Still 4 days out, but the trend this year is further NW as we get inside day 4. 

If you're going with the this track is different, and I'm in agreement with that, then I believe this is the euro over amping itself as it normally does...o think with the impending pattern change coming the models are all having a difficult time exactly how that'll happen. This may not be set until Friday

We actually never flip over here lol

It does develop a secondary, late but it acts as a double barrel, becomes the primary in the gulf of maine..Not sure what effect this would have on enhancement..

It's funny how it shows mixing at ksyr with heavy snow all around it lol

Not that I buy that..

I feel horrible for upstate but there is no better time for a storm to nudge north than this weekend when I'll be in Mont Treblant Quebec!  Would love to catch a solid powder day as they have been non-existent on the East Coast this year.  Fingers crossed.  Some of the earlier runs were good for both NY and Quebec, would have loved to see one of them come to fruition.

I'm also glad as it means I probably wont go through the hell of canceled flights I went through last year trying to get out out of Buffalo Saturday morning...

Hwo 

An area of low pressure will cross the area Wednesday night through
Thursday, producing accumulating snow. The greatest accumulations
will be found across the higher terrain of the Tug Hill and western
foothills of the Adirondacks, where 4 to 8 inches of accumulation is
possible.

Deep low pressure will then move across the region this weekend.
This system will produce widespread accumulating snow on Saturday
and gusty winds Saturday night and Sunday. Additional accumulations
of lake effect snow will be possible on Sunday when the gusty winds
could support blowing and drifting snow in open areas.

A rather potent mid level shortwave and surface low will cross
the eastern Great Lakes Wednesday night, exiting into New
England on Thursday. This compact, fast moving system will usher
much colder air back into our region and mark the start of a
much colder and more wintry pattern after a long period of mild
weather.

DPVA ahead of the mid level trough and a wing of warm advection
ahead of the surface low will support a few showers spreading
quickly from west to east across the region Wednesday evening.
Temperatures will rise into the low or even mid 40s from western
Oswego County westward Wednesday evening, so most of this will
initially fall as rain. The one possible exception is east of Lake
Ontario, where colder temperatures surface and aloft may support
some wet snow right from the onset. Given the warm temperatures, any
snow accumulation will be minimal through most of Wednesday night.
The one exception will be the higher terrain of the Tug Hill and
western Adirondacks, where initial colder temperatures and upslope
flow may support a few inches of accumulation Wednesday night.

Strong cold advection will develop late Wednesday night following
the passage of the surface low center, which moves almost directly
overhead. A period of deep wrap around moisture, strong DPVA with
the mid level shortwave, and developing lake instability will
support snow showers becoming more widespread late Wednesday night
and Thursday morning as temperatures drop rapidly below freezing.
The higher QPF amounts during this period will be closely tied to
terrain, with developing WNW upslope flow combined with increasing
lake instability providing enhancement. This will target the Tug
Hill Plateau east of Lake Ontario, and the Chautauqua Ridge, Boston
Hills, and Wyoming County east of Lake Erie. Both areas should see a
period of accumulating snow very late Wednesday night through
Thursday.

Later Thursday afternoon and Thursday night the orographic
enhancement will give way to a more pure lake effect signal as a
cold pool aloft settles over the eastern Great Lakes. This will
support lake induced equilibrium levels of 8-10K feet Thursday,
slowly dropping to around 6K feet by late Thursday night as
inversion heights lower. A favorably deep mixed phase layer will
reside within the cloud bearing layer, supporting large, fluffy
dendrites. Boundary layer flow will become northwest, supporting
fairly widespread snow showers and narrow bands of snow southeast of
the lakes.

A lot to get through lol


Southeast of Lake Erie, the snow will be most persistent across the
higher terrain of the Chautauqua Ridge, where a Lake Huron
connection may also provide some enhancement. This snow will be most
widespread Thursday morning, before slowly backing off in coverage
and intensity Thursday afternoon through Thursday night. Expect
total accumulations of 4-6 inches across the higher terrain from
late Wednesday night through Thursday night.

Southeast of Lake Ontario, the initial upslope driven response
across the Tug Hill will evolve into lake effect snow showers
southeast of the lake Thursday afternoon and Thursday night. This
will produce some modest accumulations from Wayne to Oswego
counties, although the lack of terrain to help in this area and the
lack of a Georgian Bay connection will keep accumulations limited to
2-4, or perhaps 3-5 inches in the most persistent bands. The heavier
snow amounts will end up on the Tug Hill, with totals of 4-8 inches
from Wednesday night through Thursday night from the initial
synoptic system, then lake enhanced upslope flow.

Latest high resolution guidance also suggests a Georgian Bay band
will meander through the area between Buffalo and Rochester,
possibly extending down into the western Finger Lakes. This may drop
a few inches locally on Thursday if the band is able to remain in
one location for a few hours. Outside of these main lake effect
areas, sporadic snow showers will produce a dusting to an inch of
accumulation Thursday.
