.SYNOPSIS FOR CALIFORNIA WATERS...A trough along the California
coast will persist through Sat night. Meanwhile, high pressure
centered over the southern waters will extend a ridge NE across
most of the region through Tue night. A cold front will move
across the northern waters early tonight before stalling and
dissipating later tonight. Another stronger cold front will move
S across the northern waters Tue night, briefly stall across the
central waters Wed, then lift back N through the northern waters
as a warm front Wed night. A high pressure ridge will reform over
the central waters Thu and Thu night while a cold front moves
slowly S into the northern waters. The ridge will shift S Fri and
Fri night as the cold front accelerates S into the central
waters. The front will slow and weaken Sat and dissipate by early
Sat night. Low pressure will approach the northern waters from
the W late Sat night.
