Area Forecast Discussion
National Weather Service Buffalo NY
303 PM EST Fri Dec 16 2016

.SYNOPSIS...
Lake effect snow will taper off late this afternoon. After a brief
lull in activity this evening, a warm front will spread snow across
the region tonight into Saturday as it lifts north. The snow will
change over to rain Saturday and Saturday night as temperatures warm
into the 40s before falling sharply Sunday as a cold front crosses
the region. Temperatures will gradually rebound to around average
during the coming week.

&&

.NEAR TERM /THROUGH SATURDAY/...
The Lake Erie lake effect band previously discussed continues to
gradually make its way north across the Buffalo metro and has
maintained its vigor as it has moved onshore, dropping several
inches across the Buffalo metro over the last couple of hours. The
good news is that this band is finally moving entirely onshore
across the Niagara peninsula, and should weaken over the next hour
or two as it loses its overwater fetch. Meanwhile, lake effect
showers are taking shape east of Lake Ontario, and can be expected
to impact Jefferson and portions of Lewis county this afternoon and
during the evening hours, with a couple of inches of
accumulation possible.

Following the lake effect snow showers, we can expect a brief lull
in activity early this evening. However, the lull will be short-
lived, as a warm front lifting north will generate a broad area of
isentropic uplift-induced precipitation that will spread across the
forecast area from southwest to northeast tonight into Saturday
morning. General accumulations will run in the 2-4 inch range,
however higher elevation areas in the Southern Tier and North
Country will see slightly higher amounts in the 3-5 inch range, and
a winter weather advisory remains in place to cover these amounts.

Temperatures will gradually warm into the 20s overnight across
Western New York as warm air pushes northwards into the region.
Temperatures will continue to warm sharply on Saturday as 850mb
temps surge well above 0C. This will lead to a changeover from snow
to rain during the day as surface readings climb into the lower 40s
in western NY, with mid 30s in the North Country. It is worth noting
that the NAM suggests a sharper warm nose aloft pushing into the
region Saturday morning that would lead to a more significant threat
of sleet/freezing rain in the Southern Tier. However, it is an
outlier and the rest of the deterministic guidance suggests a more
gradual transition across the freezing mark, with little threat for
mixed precipitation, aside from some sleet near the PA border, and
perhaps across Lewis County, during the changeover from snow to rain.

Even as precipitation changes over to rain, it should be diminishing
to scattered showers as the region moves deeper into the warm sector
and the main zone of isentropic uplift moves off to the north-
northeast during the day. However, we may see a resurgence of
rainfall across far western New York late in the day, as the surface
low driving all of this precipitation nears the region.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/...
Saturday night a mid level trough will dig into the Upper Great
Lakes, with an associated surface low moving from near Toronto to
southern Quebec by early Sunday morning and deepening with time. The
digging trough and deepening surface low, along with a strong 150+
knot upper level jet, will bring a period of fairly strong ascent
Saturday night. Temperatures will hold in the upper 30s to low 40s
early in the night with dewpoints in the mid 30s, and the warmer
and more moist air and will maintain the areas of fog over the
snowpack, some areas becoming locally dense during the evening.

On Sunday any remaining synoptic scale precip will quickly end from
west to east as the cold front and mid level trough surge east.
Strong cold advection will force temperatures to fall through the
20s during the day. Some lake effect snow showers will develop east
of the lakes across the western Southern Tier and Tug Hill region,
but a dry airmass will keep this limited. Lake effect snow will
continue southeast of the lakes Sunday night as boundary layer flow
becomes WNW. The snow may become a little better organized as shear
decreases and convergent flow develops over the lakes, especially
across Wayne, Northern Cayuga and Oswego counties. These areas will
receive a couple inches of snow during Sunday night, generally 2 to
4 inches. The lake snow bands will weaken move to the north on
Monday as winds become southwesterly. Skies will clear Monday
afternoon and evening with the influx of drier air.

Temperatures will be in the upper single numbers to lower teens
Sunday night with lower single numbers east of Lake Ontario,
following the plummeting reading's as the cold front crossed the
region. Monday's high temperatures will be in middle teens to lower
20s and back to the teens for overnight lows as the pool of cold air
remains over the region.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
During the course of Monday and Monday evening...leftover scattered
lake effect snow showers east of the lakes will lift northward to
the Buffalo and Watertown areas and fall apart altogether as high
pressure builds across the region...the low level flow backs around
to southwesterly and becomes rather sheared...and warm air advection
develops aloft. Otherwise...dry and cold weather will prevail...with
highs in the lower to mid 20s Monday followed by lows in the teens
Monday night.

Widespread dry and quiet weather along with a notable warming trend
will then follow for both Tuesday and Wednesday...as the surface
ridge will be anchored either across or a bit to the southeast of
our region...with our area under the influence of attendant drier
air and subsidence. The large scale pattern across North America
will become zonal, allowing Pacific air to flood east across the
nation and bring a warming trend. Speaking more specifically with
respect to temps...daytime highs should rebound to within a few
degrees of the freezing mark on Tuesday...before climbing into the
upper 30s to lower 40s on Wednesday. Meanwhile...nighttime lows will
recover into the 20s.

The dry weather will then come to an end on Thursday as the next low
pressure system works into our region and brings us our next general
chance of precipitation to close out the period. With the medium range
guidance showing rather large disparities in the track/strength of
this low and consequently temperatures across our region...for now
a generic low chance of rain and snow for Thursday appears to be the
best course to follow...along with with forecast highs close to a
consensus of the available guidance.

&&

.AVIATION /20Z FRIDAY THROUGH WEDNESDAY/...
A lake effect snow band shifting north across Lake Erie will bring a
period of IFR conditions to KBUF between 18-21Z. This band should
fall apart as it shifts north across the Buffalo metro, with a few
stray showers brushing KIAG. Confidence in intensity of showers is
not high enough at KIAG to warrant anything more than a VCSH line.
Likewise, lake effect showers on Lake Ontario will re-consolidate
this afternoon, and are expected to affect KART late this afternoon,
with brief periods of IFR conditions possible. As with Lake Erie,
these showers should continue to shift to the north through the late
afternoon/early evening, with VFR conditions returning by 00Z Sat.

Elsewhere, VFR conditions will prevail through the rest of the day.
A warm front lifting across the region tonight will bring a round of
widespread snowfall to the area, with IFR conditions developing
across the region from SW-NE overnight and lasting through the
balance of the TAF period.

Outlook...

Saturday...MVFR/IFR. Snow and rain likely.
Saturday Night...IFR.
Sunday...MVFR early...then VFR.
Monday...Areas of lake effect snow...otherwise VFR.
Tuesday...VFR.
Wednesday...Mainly VFR.

&&

.MARINE...
Southwesterly winds will back to the south tonight and weaken,
allowing small craft advisories to be dropped later tonight, with
the exception of the far eastern end of Lake Ontario. A surface low
passing across the region should keep winds relatively light
Saturday into Saturday evening before westerly winds freshen again
in the wake of a strong cold frontal passage Saturday night into
Sunday. This will necessitate another round of small craft
advisories that will likely be needed through Sunday night, before
high pressure and light winds return to the region Monday.

&&
