Synopsis for the middle texas coastal waters.. A weak to moderate northeast flow is expected today over the coastal waters as a warm front approaches the region. Northeast flow will become weak tonight and will shift to onshore as the warm front moves inland Friday. Isolated to scattered showers will be possible today through Friday. Patchy sea fog is expected to develop over the bays and near shore waters by Friday morning as the warm front moves to the coast. Rain chances will continue across area waters Friday night and into Saturday until a cold front moves across the area. Areas of fog may result in reduced visibilities through Saturday morning until the frontal passage. Moderate southerly winds are expected Saturday morning before the front, with weak to moderate offshore winds behind the front. Wind speeds should diminish slightly during the afternoon. Drier conditions are expected for Sunday, but more rain chances are expected on Monday as a weak to moderate onshore flow returns to the area.

Discussion
Updated for the 18z aviation discussion.

Aviation
Low-level moisture streaming over a stalled frontal boundary
just offshore continues to result in a broad expanse of MVFR
ceilings along the coast. However, the clouds have lifted farther
west at klrd whereVFR flight conditions prevail. Ceilings will
gradually lower at all TAF sites overnight into the ifr range.

Patchy fog drizzle along the coast may lead to intermittent
instances of lifr flight conditions, especially 22 06z. Ceilings
and visibilities will likely improve very little after daybreak
Friday.

Prev discussion issued 547 am cst Thu feb 21 2019
discussion... Added a mention of patchy fog after midnight over
the coastal plains that should linger into early Friday morning.

See aviation section for 12z tafs.

Prev discussion... Issued 411 am cst Thu feb 21 2019
short term (today through Friday)...

the frontal boundary remains over the northwest gulf of mexico
east of the offshore waters early this morning. Moisture continues
to override the shallow cool air mass in place over the region.

Southerly low level flow of 25-30 knots around 85h will continue
over the coastal plains this morning and provide a chance of
light showers. Low level warm air advection will shift to the east
with the low level jet with rain chances diminishing to slight
chance over the victoria crossroads.

A strong upper low will slow move through the great basin today
through tonight and then lift out towards the four corners region
late Friday afternoon. A short wave trough over northwest mexico
this afternoon will move northeast across coahuila into the
edwards plateau late tonight. Low level flow will increase again
over the coastal plains with the warm front moving into the
offshore waters during the night. Isolated to scattered showers
are expected to form over the coastal waters and move inland
during the night.

The short wave trough will move into south-central texas on
Friday. The warm front is expected to move inland during the
day. Moisture will increase over the coastal plains, especially
towards the victoria crossroads, where precipitable water values
will increase to around 1.5 inches. Scattered convection is
expected for the coastal plains. Instability will increase by
the afternoon to warrant a mention of thunderstorms, mainly for
the victoria crossroads.

Long term (Friday night through Wednesday)...

an upper level low is progged to lift northeast from the SW conus
toward the plains Friday night Saturday, which will bring a cold
front across S tx on sat. Models are in pretty good agreement with
the front reaching the coast some time Saturday morning before
18z. Ahead of the boundary, southerly winds will usher moisture
into S tx that will combine with an embedded short wave rounding
the base of the low to produce isolated scattered convection
across S tx. The better chance will be across the vct area where
better instability and the deepest moisture will be located.

Moderate CAPE warrants mentioning iso tsras Fri night into sat
morning. Rain chances are expected to end from west to east as
drier air filters into the area behind the exiting upper
disturbance and associated cold front on Saturday. Saturday will
be rather warm before the colder air arrives Saturday night.

Sunday looks pleasant with mostly sunny to partly cloudy skies and
highs in the 70s. However, this will be short lived as onshore
flow quickly returns Sunday bringing moisture back across S tx
Sunday night Monday and increasing the rain chances across the
waters and into the eastern cwa. Model solutions diverge Tuesday
with the ECMWF bringing a weak frontal boundary through S tx on
tue while the GFS does not show any fronts until wed. With
uncertainty with timing strength of fronts and upper disturbances
by mid to late next week, kept pops on the low end and kept close
to the superblend output.

Fire weather...

drier and breezy conditions across the rio grande plains and brush
country in the wake of Saturday's cold front may lead to elevated
fire weather conditions in the afternoon.

Marine...

a weak to moderate northeast flow will continue over the coastal
waters today with the frontal boundary remaining just east of the
offshore waters. The warm front is expected to move into the
coastal waters tonight and inland on Friday. With warmer air
moving into the waters behind the warm front, expect patchy fog
will form over the bays and near shore waters late tonight into
Friday. Isolated to scattered showers will be possible through the
period.

Onshore flow is expected to strengthen Friday night ahead of a
cold front. Winds may approach advisory levels Friday night,
especially across the offshore waters. The cold front is expected
to move across the waters Saturday morning or early afternoon
with a weak to moderate offshore flow developing in its wake. Weak
to moderate onshore flow quickly returns Sunday and continues
through Monday.

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.
