.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.
