.SYNOPSIS...Strong high pressure moving across the Great Lakes
region will pivot towards the Northeast U.S. coast into tonight.

through Sunday. Thereafter, a weak easterly wave will push across
the area late this weekend into early next week, and will slacken
breezes. A cold front is progged to approach the Keys later next
week with another surge of easterly breezes expected.
