Discussion Localized low level convergence has kicked off
isolated shower and thunderstorm activity over vermilion parish
this morning. A weak seabreeze should expand east and west moving
through the remainder of the morning and into the afternoon
helping to trigger further development. Sufficient moisture
remaining over the entire area along with no capping will allow
for isolated development as convective temperatures are easily
met. Ongoing forecast looks good and no update needed.

some patchy fog has developed across the region this morning. With
the exception of ara, this fog has remained light with
visibilities ranging in the two to four mile range. Visibilities
will continue to vary for another hour or so before the fog
quickly dissipates. With upper level ridging aloft and weak high
pressure at the surface, the generally clear skies across the
region will continue through the morning along with light,
variable winds. Daytime heating will allow for isolated to
scattered showers and thunderstorms to develop this afternoon
beginning around 19z and dissipating around or shortly after 01z
thurs.

early morning sfc analysis shows weak high pressure situated over
the SRN appalachians ridging swwd over the WRN gulf region. Aloft,
water vapor imagery shows ridging in place to our north.

Satellite imagery sfc obs show generally clear skies over the
forecast area at this time... Although regional 88ds show a pretty
vigorous storm crossing coastal sern la and its adjacent waters.

Latest guidance indicates another day of widely scattered diurnal
convection, outside of the ongoing activity to our east which will
likely get into coastal acadiana adjacent coastal bays near
sunrise. Best pops are being carried across interior sern tx where
moisture is progged to be a little better. Main issue again today
looks to be the late summer heat as temps push well into the 90s.

Combined with dew points in the 70s, apparent temps are again
forecast to exceed triple digits across most of the forecast
area... Although values are currently not expected to meet exceed
heat advisory criteria. A few showers storms will likely linger
past sunset before dissipating... With overnight rain chances only
being carried near the coast where late night coastal activity is
again possible. Tomorrow looks like a general repeat of today with
small pops area-wide mainly due to daytime heating and maybe a
little better influence from an afternoon sea breeze boundary.

As we roll into Friday, rain chances begin to increase as the area
comes under the influence of a mid upper-level shortwave progged
to lift newd across tx, working in concert with increasing
moisture. These elevated pops continue on into the weekend as the
region remains under a lingering shear axis aloft. With the higher
rain chances cloud cover, high temps should drop back to more
seasonal values. Thereafter, long-range models hint at an erly
wave drifting wwd across the NRN gulf, helping maintain elevated
rain chances for late in the period. As has been the case for
several days now, a cool front is shown dropping swd toward the
forecast area late in the period, but as of now is not expected to
make it this far south.

Marine...

a mainly light onshore flow is forecast for the coastal waters
through the period with sfc high pressure anchored over the ern
gulf sern conus.

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.
