For the 24 12z TAF issuance.

Aviation
A mid level disturbance and a surge of tropical moisture will
bring numerous showers and a few thunderstorms throughout the
morning into the afternoon hours at the terminals. MVFR ifr
ceilings and or visibilities can be expected when the stronger
rain showers or storms move over the terminals. A brief break in
the shower activity is expected after 25 02z.

short term [today through Monday]
a surface trough extending across the western gulf of mexico
beneath a weakness of the upper level height fields is expected to
support numerous showers and thunderstorms along the northwestern
gulf coast through the weekend. This morning's regional radar
mosaic already shows convection developing and moving inland along
coastal southeast texas and southwest louisiana.

Abundant deep layer moisture is already in place across the region
with a pwat of 2.23" sampled in the 00z klch sounding. The
majority of model guidance indicates that pwats are expected to
increase through the day with values around 2.5" in place across
the region this afternoon. In addition to the above normal pwats,
the 00z klch sounding indicated a deep warm cloud layer in excess
of 10 kft and relatively light winds through much of the lower
troposphere. All these factors will support efficient
precipitation production and the potential for heavy rainfall
with convection today. Total rainfall amounts of 1 to 3 inches are
expected with the heaviest totals confined to the i-10 corridor
south. However, should a weak surface circulation be induced by
the convection as is being depicted by some of the cams (in
particular the arw) there will be the potential for more organized
bands of storms and even heavier rainfall totals of 5+ inches in
localized spots. Therefore, a threat for flash flooding continues
and the flash flood watch was left unchanged.

Similar conditions will persist through the day on Sunday before
the shortwave trough axis shifts east of the area and results in
less favorable upper level support for ascent. The shortwave
trough will also contribute to the surface trough lifting
northeastward on Sunday and into Monday. Widespread showers and
thunderstorms with the potential for heavy rainfall will continue
on Sunday before beginning to decrease from west to east on
Monday.

Long term [Tuesday through Friday]
another shortwave is forecast to dig into the central plains
during the Tuesday to Wednesday timeframe. This should provide
enough support for a surface boundary to push southward to the
gulf coast along with some slightly drier air. As a result, a more
typical late august weather pattern is expected with chances for
isolated to scattered showers and thunderstorms each day, mainly
from mid-morning through the late afternoon hours. Temperatures
will also return to normal values with highs in the low to mid 90s
and lows in the low to mid 70s.

Marine...

a weak surface trough over the western gulf of mexico will result
in light to occasionally moderate onshore flow will continue
through the weekend. Additionally, numerous showers and
thunderstorms will continue across the coastal waters today and
Sunday as tropical moisture associated with this trough moves
across the region. Daily precipitation chances will trend closer
to normal by early next week.

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.
