.SYNOPSIS FOR CALIFORNIA WATERS...High pressure will build E into
the central and southern waters today into Thu. A cold front will
move SE over the northern and central waters Thu and Thu night
weakening the ridge. The front will continue to press SE over the
southern area Fri. High pressure will rebuild E into the central
waters Thu night and Fri behind the cold front. The ridge will
persist across the central region Sat and Sat night, then slowly
shift N Sun and Sun night. A weak low pressure trough will
continue along the southern California coast today into Thu
before weakening late Thu as a cold front approaches. The trough
will reform along the S and central California coast FRi, then
gradually expand N along the coast Fri night into Sun night.
