Severe Thunderstorm Warning 84, NWS Blacksburg, VA

Area Forecast Discussion
National Weather Service Blacksburg VA
200 PM EDT Fri Jun 13 2025

.SYNOPSIS...
A stalled frontal boundary will remain within the region through
the weekend and into next week. Several weak disturbances will
move along the boundary, resulting in scattered afternoon and
evening rain and thunderstorms through the end of next week.

&&

.NEAR TERM /THROUGH SATURDAY/...
As of 130 PM EDT Friday...

Key Messages:

1) Thunderstorms will continue into the afternoon/evening,
tapering off overnight

2) Another round of rain and storms likely Saturday.

A stalled frontal boundary is currently situated across northern
Virginia. A very warm and moist airmass is fully in place across
the region as southerly flow continues to increase. Weak forcing
today, but strong surface heating combined with abundant
boundary layer moisture has resulted in moderate instability
throughout the Mid-Atlantic. Thunderstorms have already begun to
develop over the higher terrain and coverage will likely
continue to increase through early evening. With lack of any
substantial shear, mainly expecting sub-severe slow moving
storms capable of marginally strong gusts and heavy rainfall
rates. As a result of the slow storm motions and high ambient
moisture, localized flooding will be possible due to efficient
rainfall rates.

Thunderstorms will gradually taper off around sunset and showers
and a few heavier downpours may continue through midnight. Areas
of fog will develop early Saturday.

Mostly cloudy start to Saturday, but should see breaks of sun by
late morning and into early afternoon. This should be sufficient
enough to result in CAPE values to climb in excess of 2000 J/kg
by the afternoon. Upper wave moving east from Kentucky will
provide better forcing, thus expecting slightly better coverage
of storms, along with the potential for a few stronger storms
through Saturday afternoon. Once again, main threat from storms
will be damaging winds and very heavy rainfall.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/...
As of 200 PM EDT Friday...

Key Message:

1) Rounds of showers and thunderstorms through the period.

A stalled boundary/lee trough looks to remain across the area with
added forcing from an upper shortwave approaching from the west for
Sunday. These mechanisms in an amply moist airmass will allow for
pretty widespread showers and thunderstorms to develop. Very high
PWATs of near 1.75 to 2+ inches in place will support very efficient
precip producers and aided downdrafts with hydrometeor loading.
Localized flooding looks to be the primary threat with convection.

We lose some of the upper wave energy come Monday though maintain a
very moist column. Coverage may not be quite as widespread as Sunday
but the continued threat of showers and storms with locally heavy
rain and isolated flooding remains.

Temps look to have a limited diurnal range with near to below normal
highs and above normal lows given the moist environment.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
As of 200 PM EDT Friday...

Key Message:

1) Precipitation chances continue daily.

CWA remains under broad SW flow aloft and a continued moist airmass
through midweek without much of any main feature moving through
other than some possible weak perturbations along the flow. This
will mean rounds of scattered convection each day with coverage
mainly increasing from diurnal heating unless any aforementioned
upper disturbance can focus pockets of enhanced forcing during other
times of the days. By later Thursday into Friday some guidance is
pegging in on an upper longwave trough and translated sfc cold
frontal passage though there are timing and strength discrepancies.

Wed and Thu high temps look to be the warmest with areas in the
Piedmont potentially hitting the 90 deg mark.

&&

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
As of 200 PM EDT Thursday...

Overall VFR this afternoon and evening, with the exception of
any passing thunderstorms that could result in brief reductions
of VSBY. Rain and storms will taper off in intensity and
coverage after sunset.

Fog development possible overnight, especially across the
mountains. Any fog will result in IFR/LIFR conditions until
around daybreak.

VFR returns after daybreak on Saturday with generally BKN/OVC
skies.

Winds will remain light and variable, but strong gusty winds
will be possible within any storms.

EXTENDED AVIATION OUTLOOK...

Storm chances remain elevated this weekend into early next week
as a frontal boundary stays situated to the north of the area.
Will not be a complete washout, but expect VFR interspersed
with sub-VFR cigs/vsbys in showers/storms in the afternoon and
evenings and fog during the early mornings.
