Synopsis
A cold front will slowly approach and move across this morning
into the afternoon. A secondary cold front moves across
tonight. 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 this morning
Will monitor upstream showers tstms, and with increasing
coverage across our area this morning. Primary threat will be
localized flash flooding in a very tropical air mass as the
remnants of tropical storm cindy move northeastward along an
approaching cold front. In addition, increasing low level jet
and potential backing of low level winds ahead of remnant low
could aid stronger storm development early this morning.

Lows were a blend of nam12 gmos and adjusted slightly higher.

Boundary layer moistens with patchy fog developing, especially
in areas that are outside the rain showers.

Short term 6 am this morning through 6 pm Sunday
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 this 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 using gmos with slight
adjustments.

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 moderate risk of rip currents is forecast for Saturday.

Long term Sunday night 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 06z Saturday through Wednesday
A cold front approaches this evening, then slowly moves through
the terminals by around 12 to 16z tomorrow morning. Initial area
of thunderstorms will gradually decrease in intensity as they
approach the western-most terminals this evening - including the
nyc metro area. Additional showers and thunderstorms are
expected overnight with the approach of the cold front, with
heavy rain and reduced visibility possible at times.

Winds for most of the night will be from the south-southwest
with occasional gusts to around 20 kt possible. A low level jet
will move up the coast, with a brief period of llws possible
primarily at lga jfk isp and to a lesser extent elsewhere.

Following the front tomorrow morning, winds will shift to west-
northwest with increasing gusts through the day and decreasing
cloud cover.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
