The local office's own words before this wind chill warning 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 wind chill warning went out at Feb 1, 3:04 PM EST, 43 minutes earlier.

Area forecast discussion, Feb 1, 3:04 PM EST, 43 minutes before
Area Forecast Discussion
National Weather Service Buffalo NY
304 PM EST Wed Feb 1 2023

.SYNOPSIS...
Lake effect snow will continue east of the lakes today with the
heaviest snows focused on the Tug Hill Plateau. The lake snows will
drift north and weaken tonight. The coldest air mass of the season
will arrive with an arctic front Thursday night into Saturday with
bitterly cold temperatures and dangerously low wind chill values.
The extreme cold will be relatively short-lived, with temperatures
moderating by the end of the weekend, and trending back above
seasonal normals for next week.

&&

.NEAR TERM /THROUGH THURSDAY/...
Regional radar shows lake effect snow east of Lake Erie and Lake
Ontario this afternoon. An intense lake effect snow band extends
from Lake Ontario near Ellisburg to northern Lewis county this
afternoon. This organized band is showing 35-45dbz off of ktyx. A
research group reported 2.6"/hour in the band. Snowfall rates of 2-
3"/hour rates is likely through the afternoon. A Lake Effect Snow
Warning is in effect for Jefferson, Oswego, and Lewis counties
through tonight. Off Lake Erie, lake effect snow is disorganized and
weaker and will continue mainly south of Buffalo through the
afternoon.

A large area of high pressure resides over the Ohio Valley today.
Cold, westerly flow will continue across the eastern Great Lakes
with 850mb temperatures down to -16C over the relatively warm lakes.
A shortwave trough is moving east across the northern tier of the
Great Lakes region this afternoon. Synoptic moisture is present
across the eastern Great Lakes especially across Lake Ontario. The
combination of cold, nicely aligned westerly flow and synotpic
moisture has resulted in lake effect snow east of both lakes.

Off Lake Ontario... Westerly flow along the long axis of the lake
and an increase in upstream moisture has led to an intense band of
lake effect snow. Forecast soundings east of Lake Ontario show
equilibrium levels around 5k feet however saturation is entirely
through the dentritic growth zone. Snowfall rates will average 2-3
"/hour through the remainder of the afternoon in the center of the
band. Looking upstream, there is an evident wind shift on satellite
and radar which will move the lake effect snow band south into
southern Jefferson, western Lewis and far northern Oswego counties
late this afternoon into this evening. Winds will become southwest
later tonight and it will weaken and direct the lake effect band
northward mainly after midnight. This will bring the band back into
the City of Watertown Thursday morning. Lake effect snow will
diminish Thursday morning across Jefferson county. Additional
snowfall accumulations of 5 to 10 inches are expected in the lake
effect band with the highest amounts across south-central Jefferson,
western Lewis, and far northern Oswego counties.

Off Lake Erie, disorganized and weakening lake effect is ongoing
mainly south of Buffalo this afternoon. Cold, westerly flow is
across the shorter fetch of the lake with greater synoptic moisture
to the north. Snow showers with visibility 3-5 miles and a dusting
is likely with these showers into early evening. The westerly flow
will back to the southwest tonight and direct the snow showers north
and into Buffalo and the Northtowns. While warm air advection takes
place, an uptick in snow showers is possible as flow becomes more
aligned with the long axis of the lake. Moisture will be lacking
with forecast equilibrium levels near 3k feet. A dusting to an inch
is possible before lake snow ends by Thursday morning.

Low temperatures will fall to the teens to low 20s tonight.
Southwest flow increases Thursday as a strong cold front approaches
from the upper Great Lakes. Winds will increase with gusts up to 40
mph northeast of the Lakes through the afternoon. Snow showers will
begin to enter the far northern reaches of the forecast area by
Thursday afternoon. High temperatures will reach the upper 20s to
low 30s.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY NIGHT/...
...Bitter Cold by the End of the Work Week...

A full phasing of the longwave pattern leading into this period will
result in a deep trough that will be centered over the eastern half
of North America. The notorious polar vortex will be displaced to
the south in the process, being found in the vicinity of Hudson Bay
and Quebec for the bulk of this period. That means that the coldest
air in the northern hemisphere will be just to our north (H85 -40C /
H925 -36C). Coldest air so far this season, with some gusty winds as
well just to make sure we really feel the 'bite' of this frigid
airmass. The details...

A strong arctic cold front will charge southwards across our
forecast area Thursday evening. The frontal passage will be
accompanied by a burst of moderately heavy snow/blowing snow as
winds gusts up to 35-40 mph with most areas picking up a quick inch
or so of snow. However, localized amounts upwards of a few inches
will be possible across the higher terrain east of the Lakes. If the
associated convection is significant enough, it could lead to snow
squall warnings, especially if it were to impact the I-90/I-87
corridors and/or occur earlier in the evening (i.e. during rush
hour). At this time, appears North Country (I-81 corridor) would
have the best chance of seeing the quick burst of heavier snow that
could impact the tail end of the rush hour.

Winds quickly veer around to the northwest in the wake of the
frontal passage, allowing broad multi-banded lake snows to set up
south/southeast of both Lakes overnight. Temperatures that will be
in the upper 20s to lower 30s early Thursday evening ahead of this
front, will then plunge into the single digits away from the Lakes
(below zero North Country) by daybreak, with below zero wind chills
area wide and well below zero wind chill readings already impacting
the North Country.

