Area Forecast Discussion
National Weather Service Blacksburg VA
356 PM EDT Sun Jun 4 2017

.SYNOPSIS...
A warm front will lift northeastward across the region into
Monday, shower and thunderstorm coverage increasing across
the Mid Atlantic Region. Unsettled weather will then persist
until a cold front sweeps through the region late Monday night
or early Tuesday. Passage of Tuesday's front will be followed by
a cool late season cutoff low which will settle over the
northern Mid-Atlantic for mid-week, temperatures retreating to
the cooler side of normal.

&&

.NEAR TERM /THROUGH MONDAY/...
As of 400 PM EDT Sunday...

Dry high pressure will move east overnight. Behind this high
pressure is southerly flow which will increase moisture from the
Atlantic into the region. Another contributor of moisture is a
closed low that will wobble over the southern plains through Monday.
This low will bring Gulf moisture into the region. PWATS this
morning were 0.59 of an inch across the mountains and 0.84 of an
inch over the piedmont. Models are bringing PWATS of 1.50-2.00
inches into the area which is 150-200% above normal. This may seem
aggressive considering we were so dry this morning, but Nashville's
morning sounding has PWATS of 1.72 inches and Atlanta was 1.64
inches. This air mass is heading our way.

The southern plains upper low will also send short waves over the
region. Each wave will help add moisture to the area. A northern
stream low over the Great Lakes will send a weak cold front towards
the region tonight and Monday. A surface wave is expected to form
along this front tonight and track east in zonal flow. Most models
are in agreement with tracking this surface low over the forecast
area. However, they differ some on where the axis of heavy rain will
occur. The GFS has the axis over the Greenbrier Valley to the
Southern Shenadoah Valley. The NAM is slightly south from Bluefield
WV to Lynchburg VA. The ECM with its course resolution, looks like a
combination of the GFS and NAM. Models, especially the GFS, may be
overdone on rainfall amounts due to convective feedback. Within the
axis of heavy rain, north of HWY 460, up to two inch of rain
possible and around an inch south into early Monday afternoon. With
the lack of rain the past several days, these amounts will not cause
any flood concerns as long as repeated strong storms do not train
over the same area over and over again through the night. The
surface low will track towards DC by early afternoon with rain
becoming light or ending all together.

With a humid air mass entering the area tonight, temperatures will
remain on the muggy side with lows only falling into the 60s. If the
rain can clear out by early afternoon, temperatures maybe able to
warm into the upper 70s to lower 80s.

&&

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/...
As of 315 PM EDT Sunday...

Deepening Great Lakes upper low will sag southward into the
Mid-Atlantic Region through mid-week, stalling near the PA/MD
border B4 finally lifting back north toward the end of the week.

With the upper low over the region, anticipate cooler than
normal temperatures with highs confined to the 60s in the
mountains and 70s piedmont. Cold air aloft will also drive
diurnal showers...this pattern favoring very little precip at
night but enough instability during the day for widely scattered
afternoon and evening showers. The mountains and northern areas
will likely tend to be the more favored for showers per per
orographic lift and proximity to the upper low, however due to
the warm June sun, enough instability should be generated for
threat to extend into the VA/NC Piedmont also...in addition to
steep enough lapse rates for an isolated rumble of thunder.
Overall QPF should not be much...mainly a tenth of an inch or
less, with most folks remaining dry.

Coolest of the airmass is forecast to pass overhead Wednesday
night into Thursday morning, 85h temps approaching 8 deg C. This
will promote surface temperatures of 5 to 10 degrees below
normal.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
As of 330 PM EDT Sunday...

The upper level Low will slowly lift northward out of the area
by Friday, resulting in decreasing rain chances and a slow
warming trend. A short wave will move through the Great Lakes in
the wake of the upper Low Saturday as it continues to lift
north and away from the area. This short wave feature may bring
some showers to the area, mainly during the peak heating part
of the day Saturday late afternoon. Overall, heights are rising
across the eastern U.S. for the weekend resulting in a less
active and much warmer weather pattern. Both the GFS and ECMWF
have a 590 dm upper level ridge of High pressure over the area
by Monday of next week. This suggests high temperatures will
flip to the warm side of normal with highs into the 80s and 90s
as we transition into Mid June.

&&

.AVIATION /19Z SUNDAY THROUGH FRIDAY/...
As of 135 PM EDT Sunday...

VFR conditions will continue at the TAF sites through this
evening. Low level moisture will be on the increase on the
heels of southwest winds in advance of a low pressure across
the southern plains. MVFR cigs will begin to develop first
over the NC High Country with thunderstorms this afternoon and
into the evening. Lower ceilings and rain will spread into the
area from the southwest to northeast after 06Z, with most TAF
sites seeing IFR cigs/vsbys in place by daybreak Mon, although
it may take until just after daybreak Mon for this to occur at
KLYH. Winds will be mainly southwest 5-10kts through the period.

Expect widespread rain through the day Monday tapering off from
the northwest to southeast during the evening. Expect IFR or
worse cigs/vsbys through much of the morning, potentially
improving to IFR/MVFR later in the day.

Extended Aviation Discussion...

Monday night into Tuesday the front will be east of the area and
northwest winds will be on the increase on the backside of the
system. However, an upper low will persist over the region
through mid week keeping rather unsettled conditions in place,
especially across the mountains with variable MVFR clouds and
patchy rain showers. Conditions should begin to improve overall
after Wednesday with the upper low shifting east and south of
the area.

&&

.HYDROLOGY...
As of 500 AM EDT Sunday...

With no substantial rainfall over the area in just a little over a
week now, 1-hr, 3-hr, and 6-hr flash flood guidance numbers have
increased notably as compared to where they were at the point of our
last substantial rainfall.  Values are lowest in the north where 1-
hr numbers are in the 1.25 to 1.50 inch range with 6-hr numbers
around 2.00 to 2.25 inches. Across the south, 1-hr values are closer
to 2.00 to 2.50 inches with 6-hr numbers in the 3.00 to 4.00 inch
range. Forecast average rainfall during the bulk of the upcoming
event will range from 1.0 inch to 1.50 inches, with most of
this falling over a 12-hr period from roughly midnight to noon
on Monday. Will need to continue to monitor the progression of
how the system is developing, but at this point, confidence in
flooding is not high enough to warrant a watch. Will continue to
highlight the concern in the Hazardous Weather Outlook and the
experimental graphical HWO.
