Synopsis
A trough of low pressure passes through late tonight with high
pressure building in briefly on Monday. Low pressure then tracks
across the great lakes Monday night, sending a warm front across
part of the area Tuesday morning, then followed by a strong cold
front in the afternoon. Intensifying low pressure will move
from the new england coast into the canadian maritimes from
Tuesday night into Wednesday night, then slowly loosen its grip
on the area on Thursday as weak high pressure slides across. An
alberta clipper low will pass to the south on Thursday, then
another low will develop just off the coast late Friday into
Friday night.

Near term until 6 am Monday morning
A shortwave and upper trough axis approach from the west tonight
with a low pressure trough at the surface. The best combination of
lift and moisture arrive after midnight with isolated to scattered
snow showers. Lows around 30 across the city and adjacent suburbs
with 20s for the rest of the tri-state area.

Short term 6 am Monday morning through Tuesday
High pressure briefly builds in behind the departing trough Monday
morning with a lingering snow shower still possible east of the
city. Partly to mostly sunny in the morning, then higher-level
clouds begin to increase in the afternoon. High temperatures will be
a few degrees below normal.

Low pressure moves across the great lakes Monday night. An
associated warm front approaches us with increasing chances of pcpn
late at night, more likely NW of the city. A digging upper trough
and the low center then approach us during Tuesday. Associated
deeper moisture and lift bring then likelihood of pcpn across the
most of the rest of the area during the morning. The low passes us
to the north before exiting during the afternoon with maybe a
secondary low center moving through the tri-state area. Expect pcpn
chances to diminish in the afternoon with the best lift and moisture
exiting. A cold front then follows shortly thereafter, so pcpn
chances will continue through the day.

Warm advection ahead of the main portion of the storm will make this
a mixed pcpn event. Primarily rain is expected for the city,
adjacent suburbs and coastal section, although some snow can mix in
at first. Farther inland, snow or a snow rain mix changes over to
rain by noon on Tuesday. Only perhaps the elevated sections of
western orange county could see an all-snow event. Snow
accumulations expected to be 1 or two inches for the northern
suburbs with perhaps 3 inches in some spots across orange county.

Less than inch is expected anywhere else where snow manages to
accumulate. Highs in the 40s expected for most spots on Tuesday with
even some 50 degree readings for long island.

Long term Tuesday night through Sunday
At the start of the period, blustery and cold weather expected from
Tuesday night into Thursday as intensifying surface low pressure
moves from the eastern new england coast up into the maritimes. The
parent upper low trough will be closing off and becoming negatively
tilted during this time, and a strong vort MAX rotating around the
upper low may help spark a few snow showers late Tue night into wed
morning, especially out east. Blustery conditions expected as the
pressure gradient tightens up on the back side of the low, with
sustained winds 25-35 mph and gusts 45-50 mph possible Wed into wed
night. With temps falling to the teens and lower 20s Wed night, wind
chills should fall to 0 to 5 below well inland, and to the single
digits in nyc metro and along the coast. High temps both Wed thu
should range from the mid 20s to lower 30s.

Ecmwf has been more consistent than the GFS in the longer term
beyond Wed night and was followed for the most part. A weak alberta
clipper low should pass just south on Thu as an associated mid level
impulse passes just south, then another low should develop close by
late Friday as a more significant negatively-tilted upper trough
swings through, that could bring a period of light snow fri
afternoon evening.

Upper level flow after passage of the upper trough on Friday should
become zonal, with moderating temps, rising to the upper 30s lower
40s on sat, and into the 40s on Sunday. A surface low passing well
to the north may manage to produce a few sprinkles showers of snow
or rain late Sat night into Sunday in the low level warm advection
to its southeast.

Aviation 00z Monday through Friday
A cold front will approach tonight and pass on Monday.

Vfr through 6z, then ceilings drop to around 3000 ft with snow
showers in the area into the morning. Ceilings improve toVFR
after 15z, withVFR through the remainder of the TAF period.

Generally westerly winds through the TAF period. Direction will
be just south of west until the frontal passage on Monday, then
will become just north of west. Occasional gusts tonight, then
more frequent gusts to 20 kt on Monday. Gusts will end after
23z.

Outlook for 00z Tuesday through Thursday
Monday night-Tuesday MVFR or lower expected after 6z with a
wintry mix to rain at northern terminals and rain at southern
terminals. Conditions improve toVFR Tuesday afternoon. Se-sw
winds g15-25kt possible.

Tuesday night-Wednesday MainlyVFR, with a chance of MVFR in snow
showers. W-nw winds g20-35kt probable.

Wednesday night-Thursday night Vfr. W-sw winds g15-25kt possible.

Friday MVFR possible with snow. W-nw winds g15-20kt possible.

Marine
Sca conditions expected on the ocean waters through Monday
with winds and seas meeting criteria. Did not have enough
confidence to remove the SCA over the eastern sound and bays.

Looks like a marginal event, but have decided to let the
advisory continue through tonight. Winds and seas subside below
criteria Monday night. Winds and seas then increase during
Tuesday with SCA conds becoming likely on some of the waters.

As intensifying low pressure pulls away, gales should develop on the
ocean Tue night, with SCA conds on the remaining waters. NW gales
expected on all waters Wed night into Thu with a tight pressure
gradient and strong cold air advection. SCA conds may linger into
thu, then quiet conditions expected Thu night into fri, though winds
and seas in westerly flow after the passage of a weak low Fri night
could flirt once again with SCA levels.

Hydrology
No significant hydrologic impacts expected.

Equipment
Nyc NOAA weather radio station kwo-35 (162.55 mhz) is off the
air for an extended period of time. See our headline news on
the web at: http: weather.Gov nyc

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.
