.SYNOPSIS FOR NEW ENGLAND WATERS...High pressure across the
waters will shift E tonight as weak low pressure develops and
moves NE along the Maine coast, pulling a weak warm front NE
across the area. Another warm front will lift N across the waters
Wed ahead of a stronger area of low pressure moving E into
northern New England Wed night. A strong cold front associated
with this system will sweep E and SE over the area Wed night into
Thu, followed by a secondary cold front or low pressure trough
Thu into Fri. High pressure to the S will build E and extend a
ridge across the waters Fri into Sat. Another trough or weak cold
front will cross the area Sat as the ridge shifts E and weakens.
Sat night, developing low pressure with a warm front extending E
from the low will move into the area from the SW. A cold front
will approach the coast from the W late Sat night. The low and
associated front will cross the waters Sun. The cold front will
largely stay S and SE of the area through Sun night as the low
moves NE. High pressure will build across the waters Sun night
behind the cold front.
