Area Forecast Discussion
National Weather Service Baltimore MD/Washington DC
304 PM EDT Fri Aug 26 2022
.SYNOPSIS...
A weak front will drop through the area tonight into Saturday.
High pressure will build over New England Sunday before moving
offshore Monday. Another front will approach by the middle of
next week.
&&
.NEAR TERM /THROUGH TONIGHT/...
Low pressure is heading into the St. Lawrence Valley this
morning with a cold front trailing toward the Ohio Valley.
Aloft, a shortwave trough is moving into the Ohio Valley. Three
areas of localized convergence have developed as denoted by
enhanced cumulus fields: near the I-95 corridor, the Shenandoah
Valley, and western Maryland. These areas will be the most
favorable for convective development over the next couple hours,
with activity drifting east to southeast with time. CAPE may
peak in the 1000-1500 J/kg range, but mid level lapse rates are
poor, there is a good bit of dry air aloft, and winds will have
a westerly (downsloping) component. Therefore activity should be
scattered at best, and weak shear will keep storms disorganized
and pulsey. 12Z HREF updraft forecasts continue to support the
idea that convection will be weak...not to mention a lot of 12Z
guidance in general is fairly sparse in coverage. The main
threats with the strongest storms will be gusty winds and brief
heavy rain, as gradual storm movement and lower longevity should
preclude any hydro issues. Meanwhile storms that form closer to
the cold front may reach the Appalachians this evening before
dissipating. Temperatures are reaching the mid 80s to around 90.
The threat for showers and thunderstorms should slowly taper off
through this evening with dry conditions likely returning after
midnight. Clearing skies along with light winds will mean another
chance for patchy dense fog late tonight into Saturday morning,
especially west of the Blue Ridge. Lows will range from the mid
60s to around 70.
&&
.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
The weak front will be pushing south through the area Saturday
morning while high pressure moves across New England, turning
winds more northerly. This will push the highest chance of a
shower or storm during the afternoon southward toward the I-64
corridor. Many models also indicate some convective development
along the Chesapeake Bay due to locally higher CAPE and the bay
breeze boundaries. Any showers and storms that do develop will
likely be fairly weak and slow moving. Since there won't be much
airmass change behind the front, highs will once again be in
the mid 80s to near 90. MOS guidance indicates potential for
dense fog across southern areas Saturday night where low level
moisture may pool.
Upper level ridging will build eastward on Sunday while the
surface high moves farther to the east. This should serve to
suppress most convective development, but a lot of guidance
indicates stray pop up showers in the warm and humid airmass.
The greatest chance appears to be in southwestern areas where
there will be a little more convergence and upslope to the low
level flow. Any activity will taper off during the evening with
patchy valley fog possible again. Temperatures won't deviate too
much from prior days.
&&
.LONG TERM /MONDAY THROUGH THURSDAY/...
An upper ridge moves overhead on Monday with Bermuda high pressure
set up offshore. This will lead to hot and humid conditions across
the region. Most areas should remain dry Monday, however this will
be a prime day for pop-up convection, particularly over the higher
elevations during the afternoon/early evening hours. Highs in the
low 90s with dew points back into the upper 60s to low 70s.
Not much relief on Tuesday as a cold front approaches for the west,
enhancing southerly return flow into the region. While the front is
not progged to push through until Tuesday night into Wednesday
morning, a pre-frontal trough is expected to develop and initiate
convection on Tuesday afternoon. There will be some decent shear in
place (around 30 kts), as well as plenty of instability in place
given highs in the mid 90s and dew points near 70. Would expect
initiation of storms out west over the higher elevations as the pre-
frontal trough develops, before pushing gradually eastward through
the evening hours.
The aforementioned cold front should push through on Wednesday, but
guidance is still a bit split on just how quickly, so maintaining
chance POPs in the forecast for now. Thinking that the best chance
for showers and storms will be in our eastern and southern zones as
the front gets hung up. Given uncertainties in how quick the front
pushes through, high temperatures forecast is a bit tough as well.
Of course the further east it gets, the larger area that see temps
in the mid 80s, compared to areas east of the front reaching the low
90s.
Do think lowering POPs for Thursday is likely given recent trends
getting the front through by then with high pressure building into
the area once again. Temperatures Thursday should cool down a good
bit into the mid 80s.
&&
.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
A weak pressure trough is located across the area this
afternoon. In a somewhat atypical situation, DCA/BWI/MTN may
have the highest chance of a shower in the vicinity through mid
afternoon along a leading subtle wind shift and the bay breeze.
MRB/CHO/IAD will have the highest chance associated with another
area of lift along the Shenandoah Valley, drifting eastward
through early evening...with uncertainty being higher how far
east this activity will make it. Felt highest confidence of VCTS
was at MRB, CHO, and MTN based on 12Z models, but amendments
are certainly likely. All in all, activity should be fairly
widely spaced and weak. Winds are quite variable this afternoon
as well due to localized features but should generally be less
than 10 kt. SCT to BKN cumulus will dissipate this evening, and
winds will become northerly by Saturday morning as a weak front
drops into the area. Fog may form near CHO and MRB late tonight
but at this time prospects for dense fog are low.
High pressure will build in from the north Saturday and Sunday.
Thunderstorm chances seem to be isolated at best each afternoon.
Fog will be a possibility during the overnight hours, especially
at CHO and MRB. Both MAV and MET MOS guidance indicate
potentially dense fog near CHO Saturday night.
Scattered thunderstorms are expected Tuesday afternoon into Tuesday
evening ahead of an approaching cold front. All terminals have a
chance to see restrictions during this time. The front then should
push through completely on Wednesday, but a few showers and storms
are possible for the eastern terminals if the front moves through
slower and is still around during peak daytime heating hours.
&&
.MARINE...
Southerly winds have increased a bit this afternoon and will
continue into this evening over portions of the bay, where an
SCA is in effect. A few thunderstorms with gusty winds will be
possible on the waters this afternoon and evening as well. A
weak front will pass to the south Saturday and high pressure
will build to the north Sunday. Sub-SCA conditions are expected
during this time. However, and isolated thunderstorm could form
near the waters each afternoon into the early evening.
Scattered thunderstorms Tuesday and Wednesday will potentially lead
to SMWs both afternoons/evenings. SCAs are also possible on both
days as southerly flow intensifies ahead of a passing cold
front.
