.SYNOPSIS FOR CALIFORNIA WATERS...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.
