Short term
Should see a good bit of activity start up relatively early today
as a cold front moves at a strong pace for this time of year. The
trough axis is actually just north of the area from alexandria to
just south of jackson at 330am. The air mass change(cold front)
is over northern louisiana and northern mississippi. The trough
axis is what will help get things started this morning as it will
provide an extra focus for sh TS to develop. The front should be
over the northern gulf by mid to late afternoon taking only 8
hours to traverse the cwa. But upper level support and other
baroclinic dynamics will begin to ease up causing the front to
stall over the northern gulf. This has been discussed at length
for several days along with the possibility of a sfc low forming
along the boundary once it stalls. This low would be just like any
frontal low basically starting off as a kink in the front due to
strong thermal differences between the water sfc and the air along
and behind the front. It would take time, but this feature could
evolve more subtropical or even tropical characteristics. Negative
local impacts over land are not expected to be an issue at the
moment as the low should move along the frontal interface to the
east or northeast. Although, marine impacts may be different with
respect to winds, seas and thunderstorm activity.

The tropical prediction center has put a 0% chance of formation
over the next 48 hours which makes sense. Any possibility of a
tropical or subtropical sfc low would only be able to form once
the major baroclinic support moves away. This is what causes the
boundary to stall tonight and wed. But over time within the next
five days, they give it a 20% chance of formation. This takes into
account that the environment is able to modify over time into a
more tropical one possibly alowing the sfc low to deepen somewhat.

Once the front moves through, winds will change to northerly and
eventually easterly by Thursday. If the low is capable of forming,
then these easterly winds would rise a bit which could bring some
rise in tides. The synoptic fcast is much stronger than the
mesoscale fcast in that we fully expect a surge of moisture back
into the area by Friday or Friday night. If a surface low forms
along the front over the northern gulf, what would not be a good
idea is that the low sits on the front without moving much, then
as the front or what is left of it surges northward, it would be
this deep moisture associated with a sfc low coming back with it.

The current fcast brings the low east or northeast which is a
much better scenario for the land portions of the area with some
minor tide rises for coastal sections and some moderate impacts to
marine areas. How this scenario plays out will be the basis of
the entire fcast over the next few days.

Conditions are currentlyVFR right now but will tend to degrade at
times as a cold front currently located near northern la sags
southward into our area brings widespread convection. There are not
a lot of showers thunderstorms right now but an increase of coverage
is expected as it moves through the area later today. Showers are
likely ahead of the front then will be mostly thunderstorms through
the day that pop up which could bring conditions down to MVFR ifr
for both ceilings and visibility. Storms could produce frequent
lightning or gusty winds. Winds will also be shifting from
southwesterly to north northwesterly as the front passes. Will
attempt to time any specifics for convection where clear trends show
up but otherwise will be going with vcsh and vcts. Once the cold
front pushes past the area conditions should improve toVFR again. Bl

A cold front is currently expected to reach the gulf later tonight
into tomorrow. This will bring showers thunderstorms and a wind
shift from onshore to offshore flow. Winds speeds will be
increasing behind the front and a small craft exercise caution may
be needed for the nearshore waters tonight into tomorrow. After
that, winds will lighten up again and then slowly swap back to
onshore flow around Thursday Friday. -bl

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.
