.SYNOPSIS...
A breezy, upslope pattern will continue throughout the weekend,
supporting several inches of wet mountain snow through the weekend
in the northern Greens and blustery conditions. Additional
precipitation will return as mainly rain Monday night into Tuesday,
with more uncertain chances towards late week.

&&

.NEAR TERM /THROUGH SUNDAY/...
As of 346 PM EST Saturday...Surface low pressure centered over the
Canadian Maritimes will continue to bring unsettled weather to the
region this weekend as we remain under cyclonic flow. Throughout the
afternoon, precipitation has decreased in areal coverage and has
become more terrain focused. A shortwave will pass through the region
tonight, reinvigorating shower chances this evening, especially in
the favored upslope areas. Temperatures tonight will be seasonable,
in the 20s and 30s. The strong pressure gradient will allow for
gusty winds to continue throughout the night, especially on Lake
Champlain.

Tomorrow the region will continue to be under northwest flow and a
strong pressure gradient, continuing to bring upslope showers and
blustery conditions. Precipitation will largely be limited to the
northern Greens tomorrow, with strong westerly flow, so locations
like Jay Peak should see several inches of snowfall. Temperatures
tomorrow will be on the cool side, with highs in the 30sw to low
40s, but with strong winds it would feel more like 30s, and even the
teens across the higher terrain. By Sunday night showers will begin
to wind down as a brief period of surface high pressure begins to
build into the region. Overnight lows will generally be in the mid
to upper 20s, with some cooler spots across the Adirondacks.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH MONDAY/...
As of 346 PM EST Saturday...Monday will be characterized by partly
cloudy skies increasing to cloudy through the day with high
temperatures ranging from the mid/upper 30s (coldest in northeastern
Vermont) to low mid 40s(warmest in southern Vermont). Breezes will
be light with high pressure cresting and beginning to exit.
Overnight, temperatures should cool initially with northeastern
Vermont radiating more efficiently due to less cloud cover than the
rest of the North Country. This cooling will have implications as a
system moves into the Great Lakes region with a frontal boundary
pushing into the region. Sub-freezing surface temperatures in the
Adirondacks and northeastern Vermont combined with a warming profile
aloft will promote a period of freezing rain before profiles warm
enough to allow enough sensible heat transfer to warm surface
temperatures above freezing. Up to a tenth of an inch of ice is
possible overnight, but more could occur in northeastern Vermont
should a northerly cold wedge form replenishing cold air. Elsewhere,
rain is expected with some snow possible for highest peaks.

&&

.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
As of 346 PM EST Saturday...The system continues to push through
Tuesday with surface temperatures rising to preclude freezing rain.
Total QPF looks to range 0.2-0.5", so not as much as recent
rainfall, but enough to continue to provide beneficial wetting of
soils. A breezy northwesterly flow pattern develops behind the front
resulting in cooling late Tuesday and continue upslope precipitation
chances. Could see snow levels drop to near Lake Champlain level
Tuesday night with a transition to snow for most elevations. QPF
will be lower, so accumulating snow chances will be highest for
higher elevations with little expected below 1000ft given wet
surface conditions.

The region is favored to remain under the influence of the upper low
with winds promoting some lake enhanced showers off of Lake Ontario
Wednesday into Thursday. Most of these showers will stay south of
the Adirondacks, but could see some extending eastward into portions
of the southern Adirondacks. Elsewhere, the upslope pattern will
weaken by Wednesday night as relative high pressure moves through.
More certain will be cooler temperatures with highs generally in the
30s and lows in the 20s. The next system is favored to approach
towards the end of the week. However, models are split on the
surface track lending to uncertainty in the system`s character.
Consensus favors a southerly track keeping the North Country on the
colder side Friday with potential for snow while some single runs
show a westward track with potential for rain, snow, and mixed
precipitation. Either way, this system could impact post holiday
travel plans.

.AVIATION /21Z SATURDAY THROUGH THURSDAY/...
Through 12Z Sunday...A mix of MVFR and IFR conditions across all
terminals this afternoon, with some light rain and snow showers
moving through and continuing for the next several hours. MVFR
conditions are expected to prevail at most terminals through the
forecast period, with localized IFR conditions at KEFK and KSLK
where they are more likely to see snow. Some improvement to VFR
ceilings will be possible at some of the lower terminals,
especially KPBG but there may be enough lingering moisture to
keep ceilings below 3000 ft AGL.

Winds are currently north-northwesterly and breezy, with gusts
of 20 to 25 knots at several sites. Winds will trend more
westerly, first across northern New York then tonight over
Vermont. There is the potential for some LLWS after 00Z,
particularly at KRUT and KMPV with strong flow aloft.

Outlook...

Sunday Night: VFR. NO SIG WX.
Monday: VFR. NO SIG WX.
Monday Night: VFR. Chance SHRA, Chance SHSN.
Tuesday: Mainly MVFR, with local IFR possible. Definite SHRA.
Tuesday Night: Mainly MVFR, with local VFR possible. Chance SHSN,
Chance SHRA.
Wednesday: Mainly MVFR, with areas VFR possible. Chance SHRA,
Chance SHSN.
Wednesday Night: Mainly MVFR, with areas VFR possible. Slight
chance SHSN.
Thanksgiving Day: Mainly VFR, with areas MVFR possible. Slight
chance SHSN.

.MARINE...
Very favorable northerly channeled flow has developed,
resulting in winds in excess of 25 knots along with gusts
exceeding 30 knots on the broad lake. Expect peak winds will
decrease along with wave heights just a bit by afternoon as
shallow inversion weakens during the day but steady winds near
25 knots will persist. Additional strong winds on the lake will
develop tonight into tomorrow as winds become more westerly.
Wave heights will be 2 to 4 feet for much of the next two days.
