.DISCUSSION...
KEY MESSAGE 1...

Scattered lake effect snow showers will continue this afternoon as
flow becomes more westerly and snow showers gradually drift north of
the region overnight. Multiple bands will remain present through at
least the afternoon and possibly into the evening. Then tonight
there will be one main band off of Lake Ontario that will set up
around the NYS Thruway Corridor before lifting north by Wednesday
morning. This band will continue to impact the counties within the
Winter Storm Warning with additional 5 to 8 inches of snowfall
possible. That will likely push some overall totals with this event
to over 2 feet. In addition, a Lake Erie band will develop tonight
and extend into NY`s Southern Tier. Additional snowfall
accumulations will be possible in Steuben County tonight and then in
the Finger Lakes region as the band lifts north Wednesday. No
changes were made to the current winter headlines.

Despite slightly calmer winds compared to this morning, winds remain
quite gusty. The Wind Advisory remains in effect for the entire
region as observations have shown gusts occasionally between 45 and
50 mph. These stronger winds will lead to blowing and drifting snow,
especially in open areas. Winds will remain breezy overnight but
gradually become calmer. The Wind Advisory remains in effect until
7pm this evening. As a result of these stronger winds, wind chills
will stay in the single digits for most of the area today and
tonight.

KEY MESSAGE 2...

Following the lake effect snow late Wednesday, a frontal system will
drop into the region and bring a round of light snow across the
region. Snowfall accumulations will be 1 to 4 inches but could be
locally higher. With this update, the highest amounts are expected
in the higher elevations of Cortland, Onondaga, and S. Cayuga
Counties with totals around advisory criteria but it was decided to
hold off on any advisories given the borderline amounts. There will
be some instability, steep lapse rates, and gusty winds that could
lead to scattered snow squalls NYE night. This could impact travel
for those out celebrating the beginning of the new year.

Behind the front, northwesterly flow will advect in colder air
leading to the coldest day of the forecast period and lake effect
snow redeveloping by Thursday morning. Many of the same areas in CNY
that were impacted by this early week set up will see additional
snowfall once again, though accumulations will be light. Flow will
become more southwesterly by Friday morning, so any organized bands
that do develop are expected to drift north of the region.

KEY MESSAGE 3...

Cold air mass remains locked in place over our region Friday onwards
with broad upper level trough over the northeast. Below average
temperatures are expected with 850 mb temperatures averaging -15
through the weekend. West to northwest flow continues with a few
short waves passing through. This will produce lake effect snow
showers with some enhancement with the passing waves. While it is
too early to pinpoint exact snowfall totals, additional snowfall
accumulations will be possible. Surface temperatures will range in
the 20s during the day with lows in the teens overnight. Some drier
air moves into the region Sunday though some light lake effect snow
may linger into Sunday. Winds appear to shift southwest briefly on
Monday as a short wave approaches the region from the west. This
brings an additional chance of snow showers.

&&

.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
Lake effect snow showers will continue through most of the
period especially over north central NY terminals. Lake effect
showers over SYR/RME will contain LIFR vis with falling and
blowing snow through the early morning hours at SYR and mid-
morning at RME. Narrow lake effect bands over ITH/ELM/BGM will
cause MVFR restrictions with brief IFR vis possible. Confidence
is highest at BGM and ITH this evening. AVP remains too far
away from the lakes to experience any major restrictions.

A brief break in the lake effect snow is possible later
Wednesday morning and early afternoon as winds shift
southwesterly. A new area of light snow then moves into the area
later Wednesday afternoon and evening, with potential squalls
for the evening hours. These snow showers and squalls will bring
renewed MVFR and occasional IFR vsbys to most taf sites.

Outlook...

Wednesday night...Periods of snow likely with IFR restrictions
expected (moderate to high confidence)

Thursday through Sunday...Restrictions possible as lake effect
snow showers are expected to continue.
