Synopsis for the middle texas coastal waters.. A moderate northerly wind and occasional rain showers can be expected through the afternoon. The offshore flow is expected to increase to moderate to strong over the gulf waters late tonight into Tuesday. With the front moving farther offshore Tuesday, rain chances will decrease. A coastal trough will then lift north across the western gulf of mexico Wednesday. This will increase the chance for showers, along with weak to moderate east to northeast flow. Rain chances will gradually diminish Thursday and Friday as the coastal trough moves east.

Discussion See aviation section for 12z tafs.

Aviation Low stratus and fog blankets south texas early this
morning behind the cold front, now located well offshore of the
middle texas coast. Lifr ceilings and ifr vsbys will remain
prevalent over the region through 16z along with intermittent
light drizzle, except for the northern brush country where
ceilings and vsbys will be MVFR. Scattered light showers will be
possible over the coastal plains this morning also. Went with the
nam regarding slow improvement with regards to ceilings, lifting
to ifr around 16z with vsbys improving toVFR. Ceilings should
lift to MVFR by late this afternoon. Drier air in the lower levels
will move into the vct area late this evening with ceilings
lifting toVFR around 08z. MVFR ceilings will be prevalent for
coastal bend into the brush country with ifr ceilings redeveloping
near lrd overnight.

Previous discussion issued 421 am cst Mon nov 19 2018
short term (today through Tuesday)...

the cold front has pushed into the offshore waters early this
morning. Satellite imagery shows an upper level jet streak moving
across northern mexico into south texas. Lift associated with weak
upper level divergence from this upper level jet, along with some
isentropic upglide in the 290-300k layer, will keep a chance for
showers over the coastal plains this morning. Lift will diminish
by the afternoon hours and will show rain chances decreasing to
slight chance. Patchy fog will also continue this morning. Diurnal
range will be small today with temperatures only expected to rise
to the mid to upper 50s.

As the upper level jet streak moves off to the east tonight and
another short wave trough drops down into north texas, high
pressure will build to the south and continue to push the cold
front into the northwest gulf of mexico. Winds will increase near
the coast late tonight into Tuesday morning. Isentropic downglide
will lead to decreasing clouds from the north on Tuesday. Even
though high pressure will be building into the area on Tuesday,
warmer temperatures are expected as clouds clear more sunshine.

The highs will be in the lower to mid 60s but still well below
normal.

Marine...

the cold front, located over the extreme eastern portion of the
offshore waters early this morning, will continue to push to
the southeast into the northwest gulf of mexico. North winds will
become moderate today over the gulf waters leading to scec
conditions. Scattered showers will be possible today for all
marine areas with rain chances diminishing to mainly over the
offshore waters tonight. Drier air will work its way into the
region for Tuesday with only a residual slight chance of showers
possible over the offshore waters. It appears the gradient will
strengthen later tonight, as high pressure continues to build
into south texas, and push the winds to SCA levels during the
overnight hours and linger into the afternoon hours on Tuesday.

Northeast winds will become weak to moderate Tuesday night before
restrengthening to moderate to strong levels Wednesday and Wednesday
night. Winds will gradually decrease through Thursday and then
become offshore Friday.

Long term (Tuesday night through Sunday)...

surface high pressure begins to shift slightly to the east Tuesday
night as a mid-level shortwave moves in from the west toward west
texas and the panhandle. This will allow for the inverted trough at
the surface across the western gulf to gradually lift back to the
north and settle along the texas coast. Moisture will gradually
increase returning rain chances Wednesday to south texas, especially
across the coastal bend to victoria crossroads and across the gulf
waters. With sufficient isentropic lifting out west, will continue
slight to low chance pops for the western brush country.

The mid-level shortwave is then expected to dive to the southeast
toward southeast texas and louisiana which will help absorb and lift
the coastal trough to the east Thursday, gradually tapering off rain
chances from west to east, with mainly slight to low chances of
showers across the gulf waters Thursday and Thursday night.

However, a longwave trough is then prog to move across the central
plains Thursday night and Friday prompting a weak front to quickly
move through south texas Friday, leading to a slight chance for
showers. Working with limited moisture, only expect showers mainly
across the eastern half of the cwa. It is after this boundary that
models begin to diverge on how fast south texas will dry out, with
the ECMWF drying things faster than the gfs. The models also differ
on timing of the next front over the weekend, where the GFS has a
faster approach Sunday morning, while the ECMWF is more toward
Sunday evening. For now, with limited moisture from the gfs, will
trend on the drier side similar to the ecmwf. Will take a blend of
timing of the front for during the day on Sunday.

As for temperatures, temperatures will gradually warm in the long
term, reaching into the low to mid 70s Friday and Saturday, cooling
behind the Sunday front with highs currently for Monday in the 60s.

With uncertainty in models later in the period, would not be
surprised to see changes in the coming forecast packages for this
late weekend and early next week.

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.
