High pressure building across quebec on Monday will reach the
maritimes Monday night, allowing a warm front to approach the tri-
state region from the south. The warm front slowly moves
northward through the area Tuesday into Tuesday night,
followed by a cold frontal passage Wednesday night. High
pressure then builds to the north through late week, while a
series of weak lows move along a stalled frontal boundary to the
south of the area. A stronger area of high pressure builds from
the west through the weekend.
Near term until 6 am Monday morning
Mid lvl front remains just S of the cwa, with light rain and
sprinkles confined to the ocean S of LI as a result. This frontal
zone will be suppressed swd tngt as the pres rises across the area.
Stlt shows extensive cloud cover to the oh valley. Only gradual
erosion from the N is expected. This presents a temp fcst problem
for tngt, as much of the modeling is showing mainly clr skies late
tngt. Based on the current stlt pics and trends, it seems this may
be too quick. Nevertheless, clearing could still take place within
an hour or two of sunset, allowing for a quick but significant drop
in temps. Because of this, the coldest blend of MOS has not been
used, but the warmest nbm and raw consensus was not used either. The
superblend was in the middle, and was used for the fcst.
There is a low rip current risk thru this eve.
Short term 6 am Monday morning through Monday night
A strong high approaching 1040 will be INVOF quebec city Mon mrng.
The influence of the high will keep the CWA dry for most if not all
of the day. A second shot of thick cirrus, as well as some low
clouds advecting in on increasing ely flow, should produce a mostly
cloudy late mrng and aftn. Mid lvl moisture transport increases mon
ngt, with a theta-e ridge building in rapidly. This will result in
rain developing and spreading nwd across the CWA late Mon and mon
The pres gradient will be increasing due to the strong high to the n
and the approaching warm front to the s. Winds will respond, with
increasing flow thru the day and ngt. Gusts to 30 mph can be
expected, particularly along the coasts, from late in the day thru
A blend of the guidance was used for temps.
There is a high rip current risk on mon.
Long term Tuesday through Sunday
The main concern for the extended will be the potential for heavy
rainfall, especially Tuesday with the warm frontal passage as
instability begins to increase, aiding in the potential for
convective downpours. With antecedent high pressure centered
offshore, there will be a prolonged period for moisture advection,
both from atlantic and gulf regions as wind profiles veer with
height. Pwat values will quickly increase with the warm frontal
passage to around 1.75-2.00 inch, which per SPC sounding climatology
is close to maximum values for time of year. The best chance for any
heavy rainfall will be with and following the warm frontal passage,
particularly as instability increases across the area. Additionally,
despite warm temperatures aloft, there will be instability
concentrated below roughly 500 mb, and with strong veering winds
with height as the front moves through (0-3km SRH around 200-350
m2 s2), there will be potential for brief low topped supercells
capable of damaging winds.
Rainfall may become more periodic into Tuesday night and Wednesday
in the warm sector as broad height falls and cooling temperatures
aloft increase deep layer instability across the area. At the
moment, SPC has much of our forecast area in a 15% outlook for
severe wind potential due to the low CAPE but high shear
environment. The greatest potential for any severe weather and, once
again heavy rainfall will be Wednesday night as a short wave and
attendant cold front move through. However, broad southwest flow
aloft will remain as a western atlantic high begins to retrograde,
and a phased upper low lingers across central canada into the great
lakes. As a result, the forward progression of the cold front will
significantly slow, with the front expected to stall across the
south and potential for us to remain in a humid and somewhat
unsettled period into at least Thursday.
By late week, flow aloft becomes more northwesterly, with increasing
confluence allowing a surface high to strengthen and build into the
area for the weekend, with a return to a cooler and much drier fall-
like air mass.
High temperatures in general will be within a few degrees of
climatological normals with the exception of Wednesday as we remain
in the warm sector following the warm frontal passage. Low
temperatures initially will be 10 to 15 degrees above normal, before|
returning to within around 5 degrees above normal for late week with
the passage of the cold front.
Aviation 20z Sunday through Friday
A frontal boundary will remain near stationary across the mid
atlantic states through Monday, while canadian high pressure
gradually build into new england. A frontal system will approach
Main light rain shield will continue to be suppressed south of
nyc long island the next 24 hours, but a weak convergence zone
along the south shore of LI will bring some MVFR conds (low prob
of ifr) in light rain mist to jfk into early evening push. This
could perhaps spread to kewr klga.
Otherwise... MVFR CIGS across nyc nj metro and LI terminals expected
into evening push, while northern terminals vary between sct-bkn.
Moderate confidence in cig forecast through evening push.VFR cigs
expected tonight, with redevelopment of MVFR CIGS likely late sun
morning into Sunday afternoon.
E NE winds below 10 kt, strengthening to 10 to 15 kt during
morning push. E NE winds of 15 to 20 kt with gusts to 25 kt
likely developing Monday morning for coastal terminals.
Outlook for 18z Monday through Friday
Monday afternoon Pockets of MVFR likely. E wind gusts of
Monday night-Tuesday Periods of rain showers with ifr or
lower. E wind gusts of 25-30 kt, becoming SE tue.
Tuesday night-Wednesday Showers and isolated tstms possible
with MVFR or lower at times. Southerly winds.
Friday MVFR with rain possible.
Winds and seas will remain blw SCA lvls tngt, then increase to solid
sca lvls Mon and Mon ngt. Winds remain strong from the east
then southeast as a warm front passes through the waters on
Tuesday. At least SCA conditions will exist on all waters, with
the potential for gale-force gusts on the ocean waters early in
the day. Winds gradually decrease into Wednesday, though a few
gusts to near sca-levels will remain possible before the cold
frontal passage Wednesday night. Even though winds decrease
further into Thursday, ocean seas will remain elevated before
gradually falling below SCA levels Thursday night into Friday as
the pressure gradient relaxes.
No hydrologic impacts are expected thru mon. A frontal system
will bring locally heavy rainfall and the potential for
localized flooding Monday night into Wednesday night. At the
moment, the greatest potential for any impacts is expected to be
Tuesday with the warm frontal passage. Storm total
accumulations are expected to range from around an inch to three
inches over the course of three days.
Tides coastal flooding
Minor coastal flooding possible during the times of high tide
Monday night and Tuesday morning in response to a strengthening
easterly flow ahead of an approaching low pressure system.
Surges of around 1 1 2 to 1 3 4 ft, and locally up to 2 1 4 ft,
are needed for minor flooding.
Nyc NOAA weather radio station kwo-35 (162.55 mhz) remains 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.
