.SYNOPSIS...A low pressure trough will gradually shift offshore

from the central and southern coast today into Sat, and then

dissipate Sat night into Sun. High pressure will remain just W of

the N waters today into tonight, then weaken Sat and Sat night as

the first in a series of cold fronts moves across the N and

central portions of the waters. The first cold front will weaken

on Sun into Sun night as high pressure rebuilds briefly across

the area, but another cold front will move into the N portions of

the region again during Mon into Mon night, before dissipating

across the central waters on Tue. Yet another cold front will

move into the N waters Tue and Tue night.
