area forecast discussion
national weather service binghamton ny
300 am est Mon dec 11 2017

Synopsis
Lake effect snow will gradually diminish to scattered morning
snow showers and flurries. After a quiet afternoon, a clipper
system will quickly move through tonight into early Tuesday
with accumulating snow. This will be followed by lake effect
snow Tuesday afternoon through Wednesday night in central new
york and perhaps some of the northern tier of pennsylvania.

Near term until 6 pm this evening
3 am update...

clipper system tonight-early Tuesday, and the arctic air and
lake effect snow that will follow, are the main forecast
concerns at this moment in the big picture; but first we have
lingering lake effect to contend with this morning. For more
details on the tonight through midweek period, refer to the
later portions of the area forecast discussion.

Lake ontario band shifted north of the area much of yesterday,
but with approach of a shallow cold front it is now reorienting.

It will bodily carry through northern oneida county during the
next several hours, likely reducing visibility to about a mile
while dropping another quick 1 to 2 inches north of the ny
thruway. We will allow winter weather advisory to continue up to
the scheduled expiration of 7 am this morning. As winds veer
northwesterly behind the front, inversion heights will also
rapidly drop to below the dendritic growth zone, which along
with drier air will allow the lake effect to transition to
multi-band snow showers and flurries after dawn this morning,
before ending around midday. So south of the thruway to about as
far as moravia-cortland-pharsalia-morrisville-waterville,
accumulations this morning should be limited to a fluffy dusting
to around an inch. Elsewhere just a few flurries are expected as
the weak front passes; many locations especially in northeast pa
will see nothing at all due to the amount of dry air.

Though there will be a gradual decrease in lake clouds, high
thin clouds will quickly stream in ahead of the approaching
clipper, and then thicken with time. This will hold highs back
to generally in the mid 20s to mid 30s range.

Short term 6 pm this evening through 6 pm Tuesday
330 pm update...

model guidance is showing increasing confidence in
a low pressure system moving across ny Monday night into the day
on Tuesday. The latest guidance tracks the center of the
surface low over lake erie, then to a position near rochester by
Tuesday morning. Ample warm air advection precipitation(snow) is
forecast to develop out ahead of this low pressure system,
beginning late Monday evening for much of our forecast area.

With the track of the low to our north, this will keep surface
winds out of the south-southeast and breezy at times (10-20
mph). This type of flow will keep some areas downwind of the
higher catskills and especially poconos shadowed from the higher
precip snow rates. By midday Tuesday the surface low begins to
jump, and reform along the new england coast. This could allow
for some enhanced wrap around snowfall to impact the far eastern
portion of our CWA during this time... But the snow will really
pick up just off to our east... Over far eastern ny and new
england. Right now, storm total snowfall from this first system
is forecast to range from about 1-3 inches for our NE pa
zones... With 2-4 inches for our ny zones... Except 4-8 inches in
oneida county where the southerly flow upslopes in the southern
tug hill plateau. Will hold off on any winter headlines at this
time, and let the evening overnight shift take another look at
the latest model guidance trends.

Long term Tuesday night through Sunday
330 pm update...

closed mid upper low moves overhead Tuesday night into
Wednesday as strong cold air advection continues. This will
bring lake effect enhanced snows across much of the area with a
northwest flow and deep moisture. Best chance for potentially
significant accumulations will be over over the higher ground of
central ny, particularly the finger lakes but expect measurable
snow down into nepa as well. It is likely that headlines will
eventually be needed for parts of the area for this event.

Preliminary forecasts point to the potential for 3-6 inches of
snow across most of our ny zones... With locally higher amounts
were the lake bands set up. Amounts during this time will be
lighter in NE pa, and could range from 1 to 3 inches, mainly in
the higher terrain. Little change through Wednesday as 850 mb
temps bottom out near -18c over the area and the NW flow lake
snows continues.

Flow becomes more westerly and relaxes on Thursday so snow
showers will taper off. However, unsettled weather will continue
through Friday with trofiness aloft, a clipper moving into the
great lakes, and systems running up the coast to our east.

Confidence in forecast is low to moderate until Friday when
global models diverge quite a bit on positioning and timing of
disturbances diving around the base of the trof and interacting
with the front along the coastal plain. Chance pops during this
time and some moderation of temperatures with flatter flow and
slight warm advection. Temperatures look to potentially warm
above freezing into the mid-30s to lower 40s by next Sunday, as
a storm system passes by well to our north. This system will
bring chances for rain and snow showers, and perhaps some mixed
precipitation.

Aviation 08z Monday through Friday
Lake effect snow will wind down this morning, but not before
causing times of 1-4 mile visibility for krme-ksyr, and very
briefly at kelm-kbgm-kith as a weak front passes. Light
southwest wind will veer to west-northwest behind the front but
less than 10 knots, then variable late afternoon to light
southeast evening. ThoughVFR areawide this afternoon, a clipper
system will already start moving in towards 06z Tuesday, just
reaching the ny terminals with MVFR to ifr snow with further
deterioration likely inbound; eventually including kavp.

Outlook...

late Monday night through Tuesday... A period of snow likely
with restrictions as a clipper system moves through the region.

Tuesday night through Friday... Snow showers and associated
restrictions, mainly ny terminals due to lake effect.

Bgm watches warnings advisories
Pa... None.

Ny... Winter weather advisory until 7 am est this morning for nyz009.
