Marine Weather and Tides
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

815 pm cdt Tue jun 19 2018
This evening's sounding was routine with no problems encountered.
We continue to reside in a moist, southerly flow regime with the
vertical wind profile largely from the south from the surface to
300mb. This has kept pw values well above-normal with this
sounding at 2.01". The profile remains unstable with MLCAPE of
1074 j kg and LI of -2. However, with the lack of widespread
coverage of storms this evening, we were able to mix out slightly
in the lower boundary layer with only a few low-level cumulus and
mid-level altocumulus across the area. Klg

short term... Tonight and Wednesday...
this afternoon's surface analysis shows an area of low pressure
located across southern texas. Tropical moisture being advected on
shower by this area of low pressure has contributed to the
showers and thunderstorms ongoing across portions of southeast and
south- central louisiana this afternoon. The convection is
expected to continue through mid-evening before diminishing with
the loss of daytime heating.
Tomorrow, an upper level ridge and associated surface low pressure
will build westward over the northeast gulf of mexico. However,
enough deep layer moisture will remain in place to result in at
least 30%-40% pops during the afternoon.
Long term... Thursday through Monday...
an upper level trough is forecast to progress across the eastern
two-thirds of the CONUS during the long term period. The upper
level support for ascent associated with this system will result
in 30%-50% pops continuing on Thursday and Friday. The axis of the
through is forecast to move east of the region by Saturday and a
weak upper level ridge developing across the region through the
weekend. The associated upper level subsidence over the area will
result in decreased pops and increasing temperatures through the
a tight pressure gradient remains over the western gulf waters
will gradually decrease through this evening as low pressure
shifts westward and high pressure builds over the eastern gulf of
mexico. Onshore flow of 15 to 20 knots and seas of 3 to 5 feet|
will persist over the western waters through this evening before
beginning to decrease as the pressure gradient gradually eases
tonight and Wednesday. Winds and seas should drop to around 10
knots or less, and seas should fall to 3 feet or less for the
latter part of the week and the upcoming weekend.

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.
