Two systems affect parts of the country through the weekend producing several inches of snow potentially.

The first system in the east will intensify as it moves northeastward close to the Atlantic coast producing mainly rain for areas close to the coast with a gradual transition to ice and snow the further west you go. Ice accumulations will be possible before a changeover to snow from north-central PA northeastward to southern ME, and snow accumulation over 4 inches possible from north-central WV to northern ME with the highs totals possibly over a foot coming from north-central NY to northern ME. 

The second system will move from the Pacific Northwest today eastward into the Great Lakes by Sunday with the best chances for several inches of snow coming in the Cascades and the north-central Rockies today and Saturday, east-central SD and southern MN Saturday night into early Sunday, and then central WI Sunday and Sunday night.
