Area Forecast Discussion
National Weather Service Baltimore MD/Washington DC
322 PM EDT Wed Jul 6 2022
.SYNOPSIS...
A cold front will meander over the Mid-Atlantic for the rest of the
week before a second stronger cold front chases it away Saturday.
High pressure will likely return Sunday into early next week.
&&
.NEAR TERM /THROUGH TONIGHT/...
The surface based cold front will continue to move south into
the region. Satellite imagery shows a deck of broken mid-level
clouds across the region with more breaks in sun to the far
southwest from Highland County towards Charlottesville. Upstream
of this area, showers and thunderstorms continue to rapidly
develop across West Virginia with a storm motion into our
southwest counties. With profiles continuing to moisten,
additional showers and thunderstorms are expected to develop
across this area and become concentrated and perhaps train
through the evening. Therefore, have expanded the flood watch
for the potential for flash flooding across this area. For the
rest of the FA, as daytime heating is maximized and another
shortwave progresses through amidst the northwest flow this
afternoon, convection will increase in coverage.
Uncertainty arises headed into this evening with regard to
shower and thunderstorm coverage. With the surface boundary
sagging south across the FA, guidance signals at enhanced
convergence along the boundary somewhere in the vicinity of the
Mason-Dixon line towards central Virginia. PWs will approach or
exceed 2" with easterly flow developing along the low levels of
the atmosphere. Storm motions are rather slow and progged to
parallel the frontal boundary. This could result in an enhanced
training component until the cold pool becomes dominant. An
additional component is the upper-level jet moving through with
the right entrance region passing through leading to increased
diffluence aloft. Timing for this is shortly after sunset. Given
the overall setup, the flood watch for the potential for flash
flooding has been expanded into parts of the eastern panhandle
of West Virginia, central and northeast MD, and much of the
Baltimore/Washington Metro areas. This area has the best overlap
with lowered FFG to warrant a Flood Watch for the potential for
flash flooding where the best low FFG/high QPF signals overlap.
FFG is notably higher south of I-66 in Virginia. Will continue
to monitor latest mesoscale trends through this evening, but the
hydro threat likely persists through much of the overnight
given efficient warm rain processes and low-topped convection is
able to sustain itself.
Given the CAPE/modest shear space present, any storms that do form
may have a conditional severe risk (mainly wind, but some hail or a
brief spin up can't be ruled out, though low-level shear is notably
less today than yesterday).
Temperatures remain near seasonal levels through tonight with
lows in the 70s outside the higher terrain.
&&
.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
The aforementioned frontal boundary will continue moving
southward on Thursday. The front will start to weaken, with the
moisture remaining in place even behind the front, though
columns are slightly drier than Wednesday. Overall flow remains
weak, though the potential for an isolated severe storm is
certainly possible Thursday into Friday. Attention will be
focused upstream to the northwest for any MCS development that
could track into the local region given sustainable instability.
The other concern is flooding due to repeated rounds of showers
and thunderstorms through the end of the weak. Individual model
guidance continues to differ significantly, though the overall
signal for periods of potentially heavy rain certainly exist.
Will continue to monitor.
&&
.LONG TERM /SATURDAY THROUGH TUESDAY/...
Unsettled conditions continue into Saturday for at least the
southern half of the area as the shortwave continues to push the
front southward. This will bring a few showers and storms to areas
south of I-66 during the afternoon hours.
High pressure then sets up over the northeast on Saturday night into
Sunday. This will bring an onshore flow into the region with below
normal temperatures and slight chances for a few showers and some
drizzle, along with abundant clouds, especially south of the
(-66 corridor again.
High pressure pushes offshore into Monday and 500mb heights begin to
rise as a brief upper ridge builds overhead leading to quiet
weather. High temperatures remain below seasonal averages.
The next cold front will push through towards the middle of the
week, perhaps on Tuesday, bringing the next chance for unsettled
weather. That pattern looks to continue for several days
thereafter.
&&
.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
Persistent light NW flow is expected through this evening,
becoming light and variable tonight as a front sags southward.
Additional restrictions are likely (1) in shower and
thunderstorm activity (mainly later this afternoon through this
evening, though can't be ruled out a few hours on either side),
and (2) lower CIGs/patchy fog overnight into the morning hours.
Similar conditions are expected Thursday into Friday, with a
relatively higher chance of restrictions Thursday night.
Sub-VFR conditions possible at times on Saturday, particularly at
CHO where a front will lead to increased chances for showers and
storms during the afternoon hours.
Residual cloudiness may continue into Sunday as well, mainly at CHO,
as an onshore flow sets up into the region.
Dry conditions return by Sunday night into Monday.
&&
.MARINE...
Generally light W/NW flow is expected through the evening,
becoming variable tonight and somewhat erratic through the end
of the week as a front lingers overhead. Gusty winds, frequent
light, heavy rain and perhaps a waterspout are possible with and
thunderstorms - the likelihood of which will linger much of the
rest of the week.
A few thunderstorms may be possible across the lower portions of the
Potomac River and Chesapeake Bay on Saturday afternoon as a cold
front lingers nearby. Cannot completely rule out the possibility of
an SMW being issued.
Aside from that, high pressure builds in behind the showers and
storms Saturday night. SCA's may be needed for the open waters for
the later part of the weekend, but otherwise fairly calm conditions
for the long term period for the waters.e waters.
&&
.HYDROLOGY...
A cold front will sag slowly southward into the Mid-Atlantic
through tonight. Aloft, a strong and somewhat drawn out
shortwave will move along the front in W/NW flow. Although the
exact placement of the front and heaviest rainfall is still
somewhat uncertain, some enhanced convergence along with PWs
rising above 2" should overlap areas with lower FFG resulting
in a risk for flash flooding. Additionally, storm motions may be
slowed some due to weakening low-level flow, and may train
roughly parallel to the surface front.
The most likely time period for flash flooding is this evening
into the overnight, but thunderstorms producing heavy rain
will develop through the remainder of the afternoon as heating
commences, and could linger well into the night given forcing
from a passing upper jet streak.

The Roanoke radar (KFCX), 166 km away, was scanning. The volume nearest the first event began at 19:50 UTC.
6 thunderstorm wind, 1 hail. Local standard time, as filed.
Wind damage was reported around Churchville. Siding was torn off the side of a home. A tree blew down onto a car on US-250 Churchville Avenue near the intersection with Eastwood Drive.

In this area, a few hundred yard swath of trees snapped; most were healthy pine trees, and virtually every tree was snapped in half, all laying in the same direction. Elsewhere, a tree blew down onto a car on Devon Road; multiple trees and power lines blew down on Aiken Street; a large tree limb punctured the roof of a home on Garland Drive; several large trees blew down on Selma Boulevard, including a few into a house; several large pine trees snapped on Stonewall Circle and Knollwood Drive; trees blew down on Blair Street; numerous trees blew down on Poplar Street and North Drive. Some buildings suffered minor roof and siding damage around the city, as well.
Quarter size hail was reported in the City of Staunton.
Several trees blew down in the 100 block of First Street.
Several trees blew down around Fishersville in east-central Augusta County.
Tree damage was reported near Lyndhurst southwest of the City of Waynesboro, including a tree that blew down on VA-664 Lyndhurst Road.
About a dozen trees and large tree limbs blew down onto wires taking down a few poles near the intersection of VA-642 Hoadley Road and Purcell Road. A few other trees blew down in neighborhoods nearby.
