IT HAS BEEN AN ABSOLUTE BEAUT OF A DAY. PLENTY OF SUNSHINE, MILD
TEMPERATURES, AND COMFORTABLE DEW POINTS. TEMPERATURE HAVE MADE IT INTO
THE MID TO UPPER 70S AND HAVE LIKELY PEAKED GIVEN THE NORTHERLY
FLOW. WINDS QUICKLY CAME DOWN AFTER SUNRISE AND HAVE REMAINED
LIGHT AROUND 10 MPH OR LESS. A BOUNDARY NOTED THIS MORNING HAS
FINALLY PUSHED ENOUGH WESTWARD TO BEGIN MOVING THROUGH PORTIONS OF
THE UPPER KEYS. BEHIND THIS BOUNDARY WINDS HAVE GONE EAST WITH
SOME ISOLATED CLOUDS.THIS BOUNDARY WILL ACCELERATE ACROSS THE AREA
TONIGHT, LEADING TO A WIDESPREAD SURGE IN EASTERLY WINDS.
FORECAST
THE FLORIDA KEYS ARE SET TO ENJOY A VERY PLEASANT WEEK, ALL THINGS
CONSIDERED. THE EXPANSIVE SURFACE HIGH PRESSURE ACROSS THE EASTERN
THIRD OF THE U.S. WILL SETTLE SOUTHEAST AND EXTEND FROM JUST EAST
OF THE BAHAMAS, ACROSS THE SUNSHINE STATE AND OVER TO THE GULF.
THIS IN CONJUNCTION WITH LOW LEVEL RIDGING, WILL KEEP RAIN CHANCES
AT BAY. IN ADDITION, THE PLACEMENT OF THE SURFACE FEATURE WILL
ALLOW FOR WINDS TO CLOCK AROUND TO THE EAST STARTING LATE THIS
EVENING AND CONTINUING INTO THE NEW WORK WEEK. HOWEVER, EVEN
THOUGH WE WILL BE GOING EASTERLY, DRY AIR ALOFT WILL MIX DOWN AND
KEEP DEW POINTS BELOW 70 DEGREES.
A POTENT SURFACE LOW TREKKING THROUGH THE GREAT LAKES WILL FLATTEN
OUR SURFACE HIGH ON TUESDAY, LEADING TO A BRIEF PERIOD OF
POTENTIALLY LIGHT AND VARIABLE WINDS. IN ADDITION, A WEAK BACK
DOOR "FRONT" WILL PUSH THROUGH THE KEYS LATE TUESDAY, ALLOWING FOR
WINDS TO BACK TOWARDS THE NORTHWEST BRIEFLY ON WEDNESDAY. BY
THURSDAY, THE NEXT SURFACE HIGH WILL QUICKLY FILL IN AND SETTLE
ACROSS THE SOUTHEAST U.S. AS A RESULT WINDS WILL BOX AROUND THE
COMPASS RATHER QUICKLY, SHIFTING TO NORTHEAST AND THEN EAST
THURSDAY NIGHT.
THIS NEXT HIGH WILL THEN SLOWLY TRUDGE EASTWARD OUT ACROSS THE
ATLANTIC AND BUILD. THIS WILL LEAD TO A PROLONGED PERIOD OF FRESH
TO POSSIBLY STRONG BREEZES ACROSS THE REGION. AGAIN, HOWEVER,
THOUGH WE WILL HAVE A GOOD EASTERLY GRADIENT, MOISTURE WILL
CONTINUE TO REMAIN LIMITED. THIS MEAN THAT NOT ONLY WILL RAIN
CHANCES CONTINUE TO BE NEAR NIL, BUT DEW POINTS WILL HOLD BELOW 70
DEGREES. THE COMBINATION OF WIND AND LOWER DEW POINTS WILL MAKE IT
QUITE PLEASANT TO BE OUT AND ABOUT, BUT MAY JUST NOT ON THE WATER
(SORRY).
MARINE
ISSUED AT 300 PM EDT SUN APR 13 2025
HIGH PRESSURE WILL SETTLE ACROSS THE FLORIDA PENINSULA THROUGH
MONDAY NIGHT. THIS WILL RESULT IN A BRIEF EPISODE OF FRESHENING
EASTERLY BREEZES. BREEZES WILL SLACKEN AS A WEAK BACK DOOR FRONT
PASSES THROUGH THE KEYS LATE TUESDAY INTO WEDNESDAY. THEN,
REINFORCING HIGH PRESSURE ARRIVES TOWARDS THURSDAY LEADING TO A
STRONGER ROUND OF FRESHENING BREEZES.
