.UPDATE...

The forecast for tonight looks good. The only update was to tweak
hourly temps down a few degrees here this evening based on how
quickly temps have fallen off since sunset. In fact we are already
closing in on our forecast min temps. Temperatures, however, will
level off and are likely to even come up a degree or two after
midnight as warm air advection kicks in and high clouds increase
from the west. Southwesterly flow may also come up just a tad
during the early morning hours. Main forecast challenge is
determining extent of low clouds moving into portions of northeast
Florida from the Gulf of Mexico late tonight. Should see skies in
our southern zones become at least partly cloudy if not mostly
cloudy by sunrise.

.AVIATION...

VFR conditions will generally prevail. The only question mark is
the potential for some low clouds moving in across portions of
northeast Florida from the Gulf of Mexico late tonight. Latest
forecast soundings and high res data lend enough confidence to
show MVFR ceilings at GNV an SGJ late tonight into Thursday.

&&

.MARINE...

SCEC looks good overnight into Thursday. Southwest winds will
steadily increase during the night and will approach 20 knots
over the offshore waters after midnight. Southwest winds will only
gradually subside during the day on Thursday.

Rip Currents: Low Risk.
