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 over the northeast and mid atlantic states will
drift offshore today. A warm front will approach this evening
and move north late tonight into Friday morning. A cold front
approaches Friday, moving across the region late Friday night
into early Saturday. High pressure returns on Sunday into
Monday before a series of troughs and a cold front pass through
Tuesday into Wednesday.
Near term until 6 pm this evening
The forecast was updated mainly to account for mostly cloudy
conditions over some areas early this morning. The rest of the
forecast is still mainly on track.
An upper ridge axis will remain west of the region most of the
day, moving into the northeast around 00z Friday. Meanwhile
surface high pressure centered over upstate new york will drift
to off the northeast and mid atlantic coasts. The next shortwave
to affect he region will move into the great lakes region. The
upper flow will be somewhat blocky as the ridge builds and
moves slowly east. Will be dry with increasing clouds late in
the day as the ridge axis moves into the region.
There is a moderate risk for the development of rip currents at
the ocean beaches today.
Short term 6 pm this evening through Friday night
The upper ridge axis passes to the east and builds tonight into
Friday night as the upper pattern remains rather blocky as
heights rise as the ridge moves into the northern atlantic.
This will keep the shortwave from moving east and lifts into
southern canada and weakens as yet another moves into the upper
mid west and then into the great lakes region Friday night. At
the surface low pressure over the upper midwest will rotate
slowly into ontario and western quebec through Friday night.
A weak warm frontal boundary increases today and slow
approaches from the southwest this evening. Precipitation will
be delayed until late tonight as the warm front slowly pushes
into the region as the parent low remains well to the west. Best
chances or precipitation will be across northeastern new jersey
into the lower hudson valley. The region becomes warm sectored
Friday as the warm front lifts through. CAPE and surface based
instability increase during the day as the cold front slowly|
approaches. There may be a break in the precipitation of a brief
time once the warm front lifts north, and until the cold front
nears later in the day. Best instability will be inland as a
deep southerly flow keeps a marine layer across long island and
into southern connecticut. Best chances of thunderstorms,
possible strong, will be inland Friday afternoon into the
evening. Then the storms will weaken and move into long island
and southern connecticut Friday night.
Long term Saturday through Wednesday
Cold front moves through the area during Saturday with a chance
of lingering showers and thunderstorms in the morning. Models
then agree that the available moisture is probably too low for
consideration of afternoon showers and storms, especially since
a lagging upper trough and shortwave appear to be too late to
arrive for necessary lift and mid level instability. Will
therefore go with a dry forecast for the afternoon. Then with
stabilizing lower levels, the upper trough should pass through
dry during Saturday night. An even blend of mav nam MOS looked
good for temperatures.
High pressure builds in on Sunday and lasts into Monday as the
upper flow becomes zonal to anticyclonic. Dry weather for both
days with highs mostly in the mid 80s.
For Tuesday into Wednesday, low pressure tracks across
southeastern canada. This will bring a couple of pre-frontal
troughs here before a cold front eventually passes through
sometime most likely on Wednesday. Looks like the best
combination of moisture, lift and shear could be late day
Tuesday into Tuesday night. Will cap pops at chance Tuesday
through Wednesday for now given the timing uncertainty of the
surface features and sources of lift aloft. Highs generally in
the 80s both days.
Aviation 11z Thursday through Monday
High pressure will slide offshore today before a warm front
approaches from the southwest tonight.
Vfr through the TAF period.
Light northeasterly winds will veer to the southeast between
17-18z as the high shifts offshore. Klga may remain NE for a
bit longer before turning se.

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.
