Marine Weather and Tides
Clear Lake Shores, 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.

Aviation
Tricky forecast with CIGS overnight, as well as development (or
not) of showers moving back into sern tx around persistent upper
low over south tx. High resolution guidance gives mixed signals
on redevelopment of shra or tsra tonight, and have opted to bring
vcsh back to lbx and gls after 08 09z. In addition, ifr scattered
to broken deck has developed at many sites late this evening and
may become predominate across most of our terminal forecasts
overnight and will have to follow these trends closely. Otherwise,
expect return to predominantVFR CIGS through the day tomorrow.

discussion...

south to north moving shower and thunderstorm areas are making
progress eastward this evening with the heaviest rainfall almost
out of our area. Beginning to see some slow warming on the ir
satellite imagery indicative of weakening activity.

Training storms continue across parts of south and deep south
texas around the circulation center with cloud tops beginning to
cool once again off the lower to middle coast. While this area
appears favorable as maybe the highest risk area overnight,
cannot rule out parts of our area as we remain along this
system's moisture axis. Rain chances remain in the forecast for
tomorrow followed by significant improvement (lower chances)
tomorrow night and Friday.

Summer official begins tomorrow morning at 507 am cdt.

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.
