DISCUSSION
ISSUED AT 1022 PM EDT FRI JUN 26 2026
HEAT CONTINUES TO BE THE PRIMARY CONCERN ACROSS THE FLORIDA KEYS.
TEMPERATURES PEAKED NEAR 90 F ACROSS THE ISLAND CHAIN, THOUGH A
THUNDERSTORM THAT MOVED ACROSS THE FLORIDA KEYS MARATHON
INTERNATIONAL AIRPORT THIS AFTERNOON KEPT THE HIGH IN THE UPPER
80S. DEW POINTS LINGER IN THE MID TO UPPER 70S, WHICH IS WHY HEAT
INDICES HAVE BEEN STRUGGLING TO REACH 108 F. SHOWERS, WHILE NOT
WIDESPREAD, HAVE BEEN RAPIDLY DEVELOPING INTO SHORT LIVED
THUNDERSTORMS ACROSS THE WATERS. THE EVENING KKEY SOUNDING
TRAVELED THROUGH AN ATMOSPHERE WITH AN ENVIRONMENTAL PWAT SLIGHTLY
ABOVE THE 50TH PERCENTILE VALUE. THAT DOES NOT MEAN THE
ENVIRONMENT IS DRY, BECAUSE GOES-EAST ESTIMATED TOTAL PWAT ACROSS
THE KEYS IS 1.7 TO 1.9 INCHES. TURNS OUT THAT SHOWERS AND
THUNDERSTORMS STARTED TO PULSE OVER THE OUTER GULF WATERS SHORTLY
AFTER SUNSET. THE OVERALL SYNOPTIC SETUP IS NOT CHANGING QUICKLY
OVER SOUTH FLORIDA, SO IT'S LIKELY THE OVERNIGHT HOURS WILL BE
DEFINED BY WAXING AND WANING THUNDERSTORMS ACROSS THE NEARSHORE
WATERS. THUS, MAINTAINING THE CURRENT FORECAST FOR THE NIGHT.
MARINE
ISSUED AT 1022 PM EDT FRI JUN 26 2026
NO WATCHES, WARNINGS, OR ADVISORIES ARE IN EFFECT FOR THE FLORIDA
KEYS COASTAL WATERS. FROM SYNOPSIS, A BROAD HIGH PRESSURE SYSTEM
CENTERED OVER THE NORTH ATLANTIC WILL CONTINUE TO EXTEND WESTWARD
TO THE FLORIDA PENINSULA THROUGH EARLY NEXT WEEK. THE HIGH WILL
FLUCTUATE IN STRENGTH AND LOCATION, WHILE MAINTAINING EAST TO
SOUTHEAST BREEZES. THIS WILL SUPPORT BOUTS OF LIGHT TO GENTLE
BREEZES THAT MAY FRESHEN TO GENTLE TO MODERATE AT TIMES, MAINLY IN
THE OVERNIGHT HOURS. IN ADDITION, SCATTERED SHOWERS AND ISOLATED
STORMS WILL MOVE ACROSS ALL COASTAL WATERS OF THE FLORIDA KEYS AT
TIMES, WHICH COULD PRODUCE BLINDING DOWNPOURS, GUSTY WINDS, AND
OCCASIONAL LIGHTNING STRIKES.
AVIATION
(00Z TAFS)
ISSUED AT 1022 PM EDT FRI JUN 26 2026
VFR CONDITIONS WILL PREVAIL AT EYW AND MTH FOR THE UPCOMING
PERIOD. SCATTERED SHRA AND ISOLATED TSRA WILL WAX AND WANE OVER
THE FLORIDA KEYS AIRSPACE. SHORT LIVED MVFR TO IFR CONDITIONS ARE
POSSIBLE IF A TS MOVES OVER ONE OF THE TERMINALS. WINDS WILL
REMAIN NEAR 10 KNOTS OUT OF THE EAST TO SOUTHEAST.
