Crowd is gathering in Bryant Park for the most important Euro run in the history of humanity.

It's tiring reading the back and forth about starting a thread vs not starting a thread.  Who cares.  There's no such thing as a jinx and even though the models have been performing poorly at this ran

this looks ideal for a 20-30" band across the metro

.DISCUSSION...
.KEY MESSAGE 1...
Confidence has increased to the point where winter storm and
blizzard warnings have been issued across the forecast area.

A major winter storm is forecast to impact the area Sunday into
Monday. Model guidance has congealed in taking a deepening low
off the Mid Atlantic coast Sunday northeast to near the 40N...70W
benchmark Monday. This track is often favorable for all snow
across the region. The low undergoes explosive deepening in 12h,
tracking from near the North Carolina coast Sunday afternoon to
east of the Delmarva Sunday night. Most of the guidance shows
pressure falls on the order of 25 to 30 mb in 12 hour. The low
deepens to around 970 mb as it approaches the benchmark Monday
morning.

This storm, expected to be early 1000 miles across in diameter,
will produce heavy precipitation and gale to storm force winds
over the adjacent coastal waters. Model soundings show boundary
layer winds along the coast 40-60kt with decent mixing. Coastal
locations can expect to see gusts up 40 to 50 mph, possibly even
stronger across far eastern LI and southeast CT. Even inland
area will see near blizzard conditions with winds just a bit
weaker. The highest winds will occur Sunday night into the
first half of Monday.

Liquid equivalent amounts of around an inch across far NW
portions of Orange county will be near an inch, with upward of
an 1.5" at the coast. There is even some guidance suggestive of
amount around 2 inches at the coast. However, while there is
good overall agreement in the guidance, there still have been
small adjustments east and west and a consenus forecast (blend
of WPC and NBM) was used. Snow ratios are expected to start of
around 10:1 and then possibly get up to 12-13:1. Temperatures
initially on Sunday may get into the lower and mid 30s, expect
most locations to fall to around freezing if not lower as the
heavy snow develops in the afternoon. So ratios right off the
bat along he coast may even be lower for a short time.

Snowfall amounts of 14 to 18 inches are forecast along the coast
with 10 to 14 inches across the interior. NBM deterministic
forecasts point to amounts of 14 to 24 inches across the area,
highest along the coast. But due to some wobbling of the low
track a bit, we do want to see more continuity. NBM 90th
percentile has amounts of 2 to 3 ft. The 00Z LREF (EPS, GEPS,
and GEFS) mean has about a foot at the coast and 7 to 8 inches
across far western sections of Orange County in the Lower Hudson
Valley. The EPS is contributing lower amounts with a more
eastern solution. Should it come a bit more west, than the
higher totals are not out of the realm possibility.

Snow is forecast to develop from SW to NE on Sunday, in the
morning from NYC and points north and west, and the in the
afternoon for the remainder of the area. The heaviest snow and
wind will be Sunday night into Monday morning. Snow will end
from west to east during the afternoon hours.

.KEY MESSAGE 2...

Strengthening E-NE winds Sunday into Sunday night could produce
a surge of 2.5-3.5 ft, producing widespread moderate to
locally major coastal flooding along the back bays of western
Suffolk and srn Nassau, Peconic Bay, and western Long Island
Sound, and widespread minor to locally moderate flooding in NY
Harbor and Jamaica Bay, the lower Hudson River, and ern Long
Island Sound. The main high tide cycle of concern is Sunday
night. Areas of dune erosion are likely, with localized
overwashes possible along the ocean beachfront Sunday night into
Monday morning.

Additional coastal flooding will likely linger into the
Monday afternoon high tide cycle, with a strong northerly flow
limiting impacts somewhat to minor/locally moderate categories.

Boxing Day still seems like one of the best analogs to me and the same model led the way on both.

Agree but praying this one turns out different for me. I got like 7” and 15 miles east had over 20”. Could be similar lol

Start time guesstimate anyone ? 8 am ?????? and when does she get cranking is it in the afternoon or at night ?

I think if you're north of 195 it's snizzly for a bit. Non accumulating snow until early afternoon, cranks as it gets dark.

This will be the longest stretch of solid snow cover over 1 inch that I can remember in my area.  Minus where winds blew snow to nearly the grass... wow and not hitting 40 since jan 22... wonder how long can keep this record going!?

Good morning, the late-"Icehater," a great poster on the old NYC Metro forum wrote that the temperature during the "Lindsey Storm" of February, 1969 hovered around 34 F and never went below freezing.  Would you have temperature data for that storm for CPK or other points? FD

The low temperatures were:

EWR: 24
ISP: 27
JFK: 26
LGA: 26
NYC: 26

north of I-95 ?? please explain

That's a 1 not an I. I think intensity is light enough for the NYC metro that not much accumulates until mid afternoon. There's not much forcing away from the sfc low until all the energy gets into the trof and it detonates.

195 is like exit 100 on the parkway

Pretty much. It's exit 98. I used to live in Toms River, NJ (moved this year) and hated how it didn't snow there for the past 3 to 5 years except once. Wish I could go there one more time as it much jackpot for this storm.
