MVFR CIGS should lift throughout the morning. An isolated shower
or storm may be possible this afternoon, but chances are far too
low to include in the taf. MVFR CIGS may return overnight tonight.

Otherwise, light to moderate southerly wind is expected through
the TAF period. 11

discussion...

warming 850 700mb temps will likely inhibit much in the way of
precip today - especially for portions of the region west of
i-45. Continued southerly flow will persist and am not expecting
the current 75-79f dewpoints to mix out all that much. Warm temps
and high humidity will combine to produce some 107-109 degree
heat indices today... Generally along and west of a college
station-edna line. Went ahead and issued a heat advsy for that
area this afternoon. Expect 103-107 indices further east.

A weak cool front is forecast to sag into SE tx on Saturday. Pw's
pool to 2-2.3" ahead of the front and 850 700mb temps diminish
whereas capping shouldn't be much of a concern. Expect
showers thunderstorms to increase in areal coverage with daytime
heating. With a general weakness situated aloft and light
steering flow, storm motions appear to be less than 7kt so
locally heavy rain appears to be possible. A second concern is
a possible collision of the seabreeze with precip along the front
during the afternoon - which would enhance rain rates & storm
strength where it occurs. Unfortunately this many times is close
to the metro area. Just something we'll be watching...

elevated moisture levels, a diffuse front, and a mid upper level
weakness will linger into at least the early part of next week.

This should provide fairly good chances of shra tstms each day,
most likely diurnal in nature W precip offshore at night
transitioning inland during the day. Same general setup, minus the
surface boundary and maybe not as much resident moisture, will
probably persist for the remainder of the workweek. 47
marine...

moderate southerly winds should slacken some later this morning, but
6-7 foot seas will likely stick around for most if not all of the
day today and into tonight. For this reason, the small craft
advisory was extended for the offshore waters through 3 pm this
afternoon with a scec in place after that lasting into tonight.

Winds and seas will continue to slowly diminish into the weekend,
with periods of moderate onshore flow and elevated seas returning
around midweek.

Tides are still elevated tonight with some possible coastal flooding
in the usual areas like surfside, blue water highway, and highway 87
at 124 on bolivar. A coastal flood advisory has been issued for
these areas as high tide is approaching. Tide levels should come
fall below critical levels by mid morning. Astronomical high tides
will be above 2 feet the next few days. The good news is wind seas
should gradually diminish, but we'll continue to monitor conditions
for the usual spots prone to elevated water levels. 11

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
