With the mid level trough moving away to the northeast this
morning, a more stable airmass is expected for this afternoon.

However, diurnally generated convection will initiate this
afternoon starting along the gulf coast sea breeze, with isolated
to scattered storms expected across the forecast area.

Temperatures will rise to above normal levels. Anticipate readings
to be just below heat advisory criteria.

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.
