What forecasters said that day

The local office's own words before this blizzard warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS New York, NY wrote its last area forecast discussion before this blizzard warning went out at Jan 3, 1:26 PM EST, 1 hour 54 minutes earlier.

Area forecast discussion, Jan 3, 1:26 PM EST, 1 hour 54 minutes before
Area Forecast Discussion...CORRECTED
National Weather Service New York NY
126 PM EST Wed Jan 3 2018

.SYNOPSIS...
High pressure slides slowly offshore today. Meanwhile, low
pressure develops off the Florida coast and explosively deepens
as it tracks north, passing southeast of the local area Thursday
afternoon. Arctic high pressure follows behind the departing
storm system for Friday into Saturday. A warmup then ensues late
in the weekend into early next week ahead of an approaching
frontal system.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Today should be the "warmest" day across the Tri-State area
since Christmas Day. Not that this is saying much when we still
stay below freezing. A few spots dropped into the minus single
digits this morning given the clear sky, light wind and snowpack
on the ground. But even parts of North Florida have had snow and
sleet this morning which just about says it all with how cold it
is in the Eastern United States. Other than a few tweaks to
hourly grids, no significant changes were made this morning.

The polar trough digs to the Gulf Coast, following two separate
shortwave/jet streaks diving down the back side. Ahead of it
rising heights aloft for the region.

At the surface, high pressure slowly slides offshore keeping
conditions dry and with a moderating airmass in return flow, not as
cold. Meanwhile, low pressure that will affect our weather tonight
through Thursday begins to take shape just off the east coast of
Florida.

Plenty of sunshine early will give way to increasing high clouds
later on today. After a chilly start to the day, temperatures
rebound into the 20s, approaching 30 degrees in spots.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY NIGHT/...
** Heavy snow with strong winds expected for Suffolk County
and much of Southern CT Wed Night through Thu - Blizzard Conditions
Possible **

** Light to Moderate snow accumulations and strong winds expected
Wed Night through Thu for remainder of the region - Moderate to
Heavy snow accumulation possible **

Polar trough will continue to dig into the SE US, aided by one
strong shortwave/jet streak diving through the Gulf Coast this
morning, and by a second separate vigorous shortwave/jet streak
diving through the lower Mississippi River Valley this morning.
As mentioned over the last few days, there are still subtle
model differences in the timing/location of phasing of the
above shortwave energies as they round the base of the digging
trough this evening/tonight, as well as a final interaction with
a third shortwave/jet streak (diving through the Upper
Mississippi River Valley this morning) off the SE US coast late
tonight into Thursday morning. This interaction will affect the
track and timing of explosively deepening low pressure. The
other factor appears to be models having difficulty with
convection development and vorticity feedback off the US east
coast as this intense mid/upper level energy interacts with a
sub-tropical moisture plume, which also could play a
significant factor in low pressure track.

Operational models have already shifted about 50 miles closer
to LI with track of low pressure by late Thursday than 24 hrs
ago, with consensus track of a 955 to 960 mb low pressure
system tracking over or just se of the 40/70 lat/lon benchmark.
The exact phasing evolution will determine any additional
forecast track adjustment, with GEFS/ECMWF/SREF still showing at
least 150 miles of spread in members within 24-36 hrs. This
range of potential shift would have significant implication on
westward expanse of frontogenetically forced heavy snow banding,
and strong to damaging wind fields with this intense low. In
fact 06z NAM, has taken a significant shift westward from 00z
with its frontogenetic forcing, showing potential for 1 ft+ snow
across the entire area. For this reason, NHC will be doing a
reconnaissance flight and several dropsondes this
afternoon/evening off the Fl/SE US coast to better capture this
phasing and convection latent heat release in the models.

