Area Forecast Discussion
National Weather Service Blacksburg VA
301 PM EDT Tue May 15 2018

.SYNOPSIS...
A stationary front will remain just over the Mid Atlantic region
and Ohio Valley for the rest of the week. Tropical moisture
will intersect this boundary resulting in daily showers and
thunderstorms through at least Friday. Temperatures will stay
above normal.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
As of 245 PM EDT Tuesday...

Thunderstorms have initiated due to orographic forcing in a
moist unstable environment. Expect terrain and outflow
interaction to be dominant factors affecting movement and
propagation of storms. Expect locally heavy rain from any storms
and a marginal threat for severe weather especially from I-64
northward. There looks to be enough forcing from weak short wave
energy in the juicy airmass to keep showers stewing around
overnight especially from the mountains of NC up through the
Shenadoah valley.

Approach of low pressure in tropical airmass will keep a good
chance for showers and thunderstorms across the region again
tomorrow, though greater coverage and increased cloud cover
will limit instability a bit and significant shear will remain
absent.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY NIGHT/...
As of 315 AM EDT Tuesday...

This portion of the forecast period is shaping up to one
characterized by frequent, and potentially heavy, rainfall. The
baroclinic zone that is currently north of our region will gradually
move southward and be positioned over our region. Concurrent to this
event, we expect a very strong and moist flow off the eastern
portion of the Gulf of Mexico. This flow will maintain itself
through Friday on the east side of an upper low that is progged to
move north from the panhandle of Florida to central Kentucky. This
persistent flow crossing the baroclinic zone almost on an orthogonal
angle will help to maximize rainfall across the area. We will need to
monitor on a daily basis how much rain has fallen in comparison with
the various flash flood guidance to assess any need for flash flood
watches and/or warnings.

Temperatures during this portion of the forecast will average about
five degrees above normal.

&&

.LONG TERM /SATURDAY THROUGH MONDAY/...
As of 309 PM EDT Monday...

The weekend will start with a upper level low positioned across
IL/IN/OH.  The generous southerly stream of moisture that was over
the area Thursday and Friday, will continue to hold fast for
Saturday as well. Look for scattered to likely coverage showers and
storms across the area again, with the potential again for some
locally heavy rain.

The activity will wane Saturday night with the loss of daytime
heating, plus the best upper level dynamics will weaken as the upper
low opens up, and gets ejected northeast in advance of an
approaching cold front.

On Sunday, the approaching cold front will still be upstream of the
region, but a continuation of a moisture rich low level profile,
combined with daytime and differential heating will allow for
scattered shower and some thunderstorm development.

The cold front is expected cross the area on Monday, allowing for a
return of greater coverage of showers and storms across the region.
Chances decrease only slightly on Tuesday thanks to the front
stalling just to our south, and then starting to make headway north
again by the late afternoon.

Temperatures during this portion of the forecast will average five
to ten degrees above normal.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
As of 245 PM EDT Tuesday...

Thunderstorms will be affecting TAF sites early his period,
especially along and west of the Blue Ridge. Terrain and outflow
will play a big role in storm formation and make specific timing
difficult in TAFs. Will use generous duration tempo groups and
amend when convection becomes more certain. Expect storms to
diminish with loss of heating, though there remains enough
forcing in moist environment to keep showers/rumble of thunder
going overnight especially from the mountains of NC up through
the Shenandoah valley. Plume of low level moisture will also
work up the mountains and foothills with some low stratus/fog
affecting KBCB and KROA, and possibly KLYH and KDAN as well.
KLWB may also experience some LIFR cigs/vsbys late tonight if
they get some rain then break out and cool late. Heating
tomorrow will reinvigorate convection with widespread
showers/thunderstorms affecting TAF sites from mid morning on.

Winds will generally be light outside of thunderstorms.

.Extended Aviation Discussion...

Probability for showers/thunderstorms will increase associated
with southward sagging front and moisture streaming north from
the Gulf of Mexico.

Weather pattern will remain summerlike through the week.
Daily threat for numerous afternoon and evening showers and
thunderstorms with MVFR ceilings and visibilities will continue
through the end of the week.

&&

As of 940 PM EDT Monday...

Additional record warmth remains possible on Tuesday.
