.SYNOPSIS FOR NEW ENGLAND WATERS...A cold front moving SE across
the waters tonight will clear E and SE of the area by Fri. High 
pressure will build to the SW of the area Fri, as a low pressure 
trough or weak cold front approaches the coast. The trough or
weak cold front will move E and SE over the area Fri night as 
the high builds NE into New England. The high will build E over 
most of the area Sat into Sat night, before shifting E of the 
waters Sun. A warm front will approach the waters from the S Sun,
then lift N into the S waters Sun night as another cold front 
approaches the coast and low pressure organizes S of Long 
Island. The low will move E and NE and cross the far S waters 
Mon while pulling the associated cold front E over the waters. 
Both the low and cold front will clear E of the waters Mon night.
A weak high pressure ridge will cross the area early Tue, 
followed by the next cold front approaching the coast late Tue. 
The cold front will cross the waters Tue night as low pressure 
strengthens just N of the area.
