Marine Weather and Tides
Aransas Pass, TX

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

short term (tonight through Thursday night)...

scattered showers and thunderstorms continue to fill in across
the victoria crossroads this afternoon and are expected to linger
through the mid-evening hours before dissipating from loss of
heating. SPC mesoanalysis shows very light winds in the cloud-
bearing layer (850-300 mb winds less than 10 mph), which is
resulting in very slow storm motions this afternoon and allowing
localized areas to pick up a quick 1-1.5 inches of rain before
thunderstorms dissipate. Drier conditions are expected to settle
in by late evening inland with little more than a few streamer
showers across the coastal waters.

Good radiational cooling and light will promote another round of
patchy fog overnight generally along and east of the highway 281
corridor with morning lows in the lower to mid 70s. Any fog that
develops is expected to lift quickly after sunrise. Another round
of diurnally driven showers and thunderstorms will be possible
again Thursday as highs climb into the upper 80s to mid 90s, but
anticipate lower coverage than what was observed today with a
compact shortwave drifting farther east of the middle texas coast.

Dry conditions are expected again Thursday night.

Long term (Friday through Wednesday)...

upper ridging nosing north into west texas out of mexico and
wobbling east will result in dry and hot conditions becoming
established across the region during the long term portion of the
forecast. Subsidence associated with this ridging will contribute
to high temperatures rising near or above 100 degrees by late
weekend across the rio grande plains with weak onshore flow and
potential daily sea breeze development moderating temperatures
into the upper 80s to mid 90s closer to the coast by the end of
the forecast.

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.
