AS HIGH PRESSURE DOMINATES THE WEATHER PATTERN OVER OUR LOCAL
WATERS. THE EXCEPTION WILL BE ACROSS THE COOLER, SHALLOWER WATERS
NORTH OF THE ISLAND CHAIN, WHERE BREEZES WILL BE LIGHT TO GENTLE.
MEANWHILE, A BROAD SURFACE HIGH PRESSURE EXTENDS ALONG THE
ENTIRETY OF THE EASTERN SEABOARD AND IS IN THE PROCESS OF BECOMING
DISORGANIZED. A NEW SURFACE HIGH WILL CONSOLIDATE OFF THE
SOUTHEASTERN U.S. COAST TUESDAY AND SLOWLY MEANDER EAST OUT ACROSS
THE ATLANTIC. THIS WILL MAINTAIN A WAX AND WANING OF BREEZES
TODAY THROUGH AT LEAST WEDNESDAY. TOWARDS THE END OF THE WEEK, THE
HIGH WILL FLATTEN AND EXPAND WESTWARD ACROSS THE FLORIDA KEYS,
LEADING TO A BRIEF PERIOD OF LIGHT AND VARIABLE BREEZES.
