Marine Weather and Tides
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis for the long island waters and new york harbor.. High pressure remains offshore in the atlantic through Monday. A cold front approaches from the north Monday night, then crosses the area early Tuesday. Weak high pressure builds in from the northwest thereafter into midweek. Outside of a reinforcing cold front Wednesday night, high pressure will remain across the region through Friday night.

259 am edt Mon jun 18 2018
Offshore high pressure remains through Monday. A cold front will
approach from the north Monday and move across early Tuesday.
Weak high pressure builds in Tuesday afternoon into midweek.
Outside of a reinforcing cold front Wednesday night, high
pressure will remain across the region through Saturday. A
frontal system then approaches Saturday night into Sunday.
Near term until 6 am this morning
The forecast remains on track. Cirrus will continue to spill
over the large ridge centered across the southeast us through
High pressure will be offshore in the atlantic. There will be
s-sw flow, allowing for warmer and more humid conditions. Used a
combination of mav and ecs for the lows, ranging from near 70
in nyc to lower 60s in some parts of the interior, se
connecticut and eastern long island.
Short term 6 am this morning through 6 pm Tuesday
The mid level and upper levels have nearly zonal flow that remains
but there will be some progression eastward as the base of the
ridge moves farther east in the southeast us. There will be a
mid and upper level trough making its way into quebec.
The mid and upper level trough moves across northern new england
Monday night into early Tuesday. The trough begins to lift
northeast of the region Tuesday afternoon.
At the surface, low pressure moves eastward just north of maine
Monday, moving into the canadian maritimes Monday night. This
will bring a cold front that will approach the region from the
north Monday night. The front moves across the region early
Tuesday. Weak high pressure builds in from the north behind the
For Monday, hot and humid conditions with highest combination
across the lower hudson valley and northeast nj. Just high
enough temperatures and dewpoints across northeast nj and the
lower hudson valley to make for heat indices near 100.
Elsewhere, expecting heat indices in the mid to upper 90s for
nyc (mostly 95 to 97) and in the 90s for southern connecticut
and nassau into western suffolk. Lower heat indices are expected
farther east. Actual high temperatures are in the mid 90s across
parts of northeast nj and the lower hudson valley and with
moisture advection and pooling of dewpoints near the hudson
river, that is why the heat indices are a few degrees higher for
these locations. Actual highs for nyc are in the lower 90s with
dewpoints more in the upper 60s.
The highs forecast on Monday are a combination of the 00z ecs
and the previous forecast, going a little above the mav and met
Rain returns to the forecast in the form of showers and
thunderstorms late Monday afternoon through Monday night. These
will taper off early Tuesday. These could produce locally heavy
rain and gusty winds, but the severe threat looks to be limited
to locations farther north of the region, where more wind shear
will exist with lower heights and closer to the base of the
upper level trough.
Went for warmer lows Monday night (mainly in the 70s) as
airmass remains very warm and humid with showers and
thunderstorms across parts of the region. Some model differences
on whether this moves across as a MCS or a weakened one. The
lows Monday night were from a combination of mav met ecs.
Expecting another warm but drier day Tuesday behind the front.
Went with warmer combination of mav ecs for highs, mid 80s to
There is a moderate rip current risk for Monday.
Long term Tuesday night through Sunday
Models have continued to trend toward a drier forecast with
mainly seasonable temperatures. There had been concern with the|
proximity of a frontal system stalling close enough to the area
for potential wet weather toward the end of the week. However,
a northern branch upper trough drops southeast across eastern
canada and into the northeast for the midweek period, lifting
out toward the end of the week into the weekend. A southern
branch shortwave trough approaches for the second half of next
At the surface, high pressure prevails across the region through
much of the period, until a frontal system approaches Saturday
night into Sunday.
Aviation 07z Monday through Friday
High pressure to the south will give way to an approaching cold
front tonight. Widely scattered tstms with brief MVFR ifr vsby
and gusty winds are possible with a pre-frontal trough late
today and early this evening, most likely from about 21z-23z at
kswf, 22z-01z at the nyc metro terminals and khpn, and 00z-02z
at kisp. Since the expected coverage is scattered at most and
not guaranteed to have direct terminal impacts, have mentioned
via vcts rather than prob30 tempo. This could change with later
issuances as confidence in timing and coverage increase.
An additional round of showers tstms with the front itself
expected toward the very end of the 24-hr period and beyond.
Sw flow will increase today, with during Monday with sustained
winds 10-15 kt and gusts around 20 kt from about 18z-24z.
Outlook for 06z Tuesday through Friday
Late tonight Chance of MVFR or lower conditions and locally
gusty winds in showers and thunderstorms.
Tuesday Sight chance of an early morning shower with MVFR
vsby, otherwiseVFR. NW winds (right of 310 magnetic) 15g20kt.
Tuesday night-Wednesday Vfr.
Wednesday night Chance of showers and possibly a tstm, with
MVFR or lower conds, as low pressure passes to the south.
Weak high pressure based offshore, will keep a weak pressure
gradient and conditions below SCA for tonight into early Monday.
Winds and seas increase ahead of a cold front Monday afternoon
into Monday night, but forecast has conditions staying mainly below
sca outside of some brief 25kt gusts on the ocean. The sub-sca
conditions remain on Tuesday.
High pressure prevails Wednesday through Friday with winds 10
kt or less and seas 2 ft or less.
Showers and thunderstorms late Monday through early Tuesday
could result in locally heavy rain. The precipitable water value
of the airmass is forecast to reach near 2 inches. Locally minor
flooding is possible.
Nyc NOAA weather radio station kwo-35 (162.55 mhz) remains off
the air for an extended period of time.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