For now, based on above and consensus 00z operational/ensemble
track and uncertainty, expectation for snow to develop from S/SE
to N/NW tonight as polar and southern stream jet energy phase.
This will place the region under deep lift of right rear of 150
kt jet streak, with subtropical moisture being fed by cold
conveyor into the region. Then as phasing shortwave energy and
rapidly deepening low pressure move up the coast tonight, LI
and SE/SC CT are expected to fall under strong low- mid level
forcing late tonight into Thu afternoon. Heavy snow banding is
typically under and just to the NW of that. Also potential for
enhanced updraft/convection through CSI as indicated by negative
epv above the frontogenetic forcing. SPC SREF/SPC HREF
corroborate this through indicating a moderate to high potential
for 1 per hour snowfall rates during this time, and possibly 2
inch per hour. Once again though, this banding could
expand/shift westward by 50 or more miles, which is in the realm
of QPF spread seen in GEFS and SREF, which have a reasonable
range of 1/10 to 1 inch across NYC!

So overall, the probability for a light to moderate accumulating
snowfall event for the entire area is high late tonight into Thu
eve, with a heavy snowfall expected for much of LI and CT. Potential
still exists for the entire region to see a moderate to heavy snow
event.

A good middle of the road compromise for qpf with the
track/banding uncertainty is staying close to GEFS/SREF/ECMWF
ensemble means. This was blended in with WPC for consistency.
This results in 1/2 to 1 inch qpf across LI/SE CT, 1/4th to 1/2
inch across NYC/NJ metro and SW CT, and up to 1/4 inch to the
NW. Snow ratios are a bit tricky with strong omega in the
saturated snow growth and eventually in the warmer riming
saturated region, especially for eastern and coastal areas. So
a blend of snow ratio algorithms and WPC was used that appear to
capture this. This points towards a likelihood of 6 to 12 inch
snowfall for E LI/SE CT, 4 to 7 inches westward to the Hudson
River, and 1 to 4 inches to the NW. As mentioned, this remains a
fluid situation based on model spread, with potential for these
numbers to go down, but still seems more reasonable upwards
based on model trends and mode of SREF/GEFS/ECMWF ensemble
members compared to operational runs. This higher trend is
reflected in latest WFO/WPC snow probs, with high probs of
greater than 6 inches of snow across E LI/SE CT and low to
moderate probs to Hudson River. A significant jump in the
reasonable worse case has also been noted, with 1 in 10 chance
of seeing more than 12-16 inches of snow across much of LI/CT, 8
to 12 inches of snow across NYC/NJ metro to Hudson River, and 4
to 8 inches N & W still in play. In fact, the 06z NAM has come
in with 1 1/2 to 2 1/2 inches of liquid QPF for much of the
region, which is within SREF ensemble spread.

The other hazard with this storm continues to be strong winds,
with a blend between GFS/NAM profiles pointing to likelihood for
30 to 40 mph gusts along the coast Thu aft/eve, and 45-50 mph
gusts for eastern coastal areas. This will lead to blowing and
drifting snow, possibly near whiteout conditions in the warned
areas, as well as some downed tree limbs and power lines.

Based on above, have upgraded to winter storm warning for Suffolk
and SE CT with 6 to 10 inches of snow expected and potential
for 1 ft or more. No blizzard warnings at this time, as
despite likely high winds, heavy snowfall and low vbsy, but low
confidence that sub 1 ft snowfall will have significant enough
impacts. If expected snowfall amounts increase today, and
therefore high end impacts, a blizzard warning will be hoisted.
A Winter storm watch issued for NYC metro, Nassau and SW CT
with 3 to 7 inches expected and potential for widespread in
excess of 6 inches. To the N&W of this region an advisory is
likely, but not enough confidence in 6+" for watch. Have held
off on headlines after collab with surrounding offices in this
region due to 3rd period timing and uncertainty. Again, if 6z
NAM is pre-cursor, we may see the warning upgraded another tier
westward or possibly more.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
** Dangerous cold for Friday into Saturday **

Global models are in good agreement with a strong surge of
arctic air arriving behind the departing storm system.
Temperatures Friday into Saturday will average nearly 25 degrees
below normal with highs in the upper single digits to lower
teens, and lows below zero across the interior and the single
digits near the coast. Furthermore, strong NW winds both days
will produce below zero wind chills, which at night will range
from -15 to -25. Wind child advisories are likely, possibly even
warning level across interior locations.

