The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Baltimore/Washington wrote its last area forecast discussion before this small craft advisory went out at Jan 4, 9:30 PM EST, 6 hours 5 minutes earlier.

Area forecast discussion, Jan 4, 9:30 PM EST, 6 hours 5 minutes before
Area Forecast Discussion
National Weather Service Baltimore MD/Washington DC
930 PM EST Mon Jan 4 2021

.SYNOPSIS...
A weak low pressure will pass south of the region tonight into
Tuesday. A cold front will cross the region late Tuesday and
Tuesday evening. High pressure will build in for Wednesday and
Thursday before another low pressure passes to the south Friday.
High pressure again returns for the weekend ahead of another
system threatening the region next Monday.

&&

.NEAR TERM /THROUGH TUESDAY/...
On the synoptic scale, a trio of upper lows are noted in mid-
level water vapor imagery. The Mid-Atlantic region generally
sits in between these features as a shortwave tracks along the
North Carolina/Virginia border while the other systems remain in
the vicinity of New England. The 00Z KIAD sounding sampled an
atmosphere with lackluster wind fields from the surface to
300-mb with a near saturated layer up to 775-mb. This has
supported the weak radar returns which has resulted in a few
sprinkles moving toward the I-95 corridor this evening. Farther
west where colder air is in place, scattered snow showers are
possible from the Blue Ridge and Catoctin Mountains westward as
the trough slips by to the south. Ultimately there is not much
low-level forcing with the system, but there should be enough
low-level convergence to churn out such showers. Accumulations
in the valleys will be more difficult to come by given marginal
boundary layer temperatures. However, a light coating cannot be
ruled out in such locations. In terms of temperatures, mild
conditions continue for early January standards with lows around
8 to 12 degrees above climatology. This includes above freezing
numbers along the I-95 corridor from central Virginia up into
District as well as southern Maryland.

On Tuesday, as the low over southern Virginia heads out to sea,
the low over New England will approach from New York. Again,
very meager forcing, but with plenty of moisture and just a
little instability, enough for some mostly sprinkles/flurries to
occur. Otherwise, plenty of clouds and light winds on Tuesday,
with temps rebounding only to the lower 40s.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY NIGHT/...
The cold front and shortwave presently over the northern Plains
will finally help punt this whole mess away from the region
Tuesday night. This may enhance upslope snow showers, but should
put an end to flurry/sprinkle activity east of the mountains and
help clear the skies partly. It will also kick up the wind a
bit. Lows Tuesday night will be in the 20s to lower 30s.

Sunshine should return to much of the area Wednesday as high
pressure finally builds in behind the cold front and shortwave.
It will be breezy however, but the sun may help it feel less
brisk and chilly than it otherwise might. Highs will again be in
the low-mid 40s.

Mostly clear skies expected Wednesday night with high pressure.
Lows should be mostly in the 20s.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...
High pressure will be nearby for the area on Thursday. Clouds
will begin to roll in during the day as high pressure exits and
our next potential disturbance tracks NE towards the area.
Temperatures for the early part of the extended will continue to
be seasonable for this time of year. Could see the possibility
for some brief upslope snow Wednesday into Thursday along and
west of the Allegheny Front.

Surface low pressure along with a cut off upper level low will
be moving across the Deep South towards the Carolinas. Latest
guidance has the surface low reaching the Carolina coastline by
early Friday morning. For now, most model guidance keeps the
heavy source of moisture to our south with this system. As
always, tracking of this future coastal low will dictate impacts
to our area. A more northern shift in the track will increase
the likelihood for impacts in our CWA (mainly the southern
portions). If a northern shift occurs, wintry precipitation is
possible with a few depending factors favoring this setup.
Colder air would need to be nudged further south and east along
with the track of the low. For now, model guidance keeps our
chances minimal but non-zero at this time for wintry impacts for
mainly our southern areas. Will continue to track model trends
and thermal patterns for this system. As the low intensifies
Saturday, it will move offshore and high pressure will build in
for the rest of the weekend.

&&

.AVIATION /02Z TUESDAY THROUGH SATURDAY/...
Weak upper-level system crossing the region tonight and Tuesday
will result in some periods of MVFR cigs. Spotty rain/snow
showers could also occur, especially near CHO tonight and then
further north towards the metro on Tuesday, but minimal if any
impacts are anticipated. Cigs should clear out Tuesday night
behind a cold front, which will provide building high pressure
and VFR conditions for Wednesday. However, winds will gust 20-25
knots from the northwest at times as high pressure builds in.
Winds should relax Wednesday night.

VFR conditions expected Thursday with high pressure overhead.
Could see a brief uptick in NW winds as high pressure exits but
VFR conditions will continue into Friday given the latest model
guidance. A northern shift in the low pressure system to our
south would increase the likelihood for sub-VFR conditions for
Friday later in the day.

&&

.MARINE...
Light winds expected over the waters through Tuesday. Tuesday
night into Wednesday, a cold frontal passage and high pressure
building behind it should result in fairly widespread but
relatively low-end SCA conditions. These winds should diminish
Wednesday night.

No marine hazards expected for Thursday. As low pressure tracks
to our south and east, brief periods of SCA criteria winds
could penetrate our waters Friday into Friday night with
northerly winds.

&&

.TIDES/COASTAL FLOODING...
Given the weak surface winds across the region, some lower Bay
water has begun to pile up over the tidal sites. Anomalies are
running between 1.25 and 1.75 feet with has brought many tidal
forecasts into Action. Will need to monitor the Washington, D.C.
waterfront around high tide tonight with the current forecast
just short of Minor at midnight. Additionally, the next tide at
Straits Point will also approach Minor by Tuesday morning. A
gradual uptick in northwesterly winds should lower tidal
anomalies throughout the day on Tuesday.
