Area Forecast Discussion
National Weather Service Blacksburg VA
230 PM EDT Sun Apr 14 2019

.SYNOPSIS...
A strong cold front will bring rain and an enhanced risk for
severe thunderstorms to the region this afternoon and tonight.
Following the front, high pressure will settle over the region
for the first half of the week.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 225 PM EDT Sunday...

Tornado Watch #62 is in effect for counties along and east of
the Blue Ridge until 8 PM.

As of 100 PM EDT Sunday...

Showers across the mountains keeping thunderstorms threat low
through early this afternoon. By mid afternoon, heating will
increase instabilities for the cold front to produce strong to
severe storms into the evening.

Some clear skies east of the Blue Ridge increasing
instabilities through the afternoon. Bands of strong to severe
storms are tracking over the foothills. By mid afternoon, these
storms will bring the threat for severe weather to the
piedmont.

SPC chance for a watch is currently at 60 percent.

As of 345 AM EDT Sunday...

Zero chance of quiet weather this period. Still an enhanced risk of
severe thunderstorms this afternoon and tonight in association with
a strong cold front. In addition, a strong southerly low level jet
will mix down gusty winds outside of any thunderstorms across the
higher elevations of southern WV to the NC mountains, so a wind
advisory has been posted to account for this, for this
afternoon/evening.

Early this morning, 996 mb low pressure was located near Memphis,
with a warm front stretching northeast into WV, then southeast
across southern VA. This warm front should lift northward this
morning, with our entire area in the warm sector today. A few
showers showing up across the southern CWA in as moisture transport
increases out of the south. Following close to the high-res models
through today shows best chance of showers along the southern Blue
Ridge and adjacent areas this morning. Cloud cover will be
problematic at first in terms of convection, but strong dynamics
this afternoon with a screaming 55-65kt low level jet working across
should overcome any marginal CAPE to develop thunderstorms.

Severe thunderstorm risk still appears two-fold, with pre frontal
development associated with the low level jet and convergence moving
out of the southern Appalachians this morning into the High Country
of NC to the New River Valley by early afternoon, then heading east
to the piedmont by mid-late afternoon. Along and east of the Blue
Ridge may be an area to watch this afternoon for possible tornadoes,
as high-res models showing best 0-1km SRH of 300-400. Meanwhile,
LCLs stay under 1000m so folks east of the Blue Ridge should be
alert to rapidly changing conditions.

The main front is set to bring a line of storms into the mountains
by 6-8pm, then speeding east and out of the forecast area after
midnight. This will bring the damaging wind threat to the mountains.
High-res models and to some extent the synoptic models have sunshine
developing in the west this afternoon behind the first wave of
convection. This seems reasonable given mesoscale sinking and
downslope effects of a southerly wind. This should get the airmass
unstable once again but models do show by the time this line heads
over into the foothills/piedmont it looks to weaken per worked over
airmass from earlier convections. Nonetheless, all areas today will
be under the umbrella of a severe thunderstorm threat.

As far as heavy rain/flooding potential, it still exists, and will
have to watch how much rain falls with pre-frontal convection. Storm
motion will be fast, as much as 40 to 60 mph from the southwest to
the northeast, while the line moves eastward. The transient nature
of this should limit flooding, but with PWATS approaching 2 inches
this afternoon ahead of the front any training may cause problems,
and convective allowing models show the greatest threat of flooding
based on reflectivity and QPF forecasts to be over the NC mountains,
to the foothills of VA. Still confidence is not high enough to have
a flash flood watch out.

Once we get through this severe threat colder air will move into the
mountains, with upslope showers lingering in the mountains, changing
to snowflakes in the highest ridges. West winds will be kicking in
as well as pressure rises in 6 hours ramp up to 5 to 9 mb. Will
likely need wind headlines post-frontal for late tonight into the
next period, but after collaboration with neighboring offices, we
decided to hold off and concentrate more on the severe threat.

Skies east tonight should rapidly clear after midnight, while
upslope clouds keep the mountains mostly cloud to overcast.

Highs today will be tempered some due to cloud cover, but warm
advection should send temps to the 70s most place, potentially
reaching 80 out east if any period of sunshine is realized.

