DHOF

Area Forecast Discussion
National Weather Service Baltimore MD/Washington DC
541 PM EDT Tue Jun 20 2023

.SYNOPSIS...
Low pressure to the south will continue to lift northward through
the end of the work week. Associated cold front likely will impact
the Mid-Atlantic through the weekend. By early next week, an
additional cold front pushes further east.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
Shower activity has been fairly tame early this afternoon with
even some light clearing west of the metropolitan areas. These
breaks in clouds will be shortlived as a plume of moist air
moves further north across the area as a result of an upper
level low moving north into the area. A few, isolated
thunderstorms are possible across the central Shenandoah Valley
into the central Virginia Piedmont for the remainder of the
afternoon. Further north, shower and thunderstorm chances
decrease. Temperatures will continue to climb a few degrees into
the upper 70s for the lower elevations with 60s in the
mountains.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH THURSDAY NIGHT/...
Wednesday into Thursday continues to display a prolonged stratiform
rain event. As the upper level low pressure system moves further
north, the shield of precipitation will follow along. Latest
guidance continues to have increased PWAT's of 1.3 to 1.8
inches given the easterly flow and additional moisture plume
coming in from the south. Instability looks limited based on
various model soundings and guidance, with CAPE only getting to
a couple hundred joules per kilogram. Flooding still looks
possible for the area, especially across portions of central VA
where they already received 1 to 2" of rain a day ago. While
most of the precipitation Wednesday into Thursday looks to be
beneficial given the antecedent conditions, there is an isolated
threat for instances of flooding.

Later Thursday afternoon, instability may begin to pick back up for
the area and may allow for a better chance for locally heavy
downpours and isolated thunderstorms. This, along with previous
rainfall for the area may add additional opportunities for localized
flooding impacts. Temperature-wise, highs will be in the low to mid
70s for areas along the waters with 60s further west given the
increased cloud coverage and easterly flow. At night, lows should
drop into the upper 50s to 60s.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
The long term period will be mostly unsettled weather as upper level
troughing and low pressure dominate the synoptic pattern. On Friday,
upper level ridging will continue eroding to our Northeast as a
closed upper level low moves northward to our west. Southerly flow
will usher in warm and moist air to the region providing PWATS > 1.5
inches. At the surface, a cold front will track through our area
Friday afternoon and into Saturday morning. As low pressure moves
over the region this weekend, showers and thunderstorms are possible
each day. Localized heavy precipitation is possible during
convection, but due to drought, rainfall looks to be beneficial at
this time.

As low pressure departs the Northeast on Monday, upper level
troughing centered over the Great Lakes will dig into the Ohio River
Valley on Monday. An associated cold front will be approaching the
area on Monday continuing shower and thunderstorm chances.
Temperatures throughout the long term will increase by a few degrees
each day warming to normal or just above normal on Monday.

&&

.AVIATION /22Z TUESDAY THROUGH SUNDAY/...
Ceilings continue to fluctuate between VFR and MVFR
for most of the terminals this afternoon aside from the KBWI/KMTN
terminals. CIGs likely continue to fall through this evening and
evening overnight into Wednesday morning. Winds will continue to be
elevated this afternoon and evening before diminishing briefly
tonight before increasing significantly during the day on Wednesday.
Gusts of 15 to 25 knots are possible throughout the period.
Thunderstorm chances increase on Thursday so there may be additional
restrictions during the afternoon and evening as a result.

An area of low pressure moving to the west of our area will increase
chances for showers and thunderstorms at all terminals on Friday and
Saturday. Conditions could deteriorate to sub-VFR during
precipitation.

&&

.MARINE...
Onshore E/NE flow is expected through early Thursday. Winds will
increase tonight through Wednesday, likely peaking Wednesday midday
through Wednesday evening/night from south to north. Gale conditions
are possible Wednesday into Wednesday night. Rain showers are also
expected to increase Wednesday and Wednesday night, though overall
thunderstorm potential looks isolated/low during this time.

Thunderstorm potential will increase heading into Thursday as winds
shift around to the south.

Southerly winds on Friday will likely be SCA criteria in the
afternoon. Winds are expected to decrease to sub-SCA criteria by
Saturday morning and will shift to out of the west/southwest.

&&

.TIDES/COASTAL FLOODING...
Onshore flow will continue through Thursday. Water level anomalies
continue around 1 to 1.5 feet. The greatest surge is expected to
build later Wednesday into Thursday as the onshore flow strengthens.
Have issued Coastal Flood Warnings, Watches, and Advisories for high
tide cycles at various locations through mid-week. Additional
headlines are likely given the persistent onshore flow. Confidence
in moderate tidal flooding is highest further south in the
Chesapeake Bay, hence the warnings/watches for St Mary's County.

Guidance does show some decrease in water levels toward the end of
the week, although southerly flow may keep enough water around for
some additional minor flooding.

&&

.EQUIPMENT...
KLWX will be down for approximately ten days for an important
upgrade. Technicians will refurbish and replace the pedestal,
one of the most critical components of the radar, which is
necessary for antenna rotation and positioning to capture data
in all directions. The components are extremely heavy and will
require the radome to be removed by crane and replaced when the
work is completed. Estimated return to service is June 30th,
barring any unexpected issues.

During the downtime, adjacent radars will be available,
including: Wakefield, VA (KAKQ), Roanoke, VA (KFCX), Dover, DE
(KDOX), Charleston, WV (KRLX), Pittsburgh, PA (KPBZ), State
College, PA (KCCX), and Fort Dix, NJ (KDIX)...also FAA Terminal
Doppler radars for Dulles (TIAD), Reagan National (TDCA),
Thurgood Marshall BWI (TBWI), and Joint Base Andrews (TADW). For