Thereafter, temperatures will moderate through early next week
as a frontal system approaches with a strong return SW flow.
Temperatures will likely rise to above freezing both Monday and
Tuesday with chance of precipitation. Initially, there will be a
chance of snow all locations on Monday, but warming aloft will
allow for a transition to rain at the coast and a wintry mix
inland. With the arctic high passing to the south of the region
over the weekend, this will hinder cold air damming along the
lee of the Appalachians.

Models also differ in the timing/overall strength and progression of
the frontal system with a potential frontal wave Monday night into
Tuesday.

&&

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
High pressure slides east of the region into this evening. Low
pressure will deepen off Hatteras tonight, and track east of
Cape Cod on Thursday.

VFR today, then snow develops tonight, with latest guidance
indicating after midnight. Onset timing is currently 6z to 9z. An
earlier onset by a few hours is still possible, as this was
highlighted with tempo groups in the TAFs. Especially for KJFK and
KISP if some of the higher resolution modeling is correct.
Therefore timing adjustments may be needed in subsequent TAFs.

Moderate to heavy snow appears likely for the Thursday morning push,
with visibilities of 1/2SM or less at times, with the 1/4SM
visibilities more likely for KBDR and KISP, with KJFK and KLGA
right on the fence. Snowfall rates around 1 inch per hour at
the NYC airports, with higher rates possible east and lesser
rates at Newburgh anticipated for now.

Storm total snow forecast:

KJFK: 4-6
KLGA: 4-6
KEWR: 3-4
KTEB: 3-4
KHPN: 3-5
KSWF: 2-3
KBDR: 5-8
KISP: 6-10
KGON: 8-12

Snowfall rates and amounts subject to change based on the exact
track of the system.

Light winds, below 10 kt, with variable direction initially,
then going increasingly SW through the day but remaining light.
Winds may briefly go S-SE early this evening before going
becoming northeast just after 00Z, then increase through the
night. A significant increase in the winds can be expected after
12Z Thursday, with gusts in excess of 30 kt at most airports by
around 18Z. Winds will also back to the north during this
period.

&&

.MARINE...
Winds continue to diminish this morning as high pressure
builds, then passes offshore. Expect shifting winds as the high
moves east. Relatively tranquil conditions are forecast through
the day today as seas subside.

However, this will be short lived. Conditions rapidly deteriorate
tonight as low pressure approaches from the south and rapidly
deepens as it does so. This low looks to pass east of the waters
Thursday morning, then well to the northeast late this week.

Winds quickly increase to gale force after midnight tonight from the
northeast. Then winds back to the north/northwest Thursday, with
gales continuing through Friday at a minimum.

For the ocean waters east of Moriches inlet, expect a period of
storm force winds, or gusts up to 50 kt, during the day Thursday. A
few gusts to 50 kt are possible over the extreme eastern portion of
the LI Sound. Storm posted for ANZ350 (ocean waters east of Moriches
Inlet NY), but not for ANZ330 (Eastern LI Sound) at this time.

As mentioned, gales likely continue through Friday and potentially
into Friday night in wake of low pressure with strong caa. SCA
conditions may linger into Sunday on the ocean waters.

&&

.HYDROLOGY...
No significant hydrologic impacts are expected through the week
at this time.

&&

.TIDES/COASTAL FLOODING...
A Coastal Flood Advisory was issued for the Thursday morning
high tide, with locally moderate flooding expected in the Great
South Bay. Tidal departures of 3/4 to 1 1/2 ft are needed for
minor coastal impacts in vulnerable areas.

Timing of windshift of strengthening winds from NE to N will be
critical. A later shift, will increase the potential for minor
coastal flooding.
