Marine Weather and Tides
Chalmette, 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.

Discussion
A more active weather pattern is expected this week and into the
weekend with daily chances for showers and thunderstorms. An
overall weakening of a ridge aloft and increasing and deepening
moisture across the region will result in more conducive
conditions for convective development... With perhaps the best
chances into mid week across the more eastern areas of the
forecast area closer to a mid upper low near the northeast gulf
coast that will slowly move northward and weaken. Toward the end
of the week and into the weekend there is still a considerable
amount of uncertainty with the eventual evolution of a disturbance
forecast to move into the gulf from the western caribbean and the
tropical moisture that will be associated with it. Forecast model
solutions still disagree on the development and movement of this
feature in the gulf and the development of a surface low. The gfs
solution remains east with a weak low moving toward florida while
the ECMWF is well to the west with a surface low tracking toward
the central gulf coast region... With the latest 00z run now even
farther west toward south central or southwest louisiana. If the
euro is correct, then it's quite possible that the memorial day
weekend period will be quite wet with the threat of heavy
rainfall. At this time, we will maintain high chance pops during
the holiday weekend period, but this may need to raised in later
forecasts. The increased shower and thunderstorm coverage and more
in the way of cloud cover will hold temperatures down a bit from
what have been recently observed. 11

Aviation
CurrentVFR conditions should remain through the rest of the
overnight period. As wave approaches from the east, moisture is
increasing with dew points near 70. This will bring early cumulus
development after sunrise, and could see MVFR ceilings by 14z or so
at most terminals. Convective chances are increased from the past
few days, especially at the eastern terminals such as kgpt, kasd and
the new orleans terminals. Will continue trends of previous package,
but may have to move up the timing an hour or two. Most convection
should die out near or shortly after sunset. Expect the stronger
storms to produce brief ifr conditions with potential gusts to 35-
45 knots. 35

Marine
Most of the workweek should see winds over the coastal waters remain
under 12 knots. This may change around Friday as low pressure tries
to form over or near the north central gulf of mexico. Could see
some exercise caution headlines necessary next weekend, but until
then, the main issue will be occasional convection with the usual
hazards possible. Could see some waterspouts in the morning hours
the next few days with the current weak wind fields. 35
