VFR CONDITIONS WILL PREVAIL UNDER GENTLE TO MODERATE SOUTHEAST
BREEZES. DRIER AIR IS MIXING DOWN AND HELPING TO ERODE THIS
MORNING'S CLOUD COVER. EXPECT OCCASIONAL CU TO RE-DEVELOP AND MOVE
ACROSS THE TERMINALS IN THE EVENING AND OVERNIGHT. OTHERWISE, NO
IMPACTS EXPECTED.

A MUGGY MORNING ACROSS THE FLORIDA KEYS. TEMPERATURES AS OF 10 AM
ARE IN THE MID TO UPPER 80S WITH DEW POINTS HOVERING IN THE MID
70S. THE COMBINATION OF WHICH IS ALREADY PRODUCING HEAT INDICES
BETWEEN 95 AND 100 DEGREES. THANKFULLY WE DO HAVE A DECENT WIND
FROM THE SOUTHEAST AT GENERALLY 10 TO 15 MPH. THIS HOWEVER, ONLY
PROVIDES A SLIGHT EDGE OFF THE REAL FEEL TEMPERATURE. WE CONTINUE
TO SUGGEST THAT YOU SEEK SHADE WHILE TAKING BREAKS, HAVE PLENTY OF
WATER ON HAND, AND WEAR LIGHT CLOTHING TODAY.
DEEP LAYER RIDGING HAS RE-ESTABLISHED ITSELF ACROSS THE REGION,
WHICH IS HELPING TO KEEP A LID ON MOST ACTIVITY, ESPECIALLY ACROSS
OUR IMMEDIATE AREA. KBYX AND KAMX RADARS SHOW LINES OF SHOWERS AND
ISOLATED THUNDERSTORMS PIVOTING AROUND THE SOUTHWESTERN PERIPHERY
OF A SURFACE HIGH OUT ACROSS THE ATLANTIC. THE MOVEMENT OF THIS
ACTIVITY HAS BEEN TO GO INTO BISCAYNE BAY AND POINTS ACROSS SOUTH
FLORIDA. RELATIVELY DRIER AIR, ALONG WITH SUBSIDENCE ACROSS THE
KEYS IS KEEPING RAIN AT BAY AND WILL DO SO FOR THE REMAINDER OF
THE DAY. THERE ARE NO CHANGES PLANNED OR NEEDED AT THIS TIME.

ISSUED AT 1015 AM EDT TUE MAY 27 2025
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. LOOKING AHEAD, GUIDANCE SUGGESTS A SHIFT IN THE PATTERN
THAT MAY LEAD TO AN INCREASE IN THE POTENTIAL FOR SHOWERS AND
THUNDERSTORMS NEAR THE END OF THE WEEK, BUT DETAILS WILL CONTINUE
TO BE SPARSE UNTIL WE GET CLOSER TO THAT TIME.
