.SYNOPSIS...
In the wake of our Friday system, much quieter weather is
expected on Saturday, before more winds develop on Saturday
night into Sunday. Gusty channeled flow from south winds,
locally up to 40 mph will be possible tonight as a clipper
system rides north of the border. Mountain snow chances will
continue through the weekend as a parade of quick moving system
traverse the region through early next week. Seasonable to just
above average temperatures and continued snow chances are likely
heading into the holiday travel period.

.NEAR TERM /THROUGH SUNDAY/...
As of 139 AM EST Saturday...
*A Wind Advisory remains in effect for portions of northern New
 York and areas east of the Green Mountains spine until 7 AM
 for gusts up to 45 to 50 MPH and additional isolated power
 outages.

An arctic boundary continues to slide to the southeast across
northern and central Vermont with some enhanced areas of snow.
The band has begun to weaken, but behind, much cooler air is
advecting in with west northwest flow. While BTV current sits at
30, Plattsburgh is at 26 and Massena at 21 as of 1 AM. As the
boundary continues southeastward early this morning, shallow
moisture will be dragged along with it as brief ridging builds
in for today. Most areas should see some sun this morning before
clouds return this afternoon. Winds will also weaken to near
calm by midday with a wind shift to the south taking place over
the course of the day. Temperatures remain on the cool side in
the 20s for most of the day before southerly winds and waa kicks
in with temperatures reaching their highs Saturday evening, and
will continue to increase into Saturday night.

A clipper system will ride north of the border, with a trend
that has taken the system further north, resulting in stronger
waa. Temperatures by Saturday evening should reach back to
freezing and perhaps into the mid 30s for the Champlain and St.
Lawrence Valleys overnight. These warmer temperatures will be
ushered in by a strong 60-70 kt jet at 5000ft agl. Given the
northerly trend of the center of the low well north of the
international border, precipitation chances have lowered with
mainly just chances near the international border and in the
Adirondacks. While precipitation should start as snow for most
areas Saturday evening, rain will mix in across the St. Lawrence
Valley overnight. With the center of the low to the north,
chances of impacts from the associated cold front will increase.
The NAM soundings suggest the presence of about 100-150 J/kg of
CAPE associated with the boundary over northern New York with
decent convergence along a thin area of frontogenesis. By Sunday
morning there is a increased chance of some heavier bands of
showers, with embedded snow squalls possible which could impact
travel Sunday morning, particularly in the St. Lawrence Valley.
Concurrently ahead of this boundary will be a weak lake effect
band off Lake Ontario. While the flow regime will be favorable
for banding across southern St. Lawrence County, temperature
profiles will limit snow, and will likely be more rain under the
band into Sunday morning with temperatures in the low to mid
30s.

With precipitation chances lowered, more mixing will take place
with channeled flow in the wider valleys as the surface warms,
but 850mb temperatures undergo caa leading up to sunrise Sunday
morning. HREF probabilities suggest an 80% chance of seeing >40
mph gusts at BTV Saturday night. Also concerning is that there
is good agreement in 40kt winds at 1000ft on GFS/NAM/HRRR
soundings, which would not take much forcing to mix these winds
to the surface. Consequently, have increased gusts, especially
in the CPV Saturday night up to 30 to 35 mph, with future
updates likely to increase further if trends continue.
Temperatures will continue to be on the rise Saturday night into
Sunday morning following a non-diurnal curve with little
typical overnight cooling taking place. Temperatures by Sunday
morning will be about 10 degrees warmer than the same time this
morning.

