.SYNOPSIS FOR CALIFORNIA WATERS...A trough along the California
Coast will persist today. A weak 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.
