DISCUSSION

Issued at 1115 PM EDT Sat Jun 13 2026 A mostly uneventful night has unfolded for the Florida Keys. A few light showers have popped up in various marine zones but nothing of worthy mention. Temperatures across the island chain are in the lower 80s and dewpoints are in the mid 70s making for another muggy night. Nighttime Microphysics reveals a few wispy clouds out there but most locations are clear skies. Though not much is happening with it besides it being muggy, the 00z KKEY sounding tonight did measure 2.14 inches which is above the 90 percentile for the day according to SPC climatology. Across the Reef marine locations are observing light winds of 5 to 10 knots. Not much is expected to change over the rest of tonight therefore no changes were made to the update package!

MARINE

Issued at 1115 PM EDT Sat Jun 13 2026 No watches, warnings, or advisories are currently in effect for the Florida Keys waters. From synopsis, light to gentle east to southeasterly breezes will persist across the Florida Keys. The combination of a well- developed mid-latitude trough over the eastern United States and a weak disturbance over the Bay of Campeche weakened the ridge over the Caribbean Sea. Breezes are on track to veer southeast to south late in the weekend and early next week.

AVIATION

(00Z TAFS) Issued at 1115 PM EDT Sat Jun 13 2026 VFR conditions will prevail at both EYW and MTH through the TAF period. A this time shower activity is expected to be limited therefore VCSH has been removed from both terminals. Near surface winds will be southeasterly at 5 to 10 knots.
