.SYNOPSIS FOR NEW ENGLAND WATERS...A weak cold front will move SE
across the area early today. A high pressure ridge will build E
over the waters today and persist through tonight, then slowly
shift E of the region by Thu. Low pressure will develop off the
Mid-Atlantic coast Thu, then drift E and SE Thu night into Fri
while remaining S of the waters. Another high will build S over
the N waters late Thu, persist over the region Thu night into
Fri, and then shift E of the waters Fri night. The low will then
move back to the N and dissipate as a cold front approaches from
the W. The cold front will move across the area Sat into Sat
night. A series of low pressure troughs or secondary cold fronts
will move SE across the waters Sun and Sun night.
