What forecasters said that day

The local office's own words before this winter storm 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 winter storm warning went out at Jan 17, 12:58 PM EST, 40 minutes earlier.

Area forecast discussion, Jan 17, 12:58 PM EST, 40 minutes before
Area Forecast Discussion
National Weather Service Buffalo NY
1258 PM EST Fri Jan 17 2020

.SYNOPSIS...
Lake effect snow showers will slowly tapering off through the
afternoon. Clearing skies through the day today before increasing
clouds from west to east tonight ahead of the next storm. The
next area of low pressure causes a mixture of snow, sleet and
rain for Saturday, before a transition to lake effect on Sunday.
Cooling temperatures from Sunday through the middle of next
week will bring daytime highs below normal.

&&

.NEAR TERM /THROUGH TONIGHT/...
Multiple bands of light lake effect snow are very persistent south
of Lake Ontario early this afternoon, but are now showing signs of
weakening. Boundary layer flow has become almost due north, crossing
the short axis of Lake Ontario. Despite the short fetch, a favorable
mixed phase layer resides beneath the relatively shallow inversion,
allowing lake effect snow to persist. The best snow will fall from
the rochester area east to near Fulton, and also south into the
western Finger Lakes. These areas may see another dusting through
mid afternoon. All of this will come to an end by mid to late
afternoon as inversion heights lower further, and high pressure
builds directly over the eastern Great Lakes, disrupting low level
flow. Lake effect clouds will hold through early afternoon, then
should break up by mid to late afternoon with some sunshine
developing.

Unfortunately though, the sun later this afternoon will be
misleading and daytime high temperatures will only be in the upper
teens to near 20 south of Lake Ontario and in the upper single
digits to low teens east of Lake Ontario. These expected
temperatures today will be the coldest of the season for some areas.

Tonight, mostly clear skies to start the evening will begin to
increase in cloud coverage from west to east through the night as an
area of low pressure approaches the Great Lakes and its warm front
approaches the area through the night. By daybreak light snow will
be near the far western portion of the area with likely POPs making
it into Chautauqua County a little before sunrise. Early low
temperatures will be in the single digits to low teens south of Lake
Ontario and in the -5 to -10 degree range east of Lake Ontario.
Temperatures will slowly warm through the night as warm air
advection increases across the area.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
Potentially significant snow accumulations east of Lake Ontario
during this period. Winter Storm Watch has been issued for this
area. Moderate accumulating lake effect snow is also expected
Saturday night into Sunday east of Lake Erie.

A relatively strong, amplified shortwave with a 500 mb jet maximum
exceeding 100 kts is expected to move east into the mid-Mississippi
Valley by Saturday morning. The associated cyclone will follow the
strongest warm air advection and vorticity advection provided by the
shortwave aloft, and will likely be deepening and moving through the
Great Lakes Saturday afternoon, reaching southern Ontario by Saturday
evening.

Models remain in pretty close consensus showing deep warm
advection will continue to expand into the area during the day
Saturday leading to widespread precipitation. The leading edge
of this precipitation should already be into far western New
York Saturday morning and should expand quickly eastward and
cover the entire area by late morning. Resident column plenty
cold enough for precipitation to start everywhere as a period of
snow. Track of the surface low to our north and west across the
central Great lakes will force a strong warm nose into western
New York by mid day or early afternoon. The resulting rapid
warming column will likely bring the potential for a mix of
sleet, possibly some freezing rain and then eventually mixing
with or change to rain. The best chances to see a complete
change over to all rain will be on the lake plains of western
New York during the afternoon and early evening. Some of this
change over could also occur across the Genesee Valley.
Precipitation should remain all snow east of the Finger Lakes.
The incoming warm air aloft will result in snow ratios lower
than climatology, around 8:1 and closer to 4:1 in areas where
the precipitation type becomes mixed. Snowfall amounts during
the day Saturday tricky due to changeable thermal profile
throughout the day, but overall looking at a 2-4 inch
accumulation, with amounts closer or even less than 2 inches in
areas where mixed precipitation occurs and especially those
areas where rain mixes in. The colder areas east of the Finger
Lakes should be closer to 4 inches, with even perhaps a bit more
across the higher terrain of the Tug Hill.

