DISCUSSION
ISSUED AT 1030 AM EST TUE NOV 4 2025
A STRONG SURFACE HIGH CENTERED OVER THE SOUTHEASTERN UNITED
STATES IS MAINTAINING MODERATE NORTHEASTERLY BREEZES ACROSS THE
KEYS THIS MORNING. WHILE THIS IS IN WAKE OF A RECENT COLD FRONT
PASSAGE, THE FLOW HAS VEERED TOO FAST TO ALLOW FOR MUCH IN THE WAY
OF COLD AIR ADVECTION. AS A RESULT, TEMPERATURES REMAIN NEAR
SEASONAL NORMS, CURRENTLY IN THE MID 70S, WITH DEW POINTS UNMOVED
AT NEAR 70. WITH THAT SAID, SOME DRIER AND MORE STABLE AIR HAS
PUSHED IN THROUGH THE LOWER LEVELS. THIS MORNINGS SOUNDING
INDICATED A PRECIPITABLE WATER OF 1.59 INCHES, WHICH IS JUST A
TOUCH HIGHER THAN NORMAL. THE ISLAND CHAIN HAS BEEN PRECIPITATION
FREE THROUGH THE MORNING, AND ALL SHOWERS ARE RELEGATED TO THE
DISTANT SOUTHWESTERN FLORIDA STRAITS.
LITTLE CHANGE IS EXPECTED IN THE OVER ALL SETUP THROUGH THE
AFTERNOON. MAINLAND DAY TIME HEATING SHOULD HELP CUT DOWN THE WIND
FIELD IN THE LEE, BUT THIS REDUCTION IS EXPECTED TO REMAIN TO OUR
NORTH ACROSS OUR GULF WATERS. AS A RESULT, EXPECT WINDS TO REMAIN
GENTLE TO MODERATE AND BROADLY NORTHEASTERLY. RAIN CHANCES WILL
REMAIN NIL. CLOUD COVER WILL REMAIN CONSIDERABLE THANKS TO A BROAD
MID DECK SHIELD EMANATING OUT OF THE WESTERN CARIBBEAN SEA. EXPECT
SEASONAL HIGHS NEAR 80 WITH DEW POINTS LINGERING NEAR 70.
MARINE
ISSUED AT 1030 AM EST TUE NOV 4 2025

WATERS THIS AFTERNOON. A SMALL CRAFT ADVISORY REMAINS IN EFFECT
FOR HAWK CHANNEL AND FLORIDA STRAITS.
