Area Forecast Discussion
National Weather Service Buffalo NY
238 PM EST Sat Jan 28 2017

.SYNOPSIS...
Colder air will bring more typical midwinter conditions through the
weekend and much of next week. Significant lake effect snow will
continue east of the lakes through the end of the weekend. A clipper
system will then bring widespread snow Tuesday through Wednesday of
next week.

&&

.NEAR TERM /THROUGH SUNDAY/...
A well defined mid level shortwave will approach the area this
evening, with an associated surface low passing by just north of
Lake Ontario. This feature will continue to support boundary layer
winds backing to the southwest this evening, forcing lake effect
snow to focus northeast of the lakes on a mean 240 degree flow into
Buffalo and Watertown. Outside of lake effect areas, expect a few
snow showers through the first half of tonight with the passage of
the mid level shortwave, producing a spotty dusting to an inch.

Off Lake Erie...

Radar imagery showing a broad area of light to moderate snow across
all of the Niagara Frontier at mid afternoon. This snow is from a
combination of forcing mechanisms, including lake enhancement,
frictional convergence at the northeast end of Lake Erie, and large
scale ascent from an approaching mid level shortwave.

Lake induced equilibrium levels fall to around 5K feet during the
late afternoon and early evening, and that combined with increased
shear will keep any lake snow somewhat disorganized through early
evening with nothing more than briefly moderate snow rates. As the
mid level trough approaches, flow will become better aligned around
mid evening and equilibrium levels will rapidly rise to around 10K
feet. This should allow the broad area of light snow showers to
consolidate into a stronger single band over the Buffalo Metro area
to western Genesee County around mid evening. This band will drop an
additional 3-5 inches in the advisory area from late afternoon
through the early overnight with snowfall rates briefly reaching 1-2
inches per hour.

Boundary layer flow will then quickly veer more westerly later
tonight, which will push the strengthening band of snow onshore
along the entire Lake Erie shore from Hamburg to Ripley, then inland
across the higher terrain. Expect 1-2 inch per hour snowfall rates
to continue overnight as the band pushes back into the Southern
Tier, with 4-6 inches of additional accumulation.

Sunday morning expect an east/west oriented band of moderate lake
effect snow to continue across the western Southern Tier with decent
snowfall rates. This band will likely weaken by late morning into
the afternoon as a push of drier air and divergent low level flow
crosses Lake Erie, disrupting the lake effect process. Expect an
additional 2-4 inches on Sunday in persistent bands across the
Southern Tier, with most of that falling in the morning.

Storm total snowfall has been adjusted downward from previous
forecasts given how the band has been moving around and not locking
in over any one location for very long. As of 7AM this morning the
highest accumulations have been around 10 inches across the higher
terrain east of the lake. Considering the additional snowfall
expected, maximum storm totals should reach the 15 to 20 inch range
across the higher terrain inland from the lake.

Off Lake Ontario...

A more pure looking band of lake effect snow earlier today has now
broadened out and weakened. This more broad area of moderate lake
effect snow will continue to lift north from the Tug Hill into
Jefferson County through early evening with snowfall rates still
reaching an inch per hour at times. Expect another 2-4 inches of
accumulation through mid evening in the more persistent bands.

The relatively lighter lake effect snow will continue mainly across
Jefferson and far northern Lewis County this evening with increased
shear and lake induced equilibrium levels around 6-7K feet
preventing any strong organization. Some upslope snow will keep
persistent snow showers going across the Tug Hill as well.

Overnight expect lake effect snow to intensify again with the
approach of the mid level shortwave, which will force equilibrium
levels to rise to 10K feet again. Flow will also become better
aligned and more convergent from the southwest. Expect a stronger
band across central Jefferson and Northern Lewis counties to settle
back south towards the Tug Hill by Sunday morning with snowfall
rates increasing to 1-2 inches per hour overnight. Expect additional
amounts of 4-7 inches tonight from the northern Tug Hill into
portions of southern and central Jefferson County.

On Sunday mesoscale model guidance including the Canadian GEM and
3KM NAM-RR suggest the band will become fairly intense for a brief
period of time in the morning, targeting the central Tug Hill along
the Oswego/Jefferson County line. Snowfall rates may increase to 2-3
inches per hour during this time. The convergent flow will become
disrupted during the afternoon, forcing the band to weaken and sink
slowly south through Oswego County. Expect additional amounts during
the day Sunday of up to a foot across the central Tug Hill, and 3-5
inches elsewhere across lower elevations east of Lake Ontario.

The band will also start brushing the south shore of Lake Ontario on
Sunday, with spotty 1-2 inch amounts from Niagara to northern Cayuga
counties generally along and north of Route 104.

Storm totals have been modified to refine the higher amounts to a
smaller area of the Tug Hill. About a foot and a half has fallen as
of 7AM this morning across the southern Tug Hill. This, combined
with additional amounts should still bring totals to over 3 feet in
a small area of the southern Tug Hill, with amounts quickly dropping
off to less than a foot at lower elevations surrounding the Tug Hill.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH WEDNESDAY/...
This period will open with a surface trough and associated snow showers
sliding across our region from northwest to southeast early Sunday evening.
Behind this feature the low level wind field will quickly veer to west-
northwesterly...which will in turn act to advect colder air across our
region commensurate with the passage of the main upper level trough axis.

