact with the likelihood
of a wet, greasy snow as temperatures fall after sunset.

&&

.SHORT TERM /SATURDAY THROUGH MONDAY NIGHT/...
As of 100 PM EST Friday...

As the coastal low pulls away from the region late Saturday, a
cold front will move through the region Saturday evening. This
will bring a reinforcing shot of cold air to the Appalachians
and central mid Atlantic region and set the stage for upslope
snow showers west of the Blue Ridge with a few inches of fluffy
snow expected at the higher elevations. The low level wind field
will also amplify considerably with very blustery conditions
leading to areas of blowing snow and low wind chill values.

Accumulating snow showers will taper off to flurries Sunday
morning but blustery conditions look to continue through the
first part of next week as the wind field remains energized by
numerous short waves zipping through fast upper level flow.

Temperatures will remain well below normal into the first part
of next week. Many locations will see departures of 10 to 15
degrees below seasonal norms.

&&

.LONG TERM /TUESDAY THROUGH THURSDAY/...
As of 100 PM EST Friday...

Amplified upper pattern featuring a western ridge and eastern
trof will persist through next week, though some deamplification
looks to occur toward the end of the week. The main storm track
will keep areas of low pressure moving from the Great Lakes
into New England with trailing cold fronts pushing reinforcing
shots of cold air into the Appalachians with occasional bouts of
snow showers west of the Blue Ridge. The fast moving pattern
will also keep a good amount of energy in the low level wind
field with blustery conditions through the period.

With little change to the cold pattern in place, expect
temperatures to remain well below normal through the upcoming
week.

&&

.AVIATION /19Z FRIDAY THROUGH WEDNESDAY/...
As of 1245 PM EST Friday...

Radar indicates bands of light to locally moderate snow falling
across northern North Carolina and portions of Virginia east of the
Blue Ridge this afternoon, with visibilities within the snow
fluctuating between 1/2SM to 3SM. Further north & west, a sharp
gradient exists between the IFR conditions and VFR conditions, as
moisture associated with the approaching storm system slowly
intrudes into the dry air that was in place across the mid Atlantic.

Snow will move across the area in waves Friday afternoon through
shortly after dawn on Saturday. Most heavily affected airports will
be those east of a HSP to MKJ line, with impacts expected to
decrease further west, areas further removed from the path of the
storm. Greatest hazards will include up and down visibilities in the
heavier bands of snow, as well as ceilings falling below 1kft.
Expect improving conditions after 09/18Z from west to east, as low
pressure begins to drift away from the region and winds shift more
northwesterly.

Medium confidence on aviation elements and timing.

Extended Discussion...

After the passage of low pressure on Saturday, a trailing arctic
cold front is expected to bring another round of snow showers to the
mountains, with potential sub-VFR ceilings and intervals of sub-VFR
visibility, mainly to Bluefield and Lewisburg. Strong northwest
winds are expected behind the front on Saturday night into early
Sunday.

VFR conditions then return Sunday evening through Monday. Next
chance for sub-VFR conditions is with a clipper system Tuesday,
particularly in the western mountains.
