Area Forecast Discussion
National Weather Service Baltimore MD/Washington DC
928 PM EST Fri Jan 22 2021

.SYNOPSIS...
High pressure will gradually build over the region tonight
through Sunday morning, then move offshore Sunday night. Low
pressure will pass through the area Tuesday. High pressure will
return for Wednesday and the second half of next week.

&&

.NEAR TERM /THROUGH SATURDAY/...
Colder temperatures but dry conditions will evolve throughout
the weekend. Gusty winds Saturday will make it feel much colder
than the actual temperatures. High pressure will be in control
through the period. Highs Saturday will only reach the 30s in
many places. A brisk northwest wind will make it feel like
temperatures are in the teens and 20s. A few snow showers will
be possible across the mountains, but these will be of little
significance.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/...
Still chilly Saturday night with temperatures in the 20s or
middle teens in the west. Less wind Sunday with high pressure in
control and temperatures remaining chilly with high temperatures
in the middle to upper 30s. Thickening clouds Sun night as
moisture increases ahead of low pressure over the central
Plains. Any precip through 12Z Mon should remain well west of
I-81 and in the form of snow with any accumulations less than an
inch.

&&

.LONG TERM /MONDAY THROUGH FRIDAY/...
High pressure off to our southeast will continue to slide further
offshore early Monday as low pressure emerges out of the south-
central US. Guidance has come into better agreement over the last 24
hours in regards to the track of the system. Given a negative EPO,
PNA, and NAO, the pattern is more inducive of a inside tracking
system (northeastward along the Appalachians) which is now being
modeled by all guidance members. The question now becomes the timing
of the system which will help determine p-types. As of now, precip
onset looks to occur Monday morning and continue into the
evening/overnight hours.

Overall, guidance has been trending downward in terms of snow
accumulations and continues to trend more towards a wintry mix type
of event, especially at onset until a more southerly flow at the
surface scours out any cold air trapped in the BL. With a good
amount of uncertainty still remaining, it appears that (at this time)
areas best suited for any winter weather will be along the Mason
Dixon Line and into western Maryland and the eastern Panhandle of
WV.

Tuesday appears to be more of a transition day, as showers are
likely to continue throughout much of the day; albeit the bulk of
the precip will have ended. Canadian high pressure returns for
Wednesday, resulting in dry conditions. Another low pressure system
may impact the region Thursday into Friday. However, the trend
is for the system to remain more towards our south. However,
confidence this far out remains low and will have to continue to
monitor forecast trends over the next several days. General
temperature trend in the long term period looks to remain
slightly below normal for this time of year.

&&

.AVIATION /03Z SATURDAY THROUGH WEDNESDAY/...
Blustery conditions Sat with a brisk northwest wind and gusting
to 30 to 35 mph. Winds will diminish Sunday with increasing
clouds Sun night with any precip likely to hold off until after
12Z Monday.

CIG/VSBY restrictions are likely, especially by Monday afternoon as
low pressure spreads northward across the terminals. Restrictions
are likely to continue through Tuesday as the low slowly exits the
region. However there's a good chance that conditions improve late
Tuesday into Wednesday.

&&

.MARINE...
Strong SCA conditions Saturday into Saturday night with winds
diminishing Sun afternoon.

SCA will be possible Monday and
Tuesday as low pressure spreads eastward across the waters.
SubSCA conditions possible on Wednesday.

&&

.LWX WATCHES/WARNINGS/ADVISORIES...
DC...None.
MD...None.
VA...None.
WV...None.
MARINE...Small Craft Advisory until 6 AM EST Sunday for ANZ530>534-
     537>543.
     Small Craft Advisory until 8 PM EST Saturday for ANZ535.
