Area Forecast Discussion
National Weather Service Key West FL

.DISCUSSION...
.CURRENTLY...
Despite considerable translucent cirrus covering our region, skies
are partly cloudy with temperatures in the lower to mid 80s along
the Florida Keys. Meanwhile, local radars are only detecting
isolated showers in our county warning area. Surface wise, a
western Atlantic ridge axis remains anchored across the Florida
peninsula and it extends well into the Gulf of Mexico. On our
marine district, southeast winds are hovering around 10 knots.

&&

.SHORT TERM...(Today through Wednesday night)
Little change in the overall pattern with a modest low and mid
level ridge lying across the Sunshine state, with an occasional
subtle low level perturbation accompanied by higher moisture
passing through our region. Hence, isolated 20 percent pops will
be retained through tonight with low chance pops thereafter until
timing and confidence increases. High temperatures will average in
the lower 90s with overnight lows between 80 and 85 degrees.

&&

.LONG TERM...(Thursday through Saturday night)
Our area will lie on the western edge and southern periphery of
the subtropical ridge, resulting in light to gentle east to
southeast winds. Given a decoupled flow and no significant low
level trough or large scale ascent, low chance pops which are
average for this time of year will be maintained. Highs will poke
into the lower 90s with overnight lows in the lower to mid 80s
away from any downpours.

&&

.MARINE...
Outside of any possible showers, outflow boundaries or
thunderstorms, light to gentle mostly southeast winds
will prevail on Keys coastal waters for the balance of this
weekend and well into next week.

&&

.AVIATION...
Today, VFR conditions are expected at both the KEYW & KMTH Int`l
island terminals. Very brief isolated showers could impact
either/both terminals but probability way to low to include a VCSH
or a tempo. Surface winds will average from 110-140 degrees at 7-10
knots with a few to scattered clouds at FL020-025 & FL050
respectively.

&&

.CLIMATE...
In 1921, the daily record low temperature of 71 degrees was last
recorded in Key West. Temperature records date back to 1872.

&&

.PRELIMINARY POINT TEMPS/POPS...
Key West  91  83  91  83 / 20 20 30 30
Marathon  91  82  91  82 / 20 20 30 30
