A 984mb low off the Aleutian islands will begin to weaken a ridge of high pressure that has been over the area for the last week or so.
A change in the weather pattern will bring a series of disturbances to the South Coast mountains resulting in moderate snowfall for the next several days. Freezing levels should spike Thursday with cool arctic air returning by the weekend.
