Discussion
Currently - a surface through lower level atlantic ridge extends
westward across the florida peninsula. This is resulting in gentle
east breezes across the keys this evening. Temperatures are, not
surprisingly, in the lower 80s with dew points in the mid 70s.

This evenings sounding indicated ample cape. However, there is
some inhibition and drier air at the lower levels. A few showers
were able to develop this afternoon. Since then, all activity in
the forecast area has dissipated. There are some cells between our
waters and andros.

Short term update - surface winds will remain gentle out of the
east through the overnight period thanks to the ridging to our
north. Back ground ridging and previously mentioned drier air and
some stable layers through the lower levels will keep, not
prevent, shower activity. Will maintain slight chance for showers
and thunderstorms. Expect temperatures to only fall a couple more
degrees if at all due to the decent ventilation.

Marine
Ridging across florida will keep gentle to moderate east breezes
across the keys through the overnight period. No changes made in
the evening marine update.

Aviation...

vfr conditions expected for the overnight. There is a slight chance
of showers moving across the terminals during the night but chances
are too low at this time to mention in the tafs. As it stands the
nearest shower activity is just off the andros island and decaying.

Otherwise, light east southeast winds around 10 knots through the
period.

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.