The synoptic/warm air advection part of this event should wrap up
for the most part by Saturday evening and the lake response portion
of the event will commence. Strengthening westerly winds on the
backside of the low lifting into Ontario will send colder air
into the region. The bulk of the snow will be confined to
favored westerly upslope areas east of the lakes with several
inches of accumulation likely, especially late Saturday night
as more organized snow bands develop. The heaviest snow likely
will be across the Tug Hill region where westerly flow upslope
will be maximized. Tightening gradient south of the departing
low will result in a period of strong winds within a well mixed
environment with wind gusts of 35 to 45 mph common with some
potential for even stronger winds along lake shore areas.

On Sunday, the majority of the focus for snowfall will evolve
into orographic and lake enhancement. Steady cold advection
through the day will yield increasing lake instability, with
lake induced equilibrium levels rising to around 10K feet. The
increasing lake instability will work cooperatively with
increasing westerly upslope flow east of the lakes.

The deepest synoptic scale moisture and best overall setup will be
east of Lake Ontario, with westerly flow targeting the Tug Hill
where significant additional accumulations will be possible on
the Tug Hill through the day, and moderate accumulations for
surrounding lower elevations. East of Lake Erie, synoptic scale
moisture is not quite as deep, but should still be supportive of
at least moderate accumulations across higher terrain. Outside
of the lake enhanced areas, only expect an inch or two at most
on Sunday.

It will remain windy on Sunday with momentum transfer profiles
suggesting wind gust of 30-40 mph with some potential for even
stronger winds early in the day.

Sunday night a secondary cold front will cross the eastern Great
Lakes, with some additional moisture and convergence. This will
produce fairly widespread snow showers across most of the region.
Westerly flow will veer northwesterly with the passage of the
trough, taking lake effect/upslope snows east of the lakes and
spreading them out to the southeast of the lakes. This will increase
the areal coverage of lake effect snow, but also decrease the
intensity as boundary layer winds end their alignment with the long
axis of the lakes. Expect additional light to moderate accumulations
overnight.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
Northwest flow and an additional trough passage Monday and Monday
night will continue to support fairly widespread lake effect snow
showers southeast of the lakes with some additional accumulations
likely. Northwest flow lake effect snow showers will continue
through Tuesday as a very cold airmass crosses the eastern Great
Lakes. Expect several days of highs in the teens to low 20s and lows
in the teens to single numbers (below zero east of Lake Ontario)
from Tuesday through Wednesday. Lake effect snow showers will
finally shut down by Wednesday night as the coldest air aloft moves
away, and surface high pressure builds over the eastern Great Lakes.

Later next week the cold air will steadily retreat back into Canada,
with temperatures warming back closer to average Thursday with
mainly dry weather. Looking a little farther ahead, it appears the
cold/wintry pattern will relax at least temporarily, with all
operational model guidance supporting a return to above normal
temperatures again by Friday and Saturday of next week.

&&

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
Currently, light lake effect snows are continuing southeast of the
lakes. This is causing all of the TAF sites to remain in broken MVFR
conditions, except for ART where clear skies prevail. Lake effect
snows off of Lake Ontario are causing areas of IFR VSBY including
KROC. Conditions should improve across the area to VFR as the lake
effect snows dwindle down throughout the afternoon.

Throughout the night tonight conditions should remain VFR even
though increasing cloud cover is expected as the next system
approaches. Conditions will start to deteriorate to MVFR and IFR
conditions on Saturday as snow and possibly wintry mix enter the
area from west to east.

Outlook...

Sunday through Tuesday...MVFR/IFR due to lake effect snows and
blowing snow east of the lakes.
Wednesday...MVFR improving to VFR as lake effect snows peter out.

&&

.MARINE...
Northerly winds will continue to weaken through the rest of today as
high pressure builds directly over the eastern Great Lakes.
Approaching low pressure will increase southerly flow on Saturday,
but as a trailing cold front passes Saturday night, westerly gales
are becoming increasingly possible. Gale watches are currently in
effect for both Lake Erie and Lake Ontario.

&&

.TIDES/COASTAL FLOODING...
Strong winds developing Saturday night into Sunday may bring
another round of lakeshore flooding to Lake Ontario.

The combination of high lake levels, strong onshore westerly
winds, and high waves may produce some lakeshore flooding in
bays and inlets at the east end of Lake Ontario impacting
lakeshore areas of Jefferson and Oswego counties.
