Synopsis...
a cold front will move through the north country overnight with
a chance of rain or snow showers. There will be a slight chance
for rain and snow showers on Wednesday, mainly over the high
elevations of the Adirondacks and Green Mountains. A ridge of
high pressure will build into the region on Thursday with mostly
sunny skies expected. A low pressure area moving east across
the Ohio Valley will bring mixed wintry precipitation to the
north country late Friday into Saturday.

&&

Near term /through Wednesday/...
as of 710 PM EDT Tuesday...patchy drizzle, isolated -rw, and low
ceilings persist across the north country this evening, with
temps at 23z mainly 36-41f. Main synoptic feature of note is
the relatively compact, vertically stacked low exiting east of
New Jersey. Main precipitation shield with this system will remain to
our south. However, as the low tracks ewd, will see increasing
north-northwest winds and low-level cold air advection overnight. Cooling thermal
profiles will allow for a rain/snow mix as we move toward 04z,
and some lingering snow showers after 06z. Despite the low-
level caa, continued cloud cover will help to keep temperatures
up overnight with lows mainly in the 30s, except in the 20s over
the higher elevations.

The region will be under cold advection on Wednesday. Expecting
a slight chance for some rain or snow showers on Wednesday,
mainly over the higher elevations of the Adirondacks and Green
Mountains.

Short term /Wednesday night through Thursday night/...
as of 400 PM EDT Tuesday...any residual rain or snow showers
should come to an end early Wednesday night. A ridge of high
pressure will build south from Canada late Wednesday night and
will remain over the region through Thursday night. Expecting
mostly sunny skies on Thursday. A warm front will approach the
region well after midnight Thursday night, so will have a chance
of snow light snow late Thursday night and approaching daybreak
on Friday.

&&

Long term /Friday through Tuesday/...
as of 345 PM EDT Tuesday...snow expected to spread from north
to south across the north country on Friday with warming
temperatures during the day in southerly flow changing snow to
mostly snow. Some enhancement of quantitative precipitation forecast on eastern slopes expected
with shadowing effects on leeward slopes and valleys. Heading
into Friday night/Saturday morning, warmer air aloft will result
in wintry mix starting over northern New York and spreading eastward
into the Champlain Valley in the middle of the night. Northeast
Kingdom has best chance of remaining snow through Saturday
morning. Winds shift out of the north on Saturday as the main
coastal low pulls east and northern stream shortwave that
provided lift for wintry mix will move out of the area with
generally drying conditions Saturday into Sunday. Northwest upslope
precip possible through Sunday before surface high pressure
becomes the dominant feature through Tuesday.

&&

Aviation /00z Wednesday through Sunday/...

the forecast area. This mix and a bouncing between lower
categorieswill continue throughout the overnight hours. Areas
of fog development possible tonight, with MVFR- IFR vsbys.
Generally expect all terminals to see improvement on Wednesday
back to VFR by the afternoon.

some gusts into the upper teens late Wednesday afternoon.
