Discussion Updated for latest aviation discussion below.
Aviation Vfr conditions tonight. May see brief MVFR ceilings
mid Wednesday morning, then scattered to brokenVFR skies with
moderate to breezy southeast winds by Wednesday afternoon. The
ecmwf and NAM support isolated convection on Wednesday, but the
gfs is drier. Much will depend on the moisture supply moving up
and in from the gulf.

short term (now through Wednesday night): the kbro upper air
sounding from around sunrise this morning indicated a precipitable
water value of 2.02 inches (an increase from 1.28 inches 24 hours
earlier), and as a result, isolated showers have broken out along
the sea breeze boundary and east of the interstate 69c corridor.
Streamer shower activity will affect the lower texas coastal
waters tonight, and with deep tropical moisture remaining in
place, similar conditions to today and tonight are anticipated for
Wednesday and Wednesday night. Unfortunately, not enough clouds
and precipitation will exist to prevent temperatures from reaching
well above normal values.
Long term (Thursday through Tuesday): the deep tropical moisture
present during the short term portion of the forecast will wane
during the long term portion, with precipitable water values|
decreasing to, and persisting near, the 1.50 inch mark instead of
the 2.0 inch value. Simultaneously, broad 500 mb high pressure
centered over the southern half of the four corners region will
build farther south and southeast. This pattern will prevent any
convection for the inland areas, with the only possibility of
convection being over the adjacent coastal waters Sunday night
through Monday night. Above normal daytime highs and overnight
lows will continue to be the rule.
Marine (now through Wednesday night): surface high pressure
centered over the southern portion of louisiana will provide
generally moderate winds and seas along the lower texas coast
during the period. Small craft exercise caution and small craft
advisory are not likely to be needed.
Thursday through Tuesday: surface high pressure will continue to
be the dominant feature over the western gulf of mexico, with
continued mainly moderate winds and seas for the lower texas
coastal waters. Small craft exercise caution and small craft
advisory continue to be unlikely for this period.

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 L-36.com 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.
