DISCUSSION

THE AFTERNOON STARTED WITH A HEALTHY REVERSE CLOUD LINE THAT
EXTENDED FROM BIG PINE KEY TO THE FLORIDA BAY. ONCE THE SUN SET,
THIS LINE QUICKLY FELL APART AND DISSIPATE. SINCE THEN, THE KBYX
RADAR HAS BEEN PRECIPITATION-FREE THIS EVENING. MEANWHILE, THE
WESTERN PERIPHERY OF AN ATLANTIC RIDGE CONTINUES TO NOSE IN FROM
THE EAST. THIS WESTERN EXTENT THOUGH IS FAIRLY STRETCHED OUT AND
LOOKS TO SPLINTER INTO A SMALLER WEAKER HIGH SITUATED ACROSS THE
GULF BASIN OVER THE NET 24 HOURS. THIS WILL DO ONE OF TWO THINGS.
THE FIRST, IT WILL LEAD TO A WEAKENING PRESSURE FIELD AND BECOMING
MORE NEBULOUS. THIS WILL RESULT IN SLACKENING WINDS OVERNIGHT
THROUGH THURSDAY NIGHT. THE SECOND, WHEN IT DOES COMPLETE ITS
SPLIT, THE KEYS WILL BE LEFT IN A COL REGION BETWEEN FEATURES.
THIS WILL ALLOW WINDS TO FURTHER WEAKEN AND BECOME LIGHT AND
VARIABLE AT TIMES BY FRIDAY. LASTLY, A COMBINATION OF WEAKENING
FLOW AND RELATIVELY DRIER AIR WILL BRING POPS BACK BELOW NORMAL
FOR THE END OF THE WEEK.
MARINE
ISSUED AT 1007 PM EDT WED JUL 29 2026
SOUTHWEST BREEZES HAVE SLACKENED FROM EARLIER IN THE AFTERNOON AND
ARE WE ARE CURRENTLY SEEING GENTLE BREEZES ACROSS MARINE
PLATFORMS. AS THE WESTERN PERIPHERY OF AN ATLANTIC RIDGE CONTINUES
TO NOSE IT, WINDS WILL SLACKEN AS A WEAK AND NEBULOUS PRESSURE
PATTERNS DEVELOPS. A COL REGION WILL SET UP FOR LATE WEEK INTO
THE FIRST PART OF THE WEEKEND, RESULTING IN A POTENTIAL PERIOD OF
LIGHT AND VARIABLE BREEZES. AS HIGH PRESSURE STRENGTHENS IN THE
NORTH ATLANTIC, SOUTHEAST BREEZES WILL FRESHEN BY THE SECOND HALF
OF THE WEEKEND AND INTO EARLY NEXT WEEK.
