.SYNOPSIS...Light, predominantly northeasterly breezes will
linger through the remainder of the weekend. A new continental
high will push in to the eastern United States early next week,
resulting in freshening northeast to easterly breezes. This high
will progress eastward into the Atlantic, and after mid week,
breezes should collapse as the pressure field becomes nebulous.
