An upper level high pressure ridge  (Shaded “Arch” shape with blue arrows) continues to move eastward and behind it is a strong trough of low pressure (Shaded “U” shape with blue arrows) that will keep us in turbulent weather for a while. A  frontal system  will move through between tonight and Saturday. Cold air behind that front will drop snow levels to 1,000 ft. Saturday. No accumulation is expected on the valley floor.