Cold advection will continue Friday, as the base of the digging
longwave trough crosses the lower Great Lakes. H85 temps will drop
to as low as -28C over the bulk of the region (sub -30C east of Lake
Ontario) during the course of the day with near surface temps
holding near steady within a few degrees of their overnight lows.
This will translate into daytime highs that will range from single
digits below zero across the North Country, to just the mid single
digits to very low teens across the lake plains and across the
Genesee valley/Finger Lakes region. A northwest wind gusting to 30-
35 mph at times will combine with these frigid temps to generate
dangerously low wind chills that will average 10 to 15 below across
the western counties and 20 to 30 below east of Lake Ontario.
Meanwhile, a cyclonic flow of arctic air crossing the generally open
waters of Lake Ontario will continue to support some light snow to
the tune of an inch or two, with similar amounts southeast of Lake
Erie over the Chautauqua Ridge. Given the bitter cold, this will be
a greasy snowfall featuring plates rather than fluffy dendrites.

Friday night will then guarantee to be the coldest period in recent
memory, as all areas away from the immediate lake shores will easily
drop below zero. Sites east of Lake Ontario will likely experience
mins of 20 to 25 below. While the axis of an arctic high will drift
across the region during the second half of the night, there will be
enough of a gradient to easily generate wind chill values ranging
from the minus teens and lower 20s across the western counties, to
as low as -45 in the vicinity of the Tug Hill/western Dacks.

The confidence is now 'maxed out' for sites east of Lake Ontario for
extreme wind chills...so have UPGRADED the wind chill watch to a
warning. This headline runs from 06z Fri through 18z on Saturday.
While high confidence is in place for wind chill advisories over the
western counties for roughly the same time frame...that type of
headline is not appropriate from this 'distance' from the event.
This headline will be issued in a later forecast package. Will
continue to highlight this in social media and in the HWO product.

While the bitter cold will be slow to loosen its grip on our
forecast area Saturday morning, the core of the coldest air aloft
will have already exited across Quebec and the Labrador Sea. As the
aforementioned surface high moves across New England Saturday
afternoon though, the door will be open for warm advection to
increase over our forecast area. This will bring a screeching halt
to any leftover light snow and will allow the temps over the western
counties to modify into the upper teens and lower 20s by the end of
the day. Sites east of Lake Ontario will make it into the teens,
however readings over the Tug Hill and western Dacks will struggle
to climb out of the single digits.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
A weak positively tilted mid-level trough across the upper Great
Lakes Sunday morning will sweep southeast across the central and
lower Great Lakes Sunday and Sunday night. This trough will support
a weak surface low over southern Ontario, Canada Sunday morning,
where as this low pulls east, its attendant cold front will sweep
from west to east across the region late Sunday and Sunday night.
Due to the quick and efficient warming ahead of the system the night
prior and during the day on Sunday, precipitation will be a mix of
rain and snow. There will be a better chance for precipitation east
of both lakes due to some lake enhancement.

The aforementioned trough axis will finish crossing and push east of
the region Monday. In its wake, mid-level ridging will push across
the Great Lakes and support surface high pressure to cross overhead
of the area. This will cause any lingering showers to peter out by
Monday morning and then support a rather dry day and night.
Additionally in the wake of the cold front Monday, some chillier air
will have filtered across the region causing temperatures to drop,
though daily highs will remain a few degrees above normal.

The next northern stream mid-level trough will push east across
southern Canada Monday night through Tuesday, pushing its trough
axis across the area late Tuesday and Tuesday night. This being
said, the upper level feature will support a surface low to push
across southern Canada and drag its attendant cold front across the
region Tuesday into Wednesday. Long term guidance now has a few
discrepancies between timing and location of the low pressure track
and therefore better timing of precipitation is hard to pin point
down this far out. However, temperatures at this time will have
warmed up into the 40s by the middle of next week and therefore
mostly rain is expected.

&&

.AVIATION /20Z WEDNESDAY THROUGH MONDAY/...
Lake effect snow continues east of Lake Erie and Lake Ontario this
afternoon. VFR conditions exist between the snow bands. The more
intense band is east of Lake Ontario, in particular across the
southern half of KART. The band will slowly move south today before
coming back north tonight. MVFR/VFR expected at KART into this
evening before IFR/LIFR conditions expected as the snow band returns
tonight. Snow will end northeast of Lake Ontario Thursday morning.
Off Lake Erie, disorganized lake effect snow will move north through
tonight. Mainly MVFR conditions expected east of Lake Erie and will
move into KBUF tonight before ending by Thursday morning.

Outlook...

Thursday afternoon...Mainly VFR.
Friday...Blustery with MVFR/IFR in lake effect snow showers
southeast of the lakes.
Saturday...Mainly VFR.
Sunday...MVFR/VFR in rain and snow showers.
Monday...VFR.

&&

.MARINE...
Southwest winds will freshen today as a low pressure system
passes to our north, with SCA criteria winds and waves on both
lakes. Small Craft Advisories then remain in effect through late
Friday night. A strong cold front will move across the lakes late
Thursday afternoon through Thursday evening. Winds will increase
ahead and behind the front. Gales are possible on the open water of
Lake Ontario during this time. Small Craft Advisories are likely
with northwest winds Thursday night through Friday night.

With the abnormally cold conditions, some freezing spray will be
possible Friday.
