Synopsis for the middle texas coastal waters.. A moderate to strong southerly flow this morning will decrease through late morning ahead of a strong cold front. The cold front will move across the bays and coastal waters this evening, with strong offshore flow expected behind it. Small craft advisory conditions are expected this evening for the bays and coastal waters, then frequent gusts to gale force will develop by mid evening over the gulf waters where a gale warning is in effect for tonight. Offshore flow will begin to decrease on Sunday. Weak to moderate northeast flow Sunday night. Generally weak onshore flow anticipated Monday and Tuesday. Isolated showers anticipated Monday night in response to a weak coastal trough. Moderate northeast then north wind will develop Tuesday night and Wednesday as a surge of surface high pressure moves across the waters. Additional isolated showers Tuesday in response to the surge of surface high pressure and the associated upper level disturbance.

Discussion
See aviation discussion below for the 12z tafs.

Aviation
MVFR CIGS have developed across the eastern portions of S tx and
ifr lifr CIGS are across the brush country this morning.VFR
conditons are expected by mid morning. A low level jet around 30
knots has developed this morning, however sfc winds are sufficient
to preclude llws at this time. Sfc winds are expected to increase
through mid morning then shift around to the west ahead of a
strong cold front. Strong north winds are expected to develop
late this afternoon as the front moves to the south and southeast.

The strongest winds are expected to be this evening across the
coastal areas. Winds should diminish toward early Sunday morning
along with clear and dry conditions.

Previous discussion issued 420 am cst Sat nov 18 2017
short term (today through Sunday)...

a cold front currently moving across N and W tx this morning, is
expected to enter the N and W CWA between 11 am and 1 pm then reach
the coast between 3 pm and 6 pm and well south of the area by 9 pm
tonight. Strong north winds and cooler drier airmass will filter
into S tx behind the front late this afternoon and tonight. Advisory
conditions will develop across the bays and coastal waters beginning
around 6 pm this evening then continue to strengthen across the
coastal waters. Winds across the coastal waters are expected to
reach 25 to 30 knots sustained with frequent gusts to gale force
tonight. Therefore, a gale warning has been issued from 9 pm tonight
to 9 am Sunday. Winds are expected to decrease through Sunday
morning but will likely remain at advisory levels through Sunday
afternoon across the coastal waters. As for rain chances with the
cold front, moisture will be limited. Kept a mention of a slight
chance of -shra's along the coast and over the waters this afternoon
and evening. Much cooler and drier conditions expected tonight with
lows in the mid 40s across much of S tx to lower 50s along the coast.

Highs on Sunday will likely not reach 70 degrees despite abundany
sunshine.

Fire weather... Although strong northerly winds are expected to
develop this afternoon, humidity values will remain elevated. By the
time the humidity values drop to 20-30 percent on Sunday, the winds
will be much lower, therefore no fire weather concerns are expected
at this time.

Long term (Sunday night through Friday)...

cold temperatures expeced early Monday morning with readings in the
40s. The GFS and ECMWF deterministic output is generally consistent
in predicting an upper disturbance to move across the SRN plains tx
Sunday night Monday, followed by another distubance Tuesday along
with a transiton to a high amplitude upper pattern with a trough
over the ern CONUS ridge over the wrn CONUS and thus subsidence over
the CWA msa Tuesday night through the remainder of the period. Do
not expect significant precipitation associated with the Sunday
night Monday disturbance given dry atmospheric conditions (gfs
deterministic pwat values.) however, moisture convergence associated
with a weak surface coastal trough Monday night early Tuesday (gfs
ensemble mean) may generate isolated showers over the msa. The
Tuesday disturbance is expected to generate a surge of surface high
pressure across the CWA msa late Tuesday early Wednesday. Additional
isolated shower activity anticipated Tuesday afternoon night over
the msa owing to the combination of convergence associated with the
surge corresponding upper disturbance. Drier conditions expected
Thursday Friday owing to increasing subsidence.

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.
