.KEY MESSAGES...

-A significant cold front will continue to blast through the
 Florida Keys today. This will result in much cooler temperatures
 along with windy conditions developing for the first part of the
 work week.

-Temperatures expected to return to slightly below normal by the
 end of the week as a high pressure system sets up over the
 northern Gulf.

.AVIATION...
(18Z TAFS)
Issued at 1247 PM EST Mon Nov 10 2025
Northerly breezes will gust to near 30 knots this evening and
overnight, posing an aviation challenge through 12z Tuesday
morning. BKN CIGs will occasionally drop to around 015, especially
through 06z. Clearing skies along with modestly slackening breezes
are expected thereafter, although confidence in timing for the
clearing is low at this time.

.FORECAST...
Issued at 500 AM EST Mon Nov 10 2025
The big weather story for the Keys today is the passage of the
previously mentioned cold front. Our light to gentle breezes this
morning will rapidly accelerate out of the northwest as this
potent front crosses into and through our waters. Strong breezes
are expected to reach the island chain in the late morning to
early afternoon hours before sweeping into the Straits of Florida
by tonight. As winds increase with the leading edge of the front,
a brief window of chance PoPs will exist this morning with speed
convergence promoting low level lift in what will still be a
somewhat moist environment ahead of the front. Last night`s KKEY
sounding does note dry air already above 650 mb meaning that
thunderstorm chances will still lean near nil.

Strong to near gale force breezes will howl through our waters
tonight. These northerly winds will bring in a dry and cooler air
mass to our CWA with dew points plunging into the 40s and low
temperatures extending below 60 degrees. This will also zero out
rain chances as we get this early taste of dry season conditions.
Winds will start to slacken on Tuesday gradually pulling back to
moderate northeast breezes as a surface high takes control of our
sensible weather by the second half of the week. By then,
temperatures will also have returned to more normal values and
seasonal conditions will continue on through the weekend.

.MARINE...
Issued at 1100 AM EST Mon Nov 10 2025
A Small Craft Advisory is in effect for all Florida Keys marine
zones, with near-gale gusts possible this evening and overnight.
From synopsis, potent cold front will continue push through the
Florida Keys marine zones this afternoon, bringing fresh to strong
northerly breezes in its wake, peaking overnight. As the next
high builds in behind the front, winds will shift out of the
northeast and gradually slacken. Moderate to occasionally fresh
breezes will remain possible through the end of the work week.
