discussion...

surface high pressure has moved east this morning and southerly
winds should increase today. An upper level ridge was located over
the plains and texas this morning on the 12z analysis but this
ridge should flatten as a short wave strengthens across the
northern plains. Overall forecast looks on track but did go a
degree or two higher on MAX temps today with clear skies and warm
air advection beginning.

Next chance of rain looks on track for Thursday morning although
that chance of rain may linger more during the day if the upper
level low slows down a bit as the latest 00 06z guidance show.

We'll see if that trend continues with the 12z guidance.

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.
