.SYNOPSIS FOR NEW ENGLAND WATERS...A weak stationary front near
the coast will persist tonight as a low pressure system
approaches from the S. The low will move NE across the waters Sat
into Sat night. High pressure will build over the region Sun,
then shift E of the area Sun night as weak low pressure passes S
and then SE of the waters. A warm front will lift N toward the
area Sun night as another low develops just S or SW of the
waters. The warm front and low pressure area will lift N and NE
over the area Mon into Mon night. Another low will then track NE
and remain inland over New England Tue with the warm front
lifting N over the area and a trailing cold front approaching
from the W. The low and warm front will pass N of the area Tue
night, with the cold front moving E over the waters. The front
will stall S of the waters Wed into Wed night. Another cold front
will approach from the W and NW by late Wed night.
