.SYNOPSIS FOR NEW ENGLAND WATERS...Weak high pressure will 
remain over the area through Thu as weak lows move NE along a 
surface front nearly stationary just SE of the waters. High 
pressure gradually shifts E Thu night and Fri ahead of a cold 
front. This slow-moving front approaches the coast Fri, and 
weakens as it moves E across the waters Fri and Fri night. 
Another cold front approaches from the W Sat, moves into the 
area Sat night, and finally passes through the area by late Sun 
night. High pressure builds in from the W behind the front.
