Wintry weather continues to be possible over parts of the country today from 3 different systems. First, in the northeast, a low pressure system will produce several inches of snow across a good chunk of New England and heavy lake effect snows to locations off of Lake Erie. Next, a warm front  builds into the Plains, bringing a chance of snow to mainly ND initially, with a gradual change over or mix with freezing rain and or sleet. Finally, another trough approaches the west coast, bringing more lower elevation rains and accumulating higher elevation snows from central CA north to WA and east into the northern Rockies.
