Area Forecast Discussion
National Weather Service Buffalo NY
1253 AM EST Fri Jan 22 2021

.SYNOPSIS...
Lake effect snow will continue overnight east of Lakes Erie and
Ontario, with the heaviest snow falling across the higher terrain
east of Lake Ontario through midday Friday. Northwest winds will
then carry lake effect snow to the southeast of Lakes Erie and
Ontario late Friday through Saturday, with spotty light to moderate
accumulations expected. High pressure will build into the eastern
Great lakes by Sunday morning, ending the lake effect snow.

&&

.NEAR TERM /THROUGH TODAY/...
Regional radar showing the Lake Ontario band shifting southward
across the Tug Hill region shortly after midnight. This band will
produce moderate to heavy snow through daybreak, while meandering
slightly southward. Snowfall rates of 1-2 inches per hour can be
expected.

An area of snow showers has organized across the higher terrain east
of Lake Erie, partially from lake moisture and partially from
synoptic scale forcing from a passing mid level shortwave. These
snow showers will be briefly heavy as they move from the western
Southern Tier towards the western Finger Lakes, but will not last
long and will only produce an inch or so accumulation through the
early overnight.

Temps aloft gradually get colder overnight, as the flow becomes more
westerly and eventually northwesterly late. The addition of the
cooler air aloft (-9C at 850mb) will support a lake response off of
both lakes with better, more focused band off of Lake Ontario, due
to the stronger low-level convergence across the Tug Hill, and much
deeper synoptic scale moisture and support from a passing shortwave.
Forecast soundings show sufficient moisture and lake equilibrium
levels to around 8kft for Lake Erie and 13kft for Lake Ontario.
Strongest, most focused lake effect will be east of Lake Ontario
while more transient lake effect will occur east of Lake Erie.

Total snow amounts tonight through the first half of Friday east of
Lake Ontario over the Tug Hill may reach 15-20 inches, with snowfall
rates of 2-3 inches per hour late this evening through Friday
morning. The higher amounts will be confined to the Tug Hill, with 5-
9 inches expected across the surrounding lower elevations with 1-2
inch per hour snowfall rates. Amounts will be much lower east of
Lake Erie given the lower inversion heights and less synoptic scale
moisture and support. Expect 2-4 inches on the hills from tonight
through Friday.

Arctic front currently dropping across Lake Superior arrives over
western NY Friday morning. Once the arctic front moves through on
Friday morning, lake effect bands on westerly flow will shift south
along the southern shore of Lake Ontario by early afternoon, and
western Southern Tier and really a spray of snow showers with lower
vsby at times/possible snow squalls could develop across rest of the
area as well as H85 temps fall to around -15c by Friday evening. The
mobile nature of the lake bands off of both lakes with the passing
front will limit snowfall amounts for any one location. However, one
thing that continues to show up in the high res guidance is
potential for dominant streamer band originating off the wide open
waters of eastern Lake Superior and crossing Lake Huron as well. In
general, snow amounts of 1-3 inches will be possible for Friday
afternoon with the lake bands southeast of the lakes.

A northwest flow regime continues Friday night. The best activity
continues to look to set up off Lake Ontario. Mesoscale model
guidance is not in particularly good agreement on where a Georgian
Bay connection will set up, but pattern recognition suggests this is
most likely across Wayne and northern Cayuga counties initially
during the first half of the night, possibly drifting southwest
towards Rochester late Friday night. If this upstream connection is
able to remain in one place long enough advisory criteria snow
amounts are possible southeast of Lake Ontario Friday night through
Saturday morning. In Rochester the greater snow amounts would likely
focus along Route 104 and into the eastern suburbs.

&&

.SHORT TERM /TONIGHT THROUGH SUNDAY NIGHT/...
Main upper level trough axis will cross the area by midday Saturday,
with a cold, gusty northwest flow continuing to produce lake snows
southeast of both Lakes through Saturday morning. Some additional
minor accumulations will be possible before drier air and subsidence
associated with ridging surface and aloft builds across the area
from the west Saturday afternoon in the wake of the trough axis
passage. That said, would still expect some light lake effect
snow showers to continue southeast of the lakes into Saturday
evening.

