Weak System/ Sun Sunday
A weakening frontal system over the south coast will give the chance of flurries to the alpine today. The next low pressure system will spread snow to the region overnight through Saturday afternoon most of the moisture will be well to the south in Washington state, and the cascade mountains.
A ridge of high pressure will give mostly sunny skies on Sunday. Another front will spread periods of snow to the alpine on Monday with a more direct hit resulting in locally good accumulations, a few flurries will linger into Tuesday morning.
Temperatures in the alpine will remain cool through mid day Monday. Freezing levels should stay between 500 and 700m throughout the forecast period.
Winds should increase to strong from the NW as the system passes through.
