.KEY MESSAGES...

.DISCUSSION...
As of 153 AM EST Saturday...

.KEY MESSAGE 1: Weak low pressure continues to bring snow across
northern New York and Vermont this morning; this will persist
through the afternoon. CAMs continue to increase QPF associated
with this system as models trend for a longer/deeper duration of
moisture training over the region, especially southern Vermont.
This has resulted an increase in forecast snowfall across the
southern Adirondacks to near the Mohawk Valley through south-
central New Hampshire and prompted expansion of Winter Weather
Advisories through this region. Totals of 2-6 inches are
expected.

.KEY MESSAGE 2: Low pressure passing northwest of the St
Lawrence Valley will sharply tighten the pressure gradient
across northern New York Monday as SFC-850mb flow goes
unidirectional off of Lake Ontario. Models currently support
surface gusts 30-40 mph in the St Lawrence Valley and around 30
mph for the northern Champlain Valley. Deep mixing is present in
model soundings with a 5kft+ depth of saturation. Coupled with
modest CAPE and a passing trough, there could be a few squalls
in northern New York as bursts of lake enhanced snow showers
move through. These gusts could support periods of blowing snow
resulting in an extended period of poor visibility for portions
of northern New York while allowing for lighter snow showers to
penetrate into northern Vermont.

.KEY MESSAGE 3: Cool temperatures and unsettled weather will be the
main story for next week, with several chances for precipitation
possible. Guidance supports an impressive period of lake effect snow
early next week, primarily to our south, but some higher snow
accumulations will be possible across St. Lawrence County and
portions of the Adirondacks and the band waffles northward.
Unseasonably cold temperatures will be possible this week,
especially on Tuesday where daytime highs will only be in the single
digits and teens with overnight lows dropping into the single digits
above and below zero. Additional chances for showers will be
possible as the week progress, with some guidance suggesting the
potential for another weak system on Thursday, although it`s still a
bit far out for details.

.AVIATION /12Z SATURDAY THROUGH WEDNESDAY/...
Through 12Z Sunday...VFR conditions, with some occasional MVFR,
currently prevail across terminals this morning as the region
currently sits in a lull between the expected snow showers.
which should increase in coverage over the next few hours,
especially across southern terminals. As the morning progresses,
more widespread and prevailing MVFR conditions are expected to
develop due to both ceilings and some visibilities. IFR
visibilities are possible within any snow, with the period of
heaviest snow arriving towards 15 or so, with KRUT expected to
see the worst flight conditions. Snow will continue for most of
the afternoon, beginning to taper off towards 21Z or so
depending on the terminal. Ceilings should gradually improve
towards the end of the forecast period, with VFR conditions
possible at several terminals. Winds will generally be south to
southwesterly through the afternoon, with occasional gusts up to
20 knots.

Sunday: Mainly VFR, with local MVFR possible. Slight chance SHSN.
Sunday Night: Mainly VFR, with local MVFR possible. NO SIG WX.

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.

The Colchester Reef meteorological station is out of service.
This site is not serviced by the NWS and there isn`t an
estimated return to service at present. Use extra caution when
