Update
Convection has already faded out for most the of the region, with
only some only a few lingering isolated showers remaining. Calm
weather is expected tonight through tomorrow morning, with mild
winds and high level clouds which should help to prevent
widespread fog from developing in the early morning hours. With
the ridging pressing in from the east moving to cover more of
northeast florida and southeast georgia, weather developments
tomorrow are expected to be scattered showers and potential
thunderstorms in the afternoon and evening.

Aviation
With the last of the vicinity thunderstorms north of kjax having
cleared for the evening,VFR conditions are expected to persist
throughout the forecast area into tomorrow morning. Mild overnight
winds with no significant fog developments are expected through
until tomorrow morning.

Marine
The lack of strong pressure features results in light winds and
shallow seas throughout this week. Another frontal feature
approaches the northern waters late this week into the weekend,
but uncertainty remains on how far south it pushes.

Rip currents: low risk of rip currents, with a minor increase
during the afternoon as the sea-breeze moves inland.

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.
