.SYNOPSIS FOR NEW ENGLAND WATERS...A strong cold front moving SE
over the waters early today will clear E and S of the area by
later this morning. High pressure will build E across the waters
later today into Tue. The high will shift E Tue night as weak 
low pressure develops and moves NE along the Maine coast, pulling
a warm front NE across the area. Another warm front will lift N 
across the waters Wed ahead of a stronger area of low pressure 
moving E into northern New England. A strong cold front 
associated with this system will sweep SE across the area Wed 
night into Thu. High pressure will build to the SW of the waters
Thu night, build E and pass S of the waters Fri, then weaken to
the SE of the area Fri night. Yet another cold front will move E
and SE over the waters Fri night as low pressure develops to the
SW and S of the area.
