Area Forecast Discussion
National Weather Service Key West FL
329 PM EST Thu Nov 24 2016

.DISCUSSION...
Currently - A high pressure system off the Georgia Coast and lower
pressure in the western caribbean is producing moderate to fresh
northeast to east breezes across the Florida Keys and surrounding
waters. Despite quite stable conditions with a strong inversion
around 800 and 850 mb, a mesoscale channel of confluent flow induced
a swath of showers and cloud cover through the day. Most of this has
finally dissipated and skies are clearing showers are becoming
sparse and weaker. Day time highs were able to get near 80 degrees
with dew point temperatures around 70.

Forecast - Moderate to fresh breezes will edge slowly downwards over
the next couple of days as the high cell to our north shifts eastward
and weakens. Ridging aloft will prevent deep convection, however
there is enough head room under the inversion to allow for isolated
shower activity. Expect slightly above normal temperatures.

The remnants of a cold front will move through South Florida and the
Keys during the middle of the weekend. This will be moisture starved
and without support either aloft or at the surface. Temperatures will
only dip to near normal, dew points however, will drop into the 60s.
Winds will gradually edge upwards through the back half of the
weekend as a new high cell moves into the southeastern United States.
Rain chances will be slim to none through this period and into early
next week.

The new high cell will spread into the Atlantic resulting in winds
strengthening further while veering east to southeast through the
first half of the upcoming week. Expect temperatures and moisture to
trend upwards to above normal. Rain chances will also begin edging
upwards due to the increased moisture and the ridging aloft shifting
east of our area.

&&

.MARINE...
High pressure to our north will gradually weaken and shift further
out into the Atlantic over the next couple of days. In the mean time,
cautions remain in effect for portions of Keys Waters, and a period
of advisories are possible. Winds will pick up again beginning late
Saturday as a new high cell moves into the southeastern United
States. Cautions and advisories will likely be required for portions
of Keys waters through the first half of next week.

&&

.AVIATION...
Generally VFR conditions through the period. Isolated very light
showers will occur through at least mid afternoon...and will place
VCSH in the TAFS. East winds 10-13 knots expected today with gusts
15-18 knots at times this afternoon. Winds are expected to be
slightly higher on Friday. Periods of BKN ceilings expected through
Friday morning but ceilings expected to remain above 3000 feet.
