Discussion
Currently
Under variably cloudy skies, temperatures range from the mid 80s
along most of the lower keys to 75 to 80 elsewhere. Meanwhile,
local radars are detecting numerous showers and thunderstorms on
the nearshore gulf and florida bay, with isolated showers and
thunderstorms elsewhere. Surface wise, a weak tropical wave is
draped from south florida southward to the north coast of the
archipelago of cuba. Away from cells, mostly east winds are near
10 knots.

Short term (rest of today)
a weak tropical wave on the extreme western periphery of a large
mid and upper level low will track westward into the extreme
southeast gulf of mexico this afternoon and tonight. In wake of
this low level confluence and large scale ascent, drier air will
filter into our area along with an increasing easterly wind. With
that said, the probability of precipitation will drop sharply
this afternoon. Subsequently, an update will be sent later this
morning to reduce pops from likely to scattered. Under partly
cloudy skies temperatures will climb to near 90 degrees.

Marine
Away from showers, thunderstorms and outflow boundaries this
morning, activity will be on the decrease during this afternoon.

However, an easterly wind surge will gradually overspread our
entire marine district by late this afternoon and into tonight
when a small craft advisory exercise caution headline will be
needed for all keys coastal waters tonight.

Aviation
Scattered showers and isolated thunderstorms will
impact the terminals this morning and early afternoon. Have tempo
groups placed in the tafs through 19z. Brief periods of wind gusts
20-25 knots, visibilities of 1-2 miles, and MVFR ceilings can be
expected in the heavier showers. The atmosphere will dry out later
this afternoon and tonight resulting in less coverage of showers
during this period.VFR conditions and east winds 10-15 knots
expected outside of the shower activity.

Climate
In 1963, the daily record low temperature of 69 degrees was
recorded in key west. Temperature records have been kept since
1872.

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.
