.DISCUSSION...
Issued at 1031 PM EDT Fri Mar 15 2024

Higher humidity is definitely more noticeable this evening, with
dew points generally in the lower 70s across the island chain.
Winds have decreased over the past few hours, with winds of 7 to
13 knots being recorded along the Reef. Surface analysis 
highlights the ridge that has been dominating our sensible weather
is retreating further out into the North Atlantic as a cold front
lumbers across the Southeast. Subtle height falls were sampled at
all significant levels across the region as this high looses its 
grip. Temperatures along the island chain have remained steadily 
in the upper 70s, which is a few degrees above normal for this 
time of year. KBYX is echo free and the most cloud cover is upper-
level cirrus moving in from the west. For tonight, temperatures 
will remain in the mid to upper 70s, and dew points will stay 
steady near 70 degrees, so a muggier mid-March night is on tap for
the Florida Keys. Once again, the stable atmospheric environment 
will nix any shower development, so near nil rain chances remain 
in the forecast. Aside from lowering winds in the coastal waters, 
no changes were necessary to the current forecast.

.MARINE...
Issued at 1031 PM EDT Fri Mar 15 2024

There are no watches, warnings, or advisories in effect for the
Florida Keys coastal waters. From synopsis, high pressure across 
Florida will retreat eastward into the Atlantic resulting in 
diminished breezes over the next few days. A cold front is 
expected to push through Keys waters early next week. Breezes will
freshen from the north Monday night and Tuesday morning in the 
wake of the frontal passage.

Issued at 1031 PM EDT Fri Mar 15 2024

range between 7 to 11 knots.
