Area Forecast Discussion
National Weather Service Baltimore MD/Washington DC
254 PM EDT Sun Jun 9 2024

.SYNOPSIS...
A cold front will continue pushing southeast of the area tonight
as upper level troughing pivots over the region. High pressure
builds in over the area in the wake of the cold front, leading
to mostly dry conditions.

&&

.NEAR TERM /THROUGH TONIGHT/...
In the wake of a cold frontal passage this afternoon, winds have
shifted from southwesterly to west/northwesterly. Dry air
filtering in behind the front will allow for dry conditions this
afternoon and into the early evening. As an upper level trough
pivots over the area, a disturbance to our north will usher in
moisture later this evening. An isolated rain shower cannot be
ruled out around 00Z-02Z this evening along the Alleghenies,
but dry air should prevent any precipitation from making it east
of the Blue Ridge.

Overnight low temperatures will be in the 50s for most with
those in the metro areas staying in the 60s.

&&

.SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/...
An upper level trough will continue pivoting overhead Monday and
Tuesday as high pressure builds in at the surface. Conditions
will primarily be dry each day, however, there is a slight
chance of precipitation Monday afternoon as the upper level
trough deepens over the area. Precipitation chances are highest
for those in the southernmost portions of the forecast area and
along the Alleghenies.

On Tuesday, a frontal system and surface low pressure draped
over the Carolinas will lead to a slight chance of precipitation
in the southernmost portions of the area. Otherwise, dry
conditions are expected on Tuesday with light winds out of the
northwest.

High temperatures will be in the 60s to 70s with only those in
the metro areas possibly reaching 80. Overnight temperatures
each night will be in the upper 40s to 50s each night with
metro areas staying in the low 60s.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
High pressure will allow for mostly dry conditions on
Wednesday. A weak boundary may pass by far western MD and along the
Allegheny Front, where an isolated shower/sprinkle may fall. Highs
will be in the low to mid 80s for the lower elevations with low 70s
across the mountainous terrain. Dry conditions continue Thursday
into Friday with high pressure slowly moving further offshore and
warm, moist southwest flow building in.

A warmer airmass will introduce low to mid 90s into the area by
Thursday and Friday afternoons ahead of a weak cold front moving in
from the west. Cannot rule out a few showers or even isolated
thunderstorms Friday afternoon and evening, especially across
western and north-central MD. The cold front passes by early
Saturday morning and brings in a reprieve of 90s, with mid to upper
80s expected for the weekend with mostly dry conditions expected.

&&

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
VFR conditions today through Tuesday night. As a cold front
moves through the area, winds are shifting from southwest to
northwest. Winds will remain out of the northwest this afternoon
and into the evening, gusting around 20 knots at all terminals.
Winds diminish overnight and are expected to remain out of the
northwest Monday blowing 5 to 10 knots. Gusts up to 20 knots are
expected at KMRB Monday afternoon. Winds diminish further on
Tuesday, blowing around 5 knots out of the northwest.

VFR conditions are expected Wednesday into Thursday as high pressure
lingers near the area.

&&

.MARINE...
Small Craft Advisories remain in effect through this evening
with winds gusting out of the northwest around 20 knots. Winds
diminish tonight through Tuesday. Wind gusts up to 15 knots are
possible Monday afternoon in the northern portions of the
waters, with winds remaining light Monday night into Tuesday.

Sub-SCA winds are expected Wednesday into Thursday as high pressure
influences the waters, leading to light southerly flow by Thursday
afternoon and evening.

&&

.TIDES/COASTAL FLOODING...
Behind a cold front early this afternoon, winds have become more
westerly or north-westerly and have allowed tidal anamolies to
lessen with no real threat for coastal flooding over the next
several days.

&&

.LWX WATCHES/WARNINGS/ADVISORIES...
DC...None.
MD...None.
VA...None.
WV...None.
MARINE...Small Craft Advisory until 9 PM EDT this evening for
     ANZ530>543.
