.SYNOPSIS FOR MID ATLC WATERS...Low pressure south of
Newfoundland will continue to move northeast overnight. Behind
the low, a cold front will slowly move southeast across the
waters through tonight. Another low moves off of the Carolina
coast Friday, and then will move northeast toward Newfoundland
Friday night and Saturday while strengthening. As the low moves
well to the northeast of the waters, high pressure builds in from
the west from Saturday afternoon through Sunday night. High
pressure remains over the far southern waters Monday and Monday
night, while a weak low pressure and frontal boundary moves east
across the central and northern zones. A cold front approaches
from the northwest Tuesday, then moves across the waters Tuesday
night.
