See aviation discussion below for the 06z tafs.

Aviation
Brief MVFR conditions due to light patchy fog and occasional CIGS can
be expected early Wed morning, mainly from ali to vct and cot.

Otherwise,VFR conditions are expected a majority of the taf
period. Brief isolated showers or thunderstorms will be possible
wed, mainly east of the brush country. Due to the low probability,
will not mention in the tafs at this time. A weak to moderate s
to SE flow will persist through wed.

Aviation...

winds will decouple through 08z wed. A period of MVFR CIGS will be
possible, mainly inland from ali-vct with brief mention toward cot
shortly after daybreak. Maintained mention of br between ali-vct
as well, with possible ifr at ali. Improvements are expected
through the morning with s-se-ly winds gradually increasing. Gusts
of 15-20 kts possible. Isolated shras will be possible from crp-
vct tue, but due to isolated coverage, will not mention in tafs
at this time.

short term (tonight through Wednesday night)...

the mid to upper level ridge will remain situated over north
central texas tonight through Wednesday night. Drier air in the
low levels will continue over the region tonight with the higher
moisture axis staying over the gulf waters. Isolated showers
are expected to form offshore late tonight and move toward the
coastal regions after daybreak Wednesday. Precipitable water
values will go up to around 1.8 inches over the coastal plains
Wednesday afternoon, so could see some isolated convection along
the sea breeze boundary. The moisture is expected to increase
slightly over the coastal waters with pwat values up to 2 inches
late Wednesday night. Coverage of convection expected to become
scattered overnight offshore and possibly approach the coastal
counties before daybreak. High temperatures will be just slightly
below reading for today. Afternoon heat index values will again
range from 105 to 109 degrees Wednesday.

Long term (Thursday through Monday)...

overall synoptic pattern remains consistent through the weekend,
with our persistent summer ridge drifting northward just enough to
allow a weak trough to drift westward underneath the ridge across
the northern gulf. Rain chances focus on where support from the
trough will be able to work on significant moisture inflow. Model
projections continue to indicate showers and thunderstorms out over
the gulf, with more limited ingress onto the coastal plain.

Moisture totals appear healthy, with pwats around two inches on
Thursday, increasing to 2.2 to 2.3 on Friday before backing off
somewhat over the weekend. Later in the weekend moisture pooling
further west may allow for seabreeze convection over inland areas as
well, with isolated activity continuing into the first part of next
week.

Temperatures will remain warm through the extended period as
expected for mid-august, but perhaps a notch below previous days due
to increased cloud cover. A well-timed isolated shower could also
affect afternoon high temperatures. Humidities will remain high,
with heat indices at least in the 105 to 109 range across much of
the coastal bend.

Marine...

weak to moderate onshore flow is expected through the weekend.

Increasing moisture will contribute to scattered showers and
thunderstorms Wednesday night through Saturday, with continuing,
although lower, chances into early next week.

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.
