.WHAT HAS CHANGED...
As of 548 PM EDT Friday...
Have cancelled the winter weather advisory as accumulating snow
has moved out of the area. Some patchy drizzle or freezing
drizzle is expected overnight as low levels remain saturated.
&&
.KEY MESSAGES...
As of 349 PM EDT Friday...
1. Snow, heavy at times, will continue into the evening hours
with deteriorating road conditions.
2. Another clipper low will bring additional chances for snow
on Sunday into Sunday night.
3. While significant weather is unlikely, wintry conditions
will continue Tuesday through Friday. Greatest chances for
widespread winter precipitation with travel impacts is currently
on Thursday.

.DISCUSSION...
As of 349 PM EDT Friday...
KEY MESSAGE 1: Clipper system and associated fronts pushing
across our area this afternoon is bringing snow, sometimes
heavy, to the area. This system has deep moisture, heavy QPF and
high precipitation rates which has led to some quick
accumulations of wet snow. Have bumped snowfall totals back up
today as we observe heavy snow on radar, webcams and
observations. Snow came in quickly and will also exit quickly
after about 00-03z.
KEY MESSAGE 2: Another clipper low will cross just south of our
area on Sunday. Similar scenario to today with wet snow
expected and will be heavy at times. This time the low will
cross central and southern Vermont. Shifts north or south with
this storm track will change precipitation type. At this time
looks like our storm total QPF will be around two tenths of an
inch along the international border up to three quarters of an
inch across southern Vermont. Snow will move into our area from
the west early Sunday morning, and will be heavy at times
through the morning hours. With the low track right across our
southern zones, we could see some mixed precipitation and rain
creeping northwards. The highest snow fall totals will be from
the northern Adirondacks eastward across the central Greens and
then east to the Connecticut river valley, 3 to 6 inches of snow
with higher totals in the higher elevations. 1 to 2 inches of
snow are expected along the international border, and across
southern Vermont.
KEY MESSAGE 3: Below normal temperatures will persist next week
with temperatures a bit above freezing during the daytime and
below freezing at night. Two periods of light snow accumulations
are noted, primarily Tuesday night into Wednesday, and Thursday
afternoon into early Friday. That being said, predictability in
timing through a fast northwest flow pattern is fairly low, so
stay tuned for details as we get closer. There is greatest
uncertainty on Thursday. One, less likely scenario suggests a
brief warmup and mainly rain ahead of a cold front. This idea is
dominated by the GEFS, with only some contribution from the
GEPS and little ENS. However, the consensus idea would suggest
the large scale ridge out in the western US will maintain cooler
air and more of a clipper- type system for that event with
primarily snow, or at least elevationally-dependent snow.

.AVIATION /00Z SATURDAY THROUGH WEDNESDAY/...
Through 00Z Sunday...Primary aviation concern overnight is areas
of drizzle/freezing drizzle, along with low visibilities and
ceilings. Currently a combination of LIFR/IFR conditions prevail
with mist/drizzle or freezing drizzle based on temps hovering
near 32F. Strong subsidence inversion is helping to lower
ceiling heights with LIFR/IFR expected at most sites overnight,
except improving conditions with northwest downslope flow at PBG
and MSS. Eventually drier air slowly develops across our taf
sites with CIGS improving to MVFR/VFR by morning. Also, areas of
fog/mist will continue to produce IFR/LIFR visibilities thru 06z
before conditions slowly improve toward sunrise. Winds are light
from the northwest 3 to 6 knots, except northeast at 10 knots at
MSS. VFR conditions are expected at all sites after 15z
Saturday and continue into Saturday afternoon with northwest
winds 5 to 10 knots.
Outlook...
Saturday Night: Mainly VFR, with local IFR possible. Definite SN.
Sunday: Mainly MVFR, with areas IFR possible. Definite SN,
Definite RA, Definite FZRA.
Sunday Night: Mainly MVFR, with local IFR possible. Chance SHSN,
Chance FZRA.
Monday: Mainly VFR, with local MVFR possible. Chance SHSN.
Monday Night: VFR. Slight chance SN.
Tuesday: VFR. NO SIG WX.
Tuesday Night: Mainly VFR, with local MVFR possible. Chance SN.
Wednesday: Mainly VFR, with areas MVFR possible. Chance SN.
