Area Forecast Discussion
National Weather Service Baltimore MD/Washington DC
952 AM EST Sun Dec 19 2021

.SYNOPSIS...
An area of low pressure will develop along a cold front to our
south and track south of the region today. High pressure returns
tonight through at least Tuesday with seasonable temperatures
persisting through at least the middle of next week. Another
area of low pressure will slide by to our south around the
middle of the week.

&&

.NEAR TERM /THROUGH TONIGHT/...
A wave of low pressure which developed along the front to our
south will slowly pull away later today, with any lingering
showers ending and skies clearing but the gusty wind
continuing. It will feel chilly compared to recent days with
temps staying in the 40s and wind chills in the 30s all day
long. However, this is actually near average for mid- December.
Overnight lows tonight will also be a significant departure from
recent nights, dipping back into the low 20s for most (low 30s
over DC/Baltimore metros). However, again this is near average.

&&

.SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/...
High pressure will bring average temperatures and dry
conditions Monday and Tuesday. Lows Monday night and Tuesday
night will again be in the 20s for most. Highs Monday and
Tuesday will be in the 40s for most, near or slightly below
seasonal normals, but with lighter winds and sun.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
Our stretch of relatively quiet weather will continue into the
long term period.

By Wednesday morning, a shortwave embedded in the northern
stream will be situated over the Great Lakes. Further south, a
closed upper low in the southern stream will be located over
Florida. The northern stream system will pass to our north with
little consequence locally. The southern stream system will have
an associated area of low pressure at the surface that will
track along the Carolina coastline and then off to our southeast
during the day on Wednesday. Guidance differs with respect to
how close to the coast this low will track. At a minimum, it
should be able to throw some high cloud cover into the area,
especially during the morning hours. If it were to take a track
toward the northwestern envelope of the guidance, some showers
could be possible along and southeast of I-95, but most of the
ensemble and deterministic guidance keeps the area dry.
Temperatures will run slightly above normal on Wednesday, with
highs in the upper 40s and lower 50s.

As the low pulls away from the area winds will turn
northwesterly, allowing for a brief shot of cold advection.
Temperatures will only drop back to near normal levels on
Thursday, with highs in the lower to middle 40s. Mostly sunny
skies are expected as high pressure builds in at the surface.

A disturbance will rapidly eject from the Rockies toward the
Great Lakes Friday into Friday Night. High pressure should hold
strong during the daylight hours, keeping conditions dry, but
cloud cover should be on the increase through the day.
Temperatures will moderate to slightly above normal again, with
highs in the upper 40s and lower 50s. Various sources of
guidance differ with respect to the finer scale details Friday
night into Saturday, but most signs point to a strong area of
low pressure tracking into the Great Lakes region. This will
leave us on the warm side of the system. Some warm advection
precipitation may be possible across the area Friday night into
Saturday, but it's also possible that locations could remain dry
if the low tracks far enough to our northwest. Temperatures
will be well above normal on Saturday, with temperatures in the
50s and 60s.

&&

.AVIATION /15Z SUNDAY THROUGH THURSDAY/...
Winds will gust 20-30 knots today, but should subside tonight
into Monday as high pressure builds overhead. VFR conditions are
expected at this time as the cold front has pushed through the
region with rapidly improving CIGs in its wake.

VFR conditions with lighter winds continue Monday and Tuesday
as high pressure dominates the weather pattern.

VFR conditions are expected on both Wednesday and Thursday. If
a coastal low to our southeast were to track a bit closer to the
area than expected, there could be some sub-VFR ceilings
Wednesday morning.

&&

.MARINE...
Occasional gale gusts have necessitated a gale warning for the
middle bay and lower Potomac. Expect winds to diminish a bit
this afternoon but a second boundary will likely result in a
resurgence this evening before diminishing for good later
tonight into Monday. Therefore, issued a single warning for both
surges.

Winds will then diminish further Monday morning through
Tuesday, with nor further marine hazards expected.

SCA conditions appear possible in northwesterly flow on
Wednesday. Sub-SCA winds out of the north are expected on
Thursday.
