.SYNOPSIS FOR NEW ENGLAND WATERS...Deep low pressure near the
island of Newfoundland will continue to move NE away from the 
waters today. A high pressure ridge will slowly drift E over the
region today, then move E of the area by Thu night. Strengthening
low pressure will track N and NE from the SE U.S. and approach 
the waters Thu night, pass W of the area while lifting a warm 
front over the waters Fri into Fri night, then pass N of the 
region late Fri night into Sat with an associated cold front 
crossing the waters. A secondary cold front or low pressure 
trough will pass SE over the area Sat night into early Sun. A 
weak high pressure ridge will then approach from the W late Sun, 
then cross the waters Sun night ahead of a weak low pressure 
system moving E from the Great Lakes.
