What forecasters said that day

The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Key West, FL wrote its last area forecast discussion before this small craft advisory went out at Dec 25, 3:07 PM EST, 1 hour 15 minutes earlier.

Area forecast discussion, Dec 25, 3:07 PM EST, 1 hour 15 minutes before
Area Forecast Discussion
National Weather Service Key West FL
307 PM EST Tue Dec 25 2018

.DISCUSSION...
Currently - High pressure centered over the mid Atlantic is
spreading eastward into the Atlantic resulting in moderate to
fresh northeast breezes across the Florida Keys, with the
strongest winds present on our deep gulf and Florida Straits
waters. Stable conditions continue with weakening but still
present subsidence inversion and a 10 degree surface dew point
depression. Stratocumulus is spreading northwestward from cumulus
in the Florida Straits, and has affected mainly the Middle and
Upper Keys.

Forecast - Surface winds will gradually strengthen and veer more
easterly over the next 24 hours as the high continues to build
eastward and the high itself is reinforced by a shortwave ridge
swinging northeastward over the eastern United States. Expect
breezy to windy conditions to set in by morning. The increasingly
easterly flow will result in an increase in surface temps to above
normal and dew points to climb towards 70. Rain chances will
increase through this period due to the increasing flow along with
a swath of ample low level moisture moving into the forecast area.
This will also be aided by developing good isentropic lift.

Breezy to windy conditions will continue into early Friday. The
high will then migrate eastward into the Atlantic leaving a
weakening ridge across Florida and the Keys heading into the
weekend. Winds will slacken out of the southeast fairly quickly
Friday into Saturday. Through the weekend, expect slight chance
pops at best with above normal temps and moisture.

&&

.MARINE...
High pressure centered over the mid Atlantic will strengthen over
the next 24 hours, resulting in freshening northeast to east
breezes across Florida Keys waters tonight into Wednesday. A small
craft advisory will be issued for most Keys waters for these
increasing winds. Northeast to east breezes will remain fresh
while exhibiting a gradual veering trend towards easterly through
Thursday night. Winds will relax quickly Friday into Saturday and
clock further southeast as the high shifts out into the Atlantic
trailing a weakening ridge across Florida and the Keys. Advisories
will be pared back beginning Friday.
