Area Forecast Discussion
National Weather Service Key West FL
925 AM EDT Wed May 23 2018

KBYX is unavailable due to equipment issues. KAMX detects no
precipitation echoes in the forecast area. Skies over the island
chain are mostly cloudy. Winds over land are east to southeast
near 15 mph. C-MAN winds, on average, are east to southeast near
15 knots. Temperatures are near 80 degrees.

.SHORT TERM (This afternoon)...
In the low to mid levels of the atmosphere, an Atlantic ridge of
high pressure will extend across North Florida this afternoon. In
the upper levels of the atmosphere, a ridge of high pressure will
be located over the Florida peninsula today. The 12z KKEY sounding
is moderately unstable and quite moist for this time of year, with
a precipitable water (PWAT) value just above one and three
quarters of an inch. Atmospheric moisture will decrease this
afternoon. By sunset this evening, PWAT values will be just below
one and three quarters of an inch, which is still near the 75th
percentile for the latter half of May. Despite adequate
atmospheric moisture and instability in place for convection, lack
of an apparent convective trigger will limit POPs to low chance
category today.


Moderate east to southeast breezes will prevail on all Keys
coastal waters this afternoon. No advisories expected today
through at least Friday. A Small Craft Advisory may be required
for the coastal waters of the Florida Straits Friday night. A
Small Craft Advisory may be required for all Keys coastal waters
Saturday through Sunday night.


VFR conditions are expected, but occasional MVFR with any passing
shower will be possible through 24/12z at EYW and MTH. Expect
southeasterly flow sustained at 10 to 15 knots, with occasional
gusts near 20 knots this afternoon.


On this date in Keys weather history, in 1903, the Key West
Weather Forecast Office moved from the Waite building to the
Weather Bureau building at Front and Eaton streets (which is now
located within the Truman Annex). It was not until 2005 when NWS
Key West moved into its current location, at United and White
Street across from Key West City Hall.
