.DISCUSSION...
Issued at 1222 PM EST Thu Nov 20 2025

Ridging continues to dominate the synoptic pattern for the
Florida Keys. A series of inversions sprinkle the 12z morning
sounding at KEY. CIMSS tropospheric-integrated precipitable water
product highlights tremendous dry, modified continental air
upstream filtering in steering northeasterlies. A persistence
forecast is in play, with no changes needed to the inherited
overnight full forecast package.

.MARINE...
Issued at 1222 PM EST Thu Nov 20 2025

No watches, warnings, or advisories are in effect for the Florida
Keys coastal waters. From synopsis, a surface high will
consolidate along the Atlantic coast over the next couple of days.
This, along with diurnal influences, should result in slightly
freshening northeast to easterly breezes this evening. Winds will
slacken some through the remainder of the week as this high tilts
eastward and lengthens out into the Atlantic. A new continental
high will build as it drive eastward through the eastern United
States early next week. This is expected to freshen easterly
breezes.

.AVIATION...
(18Z TAFS)
Issued at 1222 PM EST Thu Nov 20 2025

VFR conditions will prevail throughout the forecast period. East
to northeasterly winds will remain in place through Friday
morning and will generally range between 5 to 10 kts.

.KEY WATCHES/WARNINGS/ADVISORIES...
FL...None.
