Area Forecast Discussion
National Weather Service Key West FL
401 AM EDT Sat Sep 23 2017

.DISCUSSION...
.CURRENTLY...
Some showers are moving southeast across the Keys area at this
hour. Winds are out of the northeast at 5 to 10 knots at the
island terminals, and near 10 knots at the marine reporting
stations.

.FORECAST...
A weak pressure pattern will continue for the weekend due to Maria
east of the Bahamas, and high pressure to the north. Cyclonic flow
aloft with light easterly flow in the low levels, and ample
moisture would suggest at least a high chance of showers. The only
thing lacking is a good lifting mechanism. Any lifting that
occurs will be in the guise of lingering, or propagating outflow
boundaries off activity from the Florida Peninsula or Cuba. No
changes will be required in this forecast cycle.

&&

.MARINE...
No advisory or cautionary statements are expected through
Thursday. Outside of scattered showers and isolated thunderstorms,
breezes will remain light to gentle and mainly out of the
northeast.

&&

.AVIATION...
Today, VFR conditions will prevail at both the EYW and MTH Int`l
terminals. After 16Z, scattered showers and isolated thunderstorms
may impact either/both terminals with short lived MVFR/IFR cigs
and/vis. Winds will be light and north to northeast from the surface
to about FL080-100.

&&

.CLIMATE...
In Keys Weather History, 1874, the low temperature in Key West
fell to 71 degrees. This set the daily record minimum temperature
for Key West on September 23, which stands 143 years later.
