Discussion
Data from the key west morning radiosonde balloon indicated a
moderately unstable atmosphere with less convective inhibition
energy than observed yesterday. However, considerable dry air was
present from about 5000 feet elevation upward. Surface
observations this morning reveal a few more cumulus clouds than in
recent days, and key west doppler radar scans even show a few
low-topped showers across the service area. Dry air at low
altitudes is the limiting factor for initiation of deep cumulus
convection right now, and that does not look likely to change much
during the afternoon. Therefore, the coverage of rain showers this
afternoon should remain isolated with the chance for measurable
rain at any one location at 10 percent or less.

Currently, air temperatures in most keys island communities have
reached the mid 80s, with afternoon highs once again likely to
range from 85-90f, depending on your exact location and exposure.

Dewpoint temperatures are holding steady in the mid 70s, and winds
are blowing from the east-southeast near 10 mph.

Marine
Southeast winds will range between about 10 and 15 knots this
afternoon across florida keys coastal waters, with significant
wave heights generally in the 1-3 feet range. Highest wave heights
will occur in the straits of florida. A developing low pressure
area across portions of the southeastern united states will induce
a veering and freshening breeze (ese to sse) tonight through
midday Tuesday. A brief lull Tuesday afternoon through early
Wednesday will be followed by freshening southerly breezes and a
stormier period Wednesday night and Thursday, in advance of an
approaching trough at the southern end of a more robust,
springtime storm system.

Aviation
Until 00z/23rd,VFR conditions will prevail at the island terminals.

East to southeast winds of 10 knots or less can be expected at the
island airports.

Climate
In 1940, the daily record low temperature of 68 degrees was last
recorded in key west. Temperature records have been kept since 1872.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
