Area Forecast Discussion
National Weather Service Key West FL
1036 AM EST Mon Feb 27 2017

.DISCUSSION...
.CURRENTLY...
Skies are partly to mostly sunny with temperatures already
hovering around 80 degrees. Meanwhile, local radars are only
detecting a few showers on the distant waters beyond 50 nm south
of the Lower Keys. Surface wise, a strengthening (1032 mb) ridge
axis extends across the southeast United States, resulting in
east to southeast winds of 14 to 18 knots on our marine district.
Otherwise, our morning sounding reveals scant moisture (pwat .88
inches) confined to below 850 mb.

&&

.SHORT TERM...(Rest of Today)
With our area on the southern periphery of a deep troposheric
western Atlantic ridge axis aligned across the south Florida,
large scale subsidence will persist. So despite weak upglide below
850 mb, scant moisture should limit any shower activity to
possibly the Florida Straits. Plenty of insolation within a
veering east to southeast flow, will allow high temperatures to
climb mainly in the lower 80s except 85 degrees at the Marathon
ASOS.

&&

.MARINE...
A Small Craft Advisory will remain in effect for the Florida
Straits, an Exercise Caution Headline for Hawk Channel and near 15
knots north of the island chain will be inserted.

&&

.AVIATION...


&&

.CLIMATE...
In 1989, the daily record low temperature of 46 was recorded in
Key West. Temperature records have been kept since 1872.

&&

.KEY WATCHES/WARNINGS/ADVISORIES...
FL...None.
GM...Small Craft Advisory until 5 PM EST this afternoon for
     GMZ052>055-072>075.
