Area Forecast Discussion
National Weather Service Baltimore MD/Washington DC
858 PM EDT Thu Jun 6 2024

.SYNOPSIS...
-- Changed Discussion --
Dry conditions are forecast for Friday into Saturday as high
pressure builds over the region. A slow moving upper trough
approaches the area from the Great Lakes Saturday night into
Sunday leading to more unsettled conditions.

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
-- Changed Discussion --
A cold front was crossing I-95 as of 9 PM EDT. The mid/upper
trough axis will cross later this evening, and with some
residual instability a few showers or a thunderstorm could still
pop up until around midnight, but will likely be sub-severe as
diurnal stabilization sets in.

Some passing mid level clouds are anticipated overnight with low
temperatures generally in the 60s (except mid to upper 50s west
of the Blue Ridge).

.SHORT TERM /6 AM FRIDAY MORNING THROUGH SATURDAY NIGHT/...
Dry conditions expected Friday and Saturday as large surface high
pressure moves across the region. A large upper trough remains
enough to our north through Saturday afternoon, but starts to dip
south closer to our area Saturday night. This could bring a few
showers to the Alleghenies for the second half of the weekend.

Afternoon highs will be in the upper 70s to mid 80s each day, with
overnight lows in the upper 50s to mid 60s.

&&

.LONG TERM /SUNDAY THROUGH THURSDAY/...
Our area will remain in a nearly zonal flow aloft between upper-
level low pressure over New England/southern Canada and the
subtropical ridge over the southern CONUS. A westerly downsloping
flow behind a cold front will allow for dry and breezy conditions
along with low humidity for Saturday.

An upper-level disturbance and re-enforcing cold front will move
through Sunday, bringing the chance for showers and thunderstorms.
Coverage will most likely be isolated to scattered and instability
will be limited, but given a stronger wind flow aloft there could be
some stronger storms with gusty winds.

The upper-level trough will dig south for the early portion of next
week, bringing cool and unsettled conditions.

&&

.AVIATION /00Z FRIDAY THROUGH TUESDAY/...
-- Changed Discussion --
A pop up shower or thunderstorm is possible through late
evening, but confidence is too low to include TS in the TAFs.

Dry conditions are expected overnight behind the cold front as
southerly winds shift to the west. After that, VFR conditions
are expected through Saturday as high pressure builds in from
the west.

VFR conditions are expected most of the time Saturday
through Sunday. A few showers and perhaps a thunderstorm are
possible Sunday afternoon and evening.

.MARINE...
-- Changed Discussion --
High pressure builds into the region from the west Friday into
Saturday. West winds are likely to remain below SCA criteria.

Westerly winds on Sunday turn northwest behind a cold front. Winds
over the waters are expected to stay below SCA criteria. Showers and
thunderstorms on Sunday could bring stronger gusts to the waters in
the afternoon.

&&

.TIDES/COASTAL FLOODING...
With a steady southerly flow in place across the region, tidal
anomalies have been on the increase. A cold front crosses the
area this evening, with the resulting west winds causing tidal
anomalies to drop by tonight, though the more sensitive tidal
locations will make a run at minor tidal flooding for the
morning tidal cycle.
