Mon through Mon night, while a low pressure trough builds along
the California coast. These features will weaken Tue and Tue
night as another cold front will pass over the N and central
waters Wed into Thu before dissipating Thu night. A coastal
California trough will redevelop behind the cold front Thu into
Thu night.
