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.

A cold front approaches Tuesday night and passes through the region on Wednesday. At the same time, low pressure over the southeast approaches the mid- atlantic and moves out to sea. High pressure builds through the region to close out the week. A cold front passes through the region Saturday, then low pressure will be over eastern canada over next weekend.

Low pressure over southeast canada will continue to lift to the
north and east tonight. Meanwhile, high pressure over texas
builds east through the gulf coast states and will move off the
mid-atlantic coast Monday night. A cold front approaches
Tuesday night and passes through the region on Wednesday. At the
same time, low pressure over the southeast approaches the mid-
atlantic and moves out to sea. High pressure builds through the
region to close out the week. A cold front passes through the
region Saturday, then low pressure will be over eastern canada
over next weekend.
Near term until 6 am Monday morning
Strong northwest flow continues across the area between an area
of low pressure to our northeast across southeastern canada,
and high pressure to our southwest across the lower mississippi
valley. This tight pressure gradient will continue through
tonight and will keep winds elevated overnight. However, wind
gusts will continue to diminish this evening, and may drop off
for many locations overnight.
With the northwest flow, clouds will continue to to be trapped
under inversion around 4,000-6,000 feet and remain across most
of the area. The thickest clouds cover will be from the i-95
A short wave vorticity impulse and an area of enhanced low
level lift and moisture will move across the northern half of
the area later this evening and overnight. The combination of
the lift and moisture associated with the short wave vorticity
impulse may be enough that may help any lake effect streamers
within the northwest flow may make their way into portions of
our area overnight. There will be a slight chance of isolated
snow showers flurries later tonight for areas along and north of
the i-78 corridor. The poconos may have the better shot of
seeing any accumulation if any showers do occur.
Short term 6 am Monday morning through 6 pm Monday
Monday is expected to be a fairly nice day. The pressure
gradient relaxes some during the day as high pressure builds to
our south, but there will remain a steady breeze through the
day. Also, winds will be gusty around 20-25 mph through much of
the day as well, but much less windy than Sunday.
There will remain some scattered cloud cover across the area,
especially in the morning hours and areas along and north of the
i-95 corridor. Skies are expected to begin to clear out by he
afternoon. No precipitation is expected through the day on
Monday as any lake effect streamers will get cut off or push
north of our area as the flow turns more west to southwesterly
through the day and moisture lift becomes limited as well.
Long term Monday night through Sunday
High pressure over the mid-atlantic moves out to sea Monday
night and will be off the mid-atlantic coast on Tuesday. Return
flow sets up, and highs on Tuesday will be about 3-5 degrees
above normal, topping off in the 40s in the poconos, otherwise
in the low to mid 50s north and west of i-95, and near 60s in
the DELMARVA and southern nj. S to SW winds increase Tuesday
afternoon to 15-20 mph with gusts up to 30 mph.
High pressure moves out to sea late Tuesday as a cold front
moves through the great lakes and ohio valley. Meanwhile, low
pressure develops over the gulf coast on Tuesday, and that low
moves off the southeast u.S. Coast Tuesday night. Tuesday night
through Wednesday morning, that low approaches the mid-atlantic
coast and drifts out to sea. That cold front will pass through
the region Wednesday afternoon. Based on latest model guidance,
will carry a swath of likely pops across southern de and
southeast nj, and chance pops for most areas south and east of
the fall line. Cooler temps will move into the poconos Wednesday
afternoon, but stronger CAA will not be underway until
Chilly high pressure builds through the region thanksgiving day
with temperatures 6-8 degrees below normal. Highs top off in
the mid and upper 30s in the poconos, otherwise in the low to
High pressure reestablishes itself over the area Friday with
highs a few degrees warmer than Thursday.
Low pressure passing well north of the region will drag a cold|
front through the region on Saturday, and then low pressure
remains over eastern canada through next weekend. Unsettled
Aviation 20z Sunday through Friday
The following discussion is for kphl, kpne, kttn, kabe, krdg,

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. 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.
