.DISCUSSION...

KEY MESSAGE 1...Chance for patchy freezing drizzle this evening
over Downeast into the Central Highlands with minor icing on
elevated roadways.

KEY MESSAGE 1 DESCRIPTION...
Weak occlusion will bring light snow showers to the north this
evening. Low level moisture remains over the Bangor Region and
Downeast into central areas while moisture dries out aloft leaving
potential for freezing drizzle and/or snizzle in these areas. Most
likely timeframe for this will be between 02-06z this evening before
moisture evacuates the entire column. This may create icy roads and
walking surfaces tonight.

KEY MESSAGE 2... Snow showers possible Friday night through
Saturday night, which could potentially impact travel.

KEY MESSAGE 2 DESCRIPTION...
Occluding low pressure system approaches from the west Friday
night, bringing periods of snow showers into the region. Models
are struggling with the exact location of the triple point low
set up. The GFS continues to predict a faster and stronger low
system. The general trend for precipitation is that it moves in
from the SW Friday night, and gradually moves eastward. The QPF
values are relatively low with this system, so generally only
anticipating a few inches of snowfall. There is favorable
vorticity and omega values, with the highest moisture content
along Downeast region. Some travel disruptions possible, but
with current trends, not anticipating significant implications.

KEY MESSAGE 3...Potential for snow Sunday into Monday, which
could cause hazardous travel conditions.

KEY MESSAGE 3 DESCRIPTION...
This upcoming weekend, low pressure system approaches from the
southwest, and potentially tracks along the Gulf of Maine.
Still plenty of model uncertainty however, which is important
because the track of these coastal low systems heavily
influences snow totals throughout the region. GFS is currently
showing a very strong low pressure system tracking north and
moving through the waters just east of Nova Scotia, with a very
tight pressure gradient. The ECMWF, however, has a much further
south in the Atlantic track, which is ultimately much weaker,
and has much less snowfall entering the region. Overall, GFS and
Canadian models seem to be trending north and stronger. If this
trend continues, there could could be decent travel
disruptions, predominantly Downeast. Continue to monitor the
forecast for updates.

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
VFR cigs initially will drop to MVFR later this afternoon at
Aroostook terminals.  FVE, CAR and PQI may experience IFR snow
showers between 23z-07z tonight before improvement to MVFR/VFR
by morning.

Downeast terminals have the possibility of experience MVFR
conditions in -fzdz between 02 and 08z tonight though this is a low
probability and have only included potential as a PROB30. Rapid
improvement to VFR after 03z this morning.

VFR conditions expected through Wednesday night all terminals.

NW winds expected Wednesday afternoon with potential for gusts
between 15-20kts. NW winds will become light Wednesday evening.

Thursday - Friday...Mainly VFR. NW wind, becoming NE on Friday,
at 5-15 kts.

Friday night - Saturday night...Low confidence. Most likely
VFR/MVFR in the north. Downeast could be IFR in snow if the
system tracks north, or could be MVFR if the system misses to
the south. N/NE winds at 5-10 kts.

Sunday...Generally VFR, as snow begins to move in from the S.
N/NE winds at 5-10 kts.

&&

.MARINE...Seas will approach 5ft over the outer reaches of the
outers waters late this evening into Wednesday morning. Winds will
approach 20kts from the NW Wednesday morning into the afternoon
hours. Winds will once again approach SCA levels Thursday morning
over the outer waters but the near term portion should remain
headline-free.

Potential for low-end Small Craft conditions over all
waters early Thursday. Seas and winds go below Small Craft
criteria Thursday evening, until Friday night, when Small Craft
conditions are expected again. There is a chance for Gales
Sunday into Monday. Light freezing spray possible early
Thursday, and Saturday. Chance for snow on Friday night to
Saturday, and Sunday into Monday. Winds from the NW Thursday,
shifting to the NE by Friday.
