.DISCUSSION...
Issued at 1053 AM EDT Sat Jun 28 2025
The moisture profile sampled in the 12z morning sounding at KEY
is a fantastic display of a Saharan Air Layer (SAL), with
tremendous amounts of dry air between 800-500 mb. Coupled with a
unidirectional 0-3 km low-level winds and only gentle east to
southeast flow, it is no surprise that KBYX is void of any
meteorological echo returns. Temperatures are quickly rising, well
into the upper 80s, with feels-like temperatures into the low
100s. For the balance of today, a routine forecast, with SAL
dominating the mainly dry and warm forecast. No changes proposed
to the inherited 10% chances for rain and thunder (which may be a
bit generous).

.MARINE...
Issued at 1053 AM EDT Sat Jun 28 2025
No watches, warnings, or advisories are currently in effect for
the coastal waters of the Florida Keys. From synopsis, broad
surface ridging will continue to rebuild over the Atlantic and
support gentle to moderate east to southeasterly breezes across
Florida Keys coastal waters. A Saharan Air Layer will limit shower
coverage over the weekend, but bursts of showers or thunderstorms
cannot be ruled out. A return to near-normal rain and thunder
chances is expected for early next week.

.AVIATION...
(15Z TAFS)
Issued at 1053 AM EDT Sat Jun 28 2025
VFR conditions will prevail at both island terminals with near-nil
rain chances. Near-surface winds will remain out of the east to
southeast at near 10 knots.
