short term...

beautiful conditions to last at least one more day. Warming will
begin before the muggies move back over the area. Friday will be
the transition day as temps will warm to around 90. But it will
remain rather dry through the day as dew pt temps will continue to
be in the low to mid 60s until Friday evening when southerly
winds will begin to bring the warm muggy conditions back. Everyone
will retire Friday evening with rather nice conditions and wake
up Saturday morning to dew pt temps back in the low to mid 70s
which will be noticeable. These conditions look to persist
through the majority of next week if not longer.

A cold front will move south and stall near the coast late Monday.

The northern portion of the area should see rain chances increase
Sunday ahead of the front. But Monday, the entire area should see
sh TS development with the exception of coastal sections from
terrebonne to stbernard parish. The battle ground of Monday's
activity will be where the frontal induced thunderstorm outflows
come in contact with the sea breeze which should be mainly over
the northshore areas and southern mississippi. The coastal areas
should observe subsident conditions behind the sea breeze that
moves well inland which would tend to suppress convective
initiation for those areas. Once the front stalls, some weak jet
support will keep sh TS in the fcast Monday night as well. The
trough that is left along the coast will remain a focus for sh ts
development helped along by the daily collision of a sea breeze.

This diurnally driven cycle should last through Friday.

As far as severity of weather is concerned, this may have to be
solved on a daily basis. Basically, it looks like a normal summer
pattern setting up with a better than normal scattering of sh ts
daily with one or two possibly breaking that severe barrier. But
the best chance of receiving a severe thunderstorm could be Sunday
and Monday.

Long term...

after Friday, the old trough boundary looks to possibly lift back
toward the northeast. If this occurs, it would take the sh ts
percentages down but cause the hot muggy conditions to be
maintained to a slightly higher degree by next weekend.

Aviation...

vfr conditions will prevail at all of the terminals through the
forecast period.

Marine...

high pressure will settle over the area today allowing the gradient
flow over the gulf waters to ease through the morning hours. Expect
to see winds shift from a westerly component at 10 to 15 knots to a
more southwest component at 5 knots or less by this afternoon as the
surface ridge moves directly over the coastal waters. As the high
shifts to the east tonight, winds will turn southerly and increase
to 10 to 15 knots. Seas will also decrease from 3 to 5 feet this
morning to 2 to 4 feet by the evening hours. High pressure will
remain parked over the eastern gulf through the weekend, and expect
to see the southerly flow to 10 to 15 knots persist. A weak frontal
boundary could slip into the area by next Monday. Winds could
decrease to 10 knots or less and turn more variable with the front
in the vicinity. 32

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.
