Area Forecast Discussion
National Weather Service Key West FL
900 PM EDT Thu Jun 22 2017

.DISCUSSION...
There are only a few small showers currently in the Atlantic
waters adjacent to the upper Keys, moving to the west at 10 to 15
knots. Under partly cloudy skies elsewhere, temperatures along the
Keys island chain are in the middle 80s.

The evening local sounding shows a very deep east to southeast
wind profile, while moisture aloft and into the mid layers has
diminished over the past twelve hours. MIMIC imagery shows this
pocket currently encompasses the Keys and surrounding waters, and
much of south Florida. But, we should see at least a few shallow
showers through the overnight period. Temperatures should not
move very much from their present readings overnight, just like
the winds. So, no zone update is planned late this evening.

&&

.MARINE...
Small craft should exercise caution across the Straits of Florida
and the offshore Gulf waters beyond five fathoms. More gentle to
moderate breezes will persist across the remainder of the coastal
Keys waters. The upcoming coastal waters forecast will have no
changes from the afternoon package.

&&

.AVIATION...
Expecting VFR conditions to prevail overnight at both the Key West
and Marathon International. After 23/15 expect a slight chance of
showers crossing near either terminals, and have installed vicinity
showers in the TAF for this probability.

&&

On this date in Keys Weather History, 1901, the low temperature was
70 degrees and set the daily record for minimum temperature in Key
West on June 22nd. Temperature records for Key West date back to
1872.
