Discussion
Strong mid upper level ridging centered over texas and new mexico
will maintain its grip across the lower mississippi valley and the
central western gulf coast regions through Sunday before
beginning to retrograde toward the desert southwest for the
beginning of the work week. Meanwhile, the upper low trough over
the eastern CONUS will gradually weaken but leave behind a
weakness aloft over the southeast u.S. And the eastern gulf coast
region that will persist through at least the mid week period. All
of this means another scorcher will be on tap for Sunday with a
heat advisory remaining in effect for the entire forecast area...

with the exception of the the immediate southeast louisiana coast.

High temperatures in the mid 90s... And in a few places upper
90s... Again on Sunday will couple with high humidity levels to
produce widespread heat index values in the 108 to 113 degree
range. Rain chances on Sunday will remain minimal. It's possible
that a heat advisory will also be needed for parts of the forecast
area on Monday, but as the influence of the mid upper ridge
begins to wane across the area temperatures are likely to be a
couple of degrees cooler. In addition, there will be a slightly
better chance for convection on Monday as a weakness aloft shifts
south into the southeast states and toward the eastern gulf coast
region with an associated weak front or trough developing pushing
toward the central gulf coast. With lower heights over the region
next week, temperatures will moderate back toward normal levels
and convection chances will be on the increase. This somewhat
cooler and wetter trend looks to continue into next weekend as
another upper trough and associated cold front push into the
eastern conus. 11

Aviation
Vfr conditions to prevail at all terminals next 30 hours with
increased subsidence over the area. West winds to prevail and
increase to moderate levels throughout the day Sunday before relaxing
a bit Sunday night. 24 rr

Marine
Gradient compression takes place later tonight into Sunday morning
that brings westerly winds to moderate levels. Small craft exercise
caution criteria are met around midnight tonight in waters east of
the ms river and spread westward overnight. Winds then continue to
increase in the 20-25 kt range around daybreak Sunday and maintain
during the daylight hours before relaxing later in the evening. A
back door front of sorts generated from the east coast cyclone
moving into the DELMARVA region sends frontal forcing foci into the
forecast area for some convective potential in the coastal waters
Monday. Maritime convection may become a daily occurrence for much
of the week as upper low pressure dynamics settles into the central
gulf coast region. 24 rr

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.
