increase in MVFR CIGS later tonight with a relaxing in the winds
some which will hold through most of the day tomorrow.

discussion...

eastern texas weather under the continued suppressive control of
southeastern u.S.- centered upper ridging. One recent (minor) caveat
has been that of a slightly drier air mass recently advected in from
the gulf upon southerly steering flow. Resultant lower 70 f dew
points will be best felt during the overnight hours as minimum
temperatures fall closer to their near 70 f late may standards.

Daily conditions remain carbon copy from the day before... Upper 80s
to lower 90s by the early afternoon with mid afternoon %rhs
bottoming out in the bearable lower to middle 50 percentile. Another
caveat of note may be a slightly hazy appearance to the sky from
smoke emanating from fires burning in mexico... From the east coast
around to campeche and the yucatan peninsula. Expect the occasional
sprinkle or very brief early day shower across the southern third of
the CWA through memorial day.

Energy diving into the great basin from california will carve out
a large trough through tomorrow. Heading into Tuesday shortwave
disturbances will eject from this broad open wave trough and into
the north central plains. This will aid in pulling the main
trough axis east and this will work on our currently anchored
southern u.S. Ridging. At the same time another lobe of southern
energy will swing around from the west coast and into the desert
southwest... Entering the big bend region early Wednesday. This
vort MAX will be entering a less stable, heated and more humid
central and eastern texas environment. This energy will take a
northeastern ride up and over the east gulf upper ridge. This
will be the impetus to a possible qlcs riding across oklahoma and
northern texas during the day Wednesday. As of now, this mesoscale
feature is anticipated to spit out cool pool-induced outflow
boundaries into our forecast area... Increasing convective chances
into the moderate (40%) category on Thursday. Our downstream
Thursday environment will lack bulk shear but this will be made
up in the thermodynamics. Greater than 2k CAPE -5 l.I. 25-35 k
indices indicate widespread northern into central county daytime
thunderstorms. All of the above has to unfold through late may to
give the area the best chances for showers and storms on Thursday.

High pressure builds in from late Thursday on into the first
weekend of june. Models are all over the place concerning next
weekend's rain chances. All paint in light QPF both days as texas
falls under a more zonal flow pattern. Overcast with periods of
light precip are plausible. Southern-based upper ridging expands
north into the state early next week and eventually centers over
the gulf. This will set off another period of early june dry
weather. 31
marine...

southeasterly to south winds should continue through Thursday
morning at 10-17kt increasing slightly Sunday night and again Monday
night. The scec up for the gulf waters early this morning will be
ending at 12z. With that increase in winds will probably see the
scec return for Sunday night. Slight lessening in the gulf waves
tonight Sunday with some improvement in beach runup and slight
improvement in rip currents. Currently will maintain the beach
hazards statement through Monday afternoon for these gulf facing
beaches. Tide levels should continue at 0.6 to 1.4 ft above normal.

Cold front or cold pool storms should drift down into setx Thursday
and may even drift into the bays late Thursday night Friday morning
before the boundary lifts back north. This would likely become a
focus for greater coverage with showers and thunderstorms. 45

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.
