.SYNOPSIS FOR NEW ENGLAND WATERS...A warm front extending from
Cape Cod eastward will lift N of the waters early tonight. A
strong low pressure system will move from New York state to the
Canadian Maritimes tonight into Wed, while pulling a strong cold
front through the region. As the strong low moves farther north
into Canada Wed night, a weaker low pressure system will move
across the northern mid-Atlantic waters Thu, followed by another
low pressure system Fri into Fri night. The low will intensify to
the E of the waters Sat as high pressure builds E from the Great
Lakes. The high will cross the waters from W to E late Sat night
into Sun, then move E and SE of the region Sun night as the next
cold front approaches from the W.
