.DISCUSSION...
.CURRENTLY...
Skies are mostly sunny to partly cloudy across the island chain,
but a broken line of pre-frontal showers and thunderstorms is
developing 50 miles to the west of the Dry Tortugas. Individual
cells within the broken line are moving northwest near 30 knots,
but the overall feature is drifting eastward near 10 knots, so it
will take several hours before these showers impact our western
marine zones. Temperatures are in the low to mid 80s, and dew
points are in the mid 70s. CMAN and Weatherflow stations report
southerly winds of 10 to 15 mph, with winds on land near 5 to 10
mph.

.SHORT TERM...
All eyes remain on the incoming cold front and powerful upper-
level trough behind it, which has brought freezing temperatures
and mixed precipitation to much of the northeast and deep south.
While that type of weather is not expected in the Keys, the front
will be quite strong for early December, bringing a round of
showers and thunderstorms tonight, another round with its passage
tomorrow, strong breezes and cold air advection behind the
boundary. Expect a drastic change in the weather behind the cold
front tomorrow, as temperatures drop into the 60s Saturday
afternoon, and within the 50 to 60 degree window Saturday night.

&&

.LONG TERM...
The effects of this cold front will have lasting power, as the 500
mb trough axis lingers through the spine of Florida before
flattening Monday. Tuesday night, a new cold-core low develops
across the great lakes, pushing another reinforcing trough (and
dry-frontal passage) through the Florida Keys. As a result,
temperatures late this weekend and early next week will average 5
to 10 degrees below normal, and conditions will be relatively dry.
Temperatures will begin to moderate back to climatological norms
late next week as the jet stream becomes zonal, lifting the trough
axis poleward.

&&

.MARINE...
A Small Craft Advisory is in effect for increasing winds in the
western Florida Straits and offshore gulf waters adjacent to
mainland Monroe County. Small craft should exercise caution for
increasing winds late tonight in the Florida Bay, Bayside/Gulfside
waters, Hawk Channel and eastern Florida Straits. A strong cold
front is expected to cross the Florida Keys Saturday morning,
bringing strong breezes and building seas to all coastal waters
Saturday. A Small Craft Advisory will likely be needed for all
coastal waters surrounding the Florida Keys Saturday into Saturday
night, and possibly into Sunday.

&&

.AVIATION...
VFR conditions are expected at the KEYW and KMTH terminals early
tonight. Winds until then will be from south to southwest at or
below 10 knots. Winds will clock to the southwest and moderate close
to 15 knots early Saturday morning, then strengthen from the
northwest to north close to 20 knots with higher gusts by early
Saturday afternoon. The probability of MVFR or IFR conditions
increases late tonight into Saturday thanks to higher shower
coverage, with a chance of thunderstorms.

&&

.CLIMATE...
In 2010, the high temperature in Key West only hit 61 degrees.
This set the cold high temperature record for December eighth in
the city. Temperature records for Key West date back to 1872.
