Discussion
A very progressive weather week is already underway this
afternoon as the tail end of a well defined shortwave swings
across the area sparking isolated showers and thunderstorms from
central louisiana northeastward. This activity will continue for a
few more hours and with decent instability values, its possible
that a few of these storms could be on the stronger side. Any
activity that does develop is expected to wane after sunset. The
trough slides quickly to the east this evening replaced briefly by
upper level ridging Tuesday.

By Wednesday a stronger upper level low and associated cold front
approaches the area. Conditions continue to appear favorable for
the development of severe thunderstorms Wednesday evening through
Thursday morning with forecast CAPE values in the 2k to 3k j/kg
range. Directional shear appears a bit limited ATTM but there will
be plenty of speed shear. Thus, I maintained the severe weather
wording in the forecast for Wednesday evening and expanded it to
Thursday morning. All modes of severe weather will be possible.

Once the front pushes through Thursday morning, we'll have another
brief respite from the precip before yet another system approaches
for the weekend. This system still has plenty of question marks. The
latest guidance now slows the system down with most of the
activity holding off until at least Sunday. The faster euro
pushes the precipitation clear of the area by early Monday with
the consistently slower and much wetter GFS keeping rain falling
across the area through Monday night. The GFS seems to be over
doing the QPF values (48 hour QPF totals over 10 inches compared
to the ecmwf's 1.5 - 2.5). I would almost blame this on some kind
of feedback issue, but the canadian falls between the euro and gfs
giving at least some credence to some higher rainfall values.

Will continue to monitor, but for now simply went with a blend of
the two.

Winds will relax tonight before increasing again on Tuesday in
advance of a cold front that will push through the area Wednesday
night into Thursday. The front will bring scattered showers and
thunderstorms some of which could be severe. Behind the front,
winds will turn offshore Thursday before veering back onshore
Friday in advance of another weather system expected to impact the
area late this weekend.

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.
