Advisories: NONE AT THIS TIME.
________________
A high pressure ridge (“Arch” shape) has migrated to the East allowing an upper level trough of low pressure “U” shape) to build in from the Northwest behind the ridge. A series of ripples in that flow along with a frontal system will be moving through the Pacific Northwest bringing some clouds, cooler temperatures, and maybe even some drizzle. Temperatures will remain below normal until high pressure can push the low pressure East of us.
