Discussion
Currently
Under variably cloudy skies, temperatures range from the upper 80s
to near 90 degrees along the florida keys. Meanwhile, local radars
are detecting widely scattered showers and a few thunderstorms on
the waters south of the island chain, with only isolated showers
along and north of the florida keys. Surface wise, a weak tropical
wave is located on the western half of our county warning area
with high pressure to the north. Winds are mostly east at 10 to 15
knots across our marine district.

Short term (tonight through Wednesday night)
in wake of the weak tropical wave, some drier air will filter into
our region through Monday, before moisture and low level
confluence increases with an approaching tropical wave thereafter.

Therefore, outside of isolated pops on Monday, the decelerating
second tropical wave will become nearly stationary somewhat in the
extreme southeast gulf of mexico. Hence, this will prompt
increasing chance pops to be retained through the period.

Long term (Thursday through Sunday)
see no reason to stray from middle of the road chance pops with
high temperatures in the lower 90s and overnight lows in the lower
to mid 80s away from any possible downpours.

Marine
A wind surge will overspread our entire marine district, hence, a
small craft advisory will be in effect for the straits of florida
and an exercise caution headline elsewhere tonight. Winds will
slacken slightly by Monday afternoon before another minor increase
affects our coastal waters late Monday. Beginning Tuesday
afternoon and likely persisting through the balance of this week,
light to gentle southeast to south winds will prevail.

Aviation
Scattered showers and a few thunderstorms will persist through early
this evening. Will keep vcsh in the tafs through 00z. The potential
exists for a brief periods of wind gusts 20-25 knots, visibilities
of 2-4 miles, and MVFR ceilings if heavier showers impact the
terminals. The atmosphere will dry out later for tonight and Monday
resulting in much less coverage of showers during this period.

Generally expectVFR conditions outside of shower activity with
winds east around 10 knots with occasional gusts up to 20 knots.

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.
