.SYNOPSIS FOR NEW ENGLAND WATERS...Broad complex low pressure
will slowly move E across the Gulf of Saint Lawrence and
Newfoundland through Sun, with a series of associated weak
surface troughs moving across the waters through Sun. Broad high
pressure S of the area will briefly extend across the southern
portions Sun night and early Mon. Low pressure inland will drive
a warm front offshore from the Mid-Atlantic and N across the
waters Mon into early Tue. The associated cold front will push E
across the waters Tue, then clear SE of the waters Tue night.
Behind the front high pressure will build offshore Wed, then
gradually slide E across the area through Wed night. A weak area
of low pressure will move off the Mid-Atlantic coast and approach
the area from the S Thu and Thu night.
