Snow will continue across portions of New England on Wednesday morning as an area of low pressure moves out of the region. Snow is expected to continue across the Northern Rockies through much of Wednesday as an upper level low remains nearly stationary. As another system approaches the West Coast, snow and freezing rain is expected for portions of western Oregon Thursday into Friday. This same system will bring snow to the higher elevations of California late Thursday through early Saturday.
