Synopsis
High pressure builds in through Saturday. A deep low passing several
hundred miles west then north of the region will nonetheless produce
unsettled weather across the area Saturday night and Sunday. A
relatively weak system may impact the area during the middle of next
week.

Near term through Saturday
Water vapor indicates a stream of moisture pumping directly into the
area from the subtropical pacific. Because of this, extensive cirrus
is expected thru sat. This cloud cover will be the main limiting
factor for temp drops tngt, with winds becoming lgt and vrb as a
1030s high builds in. A blend of the nbm and met mav was used
tngt, with the nbm otherwise used.

The 00z model suite suggests mainly a dry day on sat. As a result,
the timing of pcpn onset has been slowed in the fcst. Best chc for
rain before dark will be roughly south and west of a line from fire
island inlet to newburgh.

Short term Saturday night through Monday
Rain overspreads the entire area Sat ngt. With dewpoints starting
off in the 20s across the interior and a very weak sfc flow away
from the immediate coasts, some pockets of fzra are very possible
especially the NRN third of the cwa. The fzra has been included in
the fcst, and an advy would be needed if the event unfolds as
currently expected. Elsewhere, including nyc, all rain is expected
attm.

The rain tapers off on Sun from SW to ne. Temps approach 60 in nern
nj as the thermal ridge passes and a brief period of SW sfc flow
develops. The associated cdfnt will pass around the Sun eve time
period, kicking up winds and cooling temps down significantly. A
burst of advy lvl winds are possible behind the front, with the
windy wx continuing on mon. H85 winds around 55 kt in the GFS sun
eve.

Long term Monday night through Thursday
The 00z model data indicates that the long term will remain
generally fair and cool. The nbm with some adjustments was used for
temps. The GFS continues to indicate the passage of a sys around
wed. It looks to be a pacific canadian hybrid. The ECMWF is dry, but
the gem supports the gfs. Chance pops have been maintained in the
fcst, with mainly snow or rasn across the interior, and a better chc
to go over to all rain at the coast.

Aviation 12z Friday through Tuesday
High pressure builds from the great lakes through tonight
resulting inVFR conds.

Nw winds around 10 kt through 22z or so then diminish. Winds
will veer n-ne this evening and overnight.

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.
