The upper air flow (yellow jet stream and dark colors for winds) shows a  trough of low pressure a (“U” shape) sliding Eastward through Oregon and a low (yellow circle) developing and moving through California as a frontal system moved slowly away from the Pacific Northwest with colder air behind it. Notice that the jet stream airflow has set up a high pressure ridge (“Arch” shape on yellow line) that it brings mostly clear skies and the colder air in from the north and northwest through New Years Day Holiday weekend.
