Discussion Updated for latest aviation discussion below.

Aviation The combination of an approaching mid level low and
increasing low level moisture courtesy of a coastal trough across
the gulf will support overcast skies with MVFR ceilings, possibly
dropping to ifr lifr overnight, especially near the coast. Some
reduction in visibility will be possible in periods of light
rain or drizzle. Generally light to moderate northwest winds are
expected through the next 24 hours.

Prev discussion issued 256 pm cst Wed nov 13 2019
short term (now through Thursday night): surface layer air mass is
modifying, resulting in slowly warming weather and temperatures. A
low latitude mid level low is to the west over chihuahua, mexico,
moving slowly east. Ample upper cloud cover is seen on satellite in
the southwest flow setting up over deep south texas. Supplemented by
low clouds locked in by a still strong inversion, skies will remain
overcast tonight with low temperatures mainly in the 40s.

The trend for the next two days will be increasing rain chances as a
weak coastal trough develops, a reinforcing high pressure pushes in
from the north, and as the aforementioned mid level feature moves
overhead from the west. Most of this rain activity will be focused
over the marine and coastal areas due to the convergence of the
above listed features, with somewhat lesser activity over western
sections. Rainfall amounts will generally be light through 36 hours,
with weak overrunning generating lift over a still relatively stable
lower layer.

Continued cloud cover in the short term will result in retarded
warming, with overnight low temperatures in the 40s, though
tomorrow's high temperatures will rise about 10 degrees, into the
50s and lower 60s. However, this will still be around 5 to 10
degrees below normal for this time of year.

Long term (Friday through Wednesday): the upper level trough
exiting across the gulf of mexico gets pulled into the larger
trough across the southeast as high pressure builds across deep
south texas Friday into Saturday. This helps bring back warming
temperatures for the weekend, into the mid 70s by Sunday, yet
still below normal for mid november.

Quick moving frontal boundary arrives Sunday evening with little
fanfare at this point. Any rainfall would likely be limited to the
coast as the trough axis moves offshore. Temperatures into Monday
fall a few degrees from Sunday with a northwestern flow behind
the front, still reaching into the 70s for most. Normal to
slightly above normal temperatures arrive Tuesday into Wednesday
as high pressure builds and southwesterly flow aloft returns.

Marine (tonight through Thursday night): marine conditions will
worsen Thursday into Thursday night due to reinforcing high
pressure and weak coastal troughing. North to northeast winds will
increase Thursday, with small craft should exercise caution
conditions transitioning into small craft advisory conditions
Thursday night. A mid level disturbance moving over the area will
also contribute to increased rain chances.

Friday through Wednesday: as the upper level trough exits
northeast across the gulf of mexico and the pressure gradient
begins to weaken, moderate northerly winds diminish Friday into
Saturday, turning more onshore from the east and southeast. This
will allow any ongoing small craft caution or small craft advisory
conditions to subside. Marine conditions become quite favorable
Saturday afternoon into Sunday evening before a quick moving
frontal boundary brings moderate northerly flow back to the lower
texas coastal waters. Small craft caution conditions are possible
Sunday night through Monday. High pressure and lighter winds
return Tuesday, becoming moderate from the southeast on Wednesday,
with generally favorable seas expected.

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.
