.DISCUSSION...
Issued at 955 PM EST Wed Nov 19 2025
KBYX has remained echo-free making for a pleasant dry evening.
The 00z sounding tonight measured a decent decrease in
precipitable water from this morning (1.58 inches) to now (0.97
inches) and GOES-19 verifies those conditions with barely any
clouds in the CWA. Temperatures across the island chain are in
the mid to lower 70s with dewpoints in the upper 60s. Along the
Reef, observations are northeasterly winds at 10 to 15 knots. For
the remainder of tonight into the early morning hours, not much
is expected to change from current conditions, as a high sits
across the region resulting in dry and gentle to moderate
northeasterly winds.

.MARINE...
Issued at 955 PM EST Wed Nov 19 2025
No watches, warnings, or advisories are currently in effect for
the Florida Keys waters. From synopsis, a high pressure system
stretching from the western Atlantic to the Florida panhandle will
sustain northeast to east breezes across the Florida Keys coastal
waters. The high will gradually weaken during the second half of
the week, which will allow gentle to moderate breezes to briefly
slacken to light to gentle by the weekend. Expect slightly fresher
breezes south of the island chain. Breezes will gradually freshen
early next week as the pressure gradient slowly tightens due to
an approaching surface low.

.AVIATION...
(00Z TAFS)
Issued at 955 PM EST Wed Nov 19 2025
VFR conditions will prevail at both EYW and MTH through the TAF
period. Dry air will limit any shower development therefore no
mention of VCSH at either terminal. Near surface winds will
continue to be northeasterly at 5 to 10 knots.
