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.

Discussion Rather active day today with scattered to possibly
even numerous thunderstorms at times. Storm motion was very slow and
multiple boundary collisions led to a few areas seeing storms
persist for a little while leading to decent rainfall.
Ridge that was over the area and is breaking down will continue to
do so as a strong S W works southeast through the great lakes
region. This in combination with the mid level low overhead will
lead to even better rain chances tomorrow for much of the area.
Moisture will continue to be at a surplus with pws expected above 2
We will still have elevated rain chances to start the work week. The
combination of lowered hghts and a weak bndry trying to slide into
the area could provide a focus for at least mon. However by Tue the
deeper moisture could shift just to the north and east and while mid
lvl temps begin to rise. This will lead to slightly lower rain
chances on Tue but by mid week and through the remainder of the work
week the ridge should build back in enough overhead to provide near
normal to possibly even slightly below normal rain chances. With
that look for the heat to return Tue and through fri.
Aviation Biggest issue with respect to the tafs will be
convection. Convection will likely continue to impact much of the
terminals over sela along with mcb but looking at radar trends
coastal ms should be fine through at least the remainder of the
afternoon. However a few storms could still impact gpt this evening.|
Better chance for coastal ms could be during the early morning
hours. Outside of convection most terminals will deal withVFR
Marine Still looks like high pressure will build in from the east
across the northern gulf while a weak front tries to drop into the
area early in the work week. This should lead to a slightly tighter
gradient with winds out of the southwest. Winds may become more
westerly by mid late next week. Showers and thunderstorms will once
again be more prevalent during the early morning hours and of course
winds and seas will likely be higher near storms.

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.
