Area Forecast Discussion
National Weather Service Blacksburg VA
752 PM EDT Sat Jul 17 2021

.SYNOPSIS...
A cold front will continue to cross the area tonight.
An upper disturbance moving across the area will keep showers
and thunderstorms in the forecast Sunday afternoon and evening.
A second front passes through the area Wednesday and Thursday.
The passage of this front will introduce slightly cooler
temperatures, and lower humidity.

&&

.NEAR TERM /THROUGH SUNDAY/...
As of 650 PM EDT Saturday...

     Showers and storms to continue through sunset then start to
wane in coverage...

Areas of showers and storms continue to be located within two
distinct regions. Across our eastern counties, currently
exiting the region, are clusters of showers and storms along a
lee trough that is now shifting eastward. Precipitation across
the western half of the region is immediately in advance of an
approaching cold front, where some showers and storms are now
arriving within an airmass still rich in instability and capable
of sustaining, if not outright promoting, convective
development through the time of sunset. After sunset, coverage
across the region is expected to decline, but not end abruptly
thanks to the approach of the cold front.

Have adjusted hourly temperatures, dew points, winds/gusts, and
sky cover to better reflect the latest observations and expected
trends through the evening hours.

As 130 PM EDT Saturday...A cold front will continue to cross the area tonight.
An upper disturbance moving across the area will keep showers
and thunderstorms in the forecast Sunday afternoon and evening.
A second front passes through the area Wednesday and Thursday.
The passage of this front will introduce slightly cooler
temperatures, and lower humidity.

A closed upper level low will move east from the Great Lakes to
Lake Erie/Huron this afternoon and evening. An upper level
trough will extend south from the low tracking across the Ohio
and Tennessee Valleys into this evening. The cold front
associated with this system will slowly move to the southeast
across the Ohio Valley this afternoon. Since the flow behind the
upper trough is zonal, the cold front will not move into our
region until Sunday.

Jet dynamics with the low is best across northern Virginia into
Pennsylvania, but that will not exclude the area from getting
some strong to severe storms today. In our area, we will have a
lee trough and with the help of afternoon surface heating,
numerous storms are possible this afternoon. With moderate to
strong instabilities and weak shear, multicellar disorganized
storms are expected, gelling into line segments going into this
evening. SPC has a Marginal Risk for storms producing damaging
wind gusts for the area today. As of writing this discussion,
the probability of a Severe Thunder Watch for the area is 20
percent.

Some of the storms today will produce heavy rain as PWATS range
between 1.50 to 1.80 inches today. These PWATS are around 2
standard deviations above normal for this time of year. Slow
moving storms with high rainfall rates could lead to localized
flash flooding this afternoon and evening. Overnight tonight,
storms and rainfall intensity will wane, but as the front
approaches, on-going isolated showers will likely persist into
Sunday morning.

A second upper level trough will enter the Ohio Valley Sunday.
This trough will push the cold front into the area. Today's
convection should remove most of the instabilities from the
environment so that Sunday's storms will not be as intense. The
best chance for moderate to strong convection and heavy rain
will be along the NC/VA border southward.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/...
As of 1230 PM EDT Saturday...

A slow moving west-east oriented cold front will sag southward
toward the VA/NC border by Sunday night. Broad upper troughing
will remain over the eastern U.S. Scattered showers and isolated
thunderstorms will remain possible in the overnight along/near
the frontal boundary. With daytime heating Monday afternoon,
should see more scattered storms develop, with best coverage
along and south of the VA/NC border. Most activity diminishing
Monday night. Front will continue to drift south and expected to
be far enough south where most areas should be dry on Tuesday.
An isolated shower/storm possible Tuesday afternoon, mainly
confined to North Carolina.

Temperatures will remain below normal across the entire area
Monday with considerable cloudiness and some rain/storms , but
should recover a bit closer to normal by Tuesday as clouds clear
and the front moves further south.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
As of 1240 PM EDT Saturday...

Little change expected in the synoptic pattern. Broad upper
troughing will persist across the eastern U.S. with the early
week frontal system stalling across the southeastern U.S., but
remaining close enough to potentially tease the southern parts
of the CWA with deeper moisture and possibly a few
showers/thunderstorms during afternoon heating.

By Wednesday, another frontal system will drop southward from
the Great Lakes into the Mid-Atlantic and Ohio Valley. Moisture
will be more limited with this system than with the early week
frontal system, but given mid-July strong heating and upper
troughing/short wave energy, expect scattered
showers/thunderstorms to develop during this timeframe.

Dry conditions expected Thursday behind the front. Another
frontal system approaches in a similar manner by the weekend,
once again increasing the chances for rain and thunderstorms for
Friday/Saturday.

&&

.AVIATION /00Z SUNDAY THROUGH THURSDAY/...
As of 745 PM EDT Saturday...

Primarily VFR conditions continue across the area. Local and
brief sub-VFR vsbys and cigs are occurring where showers and
storms are the heaviest. Winds are also variable and gusty in
and around the storms.

Overnight, we are expecting convection to dissipate gradually
after sunset and sub-VFR ceilings develop across mainly the
mountains with VFR remaining east. Mountain and river valleys
likely will develop fog, likewise areas where substantial rain
occurred Saturday afternoon and evening.

After sunrise Sunday, look for gradual improvement to VFR for
all locations by mid-day. While winds will generally be light
and variable tonight, outside area of thunderstorms, look for
winds to increase Sunday from the west or northwest to around 5
to 8 kts, before dissipating around sunset.

Extended Aviation Discussion...

By Tuesday the boundary will be south of the region with cooler
and drier weather and a return to widespread VFR conditions.
Scattered MVFR storms are possible Wednesday and Thursday. Some
drier air will arrive for Friday.
