Area Forecast Discussion
National Weather Service Key West FL
340 AM EST Wed Jan 18 2017

Under mostly clear skies, temperatures in the Florida Keys are in
the lower 70s. Winds have moderated from the east southeast, with
slightly higher breezes in the extreme southwestern portion of our
Atlantic marine the vicinity of a few very weak echoes
per KBYX doppler radar.

An area of high surface pressure will remain across northern
Florida today, then shift eastward tonight and Thursday. Under a
moderate and persistent mid to upper level ridge with a stable
and dry layer above limited low-level moisture, the chance for
measurable precipitation is quite low for the next several days.
No need to change a POP-free forecast through the remainder of
this work week and the first half of the weekend. Temperatures
will remain 5 to 7 degrees above normal with a gentle to
occasionally moderate east/southeast breeze in place.

A cold front will approach South Florida and the Keys late Sunday
and should be south of the Keys coastal waters by Monday evening.
Expect a chance of showers with a few thunderstorms Sunday night
and Monday, followed by seasonal temperatures and a few lingering
showers on the back side of the front.


Aside from some residual higher gusts in the extreme southwestern
Atlantic waters well south of the Dry Tortugas, winds are gentle
to moderate over the bulk of the service area. High surface
pressure in the region will allow for more agreeable recreational
boating in all coastal waters surrounding the Florida Keys for the
next several days. Freshening/strengthening south to southwest
winds will be realized during the day Sunday ahead of an
approaching cold front.


Expect VFR conditions to prevail at both the Key West and Marathon
International terminals through at least 19/06z. A few clouds may
pass by the approach around 2800 feet. Winds out of the east to
southeast will decrease through 18/18z.


On this date in Keys Weather History, 1899, 2.04 inches of rain fell
on Key West setting the daily record rainfall. This record stands
118 years later. Rainfall records for Key West date back to 1871.
