Synopsis
Surface high pressure will move eastward tonight, allowing for
mainly cloudy skies tonight with scattered snow showers across
the adirondacks and northern green mountains. Friday will be
milder with increasing south to southwest winds. Highs Friday
will generally be in the low to mid 40s. A low pressure system
passing to our north on Saturday will bring a trailing cold
front across the north country allowing for periods of rain or
snow showers Saturday into Saturday night. Overall, temperatures
will be trending above seasonal levels over the next 5 to 7
days.

Near term through Friday night
As of 1007 pm est Thursday... Starting to get some light snow
off of lake ontario and a weak shortwave moving across southern
quebec province. Should last a few more hours before flow
becomes more northwest and precipitation tapers off. Going
forecast has this covered well and no changes needed at this
time.

Previous discussion...

relatively quiet weather through Friday night. Chilly air mass
in place thanksgiving afternoon in association with sfc ridge
axis extending from central pa newd across ny and northern new
england. Highs generally reaching the upr 20s to lower 30s this
aftn... Roughly 10deg below seasonal averages for late november.

Meanwhile, a weak 700-500mb shortwave trough is moving ewd
across sern ontario and NRN ny, and this feature is bringing
widespread mid-level clouds across our region despite the sfc
ridge.

This evening, it continues to appear that some lake effect snow
showers will develop off of lake ontario as sfc ridge slides ewd
and deep-layer SW flow develops. This is reflected especially in
nam-3km and btv-4kmwrf forecasts showing a brief period of lake
effect snow 00-06z across the route 3 corridor from star lake
wwd across SRN st. Lawrence county. Maintained a period of
likely snow showers, with possible snow accumulations around 1"
across SRN franklin ny and st. Lawrence counties. May also see a
few flurries ewd across the champlain valley and especially into
the jay peak area overnight with trajectories favoring enewd
advection of the lake moisture mainly 06-12z tonight. Low
temperatures won't be as cold as last night, generally in the
mid-upr 20s with abundant cloud cover and above mentioned light
snow shower or flurry activity.

On Friday, strengthening p-gradient will bring breezy
conditions, with s-sw winds 10-20 mph, with a few gusts to 30
mph in vicinity of lake champlain. Expecting a good moderation
in temperatures, with Friday's highs generally in the low-mid
40s. Should also see mostly sunny conditions.

South winds continue Friday night as next shortwave trough moves
ewd into the great lakes region. Shouldn't see much direct
impact from that system and attendant cold front until the
daylight hrs Saturday, but the south flow will keep our temps
mainly in the low 30s for overnight lows, except upr 20s across
the NRN adirondacks and mid-upr 20s for ERN vt where some of the
deeper valleys may decouple with stable pbl conditions.

Short term Saturday through Saturday night
As of 245 pm est Thursday... Models remains consistent in
showing a shortwave trough and attendant cold front approaching
the area during the day on Saturday, then passing east and south
by Saturday night. Have largely maintained persistence in
showing increased chances of rain showers through the day as
skies trend mainly cloudy. Highest coverage should occur across
the northern mountains, especially in the adirondacks as
southwest boundary layer flow transports lake moisture
downstream. Overall QPF will remain light however, and generally
less than a tenth of an inch. Temperatures to remain mild -
mainly 40s under modestly gusty south southwest flow. Rain
showers then transition to snow showers from north to south and
higher to lower elevations over time Saturday night while waning
in overall coverage as cold front exits east and synoptic flow
trends northwesterly. Some minor accumulations of a dusting to 2
inches will be possible by sunrise Sunday, mainly across the
northern mountains. Lows near seasonable late november norms
from the mid 20s to lower 30s.

Long term Sunday through Thursday
As of 245 pm est Thursday... Much of next week will continue to
favor a progressive synoptic flow pattern across the northern
tier of the nation with several weak shortwave features bringing
periodic light rain snow shower chances interspersed by brief
interludes of high pressure and quiet weather. Any threat of
arctic air will remain bottled well north of our area with near
seasonable temperatures expected under an average airmass of
eastern north pacific and southern canadian origin. This is in
contrast to what the moderately negative ao and nao indices
would typically predict (i.E. Much colder). The best threat of
additional light precipitation will occur Sunday into Sunday
evening, and again by next Wednesday with passage of
aforementioned shortwave energy. Again any precipitation or snow
accumulations will be light. High temperatures to range through
the 30s during Sunday Monday and in the upper 30s to mid 40s
from Tuesday onward. Lows mainly in the upper teens to mid 20s
Sunday night Monday night, moderating into the 25 to 35 range on
average thereafter.

Aviation 03z Friday through Tuesday
Through 00z Saturday... WidespreadVFR and MVFR ceilings are
expected through 12z before areal coverage of clouds decreases
through the remainder of the period andVFR conditions prevail.

A lake effect snow band is expected to develop off the eastern
tip of lake ontario and move up into our area later
tonight... Mainly across northern new york. Kslk will likely be
the only sight impacted with ifr conditions due to snow and
lower clouds. This will last through about 10z before coming to
an end. Winds will increase from the south after 12z with gusts
up to 20 knots across much of the area.

Outlook...

Friday night:VFR. Slight chance shra.

Saturday: mainlyVFR, with areas MVFR possible. Chance shra.

Saturday night: mainly MVFR, with local ifr possible. Chance
shra, chance shsn.

Sunday: mainly MVFR, with areasVFR possible. Chance shsn, slight
