Synopsis
Low pressure departs overnight. A series of weak low pressure
and frontal systems will pass through the area this weekend
through mid week.

Near term until 6 am Saturday morning
Back edge of accumulating snow will push east of E LI SE ct
through around 11 pm.

Generally 1 to 2 inches have fallen across the nyc nj metro,
westchester and SW coastal ct, with 2 to 3 inches across nassau
and suffolk counties.

An additional 1 2 to 1 inch possible for extreme SE ct and e
suffolk before coming to an end.

Otherwise... Vigorous shortwave pivots east overnight with low
pressure departing out to sea. Clearing and increasing winds
are expected overnight as the pressure gradient tightens
between the strengthening departing low, and strong high
pressure over the SE us.

Another chilly night with lows in the ranging from upper teens
well inland to mid 20s at the coast.

Short term 6 am Saturday morning through Saturday night
Polar upper low pivots southeast into new england on Sat and
offshore Saturday night. Wnw CAA low flow over the great lakes,
accompanied by shortwave lift and left front of 150 kt jet
streak, should be enough to extend light snow shower activity
into the region later Sat morning through Sat afternoon. A
dusting is possible in spots, particularly NW hills.

Otherwise, breezy and chilly on Sat with abundant cloud cover
and glancing caa. Temps will likely hold in the lower to mid 30s
for much of the region, with windchills in the 20s.

Shortwave slides east Sat night, with high pressure building in
from the west. This will have snow showers tapering from W to e
early in the evening, with potential for good radiational
cooling conds for outlying areas later Sat night. Temps should
fall into the teens for outlying areas, with mid-upper 20s for
urban centers.

Long term Sunday through Friday
Models in good agreement with a fairly progressive upper
pattern in place through this period, with a series of weak
frontal systems moving through the region Sunday night through
midweek as a muted northern stream longwave trough slides from
the great lakes into the northeast.

First system of note will be Sunday night into Monday as the
closed low currently over baja mexico, shears towards the ne
ahead of a developing western us trough. Models differing in
the strength of this energy and amounts of moisture drawn
northward, but potential exists for a light precip event Sunday
night into Monday morning. Thermal profiles suggest a start as
snow or wintry mix, transitioning to rain for nyc li, but
potentially remaining a wintry mix for the interior into Monday
morning. Too early for specific details on this light precip
event, but potential exists for hazardous travel conditions
n&nw of nyc LI for Monday morning commute.

Thereafter, models in fairly good agreement with the broad bu
shallow northern stream trough approaching the region on
Tuesday and sliding through during the midweek. At the surface,
the primary low pressure system rides through quebec ontario
with trailing cold front approaching the region Tuesday night.

Overall, appears to be mainly a light QPF event for the Monday
night into Tuesday evening period, due to limited interaction
between northern and southern stream. Thermal profile suggests
precip would be mainly liquid, but could be dealing with
freezing rain across interior Monday night as cold air
typically has a tough time scouring our in this setup.

Upper trough swings through the NE Tue night into Wed with a
glancing shot of modifying arctic air in the wake of the cold
front for Wed thu.

Upper flow flattens and even becomes a bit ridged for Thursday
ahead of the next northern stream trough digging into the upper
plains, which should allow for a moderation in temps ahead of
next potential frontal system.

Aviation 02z Saturday through Wednesday
Low pressure quickly passes to the east overnight as it
deepens.

Any lingering MVFR or ifr conditions eastern terminals (kisp,
kgon) will quickly improve as the snow departs before 4 or 5z.

Otherwise,VFR has returned and skies clear overnight. Expect
increasing clouds during the day Saturday. Ceilings between 3-5
kft expected from late morning through the afternoon. Local
MVFR or ifr conditions cannot be ruled out in snow showers.

Westerly winds 5 to 10 kt increase overnight. Occasional gusts
to around 20 kt are possible overnight, otherwise speeds remain
10 to 15 kt.

Westerly winds increase Saturday after 13-15z, with speeds 15 to 20
kt and gusts 20 to 30 kt.

Outlook for 00z Sunday through Wednesday
Sat night Vfr.

Sun Vfr during the day. Chance MVFR in a mix of -ra -sn towards
midnight.

Mon Low chance MVFR in -ra for coastal terminals, light wintry
mix inland. Improvement as the day progresses.

Tue MVFR possible with a slight chance of showers.

Wed Vfr. NW winds g20-30kt

Marine
The pressure gradient will continue to tighten overnight as low
pres passes S and E of the waters. SCA conds are expected to
develop tonight and continue through sat, with the potential for
occasional gale force gusts on mainly the ocean waters late
tonight through Saturday morning.

Winds and waves diminish below SCA Saturday night as high
pressure builds in.

Next chance for SCA conditions possibly as early as late
Tuesday Tue eve ahead of approaching cold front, but higher
likelihood of widespread SCA Tuesday night through Wednesday
night with tight pressure gradient and strong CAA in wake of
cold front. Gales are possible during this time frame.

Hydrology
No significant hydrologic impacts expected.

Nyc NOAA weather radio station kwo-35 (162.55 mhz) is off the
air for an extended period of 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.
