Flights at Philadelphia's airport, mostly arrivals, were delayed about an hour, spokeswoman Stacy Jackson said.
Parts of southern Indiana saw 6 to 8 inches of snow from the storm, some in areas that had received more than a foot from a blizzard earlier in the week.
That blizzard was part of a storm system that dumped more than a foot of snow in some places and has been blamed for at least 16 deaths. It also spawned more than a dozen tornadoes in Alabama, the National Weather Service said.
But Saturday's snow wasn't as heavy as that of the previous storm, the weather service said.
