.SYNOPSIS...Moderate breezes will gradually slacken to light to
gentle over the weekend, while high pressure across the Southeast

further, becoming light and variable Sunday and Sunday night.
High pressure will then lift northward and gradually strengthen,
allowing for a slow freshening of breezes for early next week.
