.SYNOPSIS FOR CALIFORNIA WATERS...A trough along the California
Coast will persist today. A high pressure ridge will build S into
the outer northern waters today, followed by a cold front moving
SE across the northern waters tonight through Sun. The front will
then move SW away from the central waters Sun night, as ridging
returns to the outer northern waters, and the coastal trough
rebuilds along the northern and central California coast. The
coastal trough will persist through Mon night then gradually
weaken Tue through Wed. It will dissipate Wed night as a cold
front moves SE into the northern waters.
