Synopsis
High pressure continues to move offshore today, allowing low
pressure to approach from the west, passing just north of the
area tonight. Meanwhile, a developing coastal low will develop
and pass just east of montauk during the day Wednesday, then
moves up the coast into the canadian maritimes Wednesday night.

High pressure will then build to the south through Friday,
moving into the western atlantic this weekend. Low pressure will
then approach from the west early next week.

Near term until 6 pm this evening
High pressure continues to push offshore today. This will allow
weak low pressure and associated cold front to approach from
the west. While 00z forecast model guidance were fairly good
agreement keeping much of the region dry today, have updated
pop based on spotter report on orange county indicating a trace
of new snow on the ground. Most of the light snow today should
be to just the far northwestern portion of the cwa. As such,
have backed up the start time of the winter weather advisory for
portions of nj and the lower hudson valley til 4 pm. Otherwise,
expect cloudy skies today. Temperatures today climb into the
lower and mid 30s, warmer closer to the coast.

Short term 6 pm this evening through 6 pm Wednesday
Winter weather advisories in effect for northeast new jersey,
the lower hudson valley, southern connecticut and the northern
portion of nyc for late this afternoon through Wednesday.

Low pressure and associated cold front approach the western
portion of the CWA tonight, with the low passing just north of
the region. Meanwhile, a second area of low pressure develops
south of long island tonight, and passes east of montauk early
Wednesday afternoon. The combination of these two system will
bring precipitation to the region. Highest confidence for snow
is north and west of nyc, while the potential for mixed p-types
reduces confidence for the city into long island and coastal
connecticut. Expecting the precipitation to remain mostly all
snow through midnight, then as the developing low approaches, it
should bring some warmer air into the area to change
precipitation over to rain or a rain snow mix across much the
long island, nyc and portions of coastal ct. The changing p-type
has made forecasting snowfall amounts somewhat difficult,
especially right along the rain snow line. For now, thinking the
highest snowfall totals will be across the lower hudson valley
and southern ct, with the exception of southern new london
county. These areas have 4-6 inches of snow forecast. Across ne
nj and the northern portions of nyc, looking at 3-4 inches. The
southern portion of nyc and nassau, 2-3 inches are expected. And
across suffolk county on long island, up to 1 inch. The
heaviest precipitation is expected to fall Tuesday night into
Wednesday morning, then taper off from west to east during the
mid to late afternoon and early evening. 16 00z forecast
guidance has come into better agreement with the track of the
low, however a shift to the west, would increase the chance for
more rain across nyc and ct and potentially increase snowfall
amounts across the interior. A track farther offshore, would
increase snowfall amounts closer to the coast.

Lows tonight fall into the middle and upper 20s across the
interior, while coastal locations fall into the lower 30s. On
Wednesday, highs climb into the lower 30s across the interior,
with middle 30s closer to the coast.

Long term Wednesday night through Monday
On the heels of an upper trough passing offshore early Thursday, a
progressive southern branch of the polar jet will become dominant
across the lower 48, with a a gradual warmup as the air mass
transitions to pacific origin. Daytime highs on Thursday will be or
just above near freezing, rising to the upper 40s and lower 50s by
Sunday Monday.

Conditions will be mainly dry as a large area of high pressure over
the lower mississippi valley translates slowly east and passes to
the south through the week and offshore this weekend.

A southern branch storm system then approaches late in the weekend
into early next week, with a surface low forecast to track up into
the great lakes. The trailing cold front moves through Monday night.

This is likely to be a rain event with a deep layered southerly flow
preceding the system, but with cold sfc air initially there could be
some mixed precip inland late Sunday night Monday morning inland nw
of nyc.

Aviation 12z Tuesday through Saturday
High pressure retreats to the northeast today. An area of low
pressure approaches from the south into tonight, then tracks to
near CAPE cod by early Wednesday afternoon.

Mainly MVFR, except some low endVFR ceilings at kgon to today,
with conditions becoming MVFR there by 23z. Conditions should
then become ifr at all terminals after midnight.

Spotty snow showers are possible at NW terminals this morning.

Otherwise, expect any precipitation to hold off until after
sunset, except at kswf where could see some light snow in the
afternoon. Expect all snow at lower hudson valley and nj
terminals and kbdr. Will see a snow rain mix, possibly changing
to all rain at kgon kisp and possibly rain mixing in with the
snow at klga and kjfk overnight.

There is a chance that kisp and kgon and a low chance that klga
and kjfk could change completely to rain overnight Wednesday
morning, but the confidence in this is too low to reflect in
the tafs at this time.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
