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.

A warm front will approach through today and lift into the area
this evening. A cold front follows late tonight into Wednesday
morning. High pressure returns behind the frontal passage and
remains through Saturday. Another frontal system impacts the
area on Sunday and Monday.
Near term until 6 pm this evening
A shortwave trough will track through the great lakes today
with its associated sfc low arriving in western ny state this
evening. Onset of rain is slightly slower than 24 hours ago,
especially the NAM and cmcreg which hold any pcpn off in nyc
until late this aftn. Hi-res models including the hrrr, 3km nam,
and all members of spc's href bring showers in this morning
from W to e. Have compromised on the timing, although leaned
towards the latter (faster) solutions.
Otherwise, an overrunning pattern strengthens this morning with
additional showers overspreading the area. Marginal elevated
instability develops late this aftn N and W and have adjusted
timing of thunder in the grids to confine it mainly to orange
Short term 6 pm this evening through Thursday night
Warm front lifts into the area this eve, but may struggle to
lift through until parent low pressure traversing northern new
england drags it through. There is also the possibility that it
doesn't completely clear the local area before the cold front
catches up to it tonight. Showers continue this eve, but should
become more sct in nature on the south side of the warm front
and also as the cold front moves through. Marginal elevated
instability overnight will allow for the possibility of a few
rumbles of thunder. This could result in a few isold storms with
moderate to heavy rain, especially this eve as pwats MAX out
between 1.5 to 1.75 inches. Have also added fog into the
forecast with the approach passing of the warm front and light
Cold front tracks across the area late tonight and pushes south
of the area Wed morning. A stray shower is possibly from nyc
and points east Wed morning with the front nearby. Skies will|
clear Wed morning with a thermal trough developing and seabreezes
likely Wed aftn as high pressure builds in from the great
Dry weather and above normal temps are expected Wed and thu.
Long term Friday through Monday
The cold front will be moving east of the tri-state area Wednesday
morning, with still a low chance of a shower mainly SE of the lower
hudson valley. Cold air advection behind the front will be weak, and
with a mostly sunny afternoon, high temperatures will be above
normal with most areas ranging from the mid 70s to lower 80s. High
pressure then passes through the region on Thursday and remains in
control on Friday. Dry weather continues both days with highs a
couple degrees above normal on Thursday, and then warming up even
more on Friday.
There remains some uncertainty for the holiday weekend as global
models and ensembles disagree on the surface features that would
impact our weather. Have gone closer to wpc ECMWF depiction of a
cold front dropping down from the north on Saturday and perhaps
stalling over us at some point on Sunday, remaining in the vicinity
into Monday. Chances of showers and thunderstorms will be present
all 3 days, but for now have the overall lowest chances during
Aviation 14z Tuesday through Saturday
A warm front slowly approaches from the southwest through this
afternoon. The warm front lifts into the region this evening
with a cold front moving across late tonight into early
Expect gradually lowering ceilings and rain showers moving in
from west to east going into the afternoon.VFR initially but
conditions lower to MVFR mid to late this afternoon as rain
showers become steadier. Ifr develops by tonight. An isolated
thunderstorm is possible late this afternoon into tonight.
Se winds 5-10 kt will become more easterly and decrease in speed
this afternoon into tonight. Some variability in direction is
expected overnight before a more NW flow of 5-10 kt develops.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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.
