Marine Weather and Tides
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

High pressure will begin to build eastward into the region tonight
and move over the region Thursday and Friday. This will be followed
by a cold frontal passage on Saturday. Another area of high pressure
will build into the region for the early part of next week.
Near term until 6 am Thursday morning
1150a and 1230 pm estf: our new 330 pm office guidance has been
issued with the 1150 am and 1230 pm estf updates. There may
be some minor modifications at 330 pm.
This afternoon... Raised temps a bit per obs and added 5mph to
the gusts (generally 25-35 mph range). Showers now ending nj
coast. Cold air advection developing nicely. Considerable
cloudiness parts of NE pa and NW nj but otherwise partly to
mostly sunny elsewhere, except becoming mostly sunny along the
Tonight... Mostly clear with diminishing gusts... Tho still a
breeze in the urban centers and along the coasts where boundary
layer instability is greater with the decent cold air advection.
Lows 4 to 8 degrees below normal.
This forecast was a 50 50 blend of the 12z 22 GFS nam mos.
Short term 6 am Thursday morning through 6 pm Thursday
Sunny with spotty high cloudiness early in the day and then a
general deck of WAA mid or high clouds arriving from the west
northwest late in the day reaching to near i-95 around 6 pm.
Light northwest to west wind. Mixing doesn't look too good so a
fairly chilly thanksgiving day. Highs 6 to 9 degrees below
This forecast was a 50 50 blend of the 12z 22 GFS nam mos.
Long term Thursday night through Wednesday
Thursday night through Friday night:
high pressure will be in place during this period with mostly sunny
skies. Temperatures will warm into the 50's Friday after starting
out in the 20's and 30's. Friday night has trended warmer with
the past few model runs. Light winds will shift to southerly
and increase slightly ahead of an approaching cold front with
lows generally in the 30's and low 40's.
Saturday and Saturday night:
a cold frontal boundary will move through the area on Saturday.
Overall, timing has sped up a few hours on average with the modeling
and ensembles. Enough lift and moisture should be present for a few
spotty rain showers, primarily in the afternoon hours. Temperatures
Saturday morning may be close enough to freezing in the southern
poconos and NW nj for a freezing rain concern. Right now any
precipitation is expected to hold off till mid-morning when it warms
well above freezing. Precipitation looks very light, only a few
hundredths and this forecast used a SREF wpc blend. A few southerly
wind gusts in the afternoon around 15 mph are possible before the
frontal passage. Northwest flow on the backside of the front could
also kick off some sprinkles and flurries toward sunrise Sunday
that could be enhanced where the elevation is highest (southern
poconos and NW nj).
The 12z 11 22 NAM was discounted given a NW bias tendency in the
medium range with low pressure systems. Ensemble guidance continues
to show a low pressure will track from the carolinas northeast
out to sea with little to no influence in our area.
Sunday through Wednesday:
a fairly strong push of cold air advection will occur behind the
front. This will lead to another period of more winter like
temperatures across the region with stronger northwest winds,
gusting perhaps to 25 mph on Sunday. The northwest flow may also
allow for some moisture to transport southeast off of the great
lakes. The moisture could be enhanced by the higher terrain. Highs
Sunday and Monday will generally be in the 40's with overnight lows
will be in the 20's and 30's. Conditions are expected to clear
later Sunday and Monday as the northwest flow weakens and high
pressure builds into the region.
We should see a fairly quick rebound Tuesday and Wednesday with
temperatures into the 50's as the high pressure system moves
offshore. Right now the forecast does hedge above the mean of|
the ensemble guidance on Tuesday but is closer to the ensemble
mean on Wednesday. Some uncertainty is present with the speed of
a cold frontal boundary moving toward the area sometime
Wednesday or Thursday of next week. For now, we went middle of
the road between the GFS and ECMWF with a shower chance for
next Wednesday night.

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.
