Under mostly sunny skies with a gentle to moderate easterly
breeze, temperatures in the Florida Keys are at or just above 80
degrees. KBYX Doppler radar shows weak and widely-spaced isolated
showers pushing westward through the Atlantic waters well south
and southwest of the Lower Keys.

No significant changes through the coming week were evident in the
latest runs of the GFS and ECMWF models. Expect the local
conditions to be driven by high surface pressure maintaining a
westward extension across the Florida peninsula from the western
Atlantic. The mid level ridge will remain prominent from the
southern Gulf of Mexico across the southern half of the state and
into the Atlantic. Moisture will remain relatively limited for
this time of year, and confined below deep, dry, and stable mid 
levels. The local area will remain several degrees above the
average for this time of year. Will keep the probability of
measurable precipitation out of the forecast tonight through the 
first half of the weekend, and only hold on to just a slight
chance Saturday night through the balance of the forecast, thanks
to a slightly veered profile but with little else focusing
precipitation. In all, there is no reason to deviate much from
what we have been advertising over the past several days on the
upcoming forecast. 


Expect gentle to occasionally moderate breezes favoring the
easterly direction over the next several days across all waters
surrounding the Florida Keys. Recreational boating conditions are
expected to remain relatively pleasant for the next couple of 
days. Enjoy. 


VFR will prevail at the EYW and MTH terminals through the evening.


February 15th, on this date in Key West climate history, in 1985, 
the daily record low temperature of 49F was recorded. Temperature 
records in Key West date back to 1872.
