Update
Dry air and subsidence aloft resulted in very low chances of
convection again this afternoon and early evening. A few weak
showers developed along the east coast sea breeze, where moisture
was pooling along the boundary, early in the aftn but weakened
before producing any lightning and additional convection toward the
inland areas. West coast and sea coast sea breezes now pushing well
inland with airmass too dry to produce any deep convection. Overall,
mostly clear tonight except for a few clouds clouds inland, and
along the coast where low level convergence may produce areas of
partly cloudy skies after about 4 am. A few showers will be possible
overnight over portions of the coastal waters in weak convergence
lines some enhanced moisture offshore, which could brush the beaches
around sunrise. Lows tonight not as cool as last night but 60s are
expected inland and closer to 70 near the coast. Some patchy fog
possible as west coast sea breeze advected low level moisture into
the suwannee valley.

Forecast on Monday on track, with continuation of hot temps again,
about 2-4 deg above normal, with silent (10%) pops in the forecast.

Temps will only continue to trend warmer rest of the week as ridge
builds aloft.

Aviation
PrevailingVFR expected through Monday. A few low clouds possible
through Monday for coastal tafs, and while MVFR is possible, the
chances are too slim to include any tempo group. South to southeast
winds will diminish overnight. East to southeast winds again on
Monday by the late morning and aftn with highest winds for coastal
tafs from east coast sea breeze near 8-12g18kt.

Marine
South to southeast winds near 10-15 kt expected overnight with seas
around 2-4 ft. Current forecast on track with little change.

Rip currents: a low to low-end moderate risk due to predominate
southeast winds and small long period swells through Monday.

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.
