.SYNOPSIS FOR NEW ENGLAND WATERS...A cold front will clear E of
the waters today, then stall S of the waters tonight through Fri
night. Weak low pressure will form along the stalled boundary
Thu, then track E along the front Thu night through Fri night
while passing along or just S of the area. High pressure will
build N of the waters behind the front late today into tonight,
then shift NE Thu while maintaining a ridge over the waters Thu
through Fri. The ridge will dissipate late Fri into Fri night,
allowing the stationary front to lift back N across the waters as
a warm front Sat and Sat night. A strong cold front will slowly
approach the coast Sun and Sun night.
