Area Forecast Discussion
National Weather Service Blacksburg VA
246 PM EDT Mon Aug 6 2018

.SYNOPSIS...
High pressure was centered over the southeastern United States
providing typical summer weather conditions with a daily threat
for mainly afternoon and evening thunderstorms and near
seasonal temperatures. A weak cold front will approach from the
west Wednesday bringing a better chances for organized storms
to the region.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
As of 245 PM EDT Sunday...

An upper level low off the Virginia coast will provides
subsidence to areas east of the Blue Ridge, primarily north of
Mount Airy to Danville, keeping dry conditions through Tuesday
afternoon. As deep westerly flow subsides while the low move
further offshore late tomorrow afternoon, a lee trough and
diurnal heating will generate scattered showers and
thunderstorms into the evening. Other than a few thunderstorms
tomorrow afternoon, the only weather hazards for the foothills
and piedmont counties will be patchy dense fog along the rivers
in the morning and warm humid conditions with heat indices in
the mid to upper 90s in the afternoon.

The mountains will have a better chance to see showers this
evening and again tomorrow afternoon. A stationary upper level
ridge, situated over the southeastern Gulf states, has stretched
northward into the southern Ohio Valley today. The outer ring
of this ridge sits over southwest Virginia (Bluefield) to the
northwest North Carolina mountains/foothills. A weak wave with a
cluster of storms will track across this area this afternoon
then dives south into western North Carolina late this afternoon
and evening. Any orographical showers across the rest of the
mountains will fade with lose of heating this evening. Models
are not showing any waves coming around the ridge overnight,
therefore lowered PoPs across the area after midnight. Storms
this afternoon/evening are capable of producing heavy downpours
which could lead to localized flooding. There is also a threat
that any storms forming this afternoon could also produce wet
microburst. The threat level for flooding or severe weather is
low, but not zero. Patchy dense fog is likely along the rivers
of the Greenbrier and New River Valleys and also in area that
see rain today.

The southeast Gulf coast ridge remains stationary tomorrow but
becomes flat across the southern Ohio Valley into Virginia.
There does not appear to be any waves coming across the
mountains tomorrow, however moisture and instabilities increase
as a cold front approaches the region. With an uptick in
ingredients for storms Tuesday afternoon, more areal coverage of
showers and thunderstorm are expected west of the Blue Ridge.
Storms will likely track west to east and again have the
capability to produce heavy downpours and/or wet microbursts.

Temperatures will be a few degrees above normal tonight into
Tuesday. Overnight lows will remain muggy from the 60s west of
the Blue Ridge to the low 70s east. Highs across the mountains
will warm into the 80s with low 90s east.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY NIGHT/...
As of 150 PM EDT Monday...

500 MB heights begin to lower on Wednesday with a short wave
reaching the area late in the day. Will be well into the right
rear quadrant of a 60 knot upper jet by that time. A bulk of the
lift will be offshore by late Thursday. Consensus of guidance
does not show much change in temperatures but surface dew points
will be dropping for Thursday.

850MB winds are out of the west even ahead of the front which
will result in the better coverage of showers and thunderstorms
over the mountains. Significant differences in the GFS and
particularly the NAM are suggesting a pre-frontal line of
showers and thunderstorms that crosses the mountains and
foothills and will be east of Lynchburg and Danville by evening,
but showed significant difference in the amount of placement of
low level moisture behind the front on Thursday. Threat for
severe thunderstorms is marginal based on expected instability
and shear but probability of heavy rain remains due to
precipitable water values again approaching two inches.

Confidence was average for all elements, with the exception of
clouds and temperatures on Thursday which is below average.

&&

.LONG TERM /FRIDAY THROUGH SUNDAY/...
As of 155 PM EDT Monday...

Synoptic scale pattern becomes more amplified by Saturday with
a closed upper low forming somewhere in the vicinity of the Ohio
Valley by the end of the weekend. This puts the Mid Atlantic
region in southwest flow Saturday through Monday with short wave
energy coming through the base of the trough into the area on
Saturday. No big deviations planned from the blended guidance.
Temperatures will be near to slightly above normal this time
frame.

Confidence was average for all elements Friday and below
average on Saturday through Monday.

&&

.AVIATION /19Z MONDAY THROUGH SATURDAY/...
As of 130 PM EDT Monday...

Generally VFR through the 24 hour TAF period, with the
following two exceptions...

Daytime heating and cloud buildups over the mountains will
result in widely scattered SHRA/TSRA from 18Z/2PM-00Z/8PM.

Development of mountain/river valley fog between 06Z/2AM-
daybreak along the rivers with high probability of LIFR at KLWB
and KBCB. Elsewhere fog expected to be patchy ground fog.

Winds through the period generally light and variable except
for outflow near shra/tsra.

Extended...

Summer pattern will feature mainly VFR. Any sub-VFR will be
associated with scattered mainly afternoon and evening shra/tsra
and development of early morning fog/stratus in the mountain
valleys...all of which are temporary.

Best coverage of storms will occur mid-week (Wednesday)
associated with an upper level trof and weak surface cold front.
The fog/stratus should be limited to pre-dawn hours and
confined mainly to the mountain river valleys with impacts to
KBCB/KLWB.
