Update
Early evening satellite imagery is showing a broad cyclone
over the central mississippi river valley, dragging a
cold front through the northern gulf coast. Currently,
florida resides in the fairly dry and stable airmass ahead
of this system, with a band of cumulus clouds lined up
along the sea breeze boundary along and west of interstate
75. This band has been producing a few isolated sprinkles
over southwest florida, but otherwise rain free conditions
will continue overnight. Surface dew points are high enough
that a few isolated patches of fog will not be impossible,
but the coverage and confidence is too low to mention in the
forecast at this time.

The bigger forecast concern will be what will happen as
that front approaches on Sunday. The GFS is generally more
aggressive than the ECMWF or NAM with holding the front
together and producing rain chances mainly over the nature
coast during the afternoon. The 18z GFS has not
significantly changed from what the 12z solution showed,
so no updates to the forecast are planned beyond the tonight
period for the evening update. The slight rain chances over
southwest florida for the rest of this evening have been
dropped. Otherwise only minor adjustments were needed for
the evening update.

Aviation
MainlyVFR conditions will hold through the next 24 hours.

The possible exception will be if some patchy fog or low
stratus develops late tonight and into early Sunday morning
creating brief periods of MVFR or ifr conditions, although
confidence is not high enough to include in the tafs at this
time. A stronger sea breeze circulation is expected Sunday
afternoon, potentially impacting a few more sites than it
did today by turning the east winds onshore.

Marine
High pressure centered over the atlantic will continue to ridge into
the eastern gulf through the weekend, as a weak front washes out
over the northeastern gulf on Sunday. The surface ridge will then
shift west towards florida through mid week, with light winds and
seas continuing.

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.
