Area Forecast Discussion
National Weather Service Buffalo NY
953 AM EST Mon Dec 11 2017

.SYNOPSIS...
Surface high pressure briefly builds across the region with fair and
largely dry weather today. Low pressure will then cross the region
bringing periods of widespread accumulating snow that will last
through Wednesday. Several additional weak systems will then cross
the area late in the week along with additional chances of snow.

&&

.NEAR TERM /THROUGH TONIGHT/...
Regional radars show some areas of very light snowfall and flurries
across the forecast area this morning. With sfc high building in
from the west no significant additional snowfall accumulation
anticipated for the remainder the morning hours. Otherwise we can
expect a welcome quiet and largely dry day under the transient
surface ridge...with daytime highs ranging from the lower to mid 20s
across the North Country to the upper 20s/near 30 elsewhere.

Tonight...our brief period of fair and dry weather will quickly come
to an end...as a slowly strengthening surface low pushes eastward
from the Upper Great Lakes. Increasing warm air advection/isentropic
upglide out ahead of this system will result in widespread light
snow spreading across the region from west to east...with the snow
picking up a bit during the overnight hours as the main surface low
pushes to our western doorstep...and available moisture/lift both
ramp up. At this point total nighttime snowfall accumulations appear
as if they will range from 1-2 inches...with a few spots potentially
receiving between 2-3 inches. Low temps will range from around 20
east of Lake Ontario to the mid 20s elsewhere and should occur
during the first half of the night...before giving way to slowly
rising temps overnight in the warm advection regime out ahead of the
approaching surface low.

&&

.SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/...
...Accumulating synoptic snows will transition to another
potentially significant lake effect snow event...

The clipper low will be in the process of passing across the region
Tuesday morning. Widespread accumulating synoptic snows will be
ongoing. Ascent from this storm looks to be driven by warm advection
with particularly impressive isentropic lift. 00z NAM/GFS/GEM all
pretty similar in QPF guidance and supportive of additional snowfall
amounts of 2-3 inches through Tuesday morning.

As the surface low starts to push across northern New York Tuesday
afternoon, winds will veer to west then northwest while becoming
rather gusty as cold advection sets in. Winds in the wake of the
systems cold front may peak near 45 mph, especially south of the low
center across the western Southern Tier driving wind chills into the
teens.

Later Tuesday into Wednesday, a transition will take place into
another potentially significant lake effect snow event. Lake
enhanced/effect snows are expected to develop south or southeast of
the lakes as 850 mb temperatures cool in a northwest flow regime.
Profiles indicating many favorable lake effect parameters including
extreme over-lake instability, equilibrium heights rising to
near 15k feet and sufficient synoptic moisture and lift
intersecting the dendritic snow growth zone. Tuesday night into
Wednesday will likely be the most significant time period of
accumulating lake snows with equilibrium level peaking. Strong
winds could bring additional impacts with travel conditions
expected to be hazardous in heavy snow and blowing snow.

The core of the anomalously deep upper level low will pass over our
region Tuesday night and Wednesday which will bring the coldest air
yet this month with lows dipping into the single digits to teens
Tuesday night and only peaking in the teens to maybe 20 on
Wednesday. Lake effect then continues to look like it will begin to
weaken later Wednesday night as high pressure over the Ohio Valley
is forecast to nose north into western New York.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
Medium range guidance continues to indicate two more clipper lows
working across the Great Lakes later this week and next weekend. A
fair amount of uncertainty remains regarding the timing and
tracking of either of these clipper lows as well as any potenial
lake enhancement. Have continued broadbrush chance POPs for snow
showers through Saturday until more certain details arise in newer
guidance. Temperatures will remain below average through the end of
the week, as the region will remain embedded within longwave
troughiness. The eastern trough may break down over the weekend
which would potentially allow warmer air to return to our region.
Blend of model temperature guidance indicates temps may rise back to
normal by Saturday and possibly above normal for Sunday. If this
occurs rain/snow would be possible Sunday. Longer range guidance
suggests that this break from the cold may only be temporary, as a
longwave trough becomes re-established over the East in the week
following.

&&

.AVIATION /15Z MONDAY THROUGH FRIDAY/...
Regional radars show some areas of light snowfall and flurries
this morning. This light snow is producing some lower VSBYS/CIGS
resulting in IFR/MVFR east and southeast of both Lakes Erie and
Ontario. However, as the surface high continues to build in
from the west conditions will improve by early this afternoon
with mainly VFR across the forecast area.

These improved flying conditions will then deteriorate back to IFR
from west to east tonight as low pressure advances eastward across
the Great Lakes and spreads widespread light snow across the region.

Outlook...
Tuesday through Wednesday...Widespread IFR in periods of snow.
Thursday and Friday...Areas of MVFR/IFR with snow showers likely.

&&

.MARINE...
Weak high pressure will build across the region today...with winds
tending light and variable by midday/early afternoon. As a result...
lingering advisory-level conditions across portions of Lake Ontario
will come to an end this morning...with fairly quiet conditions then
following for this afternoon.

Low pressure tracking eastward from the Upper Great Lakes will then
pass directly overhead late tonight and Tuesday morning. Winds will
increase in the wake of this system Tuesday through Wednesday...with
another period of solid Small Craft Advisory conditions expected
areawide. On Lake Erie...it is not out of the question that conditions
could approach or even reach marginal gale force levels from Tuesday
into early Tuesday evening...however at this point confidence in this
remains too low for a Gale Watch.

&&

.BUF WATCHES/WARNINGS/ADVISORIES...