.SHORT TERM /SUNDAY NIGHT THROUGH MONDAY/...
As of 139 AM EST Saturday...A cold front will slowly pass
through the region Sunday morning from west to east. The band
will lose most of the forcing associated with it as the parent
system lifts north further away from the area, drawing most of
the energy and moisture with it. Main concerns will be continued
gusty winds during the day Sunday across the northern
Adirondacks and Champlain Valley with gusts 25 to 35 mph. Lake
effect showers will wain with the passage of the boundary
shifting winds and the axis of the band south of the region.
Temperatures will fall back to single digits and low teens
Sunday night with good caa. Wind chills will be near 0 to the
negative single digits with gusts continuing. While moisture
will be limited, northwest flow with orographic lift should keep
some slight to chance PoPs across the western facing slopes of
the northern Adirondacks and northern Greens Sunday night into
the day Monday. Snow ratios will be 15-20:1 with any snow that
falls on the more light and fluffy consistency. A few inches of
snow is possible close to Jay Peak and in the Adirondacks.
Temperatures will be relatively seasonable in the low to mid 20s
with weaker winds Monday.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
As of 139 AM EST Saturday...A clipper system approaching from
the central Great Lakes region will bring the potential for
light snowfall across northern NY and VT, likely starting during
the pre- dawn hours Tuesday across northern NY, with stratiform
snow overspreading the remainder of Vermont through mid-
morning. There is a low chance of a rain/snow mix during Tuesday
afternoon as boundary layer temperatures warm into the 33-36F
range in the immediate Champlain Valley and the St. Lawrence
Valley. That said, snow should be the predominant precipitation
type, with some minor travel impacts due to snow covered
roadways expected throughout Tuesday. Based on present
indications, a 2-4" snowfall is generally expected, with the
bulk of that falling during the daylight hours on Tuesday.

Once the clipper system translates to our east, sfc high pressure
will briefly crest over the North Country for Christmas Eve Day.
Generally dry conditions expected with seasonable high temperatures
in the mid-upper 20s, except lower 30s for the valleys of s-central
Vermont. Once the sfc ridge axis shifts to our east, breezy S-SW low-
level flow will redevelop across our region for Christmas Day. This
will allow temperatures to warm into the 35-40F range for Christmas
afternoon. Modest low-level warm advection may be sufficient to
result in some light rain/snow showers on Christmas, but overall
forcing appears weak at the present time. Indicated 30-50% PoPs for
rain or snow showers, and slightly higher (60%) across the higher
summits. Above normal temperatures will continue into Friday with
highs near 40F in most locations.

.AVIATION /07Z SATURDAY THROUGH WEDNESDAY/...
Through 12Z Sunday...A cold front will bring periods of snow
shower activity (1-3sm vsby) for a brief time between 06-09Z
this morning with minimum snow accumulations expected (generally
a coating to 0.5"). Temperatures will be dropping below
freezing with the frontal passage, which may result in icy spots
for airport ground operations across the region. Diminishing
clouds expected through the daylight period with VFR conditions
returning to all TAF locations by 12Z Saturday. Surface winds
will be quite changeable across VT and northern NY during the
next 24 hours. Seeing W winds generally 10- 20kts and gusts up
to 30kts thru the pre-dawn hours Saturday. Winds briefly shift
into the NW and N during Saturday morning. Winds shift back into
the S-SW quickly late Saturday afternoon and evening, with at
BTV, expecting south winds 15-20kts with gusts to 30kts starting
around 00Z Sunday. Will also be monitoring for LLWS areawide
during the 00-12Z Sunday period as gradient flow becomes
moderately strong.

Outlook...

Sunday: VFR. Chance SN, Chance SHSN.
Sunday Night: Mainly VFR, with local MVFR possible. NO SIG WX.
Monday: VFR. NO SIG WX.
Monday Night: Mainly VFR, with local MVFR possible. Chance SHSN.

.MARINE...
A Lake Wind Advisory continues tonight for gusty west winds of
15 to 25 knots with localized gusts 25 to 30 knots possible.
Waves will be 2 to 5 feet on the board lake. Winds quickly
decrease toward sunrise on Saturday, before increasing again on
Saturday night.

.EQUIPMENT...
NOAA Weather Radio station WXM-44, transmitting from Mt.
Ascutney, Vermont, on frequency 162.475 MHz is non-operational
at this time. NWS technicians have diagnosed the problem, but
repairs will likely not be able to occur for quite some time due
to circumstances beyond our control. Therefore, the time of
return to service is currently unknown. The following NOAA
Weather Radio transmitters may be able to provide service during
this outage: WWG 50 from Burke Mtn, VT at 162.425 MHz and WNG
546 from Hanover, NH at 162.525 MHz.

Equipment malfunctions at the Colchester Reef meteorological
station will likely leave it inoperable for an extended period
of time. This site is not serviced by the NWS. Technicians do
not currently have an estimated return to service for this
station. Use extra caution when navigating the broad waters of
Lake Champlain, and please contact us if you observe winds
significantly deviating from the forecast.
