Area forecast discussion 
National Weather Service New York New York
713 am EST Tuesday Jan 27 2015

Synopsis...
the strong Nor'easter will slowly pull away today. High pressure
will build in for Wednesday and then move east on Thursday.
Low pressure will track across New England on Friday...followed by
high pressure for much of the weekend. Low pressure may affect the
region late Sunday into Monday.

&&

Near term /until 6 PM this evening/...
hazards and snow amts have been adjusted based on current
conds/trends. Blizzard conds...with heavy snow and strong north-NE
winds...have shifted into eastern Long Island/CT...and blizzard
warnings continue for Suffolk County on Long Island...also for
most of southern CT east of Bridgeport. Snowfall rates of 3-4
inches/hour are occurring with the most intense banding...which is
now mainly over New London County CT and The Forks of Long
Island...and should be slow to pull out this morning while slowly
weakening as mentioned in the previous discussion. The Blizzard
Warning area should see accums close to 2 feet...and possibly
upwards of 30 inches in spots.

Light to locally moderate snow continues farther west...and so
blizzard warnings have been replaced with winter storm warnings.
May drop warnings in NYC...NE New Jersey and the lower Hudson Valley with
the next update if the snow continues to wind down. Even after
snow ends...northwest winds gusting over 30 miles per hour will still lead to
blowing snow...which could cover roads that have already been
cleared and cause additional travel headaches.

Highs will be in the 20s.

&&

Short term /6 PM this evening through 6 PM Wednesday/...
the low slowly fills as it tracks over the Gulf of Maine.
Accumulating snow is essentially over with just some light amounts
over eastern sections. Lows tonight will range from the upper
single digits across interior snow CT...to the teens elsewhere.

Sun returns for Wednesday...with highs in the 20s to near 30.

&&

Long term /Wednesday night through Monday/...
some significant changes here on the extended. This includes
temperatures on Friday as well as Sunday night into Monday...and
the potential for storm Sunday night.

Very cold for Wednesday night as high pressure settles over the
region. Do not expect the influx of warm air advection aloft cirrus until after
midnight.

Clouds thicken on Thursday with warm air advection aloft continuing as heights
build ahead of the short wave.

Expect the light snow Thursday night as the clipper pass approaches.
The clipper's cold front passes early Friday as seen in the sref
and the deterministic models. The clipper moves across New
England before intensifying over the Gulf of Maine on Friday
night. Generally around an inch or so - though temperatures overnight
into Friday morning may rise to or slightly above freezing along
the coast.

Strong cold advection on Friday supports falling temperatures though the
20s and into the teens with a few flurries.

Lots of uncertainty by late Sunday...but have warmed temperatures up
significantly as 00z European model (ecmwf) and GFS both indicate southern stream
low pressure passing across the region and not off the coast. Thus
mixed p-type for the coast. Would expect the potential for a lot
of changes at the forecast evolves with this...but believe this
could end up being a "warm" storm.

&&

Aviation /12z Tuesday through Saturday/...
MVFR to IFR or lower conditions this morning in areas of snow and
blowing snow. North winds back to north-northwest by late this
morning. Gusts 30-40kt...diminishing somewhat late in the afternoon.
Heaviest snowfall expected at kisp and kgon...with rates of 1-3 inch
per hour. These high rates are expected through 15z. Lighter snow
expected for the NYC terminals.

Snow begins to taper in the late afternoon and evening along with
diminishing winds and improving flight categories.

New York metropolitan enhanced aviation weather support...

Marine...
970s low will produce gale to storm force conds today. Winds will
diminish to Small Craft Advisory levels tonight. Seas 16 to 22 feet on the ocean and 4
to 8 feet on the sound.

Conds will become sub-advisory by Wednesday evening as the storm continues
to pull away and high pressure builds from the west. The high will keep
tranquil conds on the waters through Thursday night as the high moves
ohd and then offshore. Gales are likely as low pressure deepens
over the Gulf of Maine late Friday and strong high pressure builds
from the west. Winds gradually diminish on Saturday.

&&

Hydrology...
liquid equivalent amounts should range from 1/2 to 1 inch west of
the Hudson...to 1-2 inches for NYC and western Long Island/CT...to 2-3
inches eastern Long Island/CT.

Low pressure late Sunday into Monday may be bring upwards of an
inch or more of liquid equivalent. At this time...it appears that
the system could be at least partially rain for the coast.

Ice on the Wallkill and Yantic rivers is causing minor
fluctuations in river levels at this time.

&&

Tides/coastal flooding...
seas are up to 5 feet on the central sound and near 10 feet 4 nm
south of Fire Island.
