Area Forecast Discussion
National Weather Service Blacksburg VA
251 PM EDT Sun Jun 24 2018

.SYNOPSIS...
A weak cold front will push south across our area tonight, and
stall to our south, keeping unsettled weather in our area
Monday. High pressure aloft will then build over the eastern
U.S. during the later half of the week resulting in hotter and
humid conditions along with the threat of diurnally driven
showers and storms.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 250 PM EDT Sunday...

Early this afternoon an east-west oriented surface boundary was
noted across central WV into northern KY. In the upper levels, a
shortwave was spinning across northwest PA with a vort lobe
extending south of this feature into VA.

1000-1500 k/kg MLCAPES to the south of the boundary and 20-40kt
Effective bulk shear values suggest a few storms that form along
the boundary and south may produce locally damaging winds, but
with a deep west flow, coverage should remain limited.

With subsidence arriving this evening in the wake of this
shortwave trof, convection should diminish across most of the
region by 23Z (7 PM).

Tonight, our focus turns to the MCV currently spinning across
Missouri, which is expected to reach the southern Ohio Valley by
12Z Monday. In advance of this system, clouds will increase
across the west and patchy fog will be possible. Kept small POPS
in the far southwest as a strengthening low level jet
intersecting with a front across the southern portion of the
forecast area and increasing PWAT values may generate precip
just before 12Z. Kept lows on the warmer side of guidance.

Will be monitoring the potential for an MCS to south impacting
our NW NC counties Monday. Deeper moisture arrives in advance of
the approaching MCV,but instability off BUFKIT soundings at TNB
don't appear too impressive. However, with good upper level
divergence and a 850mb baroclinic zone nearby along with this
area in a favorable MCS generation area (northern edge of 500mb
ridge), increased POPs and QPF for this area on Monday.

Also, with widespread cloudiness generated by this system,
brought down high temps a few degrees, and if current signals
persist in later model runs these temps for Monday may need to
be lowered further. While the greatest chance for severe weather
Monday appears to be south of our forecast area where higher
instability is expected, if the cold front shifts slightly north
and higher CAPE values can be realized will need to monitor svr
potential in northern NC/far SW VA.

&&

.SHORT TERM /Monday Night through Wednesday Night/...
As of 140 PM EDT Sunday...

Monday night surface high pressure builds south into Virginia and
brings winds around to the east and southeast. Models have enough
upslope southeast wind and moisture below 850 mb that mountains and
foothills will have clouds much of the day Tuesday. Plan to have
more sun in the piedmont especially in the afternoon,similar to the
GFS forecast. Tuesday will be the coolest of the week due to the
clod cover and 850Mb temperatures in the +12 to +16 range.

By late Tuesday the high is offshore. Southwest low level winds off
the Gulf will bring up surface dew points and precipitable water on
Wednesday. An approaching short wave from the northern stream will
reach the central Appalachians late Wednesday. Will have relatively
higher probability of precipitation on Wednesday night, especially
in the mountains of southwest Virginia and southeast West Virginia
as this feature crosses the area.

Confidence for cloud cover and high temperatures on Tuesday is below
average. Otherwise, confidence for all elements is average.

&&

.LONG TERM /Thursday through Sunday/...
As of 140 PM EDT Sunday...

Surface low pressure crossing the Great Lakes on Thursday may
bring a weak low level boundary across the Mid Atlantic region,
and with the mean flow generally out of the southwest the
increase in low level convergence will trigger afternoon and
evening showers and thunderstorms.

Upper ridge will cover the eastern United States Friday and Saturday
with 500 MB heights around 594dm over the Ohio Valley and Mid
Atlantic region through Sunday. Models beginning to hint at an upper
low somewhere off the southeast coast during this time frame. Warm
air at mid levels, subsidence under the ridge and downslope winds
with limit thunderstorm development. Will keep probability of
precipitation low from Friday through Sunday. Temperatures will be
above normal.

Confidence for all elements is average on Thursday and above
average for Friday through Sunday.
&&

.AVIATION /19Z SUNDAY THROUGH FRIDAY/...
As of 105 PM EDT Sunday...

Widely scattered to scattered showers and thunderstorms will dot
the region through 23Z (7 pm). While there is only a slight
chance to chance a TAF site will be impacted by these showers
and storms, KLWB, KBLF and KROA are the most likely to see
precipitation, as a result a tempo group for storms was included
for the rest of this afternoon.

Breezy conditions will also be found, with gusts 20-30 kts
possible across the higher elevations.

Patchy areas of fog and stratus are again forecast to develop,
with KLWB most likely to be impacted with IFR vsbys and also
included MVFR vsby fog at KBLF.

A complex of showers and storms is expected to move into the
region from the west Monday morning. Confidence is low
on the timing and coverage of this potential area of
precipitation, but the most likely areas to experience
showers and storms will be northwest NC and far southwest VA.
VCSH conditions were included at KBLF and KBCB for tomorrow.

.Extended Aviation Discussion...

A cold front finally pushes far enough south to allow
VFR conditions for Tuesday.Isolated to scattered MVFR showers
and thunderstorms are possible by Wednesday with more isolated
nature to convection Thursday when should be back to mainly VFR.

&&

.EQUIPMENT...
As of 238 PM EDT Sunday...

The NOAA weather radio transmitter in Hinton, West Virginia that
is WXM72 and broadcasting at a frequency of 162.425 MHz is off
the air. Parts are on order to repair the transmitter, but there
is no known time of restoration. We apologize for any
inconvenience.
