.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.
