Update
The region will be between high pressure to the southeast, and a
trough to the north today. This will provide a general west to
southwest flow over NE fl into the afternoon, helping to keep the
east coast sea breeze near the coast. With this flow moisture
will increase from the gulf with convection spreading from
southwest to northeast later this morning, with convection also
developing along the east coast sea breeze. During the mid
afternoon convection will spread over central portions of NE fl,
then dissipating later in the afternoon. With a fairly light flow
expected today, localized heavy rainfall will be expected. A
little drier flow over SE ga will limit convection there to a more
isolated to scattered coverage.

Aviation
Convection is expected to develop this morning, with scattered
to numerous convection through the afternoon. Brief restrictions
in and near storms will be possible.

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.
