At least 16 deaths were blamed on the storm as it swept across the nation's eastern half, including three people who officials said died at least partly because of the extreme cold.

The heaviest snow fell north of Boston in Boxford, which received nearly 2 feet. Nearly 18 inches fell in Boston and in western New York near Rochester. Lakewood, N.J., got 10 inches, and New York's Central Park 6. Philadelphia got more than 6 inches.

Temperatures reached 8 below zero in Burlington, Vt., with a wind chill of 29 below, and 2 degrees in Boston. Wind chills there and in Providence, R.I., made it feel like minus-20 Friday morning, and the forecast called for more of the same into Saturday....
