Synopsis for the middle texas coastal waters.. Moderate north to northeast flow this morning will weaken through this afternoon. Winds will briefly veer to the east to southeast tonight, but another surge of high pressure will shift the winds back to the northeast on Friday. A weak reinforcing ridge of high pressure will move into the coastal waters Saturday morning for a brief period of northeast winds. The winds are expected become onshore by Saturday afternoon. The onshore flow will strengthen to a moderate flow on Sunday into Monday as a trough of low pressure forms over the southern high plains.

Updated for the 12z aviation discussion.

Lingering MVFR CIGS at lrd to continue through late morning,
lifting toVFR after 18z. Otherwise,VFR for today, with bkn sct
cigs around 4k-5k ft. N-ne wind around 10 kts to gradually become
e-se during the afternoon. Should see a return of NE wind
overnight for ali-crp-vct.

Previous discussion issued 413 am cdt Thu apr 26 2018
short term (today through Friday)...

the mid-level trough continues to move east across the southern
states while the surface cold front moves further from shore. Weak
isentropic lifting across the southern brush country may lead to a
few sprinkles, but should only be brief this morning as the h85
front continues to slide further south. Surface high will build in
through today and then quickly shift east, with breezy northerly
winds this morning expected to weaken and gradually take on an
easterly component this afternoon. And with cooler and drier air
filtering into south texas, today will be one nice spring day.

Cool conditions can be felt tonight with lows dipping into the
lower 60s along the coast and across the rio grande plains, while
lows will dip into the mid to upper 50s from near tilden and east
toward the victoria crossroads.

Another frontal boundary will move through on Friday with winds
backing out of the northeast. The return moisture is rather
limited, but there may be sufficient moisture across the southern
brush country to squeeze out a few showers. Otherwise, warmer
conditions are expected for Friday, with highs in the low 80s.

Long term (Friday night through Wednesday)...

a weak reinforcing ridge of high pressure will settle into mid-coast
region late Friday night into Saturday morning. This will push the
low level moisture axis into northeast mexico to near the rio
grande. Gfs ECMWF suggest a weak short wave trough will move out of
northeast mexico into south texas Saturday morning. Will keep a
slight chance of convection over the southern brush country Saturday
where the higher low level moisture will be.

An upper level ridge will move across the region Saturday night into
Sunday with the higher moisture remaining in mexico. Will keep the
forecast dry for Sunday. Onshore flow will increase on Sunday as low
pressure trough strengthens lee of the rockies in advance of the
upper trough moving into the western us. Enough moisture will return
by Monday for a slight chance of convection. An upper low is
expected to dig south through the great basin Tuesday with the low
moving out across the four corners region Wednesday. Weak
disturbances in the southwest flow aloft across mexico into south
texas could lead to better chances for convection across the
northern coastal bend into the victoria crossroads Tuesday and
Wednesday. Moderate to strong onshore flow will be possible over the
coastal waters both days.

These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
