Area forecast discussion, Jan 4, 9:21 PM EST, 6 hours 12 minutes before
Area Forecast Discussion
National Weather Service Blacksburg VA
921 PM EST Thu Jan 4 2018
.SYNOPSIS...
Strong Arctic high pressure will gradually build in from the
northwest tonight through Saturday resulting in continued
bitterly cold temperatures and low wind chills. The center of
the high should pass overhead by the end of the weekend ahead of
the next complex area of low pressure that arrives for early
next week.
&&
.NEAR TERM /THROUGH FRIDAY/...
As of 915 PM EST Thursday...
No changes were made in time or location to the current wind
chill advisories/warnings. Over the past 1-2 hours, an uptick in
wind gusts has been observed as another vort lobe swings through
our area as seen on GOES-east. The HRRR low level wind forecast
has a good handle on this trend and indicates low level winds
peak around 06Z, and it is not until after 10-12Z before wind
begin to diminish. Pushed up wind gusts a few MPH in the
forecast update and lowered temps a degree or so.
Bands of light snow continue to bleed into the foothills of VA,
and expanded low POPs east to cover these areas including
Carroll, Floyd and Franklin counties. High-res model soundings
show depth of shallow moisture layer not diminishing until
Friday morning. While this will fall for several hours, the
very high snow-liquid ratio will keep accumulations light.
Expect both snow showers and winds to decrease some Friday
morning as the low level flow briefly turns more westerly and
forecast soundings show the depth of moisture decreasing from
above as the inversion lowers. However still enough to keep some
flurries/snow showers going just from the cold advection so
keeping in clouds/pops west and mainly clear east.
Better subsidence along with even drier air will work in during
Friday with lingering snow showers likely early across the west
before shrinking in coverage from south to north by afternoon.
Winds should still be gusty but not quite as strong as today
with the pressure gradient slowly weakening as low pressure
pulls farther away. However still cold enough for advisory level
wind chills to linger until midday and perhaps all day across
the mountains espcly where clouds linger. Otherwise despite more
insolation, little change in 85h temps suggests highs mostly
teens west to around 20 Blue Ridge, and mid/upper 20s east
where slight downslope warming should help a bit given the dry
air.
&&
.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT/...
As of 215 PM EST Thursday...
Very cold with gusty winds and dangerous wind chills into the weekend,
some moderation Sunday.
Arctic high pressure will continue building down from the upper midwest
and will bring the core of the cold air through the region Friday night
and Saturday. Winds will also remain blustery and create very low wind
chill values through Saturday morning. Lingering upslope snow
showers/flurries will also continue west of the Blue Ridge with some
light additional accumulation possible mainly at the higher elevations
around western Greenbrier county WV.
As the center of the high drifts over the region Saturday night
conditions, winds will slacken and there should be a window of time
with good conditions for radiational cooling before mid/high clouds
move in and winds shift to the southeast late. If clouds are slower to
move in and a strong enough surface inversion can become established to
keep winds at bay, temperatures could really plummet to some
impressively cold lows by daybreak Sunday.
As the high moves off to our east on Sunday and winds become southerly
we will finally start to break out of the cold. The persistent upper
low that has been keeping the cold air locked in over the eastern US
will give way to a much more progressive and warmer pattern. A very
brisk southwesterly low level jet will start advecting warmer air in
the region, and good isentropic lift will develop Sunday night ahead of
a frontal system approaching from the west as the region gets split by
low pressure moving by well to our north and south. Low level moisture
return will be slow so it looks like the better chances for
precipitation will be holding off until mainly after daybreak Monday.
&&
.LONG TERM /MONDAY THROUGH THURSDAY/...
As of 215 PM EST Thursday...
Definitely trending to a warmer synoptic pattern next week as
progressive low amplitude flow evolves to a deepening trof in the west
with sympathetic ridging in the east. Expect temperatures to be at or
slightly above normal by midweek.
Cold front will be moving through the region Monday/Monday night with a
good chance of precipitation. With all of the warming aloft and cold
air at the surface Bufkit soundings have a distinct look of freezing
rain, especially given the very cold ground temperatures coming off our
spell of cold weather. The combination of QPF and cold temperatures
looks favorable for a decent glaze of black ice Monday before surfaces
go above freezing. Will continue to assess potential impacts with later
model runs.
As this system pulls away on Tuesday we can expect some lingering
upslope rain/snow showers west of the Blue Ridge, followed by generally
dry weather through midweek.
&&
.AVIATION /02Z FRIDAY THROUGH TUESDAY/...
As of 635 PM EST Thursday...
A strong storm system off the New England coast this evening
will continue to move away from our area, but strong northwest
winds in the wake of the system will keep persistent MVFR cigs
to mountain TAF sites including KBCB, KBLF, and KLWB through at
least Friday morning. Ceiling may drop to IFR levels at KLWB and
KBLF tonight with localized snow showers.
East of the Blue Ridge (KROA/KLYH/KDAN), VFR conditions should
continue with ceilings at ROA remaining at VFR levels.
Very strong northwest winds will continue to create issues with
flying through Friday morning with gusts to 40+ knots possible
over the mountains, and 30+ knots possible across the Piedmont
locations.
Of note...the observation from KDAN is unavailable due to
problems with power from early this morning. Will continue to
provide a forecast TAF without a NIL AMD since VFR and winds
remain the only issue at this point.
Extended Discussion...
A prolonged period of strong northwesterly winds with MVFR to
flight restrictions due to upsloping clouds and snow showers
will persist west of the Blue Ridge into Friday night/early
Saturday East of the Blue Ridge, gusty downsloping winds will
maintain VFR flight conditions across the Piedmont.
Arrival of the surface high pressure system on/by Sunday will
bring diminishing winds, a return to widespread VFR weather
(even in the mountains), and slowly moderating temperatures.
Arrival of a fast moving low pressure system may result in
another round of sub-VFR flight restrictions mainly west of the
Blue Ridge on Sunday night - spreading east across the Piedmont
on Monday. Widespread MVFR to IFR restrictions with a wintry mix
of precipitation gradually transitioning over to rain is
expected as the system moves northeast through the region on
Monday. Return to VFR across the region should occur on Tuesday
with perhaps only some lingering MVFR cigs across the mountains
early on.
&&
.FIRE WEATHER...
Antecedent conditions are dry. In spite of the cold, the
dryness of the current Arctic airmass and lack of meaningful
precipitation the last 30-60 days is beginning to set the stage
for potential fire concerns. Sun angle is low so the active burn
window is small, however with little or no moisture recovery at
night conditions are becoming favorable to sustain fire starts
if they occur. Ignition sources for this time of year given the
cold weather would most likely come from hot ashes being dumped
out by folks using wood stoves.
&&
.CLIMATE...
A continued series of Arctic air masses is expected during the
next 3 or 4 days, likely threatening record low maximum
temperatures and perhaps even record low minimum temperatures.
Here are the records for the next several days.
