.Short term (today through Tuesday): an initially zonal 500 mb flow
over deep south texas and the rio grande valley will become more
oriented out of the southwest as closed mid-level low pressure
pushes into the four corners area. However, despite a breezy to
windy onshore flow off the adjacent lower texas coast, not enough
moisture and instability will exist to produce precipitation during
the short term forecast period. The onshore flow will also help to
reinforce well above normal temperatures through the 36-hour

.Long term (Tuesday night through Sunday): 500mb low/trough across
the southwest united states/northern mexico Tuesday will move
eastward across the southern plains Wednesday. Low to mid level
moisture will increase across east texas towards the coastal bend
tues night into Wednesday and convection will develop across
portions of west and southwest tx tues night and move eastward
across portions of central and south-central tx Wed morning. The
best rain chances will remain northeast of the CWA through
Wednesday but will mention a slight chance of showers and
thunderstorms across northeast portions of the cwa. Until the
upper level trough moves through the state Thursday... Isolated
showers and thunderstorms will develop across portions of south tx
through Wednesday night. 500mb ridge across west tx Thursday will
provide subsidence across south tx Thursday and Friday before the
next 500mb low/trough moves eastward across southwest
u.S./northern mexico Saturday producing a slight chance of showers
and thunderstorms across the area through the rest of the
forecast period.

.Marine (now through Tuesday): buoy 42020 reported south winds
around 16 knots gusting to around 19 knots with seas slightly over
5.5 feet with a period of 7 seconds at 02 cdt/07 utc. High pressure
and low pressure interaction will produce breezy winds and rough
seas along the lower texas coast during the period. Small craft
exercise caution and small craft advisory are likely to be needed.

Tuesday night through Friday... Moderate to strong southeast winds
will prevail across the coastal waters tues night into early Wednesday
as low pressure across the texas panhandle provides a strong
pressure gradient across the lower tx coast. Small craft
advisories will be needed for the coastal waters tues night
through Wed morning. The pressure gradient will relax wed
afternoon as a weak cold front approaches the coastal waters.

Winds will diminish Wed afternoon into Wed evening as a result.

Moderate southeast winds should prevail across the western gulf of
mexico Wed night before a weak cold front moves offshore the
lower tx coast Thursday. Light northerly winds Thursday will veer
to the east thurs night and southeast Friday as high pressure
across the northwest gulf moves eastward.

There are five sources. 1) Documents and manuals from a variety of sources. 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.
