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.

Short term (today and tonight)...
clouds will be increasing through the day as isentropic lift
strengthens ahead of the approaching low pressure system, which is
now near the ks mo border. As it tracks into the ohio valley
region this afternoon, s-sw winds at 850 mb will increase to
around 50 kts, creating gusty conditions area-wide. Moisture
remains confined below an inversion around 750 mb today, and only
increases in depth after 00z in forecast soundings. Once the
inversion erodes, we develop some weak instability that should
allow for some isolated thunderstorms in the evening.
Frontogenetic forcing moves through in the 02-07z time frame, with
strong advection of colder drier air occurring through the rest
of the night. A change of precip to snow in higher elevations may
also occur, enhanced slightly by a 30-35 kt NW flow, but any
accumulations will be less than one inch through 12z.
Long term (Saturday through Thursday)...
upper trough will move quickly east of the area Saturday
night Sunday morning with northwest flow aloft. Boundary layer
moist and cold enough in the morning Sunday to produce a chance of
snow showers flurries across the west northwest facing slopes.
Drier air will advect into the region with snow showers ending and
clouds dissipating in the afternoon Sunday. A much cooler day is in
tap for Sunday.
Upper flow pattern quickly de-amplifies flattens for Sunday night
and Monday with strong surface riding producing mosty sunny
For Tuesday and Wednesday, another strong upper trough moves across
the great lakes with trailing front moving across the tennessee
valley. This frontal boundary will be moisture starved given the|
gulf moisture will remain south and east due to continued surface
ridging over the gulf coast states.
There is a potential of seeing some orographic showers snow showers
over southwest virginia northwest tennessee early Wednesday, but
confidence too low to mention. Will keep frontal passage mainly dry
For the latter half of the week, models differ in the evolution of a
gulf coast system that moves into the southeast united states. At
this time, plan on following the dry northwest flow aloft ecmwf
pattern along with surface ridging. Will keep thanksgiving
day and Friday dry.

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.