Temps tonight will be ranging from the mid to upper 30s across the
higher elevations, to lower to mid 40s elsewhere west of the Blue
Ridge, to upper 40s to mid 50s east.

High confidence forecast for severe thunderstorm and wind threat,
medium on temps and cloud cover, and medium on flood threat.

&&

.SHORT TERM /MONDAY THROUGH WEDNESDAY NIGHT/...
As of 300 AM EDT Sunday...

The low level wind flow will amplify as colder air continues to push in
behind the front on Monday. This will combine with good downward
momentum transfer to make for strong gusty winds especially along and
west of the Blue Ridge with gusts of 40 MPH to 50 MPH possible on the
hilltops. The energetic northwest flow will also generate a good amount
of upslope clouds and showers west of the Ridge with some wet snow for
the higher elevations, but accumulations do not appear likely given
April insolation. Building high pressure will eventually slacken winds
and lingering precipitation looks to be gone by Monday night, and fair
weather is on tap for Tuesday and Wednesday.

Temperatures will be well below normal behind the front on Monday with
highs in the low to mid 60s east of the Blue Ridge and nearly steady in
the mid 40s/lower 50s to the west. Lows monday night will also be quite
chilly with readings in the upper 30s/around 40 east to low/mid 30s
west. However temperatures will rebound nicely with readings well above
normal through the middle of the week.

&&

.LONG TERM /THURSDAY THROUGH SATURDAY/...
As of 230 PM EDT Saturday...

During this portion of the forecast, we will encounter a
weather pattern similar to what is playing out across the region
today into tomorrow.

An upper level trough is expected to deepen over the Rockies
and head eastward into the Central Plains states where it
develop into a strong upper level low during the Thursday time
frame. A strong southerly fetch of moisture will race north from
the Gulf of Mexico in advance of this system and progress into
our region. The upper low's associated cold front is expected to
cross our area Thursday night into Friday. Model vary on the
timing, but currently this is the general span of time offered
for this occurrence. Some guidance track an additional shortwave
trough northward along this front on Friday, slowing its
departure, and thus keeping the potential for active weather
into Friday night. The parent upper low and its associated
trough axis is expected to cross the area Saturday or Saturday
night.

What the above scenario means for our region will be
temperatures on the mild side in advance of this approaching
upper low/trough. Plenty of moisture and lift to have showers
probable Thursday through Friday, and perhaps even Friday night.
Thunderstorms, some potentially on the strong side thanks to
notable low level shear and marginal SBCAPE, will be possible
Friday afternoon and evening.

Cooler weather and gusty northwest winds are expected behind
the system, but this detail currently will fall outside the
extent of our seven-day forecast, more within the Saturday night
into Sunday time frame.

Temperatures during through Friday are expected to average 10
to 15 degrees above normal. On Saturday, readings will be closer
to 5 to 10 degrees above normal.

Confidence in this portion of the forecast is moderate. The
biggest question is how any change in timing of the upper low
and its associated surface features will impact the sensible
weather.

&&

.AVIATION /19Z SUNDAY THROUGH FRIDAY/...
As of 120 PM EDT Sunday...

Unsettled weather today will lead to poor flying weather in the
region. Some showers out there this morning with cigs and vsbys
around MVFR to at times IFR, and even LIFR near mountains and
Roanoke.

Looking at impactful weather today across the region as a
strong front and upper system move from the MS Valley to the
southeast U.S. There looks to be two rounds for our area, one
ahead of the front during the afternoon in the 18-00z time
frame from west to east, then the front a line of convection
itself moving west to east from 00z-06z. Expect gusty winds from
the south to the southwest with storms with sub-MVFR
conditions. Expect mainly VFR outside of it. After the front
tonight, looking for improving conditions in terms of cigs/vsbys
east of the mountains with clearing skies. MVFR cigs will
linger in the mountains til Monday morning.

Confidence is average for the ceilings and above average for
the thunderstorms and wind. Confidence is below average for fog
and visibilities.

EXTENDED AVIATION DISCUSSION...

Wind starts to diminish into Monday night as high pressure
builds in. VFR expected through Thursday.
