Sounding discussion...

the sounding this morning still depicts the drier air in place at
low levels. Winds are light from the northeast at the surface
under a temperature inversion in the first 800 feet. Winds then
switch to westerly throughout the rest of the profile. Showers
and storms should again be confined to coastal areas and offshore
waters today. Low level moisture will begin to return further
inland later tonight.

short term...

no appreciable change in thinking from previous fcasts. Moisture
and higher dp temps will move back over the area starting tonight.

The pattern mostly looks to mirror a normal summer regime through
this week with basically hit and miss sh TS each day with a
diurnal fluctuation in development. The highest chances of sh ts
should be Wednesday and Thursday as a deep tropical moisture
surge moves in from the southwest late in the day Wednesday. This
occurs in response to the upper trough over the northeast
sharpening and gently digging to the southwest over east texas
forcing this deep moisture to the northeast ahead of the upper
synoptic trough, which is the reason this scenario is synoptically
viable.

Aviation...

most terminals should remainVFR with generally light and variable
winds and little in the way of cloud cover. The one holdout is khum,
where light rain has been falling. In addition, no observations have
been received for the last five or six hours. Therefore, amd not
sked has been sent with the 06z TAF issuance.

Marine...

front continues to be stalled just south of the louisiana coastline.

High pressure will continue to slowly build to the east-southeast
and the current offshore east-northeasterly winds will slowly begin
to veer around to easterly by tomorrow. Winds will continue to veer
around with onshore flow returning late Tuesday night and more so
Wednesday. Persistent southeast fetch across the gulf will dominate
throughout the rest of the week.

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.
