Synopsis
A robust high pressure system over the southeastern United States will spread eastward over the next few days. As a result, light to gentle northeasterly breezes will gradually shift further northeasterly and freshen early this week. As the high slides further southeastward into the west-central North Atlantic, breezes will clock around to the east and modestly slacken by mid week. A strong cold front is expected push through the Keys marine zones late Thursday night, with breezes backing to the northwest and freshening in its wake.
