SYNOPSIS
High pressure across the N and central waters will gradually weaken to the W and NW of the area tonight. A coastal trough will expand S along the entire California coast on today. Another cold front will move over the N and central waters late Sat and Sat night, then stall over the central and S waters Sun into Mon night. A low pressure system is expected to track S towards the N waters later Sun night. The low and associated cold front will slowly drift S and SE Mon into Wed. High pressure will build back in Wed night.