The cold air advection regime will result in 850 mb temps falling to
the -15C to -18C range Sunday night...then remaining in this general
vicinity through Monday. Coupled with fairly plentiful moisture
lingering below equilibrium levels of around 10 kft...this will set
the stage for continued lake effect snows through Sunday night and
Monday morning...this time predominantly southeast of the lakes given
the prevailing west-northwesterly flow.

While the activity will be multi-banded in nature and there will also
be some shear in place during this time frame...the favorable thermal
and moisture profiles would suggest that the potential for at least
some additional advisory-worthy snows will exist southeast of both lakes
through Monday morning. Off Lake Erie these would primarily be across
Chautauqua county and immediately adjoining portions of Southern Erie
and Cattaraugus counties...while the Lake Ontario activity could focus
anywhere from Niagara to southern Oswego counties dependent upon the
evolution of an upstream connection to Lake Huron...the strength and
position of which varies amongst the shorter term guidance packages.
Given the existing LES warnings off Lake Erie and still plenty of
uncertainty on the exact strength and placement of the best Lake Ontario
lake snows...will hold off on any additions/extensions to the current
Lake Effect headlines for now...though these will probably become
necessary over the next day or so.

Outside of the main lake effect areas...the rest of the region should
see more scattered snow showers and relatively minimal accumulations
Sunday night and the first part of Monday...with these mainly focused
around the passage of the surface trough Sunday evening and around the
edges of the main lake bands. Under the incoming colder airmass...lows
Sunday night should settle into the teens south of Lake Ontario and to
around 10 above across the North Country...with highs on Monday mostly
reaching into the lower to mid 20s.

As we move into Monday afternoon and evening...building surface-based
ridging and attendant mid level drying...falling inversion heights...
and increasing shear will result in the lake snows steadily weakening
while also moving back northward in response to steady backing of the
low level flow. Expect that these will have deteriorated to just some
leftover scattered light snow showers by Monday evening...before
shearing out and ending altogether northeast of the lakes Monday night.

Immediately following the demise of our current round of lake effect...
our attention will turn back to the synoptic scale later Monday night
through Tuesday night as a fast-moving shortwave and attendant clipper
system slides southeastward from the Upper Great Lakes to the New
England coastline. Warm advective lift and moisture spreading across
our region out ahead of this system will likely bring widespread
light to moderate snow to our region later Monday night through
Tuesday...with the snow then likely to continue right through Tuesday
night as the clipper passes by just to our north. The clipper will
also briefly spread warmer air into our region Monday night and
Tuesday...with evening lows mainly in the teens (except around 10
above across the North Country) followed by steadily rising temps
the rest of Monday night...then highs reaching into the lower to mid
30s in many locations on Tuesday.

Following the passage of the clipper system...a westerly to west-
northwesterly flow of slightly colder air will spread across our
region on Wednesday. This will likely result in some lake effect
snow showers downwind of the lakes...though with temps aloft marginal
for a lake response these may not amount to all that much through
the course of the day. Otherwise much more scattered snow showers
can be expected...with daytime highs ranging from the upper 20s
across the higher terrain to the lower to mid 30s across the lower
elevations.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
Given persistent cyclonic west-northwesterly flow aloft and 850mb
temps that will remain relatively stable in the -12C to -16C range
through at least Thursday, with good agreement amongst the models,
confidence is fairly high that we will see lake effect snows linger
east-southeast of the lakes at least through Thursday. Commensurate
with the falling temperatures aloft, surface temperatures during
this period will fall back below average, with highs in the 20s and
lows in the teens to single digits, coldest in the Southern Tier and
North Country.

&&

.AVIATION /20Z SATURDAY THROUGH THURSDAY/...
Lake effect snow will continue northeast of Lakes Erie and Ontario
through this evening with areas of IFR VSBY, including KBUF and
KART. Lake effect snow will likely intensify near KBUF later this
evening. The stronger portion of the band may briefly impact KBUF
from about 01Z to 04Z with near airfield minimum VSBY before moving
south into the western Southern Tier overnight, reaching KJHW late
tonight and early Sunday. This band will continue to produce local
IFR, with the heaviest portion likely producing less than 1/2 mile
VSBY.

East of Lake Ontario, lake effect snow will continue near KART
through tonight with IFR before moving south across the Tug Hill
Sunday, centering on Oswego County by late in the day. The western
portion of this band will likely brush the south shore of the lake
with spotty IFR VSBY at times, but most of this should remain north
of KROC through late afternoon.

Outlook...

Sunday night and Monday...IFR/LIFR in lake effect snows east of the
lakes...with VFR/MVFR prevailing elsewhere.
Tuesday and Wednesday...Areas of IFR with snow likely.
Thursday...VFR/MVFR with scattered snow showers. Local IFR in lake
effect snow east of the lakes.

&&

.MARINE...
A strong area of low pressure will continue to spin over Labrador
through Sunday and maintain moderate to strong westerly flow on
Lakes Erie and Ontario. This will maintain Small Craft Advisory
conditions on both lakes through the end of the weekend. High
pressure will build into the Lower Great Lakes Monday with
diminishing winds.
