What forecasters said that day
The local office's own words before this winter storm 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 winter storm warning went out at Mar 12, 1:42 AM EDT, 1 hour 48 minutes earlier.
Area forecast discussion, Mar 12, 1:42 AM EDT, 1 hour 48 minutes before
Area Forecast Discussion
National Weather Service New York NY
142 AM EDT Mon Mar 12 2018
.SYNOPSIS...
Weak high pressure will be in control of the weather through
the morning. A strong coastal low will impact the area late
Monday through Tuesday. High pressure then slowly returns for
the late week period. A weak frontal system may approach for the
weekend.
&&
.NEAR TERM /UNTIL 6 AM THIS MORNING/...
Minor changes to the forecast based on latest conditions.
Overnight lows were bumped up in some locations.
A weak ridge will keep tranquil conditions tonight, with mainly
clear skies and chilly temperatures.
Lows range from the lower to mid 20s across the interior and
pine barrens with radiational cooling, and lower 30s in and
around NYC.
&&
.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM TUESDAY/...
Dry initially as weak ridge yields to northern stream shortwave
and undercutting short-wave pivoting through the Carolinas
and across the western Atlantic. Models remain well clustered
with coastal low developing and tracking toward or just east of
the 40N/70W benchmark. Latest 12Z ECMWF remains an eastern
outlier per differences noted in shortwave progression.
Snow or a rain/snow mix begins either late afternoon or early
evening. Then a transition to all snow occurs as the low deepens
and tracks northeast toward the benchmark.
Timing for steadiest and heaviest snow appears to be overnight
Monday night into early Tuesday. Snowfall rates of 2 to 3 inches
per hour are quite possible over eastern sections, based on
strong frontogenetic banding. The Tuesday morning commute will
be impacted.
Assuming the track and intensity forecast is correct, a 970 hpa
low near or just east of the benchmark, would expect heaviest
snow and highest accumulations to be placed along the coast,
east of NYC.
Have expanded the Winter Storm Watch from Monday evening
through Tuesday to Long Island (east of NYC) and southern CT,
with highest amounts east. A foot of snow is possible in spots
over SE CT and eastern LI.
Of course any wobble in track NW or SE will result in a change
in amounts.
Advisory level snowfall is possible for the remainder of the
area, western half, for under 6 inches of accumulations.
Temps remain cold, with temps in the 30s to near 30 Monday,
falling into the 20s and lower 30s at night.
As the storm pulls away, NW winds bring in drier air, and
snowfall potential tapers off during the afternoon hours
Tuesday.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...
The region will be under the influence of a polar low and
associated troughing mid to late week. A persistent deep NW
flow will remain through late week as the large and strong
closed low drifting north through Eastern Canada. Models then
diverge on how quickly this troughing transitions to a zonal
upper flow heading into the weekend.
In terms of sensible weather, cyclonic flow will likely maintain
a breezy W/NW flow, diurnal instability cloud cover, scattered
snow showers/flurries and temps near to slightly below
seasonable Wed through Thu.
Models in general agreement with high pressure building towards
the region Friday with fair and seasonable weather. But as
noted earlier, there is some divergence in upper level pattern,
which results in differences in approach of weak shortwave
energy and frontal system for the weekend.
&&
.AVIATION /06Z MONDAY THROUGH FRIDAY/...
High pressure remains in control over the terminals today. Low
pressure then approaches from the south and passes to the
southeast tonight into Tuesday.
VFR through around 00z. Conditions will then gradually lower to
MVFR and then IFR in developing light snow. Snow may become
moderate with LIFR conditions across Long Island and southern
Connecticut terminals after 03z. 1-2 inches of snow accumulation
is possible by 06z Tuesday.
Winds will continue to become NE under 10 kt early this morning.
Winds then veer towards the ENE into the afternoon. Speeds will
increase to 10-15 kt and begin to gust near the coast this
evening. Winds back to the NE tonight with gusts 20-25 kt,
especially near the coast.
.OUTLOOK FOR 06Z TUESDAY THROUGH FRIDAY...
.Monday night-Tuesday...IFR to LIFR in light to moderate snow,
with periods of heavy snow east of city terminal late Monday night
into Tuesday morning. Light snow continues Tuesday morning with
improving conditions in the afternoon. Gusty NE winds 20-25 kt
backing to the NW Tuesday morning.
.Tuesday night-Wednesday...Mainly VFR. Chance for rain/snow
showers Wednesday afternoon. NW winds G25-30 kt.
.Thursday-Friday...VFR. W winds G20-25 kt.
&&
.MARINE...
Sub-SCA conditions expected through Monday morning as high
pressure slowly retreats north and east.
An intense offshore low passing to the south and east late
Monday into Tuesday will likely bring Gale conditions over the
ocean waters and eastern nearshore waters Monday Night into
Tuesday. There is a low potential for Storm conditions for the
eastern ocean waters during this time. To the west, occasional
gale gusts possible.
A gusty SCA to marginal Gale NW flow will likely linger well
into the middle of next week behind the departing storm, with
rough seas continuing on the ocean.
Winds and seas should gradually subside Friday as high pressure
builds towards the waters.
&&
.HYDROLOGY...
There is increasing potential for a moderate to heavy
precipitation event Monday night into Tuesday. No hydrologic
impacts are anticipated, as this would be primarily in the form
of snow.
&&
.TIDES/COASTAL FLOODING...
A coastal storm will bring mainly minor coastal impacts with the
Tuesday morning high tide cycle, along LI Sound and the southern
and eastern bays of LI. Surge of generally 2 1/2 to 3 ft is
needed for minor coastal flooding and 3 to 4 ft for moderate
coastal flooding with the Tuesday morning high tide. Locally
moderate impacts are possible across the vulnerable north shore
of LI and twin forks locales due to wave action on top of
elevated waters.
