IT HAS BEEN A MOSTLY QUIET EVENING SHIFT AT THE OFFICE OUTSIDE OF
THE ISOLATED SHOWERS AND THUNDERSTORMS THAT OCCURRED OVER THE
LOCAL WATERS EARLIER TODAY. WE DON’T HAVE A LOT OF AUTOMATED
OBSERVATIONS ALONG THE ISLAND CHAIN, BUT THE AWOS IN KEY LARGO DID
REPORT ONE HUNDREDTH OF AN INCH AROUND 2 PM EDT. AT THE TIME WE
ARE WRITING THIS, APPROXIMATELY 10 PM EDT, OUR KBYX RADAR IS ONLY
DETECTING A COUPLE OF WEAK, ISOLATED SHOWERS IN EASTERN PORTIONS
OF THE DISTANT FLORIDA STRAITS. OUR RADAR CAN ALSO SEE THAT MOST
OF THE CONVECTION FROM THIS EVENING OVER THE PENINSULA HAS MOSTLY
FIZZLED OUT, BUT WHATEVER IS STILL LEFT ON THE RADAR WHEN WE POST
THIS ISN’T GOING TO BOTHER US TONIGHT. GOES-19 CLOUD TOP SHOWS A
MIX OF SOME LOW LEVEL AND HIGH LEVEL CLOUDS ACROSS THE SKIES, BUT
NOTHING WIDESPREAD ENOUGH TO BLOCK OUR VIEW OF THE STARS.
IT WAS ANOTHER TOASTY DAY AS OUR PRELIMINARY EVENING CLIMATE DATA
SHOWED A HIGH TEMPERATURE OF 89F AT KEY WEST INTERNATIONAL
AIRPORT, AND 88F AT MARATHON AIRPORT. HEALTHY DEW POINTS IN THE
UPPER 70S GAVE US HEAT INDICES IN THE UPPER 90S TO LOW 100S AT
TIMES, AND THIS IS ESSENTIALLY GOING TO BE THE NAME OF THE GAME
FROM HERE ON OUT AS “FLORIDA SUMMER” SETTLES IN FOR THE SEASON.
LOOKING AT CURRENT OBSERVATIONS, WE SEE TEMPERATURES THAT ARE IN
THE UPPER 80S, SO WE CAN’T IN GOOD FAITH TELL YOU THAT IT IS
COOLING DOWN NOW THAT THE SUN HAS SET.
THE INHERITED FORECAST ADVERTISES A SLIGHT CHANCES OF SHOWERS AND
THUNDERSTORMS OVERNIGHT. WHILE THERE ISN’T ANY APPARENT LARGE
SCALE LIFT TO GET ANYTHING GOING, THE ENVIRONMENT DOESN’T ENTIRELY
RULE OUT ANY ACTIVITY. BETWEEN LINGERING GHOST BOUNDARIES FROM
EARLIER CONVECTION, AND SPEED CONVERGENCE FROM FRESHENING BREEZES
OVERNIGHT, IT IS POSSIBLE WE COULD SEE A COUPLE OF STRAY SHOWERS
AND THUNDERSTORMS. FOR THAT REASON, WE WILL GO AHEAD AND CONTINUE
WITH THE CURRENT FORECAST PACKAGE. NO CHANGES OR UPDATES WILL BE
MADE AT THIS TIME.
MARINE
ISSUED AT 1007 PM EDT SUN MAY 25 2025
THERE ARE NO WATCHES, WARNINGS, OR ADVISORIES IN EFFECT ACROSS THE
FLORIDA KEYS LOCAL WATERS. FROM SYNOPSIS, HIGH PRESSURE WILL
REMAIN ENTRENCHED OVER THE WESTERN NORTH ATLANTIC FOR THE NEXT
SEVERAL DAYS, MEANDERING AND FLUCTUATING IN STRENGTH SLIGHTLY DAY
TO DAY. THIS WILL LEAD TO MAINLY GENTLE TO MODERATE EAST TO
SOUTHEAST BREEZES, OCCASIONALLY BECOMING SOUTHEASTERLY. IN THE
STRAITS OF FLORIDA, BREEZES MAY OCCASIONALLY BECOME MODERATE TO
FRESH. BREEZES WILL PEAK LATE EVENING INTO THE MORNING HOURS AND
LULL IN THE AFTERNOON AND EARLY EVENINGS.
AVIATION
(00Z TAFS)
ISSUED AT 1007 PM EDT SUN MAY 25 2025
VFR CONDITIONS AND DRY WEATHER WILL CONTINUE AT BOTH ISLAND
TERMINALS OVERNIGHT AND THROUGH MONDAY. THERE IS A SLIGHT CHANCE
FOR SHOWERS OR THUNDERSTORMS, BUT THE PROBABILITY IS TOO LOW TO
CONFIDENTLY PUT ANY VCSH OR VCTS IN THE CURRENT TAFS. SOUTHEAST
BREEZES NEAR 10 KNOTS WILL CONTINUE TO PREVAIL.
