Area Forecast Discussion
National Weather Service Blacksburg VA
721 PM EDT Thu Aug 6 2020

.SYNOPSIS...
A weak cold front remains stalled today into early Friday across
the area, before pushing southeast Saturday. High pressure
builds in this weekend with return to typical summer weather.

&&

.NEAR TERM /THROUGH FRIDAY/...
As of 715 PM EDT Thursday...

Convection this evening is almost a carbon copy of yesterday
with a line of storms tracking across the area along and south
of the VA-NC border. Strong storms capable of producing gusty
winds and large hail may continue for a few more hours this
evening. However, heavy rain threat across the south and over
the piedmont will likely hang around through at least midnight.

It does not appear we will see substantial clearing this
evening with a stalled boundary remaining over the region
tonight. So for now, will have patchy fog developing a few hours
after the rain comes to an end.

As of 245 PM EDT Thursday...

Thunderstorms have developed early this afternoon in the
mountains west of the Blue Ridge and then to our east further
out into the piedmont with a lull for the local area east of the
Ridge. Storms have been prolific rain producers with a couple
of storms pulsing up enough to generate some large hail.
Anticipate the primary threat through this evening will reside
with flash flood potential with a secondary threat of isolated
wind damage and possibly large hail. Anticipate activity will
eventually develop east of the Ridge as outflow boundaries
converge to generate new convection into early tonight before
activity wanes late. Friday may present a similar situation to
today as the axis of the upper trof still remains to our west.

Conditions will be seasonably warm though on the humid side.
Lows tonight will be in the upper 60s to around 70 east of the
Blue Ridge, low to mid 60s west. Highs tomorrow will be in the
mid/upper 80s east, mid/upper 70s west.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT/...
As of 1230 PM EDT Thursday...

Upper level trough moves through the Mid-Atlantic Friday night
into Saturday, bringing in a surface high. Despite this change
in pattern, a few isolated storms remain possible for Saturday
afternoon, given steep lapse rates. Any development will be
difficult to pull off though, given dry air aloft.

A weak disturbance Sunday will work with the slowly returning
moisture behind a stalled front to our south to allow for some
isolated showers and thunderstorm activity. Temperatures by this
point start to make their aim at returning to above average,
with areas east of the Piedmont forecast to hit 90 degrees as
850 temps swell to +20C in the afternoons.

Monday will be a near repeat to Sunday with diurnal heating
working with a weak disturbance to try and get convection going
in the afternoon, but staying mostly isolated. Temperatures also
continue their gradual warming.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
As of 1230 PM EDT Thursday...

Typical summertime pattern remains in place through the
forecast period with a broad areas of high pressure sticking to
the southern U.S. All the while, the jet stream remains tied up
in Canada with a trough attempting to dig down into the Great
Lakes region. This pattern will keep diurnal convection going
through next work week. All the while, the region of high
pressure will help with transport of an above average
temperature airmass that will be keeping us toasty. The
foothills and Piedmont will continue to see 90s while the
mountains warm to the 80s. Lows range in the 70s and 60s.

&&

.AVIATION /23Z THURSDAY THROUGH TUESDAY/...
As of 725 PM EDT Thursday...

Strong storms capable of producing heavy rain and abundant
lightning will remain through at least midnight tonight. The
best coverage of storms are along and south of the VA-NC border
and into the piedmont, similar to last night. Storms moving over
an airport will quickly see IFR or lower conditions for a hour
or so.

As the rain stops across the area after midnight, patchy dense
may form. However, stalled boundary over the region may keep
clouds around to limit fog, but then an IFR/MVFR stratus deck is
then likely. Conditions improve to VFR later Friday morning
with a break in the convection before redevelopment occurs
friday afternoon.

Extended Aviation Discussion...

High pressure builds into the weekend with lesser chances of
storms. Pattern should be more typical of summer into Monday
with scattered afternoon/evening storms. Overall VFR outside
storms and late night valley fog.
