Discussion
Convection has come to an end this evening with a thin veil of
cirrus covering most of the area. Clouds should continue to
diminish overnight. Current fcst is in good shape with no update
needed.

For Monday, expect sctd CU developing during the morning as
heating commences, with some sctd showers tstms by early aftn.

While this might interfere with viewing the solar eclipse for
some, there should be an opportunity for most folks acrs the area
to witness some or even all of the it. Temperatures will again be
rather hot, climbing into the lower 90s by early aftn.

discussion...

short term... Tonight through Monday night
scattered showers and storms developed along the seabreeze this
afternoon mainly west of vermilion bay. Also weak energy rotating
over a broad anticyclone in east texas has aided in the development
of showers and storms over western and central louisiana. Coverage
of this activity should diminish late this afternoon. Dry weather is
forecasted for tonight. For Monday, subsidence ahead of upper tutt
low should keep lower than normal pops. Heat indices will again need
to be monitored but for now believe they will stay below criteria.

Long term... Monday night through Sunday
beginning Tuesday, appears that pops will be on the increase again
as upper low moves into the NW gulf. Models are quite diverse in the
handling of this feature, but overall it appears that this system
will meander and weaken over the NW gulf this week. Will keep
daytime pops mostly in the 40-50 percent range but could trend
higher in later forecasts if moisture profile becomes more
enhanced. For late next week and into the weekend... Will lower
pops slightly as broad upper anticyclone attempts to build over
the NW gulf. Temperatures should remain near normal and heat
indices should stay well below our advisory criteria of 108.

Marine...

surface ridge will remain near the northern gulf coast through much
of the week. An upper level low pressure system aloft will bring an
increasing chance for showers and storms on Tuesday. Light winds
and low seas are anticipated outside of any shower and thunderstorm
activity.

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.
