Synopsis
Snow showers will continue to linger across the north country
tonight... Especially in the mountains. However... Any
accumulations will be minor. Winds will remain gusty from the
northwest. Relatively dry weather is expected on Monday... But
temperatures will be below normal. Southerly flow quickly
develops on Tuesday and sunshine... Dry weather... And high
temperatures in the 40s to around 50 returns to the area.

Near term through Monday
As of 414 pm est Sunday... Quick update based on surface
observations showing a bit more snow now across parts of
northern new york. Have increased precipitation chances over
this area for the next few hours before tapering off.

Previous discussion...

surface low and cold front are now north and east of the area
this afternoon. Low level cold air advection continues with west
to northwest flow with temperatures holding steady in the mid
20s to lower 30s in northern new york and in the mid 20s to mid
30s across vermont. Thus any precipitation will be in the form
of snow showers. In terms of precipitation... The vertical depth
of moisture has decreased making for any precipitation to be on
the light side. Webcams show this to be the case as well. In
addition... West to northwest low level flow is helping to focus
some of the precipitation in the mountains. Of note is the the
increasing froude numbers along the west slopes of the green
mountains which suggests any upslope precipitation will be
carried more downstream on the east side of the greens.

However... Any additional snow amounts tonight will generally be
an inch or less. Should still see quite a bit of cloud cover
tonight with lows getting down into the mid teens to the mid
20s.

On Monday... We remain in west to northwest flow in the morning
with the flow gradually backing to the west throughout the day.

This may allow some lake effect moisture to our south to lift up
into our area... But may only affect parts of the northern
adirondacks and the southern half of vermont. Below normal
temperatures continue with highs generally in the mid 20s to mid
30s.

Short term Monday night through Tuesday night
As of 324 pm est Sunday... Flow continues to back to the
southwest through the period. Any lake effect moisture Monday
night would lift north but tends to dry out so only have some
slight chance mention over northern new york. With the flow
aloft becoming more southwest warm air advection should take
place and can see temperatures rising overnight. Have made the
low earlier in the night with rising temperatures overnight. The
warm air advection continues on Tuesday with a good deal of
sunshine... Dry weather... And highs getting back into the 40s to
around 50. Upper trough appears to be moving slower and thus the
first half of Tuesday night will remain dry before
precipitation moves in after midnight.

Long term Wednesday through Sunday
As of 324 pm est Sunday... Primarily a very broad cyclonic flow
pattern for the period with very minor disturbances and slight
roller coaster of temperatures but largely below normal. There
is still an outside threat of a coastal storm wed-wed ngt but
most current indications are keeping this a mid-atlantic and
this far enough away with no impacts for our area but still
worth monitoring for the next few days.

Wednesday: cold front exiting region with lingering snow showers
thru mid-late morning then gradual improvement for holiday travel.

Temperatures pretty much holding steady or falling slightly during
the day with highs in the 30s 40.

Thanksgiving: quiet with surface high in control but the eventual
approach of another northern stream shortwave by Thursday night.

Currently dry with temperatures in the 30s.

Thursday night Friday: much of the energy with northern stream
shortwave is in canada but can't rule out some isold sct snow
showers, especially in the mountains. Lows in the 20s and highs in
the 30s.

Friday night-Sunday: we start off dry Friday evening with surface
high and some shortwave ridging but that quickly gives way to next
upstream system. Another shortwave and surface reflection moving
north of great lakes and international border with some decent warm-
air advection ahead of it for light snow snow showers toward
Saturday morning then main energy shifts ne, however trof axis
remains across region with several replenishing shortwaves moving
through into Monday. Therefore it will be generally unstable, cold
with snow showers.

Aviation 21z Sunday through Friday
Through 18z Monday... Mix ofVFR MVFR as low pressure has lifted
northeast and sharp cold front has passed area as of 17z sun.

Mountain snow showers will bring about MVFR to possible ifr in
cigs vsby thru 20-21z then improvement toVFR. It will be windy
from west at 13-20kts with gusts 23-32kts through 00z Monday
then backing off slightly to 10-15kts g20-25 kts thru 18z mon.

Vfr tonight and Monday with gradual decreasing cloudiness
through the remainder of the period.

Outlook...

Monday night:VFR. No sig wx.

Tuesday:VFR. No sig wx.

Tuesday night: mainlyVFR, with local MVFR possible. Chance shra,
chance shsn.

Wednesday: mainlyVFR, with areas MVFR possible. Chance shsn,
slight chance shra.

Wednesday night: mainly MVFR, with areasVFR possible. No sig wx.

Thanksgiving day: mainlyVFR, with areas MVFR possible. No sig
wx.

Thursday night: mainlyVFR, with areas MVFR possible. Chance
shsn.

Friday: mainlyVFR, with areas MVFR possible. No sig wx.

Marine
As of 1125 am est Sunday... A lake wind advisory remains in
effect for today. Winds have turned to the northwest and are in
the 25 to 35 knot range with gusts approaching 40 knots. This
will create significant wave heights in the 2 to 5 foot range
with a moderate chop. These conditions may prove hazardous to
those operating small craft, especially on the eastern half of
the broad lake and in vermont bays inlets with westerly
exposures. Gusty northwest winds will abate slightly later this
evening into Monday.

Btv watches warnings advisories
Vt... None.

Ny... None.
