Update
A weak cold front is very slowly settling southward through
the central florida peninsula. There is a defined dewpoint
gradient along this front, with middle 60s dewpoint south of
i-4... And dewpoints mainly in the 50s further to the north.

Within this post-frontal environment... A large expanse of
lower stratus is also evident on satellite this
evening... And should continue to expand southward into the
i-4 corridor through the rest of the evening hours. These
clouds will mainly be an impact to the aviation community.

A tightening pressure gradient along and behind the front
will also lead to choppy to rough conditions over the
eastern gulf of mexico... Mainly from the venice area
northward through the rest of the overnight and early
Saturday morning. Mariners should expect developing
cautionary level winds out of the east... With periods of
near advisory level winds to the north of tarpon springs.

Low temperatures overnight generally in the lower to middle
60s... With a few spots up toward levy county dipping into
the upper 50s toward sunrise.

Aviation (21 00z through 22 00z)
Main forecast concern for remainder of the evening and
overnight will be the evolution of a large area of MVFR cigs
to the north of the i-4 corridor. This region should expand
to the southwest after sunset, but confidence in its impacts
around ktpa kpie krsw are lower than average. Have included
MVFR conditions after midnight as these areas of lower
ceilings in NE flow tend to be more aggressive than most nwp
will show. Onshore W NW flow at 00z will shift back to NE e
after 03z with the decay of the seabreeze. Any early morning
MVFR CIGS lift to allow for a sct-bkn deck with bases above
4kft for much of the day. Sea-breeze development should turn
winds onshore along the immediate coast. A few showers along
this sea-breeze are possible inland... With klal seeing the
greatest potential for a later afternoon shower.

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.
