Short term
Surface high pressure is noted in the meso- and synoptic scale
analyses but the weather is being driven by some mid- to upper
level instability, that is convectively induced. A rather
prominent MCV has been detected off the southern end of the
chandeleur islands within the radar presentation that has
disrupted the typical land sea breeze circulation and focused
convection on outflow interactions in a very tropical air mass.

Precipitable water values of 2.34" this morning likely enriched to
over 2.50" prior to onset of rainfall. Rain rates at the office
(kasd) did attain 0.12" min rates (7.2" hr instantaneous) for at
least 15-20 minutes at peak intensity, with a measured
accumulation of 2.37" in about 70 minutes. 500 mb pattern shows a
general weakness between the continental ridge over texas and the
bermuda ridge. This is aiding in providing less subsidence and
somewhat enhanced omega to optimize the diurnal convective
pattern. Suffice to say, Tuesday may not look much different from
today with a repeat of storms initially on land breeze convergence
in the near shore waters that ultimately evolves into outflow
focused convection over land in the late morning and early
afternoon hours. Rain rates can once again be on the torrential
side. Near seasonable warmth with relief coming once rains begin
and spread in coverage.

Long term
Overall synoptic pattern does not really change much from day to
day though the rainfall coverage may flex around based on
wherever outflow convergences take place but it does appear a
more typical land-sea breeze circulation becomes better
established Wednesday onward. Temperatures to be influenced by
rain coverage but should reach near normal levels before becoming
rain cooled.

Aviation
Vfr conditions outside of convective influences, but lowering to
mfvr CIGS and ifr vsby in torrential rainfall at times mainly int
he daylight hours.

Marine
Bermuda ridge flow pattern to maintain light winds and low seas
that will become locally enhanced near thunderstorms complexes
that develop mainly in the overnight hours.

Decision support
Dss code: blue.

Deployed: none.

Activation: none.

Activities: marginal risk excessive rainfall.

Decision support services (dss) code legend
green = no weather impacts that require action.

Blue = long-fused watch, warning, or advisory in effect or high
visibility event; marginal risk severe or excessive rain.

Yellow = heightened impacts with short-fused watch, warning or
advisory issuances; radar support for slight risk severe
or excessive rain.

Orange = high impacts; enhanced risk severe; nearby tropical events;
hazmat or other large episodes.

Red = full engagement for moderate to high risk of severe and or
excessive rainfall, or direct tropical threats; events of
national significance.

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.
