Synopsis
A cold front will slowly approach tonight, eventually moving
across Saturday morning into Saturday afternoon. A secondary
cold front moves across Saturday night. High pressure builds to
our southwest Sunday into Monday. A weak cold front will move
through our area later Monday. High pressure builds towards the
mid atlantic coast Tuesday and Wednesday, before moving offshore
Thursday. Unsettled weather return for the end of the week.

Near term until 6 am Saturday morning
The main forecast concern tonight into early Saturday will be the
heavy rain associated with any showers and thunderstorms ahead of an
approaching cold front. More details on this in the hydrology
section but there will essentially be a low chance of flooding
because of the heavy rain potential. This is from the remnant low of
cindy that will be traveling along the cold front and this moves in
by early Saturday. Elevated instability as diagnosed from showalter
indices only slightly negative so have isolated thunderstorm
wording in forecast. Shear further increases with low level jet
tonight as SW winds increase to 45-55 kt between 3 and 4 kft,
so any thunderstorm that develops could be strong with gusty
winds with a marginal threat that thunderstorms could be severe.

Lows tonight were a blend of nam12 gmos and adjusted slightly
higher. Overall, temperatures will not drop much from this
evening through the night. Boundary layer moistens overnight
with patchy fog developing, especially in areas that are outside
the rain showers.

The moderate risk of rip current development continues through
this afternoon, due to building southerly winds waves and a 2
ft long period SE swell.

Short term 6 am Saturday morning through Saturday night
Starting out Saturday morning, the remnant low of cindy with the
showers and thunderstorms will be near to just southwest of the
region. Heavy rain threat remains early in the morning with
patchy fog early especially in areas outside of rain showers.

It moves south of long island Saturday afternoon as the cold
front moves across. The showers and thunderstorms move offshore
in the afternoon as winds become more westerly. Depending on how
fast clouds decrease, the surface temperatures could warm up
quickly. Expecting an above normal day regarding temperatures
with boundary layer mixing giving highs mid to upper 80s most
places with some lower 90s in northeast nj.

For Saturday night, a secondary cold front moves across which will
result in winds becoming more northerly late Saturday night after
its passage. Dry conditions, light winds and continued mostly
clear conditions will result in radiational cooling. A vast
range of lows will be seen in the region from upper 50s in
rural inland sections to lower 70s in parts of nyc from the met
guidance.

A high risk of rip current is likely Saturday with building
southerly swells and wind waves.

Long term Sunday through Friday
Dry conditions expected on Sunday as a ridge of high pressure builds
towards the mid atlantic coast. Expect high temperatures to be in
the low to mid 80s on Sunday. A weak surface cold front will affect
the local area Monday afternoon into Tuesday. The system will not
have a great deal of moisture associated with it, but cooler
temperatures aloft may spark off a shower or t-storm late Monday
into early Tuesday. High temperatures on Monday and Tuesday are
expected to be in the mid to upper 70s to lower 80s.

High pressure continues to build towards the area on Wednesday and
slowly moves offshore on Friday. A few showers are possible Friday
afternoon. Temperatures will start out in the upper 70s to near 80
on Wednesday then slowly increase to mid to upper 80s by Friday.

Aviation 20z Friday through Wednesday
Low pressure tracks through eastern canada this afternoon into
Saturday morning with an associated cold front approaching this
evening and moving through the terminals 12z to 16z Saturday.

Winds will be generally from the southwest 220 true, with gusts to
around 20 kt. Sea breeze influence will keep the winds more
southerly along the coastal areas this afternoon. With the passage
of the cold front winds shift to west to northwest, to the left of
310 true, and become gusty Saturday morning.

GenerallyVFR with occasional MVFR ceilings this afternoon.

Restrictions in fog and showers develops after 06z, isolated to
scattered thunder is possible late this afternoon and this evening.

Another round of showers develops late tonight with the chance of
heavy rain and ifr visibilities.

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.
