The cold front and associated precipitation should clear the Eastern Seaboard by early Tuesday...however...cold Arctic air ushering in over warmer lake waters will set the stage for heavy snow bands downwind of the Great Lakes. An upper ridge centered over the West Coast will keep weather quiet in the western U.S...but a Pacific system inching towards the coastline could bring precipitation into Northern California by the middle of the week.
