DISCUSSION
ISSUED AT 540 AM EDT MON JUN 29 2026
A MOSTLY UNEVENTFUL NIGHT FOR THE FLORIDA KEYS. KBYX HAS REMAINED
SHOWER-FREE FOR THE MAJORITY OF THE NIGHT, ALTHOUGH SOME SHOWERS
ARE POPPING UP ALONG SOME BOUNDARIES IN OUR WATERS OVER THE LAST
HOUR OR SO. THESE SHOWERS HAVE BEEN LIGHT AND SHORT FUSED AND SO
FAR NONE HAVE MADE IT TO THE ISLAND CHAIN. SEEN ON MIMIC PWAT,
DRY AIR HAS MOVED INTO THE AREA WHICH IS HELPING LIMIT THESE
SHOWERS. TEMPERATURES ALONG THE ISLAND CHAIN ARE IN THE MID 80S
WITH DEWPOINTS IN THE MID 70S ONCE AGAIN MAKING FOR MUGGY
CONDITIONS. ALONG THE REEF, WIND OBSERVATIONS ARE EASTERLY AT 10
TO 15 KNOTS. TODAY WILL BE SIMILAR TO PREVIOUS WITH CHANCES OF
SHOWERS AND THUNDERSTORMS BUT NOTHING THAT WILL LAST LONG DUE TO
DRY AIR IN THE AREA. A FRONTAL BOUNDARY IS EXPECTED TO MOVE DOWN
FLORIDA LATER TONIGHT BUT NOT MUCH IS EXPECTED FOR US TO CHANGE.
AS THE FRONTAL BOUNDARY WEAKENS THE HIGH THAT HAS BEEN CONTROLLING
OUR WINDS, THEY WILL START TO SLACKEN. TEMPERATURES AND DEWPOINTS
WILL REMAIN SIMILAR TO THE FOLLOWING DAYS SO MUGGY AND WARM
CONDITIONS WILL CONTINUE.
MARINE
ISSUED AT 540 AM EDT MON JUN 29 2026
NO WATCHES, WARNINGS, OR ADVISORIES ARE CURRENTLY IN EFFECT FOR
THE FLORIDA KEYS WATERS. FROM SYNOPSIS, A BROAD HIGH PRESSURE
SYSTEM CENTERED OVER THE NORTH ATLANTIC WILL CONTINUE TO EXTEND
WESTWARD TO THE FLORIDA PENINSULA THROUGH TODAY. THIS WILL SUPPORT
BOUTS OF LIGHT TO GENTLE BREEZES THAT MAY FRESHEN TO GENTLE TO
MODERATE AT TIMES. STARTING LATE TONIGHT, A FRONTAL BOUNDARY WILL
PRESS SOUTH ACROSS THE FLORIDA PENINSULA AND STALL ACROSS CENTRAL
FLORIDA. THIS WILL ACT TO WEAKEN THE HIGH AND ALLOW FOR SLACKENING
BREEZES THROUGH THURSDAY. THEREAFTER, BREEZES WILL RESUME A CYCLE
OF OVERNIGHT PEAKS AND DAYTIME LULLS.

THROUGH THE AFTERNOON.
