Update
Moderate onshore flow continues across SE tx tonight, centered
between an area of low pressure situated over N tx, and a ridge of
high pressure building in from the east. A combination of both the
wind, and mid level clouds, which should fill in by the morning
hours will keep temperatures warm in the mid 70s. Went ahead and
raised hourly and low temperatures for tonight by a degree or two
area wide to account for our latest trends in observations.

Otherwise the forecast appears to be in good shape.

aviation [00z TAF issuance]...

vfr conditions should continue for most of the area for the next
6 to 9 hours. After 09z MVFR ceilings look more likely for
kcll kuts kcxo with kiah on the edge of lower ceilings. Tafs will
keep MVFR ceilings for these areas but could change kiah to
having a temporary MVFR condition.VFR will continue through the
morning for ksgr khou southward. Winds should pick up again after
14-15z tomorrow which will allow ceilings to come back up and
scatter for much of the day. Tomorrow looks to be a bit of a
repeat of today.

discussion...

less convective activity today than yesterday across the area -
virtually none, really - and that will be the case for most of the
holiday weekend. Rain potential will slowly increase through the
week. If you're going to see rain this week, it will most likely
be Wednesday or Thursday.

Near term [through tonight]...

outside of a couple showers that developed over the gulf and were
able to briefly push onshore before dissipating, it's been dry
across the area today; well, from a rain standpoint, anyway. It's
also been fairly humid, though locations away from the coast have
been able to see dewpoints mix into the upper 60s. We finally
succeeded in falling into the lower 70s up north last night, and
we should see lower to middle 70s again away from the coast. At
the coast, however, those continued onshore winds will keep
temperatures from falling out of the upper 70s yet again.

Short term [Saturday through Sunday night]...

this weekend can basically be summed up in a single word: ridge. A
594ish midlevel ridge will be centered over the southeastern
states, and we'll be firmly underneath the control of stacked high
pressure through the column. As we've seen recently, this is going
to mean high temperatures near or above 90 degrees, and virtually
nil rain chances. By late Sunday the ridge will retrograde back
towards us some, probably aided by rising heights in response to
an upper trough over the western us. But, the ridge as a whole
will be weakening, so the ultimate impact on our weather probably
will not be all that significant... Or even noticeable for that
matter.

Long term [Monday through Friday]...

change finally starts to show on Monday as the upper trough inches
closer and we begin to see weakness in the ridging over us.

Temperatures may be a bit (no more than a few degrees) cooler. The
question will be if that weakness is enough to see any
shower storm development on Monday. Onshore flow should help with
lift. Both the GFS and euro show very subtle vort maxes moving
through Saturday, which could also help support lift. Not going to
get gung ho with the pops here - but i'm pretty comfortable with
the small area of slight chance pops i've inherited here.

The big question really comes later in the week as the upper
trough ejects across the central plains towards the great lakes,
and low pressure spins up in the lee of the rockies. Will it be
enough to drive the tail end of the cold front down into southeast
texas... Or at least close enough for us to see enhanced convection
in our area? The GFS and euro continue to narrow their
range... Indeed, the euro has now become the one most aggressive
with the southward extent of the front, bringing it right to the
edge of our area before killing it off. For what its worth, the
cips extended analogs also seem to show a divergent signal - one
cluster in which the front hangs up in north texas, and another in
which it is able to penetrate into the area. I've been capping
pops in the slight chance range for the past couple days, but will
let them begin to drift up into chance today. I still suspect this
is more of a middle road that will then be either ramped up or
down to the scenario that ends up emerging as more likely, but i
think there's enough evidence now to stop arbitrarily capping the
rain chances.

Marine...

mainly moderate onshore winds and elevated seas will persist
through the weekend, and small craft exercise caution flags
will occasionally be needed. The winds have come down a little
this afternoon but are expected to come back up again overnight,
so will maintain the caution flags through the nighttime hours.

South to southeast winds generally in a 10 to 20 knot range and
seas generally in a 3 to 6 foot range can be expected for the
first half of next week.

Despite the slightly lower southeast winds, the coastal flood
advisory will continue for now as the onshore fetch persists.

Minor coastal flooding with wave run-up remain a possibility
(especially during high tides) for gulf facing locations.

Additionally, the surf will remain elevated to rough at times...

with strong rip currents a concern given the increase in beach
goers for this holiday weekend. 42

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.
