Synopsis
The storm system that brought the season's first widespread
heavy snow will move off to our northeast today. Weak high
pressure will bring drier conditions to most areas through
Saturday. A cold front is likely to push southeast across the
state early Sunday, then high pressure will build over the
region early next week.

Near term through tonight
The season's first major winter storm will continue to wind down
early today. It definitely overachieved with regards to snow as
the marginal warm air that we expected to play more of a role in
allowing sleet and freezing rain to keep amounts down proved
too marginal to bring the expected change-over until after heavy
snow amounts were observed.

Meso-anal shows a surface low just south of islip long island as
of 6am. Satellite shows the upper low rotating through
northeastern pa with a weak shortwave ridge building over pa
behind it. Radar has little left but scattered very light
returns, and remaining surface obs actually showing snow
indicate it is also very light and not accumulating.

In the wake of the departing storm we expect a blustery wsw
flow to develop. This will help maintain clouds and scattered
snow showers over the usual locations of the west and north, but
additional accumulating snow will be on the order of a dusting
to an inch in some spots. Downsloping flow should yield partly
to mostly sunny skies across the southeast half of the forecast
area.

Highs today will be on the chilly side ranging from the mid 30s
over the NW to lower 40s over the se. While well below normal
for mid november, we shouldn't have problems with a rapid
freeze up in areas that saw the wintry mix.

Strong subsidence behind the upper low will cause light winds
to kick up a bit towards dawn as stronger flow aloft mixes to
the surface. Bufkit soundings support gusts as high as 25kts
over the laurels, perhaps high enough to cause a bit of
blowing drifting in open areas.

The overnight will remain gusty with western and northern areas
being cloudy and snow-showery. Minor additional accums of an
inch or less are expected.

Short term Saturday
Broad cyclonic flow aloft will maintain the most clouds and the
highest chances for snow showers over the western and northern
higher elevations. Snow shower activity may be enhanced over the
nw later Saturday afternoon as a weak cold front drops south
through the eastern gr lakes. The W or wsw low level flow will
keep the best over-lake trajectories mainly north of the area.

Highs will be virtually identical to today with highs from the
mid 30s to lower 40s nw-se.

Long term Saturday night through Thursday
A broad upper level long-wave trough will persist over eastern
half of the country through the medium range.

Models hint at a couple of chances for additional snowfall as
disturbances rotate through the fast upper flow. The first
looks like a weak alberta clipper Sunday into Sunday night.

These moisture starved systems most often favor nuisance
although fairly widespread snow amounts. At this time I have
light amounts confined over about the northern half of the cwa.

Another weak moisture starved cold front is advertised for
Tuesday with the best chances for some light snow mainly over
the far north.

Fair and chilly weather will set in behind the cold front and
continue through the holiday and the end of the week.

Aviation 12z Friday through Tuesday
12z tafs sent.

Storm system near the southeast coast of new jersey will move
away for the area today.

Most areas will quickly have improving conditions, except
for the higher terrain areas like bfd and jst. Some snow
showers will linger at times at bfd and jst, as the upper
level trough moves across the region.

It will be windy until early this evening.

Outlook
Sat-sun... MainlyVFR. MVFR with snow showers nw.

Mon... No sig wx.

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.
