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 continues to weaken over the region overnight and will move offshore Wednesday. An area of low pressure approaches Wednesday, passing to our south Wednesday night. Canadian high pressure builds in Thursday through Thursday night, then gradually slides to the northeast Friday into Friday night. A frontal system affects the region Saturday into Sunday. High pressure then builds into the area early next week.

High pressure continues to weaken over the region overnight and
will move offshore Wednesday. An area of low pressure approaches
Wednesday, passing to our south Wednesday night. Canadian high
pressure builds in Thursday through Thursday night, then
gradually slides to the northeast Friday into Friday night. A
frontal system affects the region Saturday into Sunday. High
pressure then builds into the area early next week.
Near term until 6 am Wednesday morning
Clouds increasing from the west as high pressure weakens over
the local region. Light NW flow will become more variable in
direction at times. Weather will remain dry. Min temperatures
were adjusted slightly higher across western sections and kept
nearly the same as before for eastern sections where radiational
cooling has been more effective so far.
Lows should continue to run around normal, generally from the
middle 50s to middle 60s. Min forecast temperatures will be near
70 in and around the nyc metro area.
Short term 6 am Wednesday morning through Wednesday night
High pressure over the region slides east on Wednesday. We are
generally looking at dry conditions on Wednesday, however an
increase in clouds can be expected as an area of low pressure
approaches from the west. There is a low chance for a few
showers west of nyc late in the afternoon.
Wednesday temperatures will climb into the middle and upper
70s, with a few lower 80 degree readings in and around the nyc
Rain will continue to overspread the region Wednesday night, as
low pressure slides south of the region. There are some
differences with the forecast models with respect to the
placement of the low and the amount of precipitation. The 12z
nam was a bit of an outlier with well over an inch of qpf. Sided
more with the 12z gfs ECMWF and wpc guidance, with a general
half to three quarters of an inch across the southern half of
the cwa, with lesser amounts across the lower hudson valley and
southern connecticut. Precipitable waters increase to 1.75 to
around 2" Wednesday night, so there is the potential for locally
heavy rainfall as well. Can not rule out a few rumbles of
thunder as well.
Lows Wednesday night should run a few degrees above normal.
Long term Thursday through Tuesday
Models in general agreement with the upper air pattern through the
period. Mean upper troughing across the NE on thu, will give way to
brief ridging on Friday. The next feature of note will be an upper
low over the central us on Thu fri, eventually shearing NE towards
the region this weekend as a northern stream trough amplifies south
through ontario quebec. A few pieces of energy will work through the
ne, before the upper trough axis swings through early next week.
This appears to be followed by upper ridging.
In terms of sensible weather, tranquil and seasonable late june
conditions expected Thursday Friday as canadian high pressure builds
to the north. Unsettled weather expected Sunday as low pressure
track well to the nw, with a warm front moving through the region
Saturday, and cold front on Sunday. At this point, appears to be a
high shear low CAPE situation with warm frontal prefrontal trough
passage Sat into Sat night, bringing threat of showers and a few
thunderstorms. Brief very warm and humid interlude on Sunday may
allow for a few thunderstorms along the cold front as well.|
Then return to tranquil and seasonable conditions early next week as
canadian high pressure builds from the northwest.
Aviation 03z Wednesday through Sunday
High pressure builds into the region from the north overnight
into Wednesday, moving off the new england coast Wednesday
afternoon. A wave of low pressure approaches from the west
toward 00z Thursday.
Vfr through the forecast.
Winds n-ne under 10 kt, become light and variable outside of
the nyc terminals. Light NE to E winds become southerly
Wednesday morning into midday.
Outlook for 00z Thursday through Sunday
Wednesday night Showers likely with MVFR to ifr conditions.
Thursday MVFR early with showers ending, then becomingVFR.
Saturday A chance of showers, possibly a thunderstorm, sat
into Sat night.
Sunday Vfr expected. Slight chc of a shower.
High pressure building over the waters will keep winds and seas
below SCA levels through fri. Next chance for SCA conditions
may be Sat night into Sun with moderate S SW flow ahead of cold
Dry conditions are forecast tonight into Wednesday morning.
Currently forecasting 1 4 to 3 4 of an inch basin average
rainfall from late Wednesday afternoon through Wednesday night
with the heaviest amounts across NE nj, new york city, and long
island. With very high precipitable waters forecast, there is
the potential for locally heavy rainfall with any stronger
convection. Areas experiencing locally heavy rainfall could
experience minor flooding, mainly of urban and known poor
No significant widespread hydrologic impacts are currently
expected from Thursday into early next week.
Nyc NOAA weather radio station kwo-35 (162.55 mhz) remains off
the air for an extended period of time.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
