.SYNOPSIS FOR CALIFORNIA WATERS...A weakening cold front will
begin to dissipate across the central and southern waters today
as it drifts S-SE. Behind the front, a trough will develop along
the N and Central California coast today and persist through Thu
night, while strong high pressure builds in from the W. A weak
area of low pressure will develop near the central California
coast Fri and slide slowly SW through Sat, then diminish into a
trough by late Sat while moving W of the regional waters. Another
cold front will move into the N waters Sun into Sun night. A
trough will reform late Sat night along the N and Central
California coast, as ridging becomes established over the
northern waters, then persists through Mon night.
