Area Forecast Discussion
National Weather Service Key West FL
411 AM EDT MON JUN 20 2016

.DISCUSSION...
A few showers have been moving to the southwest in the vicinity of
the lower Keys early this morning. A few lightning strikes have
accompanied the stronger cells. Otherwise, skies are partly cloudy,
with temperatures in the lower 80s along the island chain. Winds at
the CMANs nearby have surged to near 20 knots, but these higher winds
have not generally been felt at the lower sensors along the island
chain.

A large area of high pressure currently centered over South Carolina
will settle south/southeastward today and tonight. Ridging in the
mid and upper levels will nose in the same direction, pinching off a
retrograding cyclonic gyre through the southern Gulf of Mexico
through that time. We expect breezy conditions to continue through
today and tonight thanks to the tightening surface gradient nearby.
Confidence is not the greatest in pinning down the exact wind speeds
since both the GFS and ECMWF have been oscillating over the past few
cycles. The smaller scale HRRR has been consistent with the more
robust winds surging across the local area today. A very recent
observation at the Key West weather office is more in line with the
higher marine observations, gusting to above 21 knots. So have better
confidence with a breezy descriptor for at least today and tonight,
with moderating conditions as the high surface pressure settles
further south/southeastward. Deep layered ridging will set a deep
east/southeasterly flow in place from the middle of the week into the
coming weekend. The GFS is sliding drier air aloft through the mid
levels beginning Thursday, hence its latest MOS numbers are
diminishing our chance of measurable rain for several periods later
this work week. For now, will keep a low chance of showers with
isolated thunderstorms advertised through the entire forecast.

&&

.MARINE...
Confidence is not the greatest in regards to the expected winds over
the next couple of periods. All marine observations, to include a few
recent ship reports, are showing surging winds across most of our
marine service area. Initially was thinking of capping conditions at
an exercise caution level for the nearshore Gulf and Bay waters. But
the reports for LONF1 over the past few hours prompted me to include
all waters surrounding the Keys under the Advisory for small craft.
Some of the marine zones surrounding the Keys may need to have that
extended through late this evening or even into the overnight
periods. But, boaters can expect moderating conditions through the
middle of the week as an axis of high surface pressure settles across
the Florida peninsula.

&&

.AVIATION...
VFR conditions will prevail most of today for the EYW and MTH
terminals. Northeast to east winds of 5 to 10 knots will increase
today to around 15 knots and gusty. Showers and possibly a few
thunderstorms will affect the terminals from time to time, mainly in
the afternoon and these will be addressed with amendments as
necessary. Cloud bases will range 020 to 025.

&&

.CLIMATE...
On this date in Keys weather history, in 2011, the low temperature
in Key West only dropped to 83 degrees, setting a daily warm low
record. Temperature records for Key West date back to 1872.
