Area Forecast Discussion
National Weather Service Buffalo NY
1040 PM EST Mon Dec 18 2023

.SYNOPSIS...
Strong low pressure pulls northeast into Quebec tonight. A potent
trough approaching from the west will cross the area tonight through
Tuesday morning, with rain changing to accumulating lake enhanced
snow as much colder air briefly moves into the region. Snow will end
from west to east Tuesday, with high pressure then bringing dry
weather Wednesday through the end of the work week.

&&

.NEAR TERM /THROUGH TUESDAY/...
Strong mid level trough and embedded closed mid level circulation
will cross the eastern Great Lakes tonight through Tuesday morning,
providing a period of organized ascent and deep moisture. Strong
cold advection arriving this evening into tonight, allowing for a
change to snow. The changeover to wet snow has already occurred
across the higher terrain of the western Southern Tier and the
changeover will be complete across western New York by midnight,
then head east across the Finger Lakes and the eastern Lake Ontario
region overnight.

Synoptic scale forcing and deep moisture will support a period of
widespread light snow crossing the area from west to east tonight
through the first part of Tuesday morning. Increasingly cold
northwest flow will allow for lake enhancement and upslope
enhancement to be superimposed on the synoptic scale environment,
supporting locally higher snowfall totals southeast of the Lakes.
Forecast soundings show a deep saturated dendritic growth zone
overnight through early Tuesday morning, supporting a transition to
higher snow:water ratios after a slushy start this evening.

The best juxtaposition of synoptic scale forcing, lake enhancement,
and upslope will focus along the Chautauqua Ridge, where local
accumulations of 8-12 inches are expected. Accumulations of 4-8
inches will surround this area from the Boston Hills to the ridges
of western Wyoming County to northern/western Cattaraugus County.
These totals are a little higher than previous forecast owed to
changeover from rain to snow occurring a bit earlier.

Lake Ontario lake enhancement will develop as well tonight through
Tuesday morning, first west of Rochester later this evening, then
transitioning east along the shoreline later tonight through Tuesday
morning. Expect a general 2-4" south of Lake Ontario with local 5-6"
amounts in the most persistent lake enhancement just inland from
Lake Ontario, and also across the Bristol Hills.

East of Lake Ontario, the period of snow and lake enhancement is
shorter, with 1-3" expected and local 4-5" amounts in a small area
on the northwestern slopes of the Tug Hill Plateau.

All headlines remain unchanged at this time. Even though snowfall
amounts aren't overly high, the worst travel conditions will be
during the Tuesday morning commute, and falling temperatures through
the event will likely result in very slick travel. The expected
travel impacts justify the Advisory even if some areas fall short of
4 inches. There will be just enough wind (northwest gusts 20-30 mph)
to support some limited blowing snow in open areas late tonight
through Tuesday morning.

The snow will quickly end from west to east from mid morning through
early afternoon Tuesday as deep moisture rapidly exits and is
replaced by a building surface ridge and dry air.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/...
Stubborn lingering lake effect snow southeast of Lake Ontario
Tuesday night will weaken as a mid-level trough pushes east out of
the region and ridging builds in across the area from the west. With
the ridging advancing into the area, warming temperatures aloft will
aid hindering the lake response. A shift in the winds from northwest
to west throughout the night will gradually shift what lake effect
is left northward.

The ridge will continue to build into the region Wednesday through
Thursday night and therefore will support dry quiescent weather
through the middle of the week. Additionally, with the ridging and
surface high overhead Wednesday and Thursday, corresponding warm air
advection will support temperatures to rebound to slightly above
normal for mid to late December with highs in the mid to upper 30s
and a few locations near or at 40.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
High pressure across New England will maintain dry weather Friday,
then a weak shortwave and low pressure trough might bring some light
precipitation Friday night and Saturday. Some models bring light
rain or snow with others keeping us completely dry. Little if any
snow accumulation. After this, large high pressure builds across the
area Saturday night through Monday, providing dry weather for
Christmas Eve and Day. Gradual warming trend during the period with
near normal temps Friday warming to about 10 degrees above normal.
High temperatures in the 40s on Christmas Day.

&&

.AVIATION /04Z TUESDAY THROUGH SATURDAY/...
Light snow will become widespread overnight, with embedded areas of
steadier lake enhanced snows south/southeast of Lake Erie and
Ontario with widespread MVFR/IFR CIGS and IFR VSBY. There may be a
few periods of moderate snow with VSBY down to 1/2 SM overnight
through early Tuesday morning southeast of Lakes Erie and Ontario.
Snow will taper off from west to east across western and
northcentral NY mid morning Tuesday through the mid afternoon.

Outlook...

Tuesday...Widespread IFR in snow early, tapering off and ending from
west to east mid-morning through mid-afternoon, thus conditions will
improve to VFR once snow ends.

Wednesday through Saturday...VFR.

&&

.MARINE...
Strong west to northwest winds tonight will continue to support
solid Small Craft Advisory conditions on both Lakes. The elevated
winds and waves will continue through Tuesday before diminishing
from west to east late Tuesday and Tuesday night as a ridge of high
pressure builds into the eastern Great Lakes.

&&

.HYDROLOGY...

Spotter and mesonet reports show between 2 and 3 inches of rain
has fallen across southern Lewis County, with 1.5 to 2.5 inches
across the rest of Lewis, Oswego, and Jefferson counties. This
rainfall produced water flowing over several low lying roads
which prompted closures, with a few roads still closed despite
the flood waters beginning to recede.

Attention is now turning to gauged rivers east of Lake Ontario.

A rapid rise on the Moose River to moderate flood stage
tonight. The river is expected to peak shortly after midnight
tonight, and remain above flood stage (12.0 feet) through
tomorrow afternoon. Impacts include not only the closure of
Moose River Road, but also some impacts in low lying areas of
Lyons Falls, Goulds Mill and Lyonsdale.

The Black River will also rise with recent rains. The Black
River at Boonville will crest very close to the flood stage of
10.0 feet around dawn Tuesday morning. The lower portions of the
Black River toward Watertown are not expected to crest until
Thursday. Flows this high on the Black River typically cause
minor lowland flooding in Lewis County.
