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 strong cold front will cross tonight bringing strong winds
and a changeover to snow showers by early Sunday morning.
Near term until 6 am Sunday morning
Rain with the front will continua tonight. Current timing of
precip with the boundary looks good, so minimal change was
needed. There may still be a rumble of thunder but overall,
coverage has diminished. Will maintain the flood watch as is for
now, until precip with the front crosses. Boundary is rather
progressive but some isolated issues may still arise as upwards
of 2 inches of rain was reported along the watch area.
Still expecting a period of strong winds with the front as it
crosses and behind with as lapse rates steepen. While pressure
rises are rather impressive, many of the obs upstream have not
reported gusts to advisory levels. This and some of the newest
hi res guidance keep gusts below thresholds outside the terrain.
Thus, will hold off on any wind advisory, but it will still be
Changeover to snow is expected overnight as cold air returns to
the region. Warm and saturated ground will limit accumulation
at first, with rather low snow ratios but this should improve as
the core of the coldest air approaches later Sunday.
Short term 6 am Sunday morning through Tuesday
Northwesterly flow will continue scattered snow showers and
keep temperatures in the 30s through the day. Highest pops
remain the snow belt north of i-80 and in the mountains of
pa WV md where lake enhancement upslope is anticipated. Still
thinking 2-4 is reasonable, though some higher amounts may be
possible. Best window for accumulating snow in the terrain looks
to be as the second shortwave dives through the trough tomorrow
afternoon, deepening the saturation layer through the snow
growth zone, but this only lasts for a short period of time.
With this in mind, have opted not to issue a winter weather
advisory at this time though consideration will be given on
Building ridge of high pressure and backing flow should end|
chances for showers by Monday morning, with dry conditions
expected through Tuesday. Some warming is expected under an
upper ridge, which should get us closer to seasonal values by
Long term Tuesday night through Saturday
Minimal change was needed in the extended. The majority of the
week will be dry with seasonal temperatures outside of a weak
wave progged to pass to the north midweek. Have kept slight
chances in for locations north of i80 on Wednesday. Next system
is progged for late in the period, with broad troughing in
place. Model guidance differs, so opted to stay near a blend of
Aviation 23z Saturday through Thursday
Any improvement above MVFR will be brief this evening as the
warm sector of low pressure digging toward the southern great
lakes traverses the area. Expect redeterioration to ifr with
rain and then snow as the systems cold front crosses in the
predawn of Sunday.
The strong pressure gradient of this system will continue to
support llvl wind shear and gusts of 30 to 40 kts with the
frontal passage tonight.
MVFR stratocu will linger in the cold flow behind the front on
Sunday, in addition to local ifr in snow showers, especially at
fkl and duj.
The next chance for restrictions is expected with a late Tuesday

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
