Synopsis
A low pressure system approaches passes through into this
evening. A weak cold front approaches from the west Tuesday,
then crosses the area Tuesday night... Followed by another on
Wednesday. High pressure then builds to the south through
Thursday night. Another cold front approaches on Friday then
slowly crosses the area Friday night.

Near term until 6 pm this evening
Two vorticity maximums ahead of a broader upper low to the west
are influencing the development of showers across the area this
morning. Localized brief moderate to heavy rainfall will be
possible as another round moves across nj into portions of
southern ny ct including long island, evident in upstream
observations and given convective appearance on satellite.

Showers gradually taper off from west to east by evening, though
with onshore flow expect a continuation of patchy drizzle and
fog.

Unseasonably cool temperatures today as clouds and rain keep
temperatures in the upper 50s to around 60 for highs, some 10 to
15 degrees below normal.

There is a moderate risk of rip currents for area beaches.

Short term 6 pm this evening through 6 pm Tuesday
Frontal system pushes east of the area tonight, along with the
coastal storm. After some lingering showers early this evening,
conditions should remain dry. However, drizzle and fog may
persist overnight, with low level moisture trapped under an
inversion.

Another front approaches slowly from the west. Chances for rain
increase from west to east during the day Tuesday. Enough
instability for some thunder, but nothing severe expected.

Temperatures continue to be below normal.

Long term Tuesday night through Sunday
The models continue to have differences in how they handle the very
broad closed low that will be over SE canada Tuesday night through
Thursday night. As a result they also differ in the strength and
timing of shortwaves rotating around the base of the low, and hence
on the precise timing of precipitation during this time frame.

However, do have likely pops in for Tuesday night, as the models do
agree there should be some measurable rainfall across the region
then, but do have differences in timing during the night. Lows
Tuesday night should be a few degrees above normal.

For Wednesday and Wednesday night have mainly chance pops across
northern zones and slight chance pops across southern zones. With
showalter indices progged to 0 to -2, also have a slight chance of
thunder in for Wednesday afternoon and evening. Highs Wednesday and
lows Wednesday night should be a few degrees above normal as well.

Zonal flow sets up Thursday and Thursday night, and it appears the
region and with significant shortwaves progged to the NE and NW during
this time frame, have gone with a dry forecast then.

The model differences become even more noticeable Friday-Saturday.

For Friday, do have chance pops throughout by afternoon and continue
through Friday evening (along with a slight chance of thunder). Then
limit pops to slight chance from late Friday night-Saturday morning.

Then go with a dry forecast late Saturday Saturday night as both the
gfs and ECMWF show the core of the closed low to the NE then.

The new ECMWF has joined the 00z GFS in keeping Sunday dry, but
noting it previously had a coastal low approaching (now just
suppressed farther s), do have slight chance pops for Sunday.

Temperatures Thursday through Saturday night will feature near
normal highs and lows a few degrees above normal. Highs Sunday are
currently forecast to be a few degrees below normal.

Aviation 14z Monday through Friday
A weakening frontal system will approach from the west, while
low pressure passes off to the southeast today. The area will
be between the two systems, under an area of weak high
pressure. This will result in widespread clouds and periods of
light rain and or drizzle.

Expect widespread MVFR CIGS through this evening, with local
ifr at khpn. Showers moving in from the west could bring tempo
ifr vsby to the nyc metros toward midday, with thunder chances
nil as instability off to the west weakens. Thereafter could see
tempo ifr CIGS at any time from mid afternoon into the evening,
but the main push for ifr CIGS looks to be after midnight
tonight.

High confidence in E to ene winds 8-15 kt this morning,
diminishing to 10 kt or less this afternoon. Confidence still
only medium at best on wind direction this evening, which could
range anywhere from NW to se, but speeds should be light.

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.
