.SYNOPSIS FOR MID ATLC WATERS...Complex inland low pressure over
the Carolinas will drift NE tonight into Wed, before turning N
and accelerating along the coast of southern New England later
Wed into Wed night. The low will pull a series of fronts across
the region tonight through Wed night. The low will clear well N
of the waters by Thu. A low pressure trough will move E across
the region Wed night and Thu. Another low pressure area will
approach the SE coast Thu night, lift N along the coast Fri and
Fri night, then clear well N of the area Sat. The low will pull a
slow-moving cold front through the region Fri into Sat. The front
will clear E of the waters Sat night, as high pressure builds
behind the front Sat night through Sun night.
