Area Forecast Discussion
National Weather Service Baltimore MD/Washington DC
929 PM EDT Tue Oct 8 2024

.SYNOPSIS...
High pressure will gradually build into the region through
Friday morning. A dry reinforcing cold front moves through
Wednesday night. A weak front approaches the area Sunday with
minimal rain chances with it.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
Another dry, mostly clear night as high pressure continues to
influence the area. Cannot rule out some patchy fog out west in
the mountain valleys. Overnight lows will drop down into the 40s
for most areas. Cannot rule out a few areas along the Allegheny
Front getting into the mid to upper 30s for a few hours.
Isolated patches of frost may develop in the aforementioned
areas but the zone coverage is likely not enough to warrant a
Frost Advisory just yet given the temperatures as well as the
slightly elevated winds coupled with some passing high clouds
throughout the night.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH THURSDAY NIGHT/...
NW winds pick up Wed afternoon with good daytime mixing ahead
of a dry cold front. High pressure then builds over the region
Wed night through Fri morning with cooler temperatures expected,
especially at night. The coolest day will likely be Thursday
before a gradual warmup builds into the weekend. Frost
Advisories may be needed for portions of the Allegheny Front
Wednesday night and Thursday night especially.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
Dry conditions and sunny skies are expected Friday and Saturday with
high pressure settling over the southeast. High temperatures on
Friday will be in the upper 60s to low 70s with overnight lows
dipping into the upper 40s to low 50s. Temperatures warm to above
normal on Saturday with high temperatures rising into the mid to
upper 70s for most. Those at higher elevations, particularly along
the Alleghenies, will stay in the 60s. Overnight lows will be in the
50s for most.

On Sunday, a backdoor cold front will drop through the region with
an approaching low pressure system and associated cold front to our
west. The latter will move through the forecast area on Monday,
bringing the return of precipitation chances to the area. Slight
chance to chance PoPs are expected beginning Sunday with the
greatest chances along the Alleghenies. The I-95 corridor will
remain primarily dry, though increased cloud cover is expected. In
the wake of the frontal passage, temperatures will be noticeably
cooler. Temperatures on Monday will be in the 60s with higher
elevations staying in the 50s. Overnight lows will dip into the 40s
as those along and west of the Blue Ridge dip into the 30s.

&&

.AVIATION /01Z WEDNESDAY THROUGH SUNDAY/...
VFR conditions expected through Fri. Winds strengthen Wed
afternoon from the NW with gusts up to 20 kt. Winds diminish
below 10 kt Thu evening.

Prevailing VFR conditions are expected at all terminals on Friday
and Saturday. Winds remain out of the west/northwest both days,
gusting up to 15 knots each afternoon.

&&

.MARINE...
SCA are likely Wed afternoon through Thu night in NW winds.

Winds stay below Small Craft Advisory Criteria with W/NW winds
blowing 10 to 15 knots each afternoon.

&&

.TIDES/COASTAL FLOODING...
Snapback tides will likely persist through the current high tide
cycle. This may result in a couple cycles of near-minor
threshold water levels on sensitive shoreline like Annapolis and
DC SW Waterfront. Another push of northwest winds will lead to
decreasing water levels Wednesday night.

&&

DC...None.
MD...Small Craft Advisory from noon Wednesday to 6 AM EDT Thursday
     for MDZ008.
VA...None.
