short term...

today through the weekend looks to be a dry forecast as surface high
pressure dominates and upper level troughing remains in place.

Continental air mass has brought the first light freeze of this fall
season with many locations again relatively close to freezing.

Strong cold air advection that was keeping the area cold will begin
to relax as the surface high centers directly overhead, breaking
down the wind field. Should sees temperatures bounce back quite a
bit today with highs in the lower 60s, which is still 10 degrees
below normal.

As the surface ridge building in shifts to just northeast of the
area on Saturday morning, will likely have cold air drainage setup
which will allow temps to fall back into the upper 30s to near 40.

The warming trend from airmass modification will continue Saturday
into Sunday with highs topping out in the mid to upper 60s. It will
be a pretty spectacular weekend with sunny skies each day.

Long term...

the GFS and ECMWF had been showing a weak upper level inflection
passing across the mid mississippi valley Sunday, bringing a weak
cold front through the CWA Sunday night. The ECMWF still shows that
but now the GFS holds off the boundary till Monday night. It really
shouldn't have any appreciable affect on the forecast either way as
it will be too dry to have precip and basically just provide a wind
shift.

The next possible forecast impact will be during the tues-thur time
frame. Models show another shortwave passing over the CWA in the
middle of next week. The GFS solution keeps the local area mostly
dry with stronger forcing to keep the upper trough, surface low, and
associated rain shield along the coast and into the gulf of mexico.

The ECMWF suggests rain making it as far north as the i-10 corridor
from baton rouge to new orleans and southward. Uncertainty remains
high with this feature and thus decided to us a blend of those
models in terms of pops.

generally clear skies (except for some high clouds) and good
visibility will meanVFR conditions will prevail through Saturday.

The only exception will be at khum where some patchy light fog may
occasionally restrict the visibility into the 3 to 5 mile range
mainly until 06-14z tonight. 22 TD bl
marine...

a dome of surface high pressure over the central gulf coast region
will remain over the region through the weekend into Monday. This
will result in winds around 10 knots or less and seas 2 feet or less
across all waters through Monday. Northeast to east winds are
expected to rise into the 10 to 15 knots range Tuesday and 15 to 20
knots over western waters on Wednesday as an inverted trough of low
pressure develops off the texas coast. 22 td

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.
