Area Forecast Discussion
National Weather Service Key West FL
910 PM EDT WED SEP 28 2016

Winds across the Keys and coastal waters are very light out of the
west, becoming variable at times. Skies are clear overhead, with
infrared satellite imagery showing only some cirrus off to the
northwest. Key West radar is not detecting any precip within our area
of responsibility. The evening sounding showed below normal
precipitable water at 1.7 inches and no near saturated layers in the
boundary layer.

Given current conditions and current trends, precipitation overnight
does not seem likely. There is also nothing upstream that would
change persistence overnight with the possible exception of some
cirrus moving in towards daybreak. Currently carrying slight chance
PoPs over the entire area, and out of respect for water temperatures
in the mid 80s and nocturnal marine boundary layer instability, will
only decrease that overnight to low slight chance, even though it is
very likely overdone. However, lightning will be removed for the
overnight period.


Light westerly to variable breezes are expected overnight. These is a
slight chance of showers overnight and through Thursday morning.


VFR conditions will prevail at both the Key West and Marathon
terminals overnight and through Thursday morning. Surface winds will
be mainly light and variable, becoming light out of the northeast to
east on Thursday.
