.DISCUSSION...
Amidst the elongated chaff echoes pushing across the Middle and
Upper Keys, there are a few widely spaced showers. Even weaker 
and more separated echoes are currently in the waters well south 
of the Marquesas Keys. Otherwise, under partly cloudy skies with a
gentle to occasionally moderate east to southeast breeze, 
temperatures along the island chain are in the mid 80s.

The evening local sounding shows the east to southeast gentle
breezes extend to just under 10000 feet, and then veered to 
southerly through the mid levels. Drier air has pulled in through 
that transitional layer, dipping the overall moisture in the
column to under 1.7 inches...markedly lower then this morning. A 
few stray showers are possible through the overnight period, but
they should remain widely spaced and relatively weak. The 
afternoon zone issuance has the sensible weather elements 
advertised well through the near term with no update necessary. 

&&

.MARINE...
Expect mainly gentle east to southeast breezes overnight into 
Wednesday. There will be little if any changes included on the 
late evening coastal waters update. 

&&

.AVIATION...
VFR conditions will prevail at both EYW and MTH terminals. Upper 
level and midlevel moisture will increase tomorrow morning and allow 
low level clouds to build into VCTS by the afternoon. Thunderstorms 
should diminish after the initial activity subsides and have 
included VCSH after 15/21Z.  Expect east to southeasterly surface 
winds between 9 to 12 knots. Southeast winds at FL 020 will increase 
to near 20 knots after 15/21Z. 

&& 

.CLIMATE...
In 1956, the daily record high temperature of 94 degrees was last
recorded in Key West. In 1958, the daily record low temperature 
of 71 degrees was last recorded in Key West. Temperature records 
have been kept since 1872.
