What forecasters said that day

The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Buffalo, NY wrote its last area forecast discussion before this small craft advisory went out at Dec 29, 4:12 PM EST, 2 hours 44 minutes earlier.

Area forecast discussion, Dec 29, 4:12 PM EST, 2 hours 44 minutes before
Area Forecast Discussion
National Weather Service Buffalo NY
412 PM EST Tue Dec 29 2020

.SYNOPSIS...
High pressure will build into the eastern Great Lakes with dry
weather tonight. A warm front will move through the area Wednesday
morning with a chance of a few light snow showers. The warm front
will usher in warmer temperatures for Wednesday afternoon, with an
approaching cold front then bringing a period of rain showers late
Wednesday and Wednesday night, possibly ending as some wet snow.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
Lake effect clouds for much of the area, but now only flurries
remain of earlier lake effect activity southeast of Lake Ontario
and east of Lake Erie. High pressure will continue to build in
as the pressure gradient relaxes to allow for considerably more
clearing and less gusty conditions this evening. This will be
short-lived, however, as the next system to affect the area will
already we advancing to the upper Great Lakes by that juncture.
This will allow for high clouds to encroach, which will
restrict drastic temperature falls over western New York
overnight. The later arrival of high clouds over the North
Country will allow readings to drop quite a bit more there.

Warm frontal segment traverses the Lower Lakes Wednesday morning.
Pretty good saturation looks to be present for a short window along
the warm front as it crosses the area Wednesday morning which should
allow for a band of light snow to develop. Warm advection with the
front will start to work warmer air aloft in, however, and this
could lead to a brief period of freezing rain or sleet just as the
snow begins to taper off. Otherwise, breezy day on tap ahead of the
trailing cold front with southerly winds gusting up to 25 to 35 mph.
This will also aid in nudging highs into the low to mid 40s along
the Lake Plains. Colder air will be harder to displace from the
interim Southern Tier, however, as well as interior Lewis County. As
cold frontal showers start to encroach from the west, this may yield
a secondary threat of freezing rain if those temperatures hang back
enough in the aforementioned areas. The best bet would be for these
areas to have a cleaner transition from snow to rain, so no winter
weather advisories are planned for the time being.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/...
The cold front shifts through Wednesday night. With its
passage, west-northwest flow drops 850 hPa temperatures
enough to start to get a lake response. This is reflected well
in the Canadian, so the forecast was pushed largely toward that
guidance through Thursday. However, as large scale moisture departs,
lake effect will not have the gusto that it has had recently.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
Low pressure over the lower Mississippi Valley will return the cold
front as a warm front, which will slowly work its way across the
area on Friday. Some light snow may develop out ahead of the warm
front as it approaches from the south Friday morning. As the warmer
air aloft noses into the area, model soundings indicate a better
sustained shallow surface freezing layer on the higher terrain in
the Southern Tier and the Tug Hill Plateau. This may facilitate the
formation of freezing rain Friday afternoon for the Southern Tier
and later Friday evening for the Tug Hill, though there still
remains uncertainty with timing and duration this far out. The area
should see all rain by Friday evening, which will gradually taper
off through the day Saturday.

A Southern Stream shortwave trough trails behind the low pressure
system, passing to our south during the day Sunday. 12z model
guidance has hinted at this shortwave possibly phasing with a
northern stream longwave trough, which could nudge it far enough
north to bring another round of precip for the area. High pressure
builds in as this system passes to our southeast, bringing dry
weather through Tuesday.

&&

.AVIATION /21Z TUESDAY THROUGH SUNDAY/...
WNW flow will support lake effect clouds and just a few lingering
flurries east and southeast of the lakes early this evening. Dry
weather will mostly prevail though with VFR VSBY and CIGS.

Outlook...

Wednesday...Mainly VFR. A chance of light snow in the morning, then
a chance of rain showers later in the day. LLWS possible.
Wednesday night and Thursday morning...MVFR/IFR with
rain likely, possibly ending as wet snow. Improvement to VFR
Thursday afternoon. LLWS possible Wednesday night.
Friday...IFR/MVFR with rain likely. Possibly starting as a
wintry mix at onset. Saturday...MVFR with chance of snow.

&&

.MARINE...
Most small craft advisories have ended this afternoon as west-
northwest flow has diminished across the eastern lakes. Southerly
winds will rapidly increase Wednesday ahead of a cold front, likely
producing another round of Small Craft Advisory conditions for the
eastern Great Lakes, which will then last into Thursday.

&&

.BUF WATCHES/WARNINGS/ADVISORIES...
NY...None.
MARINE...Small Craft Advisory until 10 PM EST this evening for
