Update
Water vapor and upper air analysis show an upper level weakness
and shear axis extending from mississippi through louisiana into
east texas. Very high moisture values are associated with the
shear axis with pwat values over 2 inches across the region.

According to 24 14z gps-met data, pwat values are from 2.2 to 2.4
inches across east central texas into central louisiana, where
convergence zone has kept nocturnal convection going, with some
locally heavy rainfall. ASOS at kpoe as of 24 15z has recorded
2.14 inches of rainfall, with radar estimates between 3 to 4
inches just west of there across western and southwest vernon
parish.

Hi-res models seem to have a decent handle on current convection,
with nocturnal activity beginning to decrease by noon time, then
isolated to scattered convection developing in the afternoon away
from areas where atmosphere has been worked over. Updated grids to
reflect this trend with high pops north of the highway 190
corridor through noon time, then tapering them off during the
afternoon, with isolated to scattered pops further south along the
i-10 corridor for the afternoon. Also, added some locally heavy
rainfall wording for the remainder of the morning for northern
zones.

for 12z TAF issuance.

Aviation...

regional 88ds show numerous showers storms associated with an old
outflow boundary and a weak shortwave aloft is continuing to fire
just to the N NW of the forecast area which is forecast to
continue slinking swd into the area... Most likely affecting kaex
in a few hours. Meanwhile additional convection is likely to break
out with heating a little later as the shortwave keeps pushing
sewd, with only kbpt not getting any precip mention with this
issuance. Otherwise expectingVFR conditions to prevail through
the period outside of any heavy precip.

prev discussion... Issued 327 am cdt Mon jul 24 2017
discussion... A short wave located to north of the area is
producing scattered showers and storms across much of louisiana
and east texas. The area also remains in a very soupy air mass
with pwats of around 2.25".

The short wave will keep a bit of divergence aloft in place today
and this combined with the very moist air mass will produce
scattered to numerous showers and storms, but mainly over interior
sections and closer to the disturbance.

A pattern change is expected through mid week as a mid to upper
level ridge will build in from the west. This will dry out the air
mass and suppress convection. On the flip side, this also means
high temperatures are expected to be a few degrees higher during
the middle of the week, but heat indexes are expected to remain
just below advisory criteria.

This weekend a back door front may move through the area. This
will increase rain chances as the front works through.

Marine... High pressure will remain over the northern gulf with
low seas and light onshore winds expected.

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.
