Marine Weather and Tides
Patterson, LA

Version 3.4
What's New / NOTES
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.

Scattered thunderstorms will continue across portions of the area
through 03z before beginning to dissipate with the loss of daytime
heating. Currently, the greatest potential for any
vcts operational impacts will be at kara over the next 1-2 hours.

Otherwise, only few sct cumulus from 3500-5000 feet will be
present through this evening. South southeast winds around 10
knots will decrease to 5 knots or less after sunset.

wx map shows the cold front moving across W tx, high pressure
ridging off the east coast through the western gulf, giving our
region a southeast flow. Scattered to numerous showers and
thunderstorms continue over central and southeast texas as far
east as hou to lfk. Current trends and short term guidance shows
this progression halting by the time it would make it to tyler hardin
counties this afternoon. Ongoing 30% chance there still looks
reasonable. Elsewhere, isolated showers and thunderstorms have
developed across the remainder of SE tx c and sc la this
afternoon, were the 20-30% looks sufficient for this.

Most short and long range models show high pressure aloft building
across the northwest gulf, with a low pressure trough continuing
over the eastern gulf and east coast. Increasing moisture from
the caribbean likely to spread slowly northwestward, gradually
increasing chances of afternoon showers and thunderstorms by
Thursday into next weekend. Confidence is fairly low on how much
rainfall we will get, with the gfs ECMWF canadian models all
having vastly different locations of the main trough axis and
associated moisture. Thus, continued blended guidance for the
extended with the best chances of showers and thunderstorms over
central and south central louisiana, lower chances further west
into southeast texas.

weak high pressure will continue to ridge over the coastal waters
through midweek. This should keep SE winds 5-10 kts and seas 1-2
feet. Daily shower and thunderstorm chances will begin to
increase by Tuesday and continue through the remainder of the week
as ridging aloft weakens.

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.
