Synopsis
High pressure will begin to build in from the west late tonight
and Tuesday. Low pressure will approach from the west on
Wednesday... Shifting into southern quebec by late in the day. A
trailing cold front will push in from the west Wednesday night
and will stall just off the coast by Thursday morning. Low
pressure will track northeast along this boundary Thursday and
into the maritimes by Thursday evening spreading precipitation
across the area. Colder air returns behind the cold front
Thursday night.

Near term until 6 am Tuesday morning
1045 pm update... Upper level low continues to move east of the
region late this evening and any light snow will come to and end
around midnight. No major changes to the forecast this evening,
bitterly cold wind chill values will continue overnight.

840 pm update... Little change to the going forecast on this
frigid night. Wind gusts are gradually decreasing, but wind
chill values are expected to remain dangerously cold overnight.

Light intermittent snow will come to an end in the next couple
of hours across maine.

5 pm update... Upper low moving overhead at this time. Enough low
level moisture is in place to allow for snow growth (since it's
so cold, the snow growth region is not too far above the sfc).

There may also be some seeder-feeder processes going on as well.

This is all resulting in some intermittent light snow across the
region as the upper low traverses the region. Have included this
wording in the forecast along with higher pops for the next 2-3
hours. Little or no accumulation is expected. Otherwise,
bitterly cold continues.

Previously...

upper level low crosses the CWA this afternoon and swinging a
weak wave south along the east of it. This will not only help a
surge of stronger winds and colder air into the cwa, but is
setting off a few light snow showers and flurries across the
cwa. Once this swings thru, winds should pick up with gusts in
the 20-30 mph range thru the evening, and may subside a bit
after midnight. This combined with the very cold air will
produce wind chill of -25 to -35 in the mountains, and in the
15 to 25 below range most everywhere else. So, if you are
headed out this evening, protect your skin and wear layers. Once
the wave moves through, we will start to see clearing,
especially after midnight. Actual min temps will range from -10
to -15 in the mtns, to zero to -10 in the south.

Short term 6 am Tuesday morning through 6 pm Tuesday
Should see NW winds persisting, but at lighter levels tue
morning, and may begin to weaken during the afternoon as the sfc
high pushes over the cwa. It will be sunny, and temps will
begin to warm aloft as well, so highs will rebound to 10-15 in
the north and in the low to mid 20s in the south.

Should see some early decoupling Tue evening, as just some
cirrus moves in late tue, and winds will go light. So early rad
cooling will drop lows to around zero in the mtns, and to around
10 above in the south, probably around midnight. However
increasing SW flow and thickening clouds will stop the temps
from falling, and in the ERN zones and mtns valleys they will
likely not move much for the rest of the night, while in SRN nh
and along the me coast they may start to creep up after
midnight.

Long term Tuesday night through Monday
Upper level trough pushing onshore in the west coast today will
track across the mountains and into the plains. It will then set
up shop across the central us for quite some time as a ridge of
high pressure to the west of it sends reinforcing waves
southward out of canada. Meanwhile to the east we will have a
bit more variable weather further downstream from the developing
block. Initially a ridge builds in ahead of the remnants of the
trough moving onshore in the west. This spreads warm air into
the region just as this wave approaches. But once this wave
moves through we will find ourselves under the influence of the
broad eastern trough with multiple rounds of cold air dropping
into the trough and keeping the chill around. By the beginning
of next week there are signs of some buckling of the trough over
the east coast and models differ wildly on where to track the
wave riding around the edge of the trough and possibly toward
new england.

The aforementioned wave entering the west coast today will be
tracking through the great lakes on Wednesday. Some light snow
showers could precede its arrival on Wednesday, mainly in the
north. It will be warmer with temperatures warming above
freezing for the southern half of the area. As the parent low
tracks eastward across southern quebec, the frontal zone
arrives on the east coast Thursday morning. As it does so,
secondary low pressure likely forms and pushes north along the
front. This will help to spread more widespread precipitation
into northern new england. By this time, however, the
temperature will have warmed above freezing for a good part of
the area, so this may well be a rain event for most of us.

However, cold air could be a bit slow to exit at ground level,
and the cold ground could itself be enough to cause some
freezing rain even as the temperature warms. For the most part,
though, this should be light snow changing to rain before ending
on Thursday.

The cold front crosses the area late Thursday and brings a
return to colder weather. The air immediately behind the front
is not that cold, though, so we will still be right around
normal or a few degrees above normal on Friday. Another surge of
even colder air arrives Friday night bringing below normal
temperatures Saturday.

As mentioned earlier, models vary wildly on how to handle the
upper waves late this weekend and into next week. Cold trough
over hudson bay could sling an embedded trough axis toward our
area on Sunday with some light snow and moderating temperatures.

But as the southern stream trough is reinforced over the
rockies and southern plains, it could send a wave northeast
along the east coast in the Monday Tuesday time period with more
significant precipitation possible.

Aviation 04z Tuesday through Saturday
Short term... Some periods of MVFR will be possible in blowing
snow light snow thru this evening, and khie could see ifr in
shsn into the evening. NW winds will continue to gust to 25 kts
thru the evening, but should begin to subside a bit after
midnight. OtherwiseVFR can be expected Tue and Tue night.

Long term... Conditions becoming MVFR on Wednesday and ifr
Wednesday night into Thursday as precipitation moves in. This
will mostly be rain for the area, but some snow will be possible
at the onset as well as some pockets of freezing rain inland. A
clearing cold front brings all this to an end Thursday evening
withVFR conditions returning except for lingering MVFR ceilings
in the mountains through Friday.

Marine
Short term...

gales and moderate freezing spray will continue overnight into
tue morning, but temps will warm and winds diminish tue
afternoon, so this should help limit the freezing spray, but
may see SCA conditions into Tue evening.

Long term... Expect southwest winds on Wednesday shifting to west
behind a cold front Thursday evening. Both ahead of and behind
the front winds will likely reach advisory levels, possibly low
end gales. We may finally see a period of more calm conditions
by Saturday.