Outside of a few lingering light snow showers southeast of the Lakes
during the first half of Saturday night, high pressure will keep dry
weather around for Saturday night and Sunday. Some moisture will try
to move into western NY Sunday night, however it appears conditions
will remain dry.

Otherwise, expect a cold weekend with below normal temperatures.
Highs Saturday will range mainly through the teens, with some low
20s across the lake plains. It will be a bit warmer on Sunday with
generally 20s found south of Lake Ontario and teens hanging on east
of Lake Ontario. Saturday night lows will range from the upper
single digits to mid teens south of Lake Ontario, to possibly below
zero across the North Country.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
An approaching mid level trough and associated surface cyclone will
bring steadily increasing chances for snow showers for Monday. There
is still uncertainty concerning the track of a low pressure system
Monday night and Tuesday as latest 12z model guidance continues to
diverge. The 12z ECMWF is the furthest north with this system,
overspreading most of the area with precip, while the latest GFS
keeps it just to the south of our area. The Canadian NH continues to
alternate between a more southerly or more northerly track, with the
latest 12z run now indicating the latter but still keeping much of
the North Country dry. Forecast uses a blend of model guidance with
a chance of snow from this system, the higher chances for snow being
over the Southern Tier. Added some slightly higher PoPs south of
Lake Ontario for Monday afternoon as marginal 850mb temperatures and
northeast flow may lead to some lake enhancement. Whether this comes
to fruition or not will depend on the track of the low and how far
north its warm frontal boundary is able to push.

Precip chances for the area will gradually decrease overnight Monday
through Tuesday as the low continues moving east. Colder air
filtering in on a NNW flow and marginal 850mb temps may lead to a
few light lake effect showers south of Lake Ontario Tuesday night
and Wednesday. A shortwave trough then approaches the area Wednesday
night, which looks to potentially impact the area for Thursday.

Highs through the period will average in the mid to upper 20s for
most of the area, with lows in the mid to upper teens and single
digits east of Lake Ontario.

&&

.AVIATION /06Z FRIDAY THROUGH TUESDAY/...
Lake effect snow is intensifying east of Lake Ontario late this
evening, mainly just south and east of KART. Heavy lake effect snow
will bring VLIFR conditions to the Tug Hill region tonight through
Friday morning. The majority of this will miss KART, although a few
brief periods of IFR are possible through the first half of tonight
in passing snow showers. The snow will be lighter east of Lake Erie,
with snow showers and occasional MVFR/IFR from later this evening
through Friday morning.

Boundary layer flow will veer to the northwest later Friday
afternoon behind a cold front. This will move lake effect snow to
the southeast of Lakes Erie and Ontario and spread snow showers and
bands of snow into a broader area, with less intensity in general.
Expect areas of IFR southeast of the lakes Friday afternoon through
Friday evening. Some of this will impact KROC by mid to late
afternoon and continue into Friday evening.

Outside of lake effect areas, expect mainly VFR VSBY with areas of
MVFR CIGS tonight through Friday. A few spotty passing snow showers
from Lake Huron may bring local/brief IFR.

Outlook...

Friday Night and Saturday...Lake effect snow showers likely
southeast of the lakes with IFR conditions. Scattered snow showers
with MVFR elsewhere.
Sunday...Generally VFR.
Monday...Mainly VFR.
Tuesday...A chance of snow and associated IFR.

&&

.MARINE...
Moderate to strong west winds shift to the northwest on Friday.
Small Craft Advisories continue through Friday for the prolonged
period of stronger winds. Small craft advisory conditions will
likely last into Friday night and Saturday along the south shore of
Lakes Erie and Ontario even after the winds become northwest. High
pressure will build into the eastern Great Lakes Sunday, allowing
winds to subside.
