Area Forecast Discussion
National Weather Service Blacksburg VA
127 PM EDT Fri Apr 7 2017

.SYNOPSIS...
Strong low pressure to the north should slide east across New
England today before exiting the area overnight. High pressure
will build in from the west late tonight and remain over the
region for most of the weekend. The high shifts offshore by
Monday resulting in much warmer temperatures for early next
week.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 127 PM EDT Friday...Changes made with the midday update
were to cancel the Winter Weather Advisory for Ashe, Watauga and
Grayson Counties. However, the Winter Weather Advisory was
extended a bit further in time until 4 pm for western Greenbrier
County. Snow showers continue to develop further into central
West Virginia and at least some of those snow showers probably
will make it into the Advisory area. An additional inch or two
may be possible in the most persistent snow showers, on top of
what had already fallen (per recent PNS, around 3 inches has
fallen in towns such as Quinwood and Rupert). We should see a
decrease in areal coverage in snow showers by mid-afternoon,
with a decision regarding the status of that Advisory
forthcoming later pending trends.

Also monitoring wind gusts and the associated headlines for
those. At present, while certainly quite breezy in the Advisory
area, winds have run at worst on the lower end of Advisory
levels in the Advisory area. Still continue to see rather strong
gusts along the Blue Ridge into Roanoke and those should
continue. Continuing to monitor...

Previous near-term discussion issued at 245 AM follows...

Not a lot of change with the deep upper trough to cross the region
today with a final embedded shortwave pivoting through this
afternoon. This will make for continued rather chilly/blustery
conditions with more clouds and lingering snow showers mountains,
and even some strato-cu east given heating under steep lapses
despite strong downslope. Appears best upslope moisture will linger
through early afternoon before significant drying from aloft takes
shape per forecast soundings as the upper support passes to the
east. With ongoing bands already working through the region and
continued support for added shallow convective type banding into the
morning, will keep the winter weather advisory in place. Also expect
some light accumulations elsewhere as well over the higher western
terrain given temps near freezing to start.

Otherwise winds remain the bigger concern today as seeing a surge
through early this morning with the passing stronger 850 mb jet, to
be followed by better mixing during the day, including the passing
shortwave. May still see some gusts into warning levels west within
the advisory area early on, but these speeds appear too brief to
upgrade, while expecting another round of higher speeds to slide
east of the mountains as well. Gradient should start to weaken later
in the day as better drying develops but still enough for gustiness
to linger into the evening espcly mountains. Guidance temps showing
a lot of range pending degree of clouds espcly east where should see
highs mostly in the 50s. Potential for spots over the western zones
to stay in the 30s given the cold pocket overhead so trended toward
colder Mos there with range from 30s/low 40s far west to mid/upper
40s just west of the Blue Ridge.

Upper vortex exits overnight allowing chilly high pressure to the
west to edge east reaching the western slopes of the mountains by
morning. This should allow for clearing skies overnight with perhaps
only the far northwest mountains holding onto low clouds past
midnight. Given the passing upper trough and weakening jet should
see winds slowly diminish overnight but how fast remains in question
in regard to just how cold temps can go. This espcly important
across the east where the growing season has started and despite
light mixing and a rather wide temp/dewpoint spread the threat for
more of a freeze in outlying areas exists. Latest guidance also a
bit colder than previous but coverage of at or below freezing temps
remains iffy as expect mostly sheltered areas away from town to get
that cold. Thus will keep the going freeze watch in place for now
and allow the dayshift another look. Otherwise lows mainly low/mid
30s with a few 20s over the west where the growing season has not
officially started yet.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY/...
As of 430 AM EDT Friday...

Much quieter and warmer weather will evolve through this time
period. The upper low plauging the northeast U.S. will begin to
lift out quickly Saturday. Surface high pressure centered across
the Mid-South will slide east into the southeast U.S. This will
bring a warm, dry west surface flow into the area. 850mb
temperatures will rise quickly from around -6C early Saturday to
around +8C Sunday morning, continuing to surge to +13C by Monday
morning.

The next upstream system to bring any precipitation into the
area will not arrive until at least Tuesday afternoon as upper-
level ridging dominates the eastern U.S. first half of next week
and broad upper troughing dominates the western U.S. Thus...this
entire period will be dry.

As noted above, temperatures will be the main story for this
time frame. Saturday morning will bring freezing temperatures to
most areas west of the Blue Ridge and patchy freezing
temperatures to areas east of the Blue Ridge across the
Piedmont. Winds will remain high enough early Saturday in most
areas to prevent any widespread frost.  By Sunday morning,
despite the increasing 850mb temps, decreasing winds and clear
skies will allow for greater frost potential. Patchy frost has
already been included in the grids across the Piedmont and a
Frost Advisory will most likely need with later forecast
packages.

Temperatures will start out at the beginning of the period 10-15
degrees below normal trending toward slightly above normal
levels by the end of the period.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
As of 430 AM EDT Friday...

A fairly unsettled pattern will evolve during this period as a
baroclinic zone/frontal boundary sags southward into the Mid-
Atlantic region Wednesday, then oscillated back and forth
through the area as a series of weak short waves track from west
to east across the U.S. Instability is marginal, but enough at
times to include thunder, especially Tuesday evening and perhaps
again Wednesday afternoon across the Piedmont.

Temperatures will average above normal through most of the
period, although some cool down is evident late in the week as
the baroclinic boundary sags southward into the southeast
states and 850mb temps, hovering around +14C much of the period,
drop back into the single digits late in the week.

&&

.AVIATION /17Z FRIDAY THROUGH TUESDAY/...
As of 127 PM EDT Friday...

Generally MVFR to VFR ceilings across the TAFs, lowest ceilings
western terminals, with most persistent snow showers at BLF and
at times at LWB reaching MVFR to IFR visibilities. These general
trends should continue through the mid to late afternoon hours.
Northwest winds will remain gusty as well through late afternoon
as well, at times up to 35 kts at Roanoke. Likely areas of
mountain waves in/around the Blue Ridge may produce areas of
localized turbulence for aviation interests around the Blue
Ridge though that period of time as well.

For tonight, we should begin to see significant improvement both
in terms of wind gusts/speeds, and in coverage of snow showers
and associated sub-VFR conditions. By 02z, most TAFs should
trend VFR with northwest winds generally falling to 8-12 kts
before midnight and then further falling to 4-8 kts overnight.

VFR continues through Saturday as high pressure builds in.
Likely to see periodic northwest gusts but not nearly as strong
as today (generally under 20 kts).

Extended Aviation Discussion...

VFR conditions then become the rule through Tuesday. Some
potential for breezy gusty southwest winds ahead of a cold front
Tuesday afternoon. The next chance of rain with sub-VFR
conditions arrives in the central Appalachians on Tuesday night
and Wednesday as a cold front approaches.
