AVIATION
(18Z TAFS)
ISSUED AT 134 PM EDT TUE JUN 23 2026
CONDITIONS WILL REMAIN DRY ACROSS THE TAFS THROUGH AT LEAST 06Z
THIS EVENING. INCREASING LOW-LEVEL MOISTURE MAY SPARK A FEW
SHOWERS OR ISOLATED THUNDERSTORMS THEREAFTER THROUGH 18Z
WEDNESDAY AFTERNOON. HOWEVER, THE LACK OF COVERAGE AND IMPACTS TO
VISIBILITIES AS WELL AS CEILINGS WARRANTS KEEPING MENTION OUT OF
THE DETERMINISTIC TAFS. NEAR- SURFACE WINDS OUT OF THE SOUTHEAST
WILL SLOWLY BACK TO THE EAST TO SOUTHEAST OVERNIGHT.
PREV DISCUSSION
ISSUED AT 428 AM EDT TUE JUN 23 2026
AS THE SAL EXITS STAGE LEFT TONIGHT, SOMEWHAT BETTER MOISTURE
WILL RETURN. THAT BEING SAID, RAIN CHANCES WILL CONTINUE TO
UNIMPRESSIVE AT 10 PERCENT OR LESS. RAIN CHANCES MAY TICK UP
SLIGHTLY AS A WEAK EASTERLY UNDULATION PIVOTS UP FROM THE
CARIBBEAN FRIDAY NIGHT THROUGH SATURDAY EVENING. ANOTHER EASTERLY
UNDULATION ARRIVES FROM NEAR THE BAHAMAS MONDAY INTO TUESDAY WITH
THE POTENTIAL FOR BETTER MOISTURE AND THEREFORE ACCUMULATING
RAINS.
OTHERWISE, TEMPERATURES WILL REMAIN RATHER STAGNANT WITH DAY TIME
HIGHS NEAR 90 DEGREES AND OVERNIGHT LOWS IN THE LOWER TO MID 80S.
MUGGY CONDITIONS WILL PERSIST WITH DAILY HEAT INDICES REACHING OR
EXCEEDING 105 DEGREES.
MARINE
ISSUED AT 1035 AM EDT TUE JUN 23 2026
ANY RESIDUAL SHOWERS AND THUNDERSTORMS IN THE SOUTHEASTERN GULF
WILL CONTINUE TO DISSIPATE OVER THE NEXT COUPLE OF HOURS. FROM
SYNOPSIS, A BROAD, WEAK HIGH PRESSURE SYSTEM STRETCHING FROM THE
GULF BASIN, ACROSS THE FLORIDA PENINSULA, AND INTO THE CENTRAL
NORTH ATLANTIC WILL FLUCTUATE IN STRENGTH OVER THE NEXT SEVERAL
DAYS. AS A RESULT, EXPECT BOTH WIND SPEEDS AND DIRECTION TO BE
PRIMARILY MESOSCALE DRIVEN AND AT TIMES CHAOTIC. BY WEDNESDAY
NIGHT, THE HIGH WILL BEGIN TO GRADUALLY BUILD AND ALLOW FOR A SLOW
FRESHENING OF EAST TO SOUTHEAST BREEZES.
