Blizzard-battered New York City is set to get slammed with even more snow this week — proving the groundhog was right. The monster blizzard is now officially one of the city’s 10 biggest winter storms on record. As of 2 p.m. Monday, the storm had dumped 19.7 inches of snow on Central Park in Manhattan, beating out the blizzard of January 2011’s 19 inches, which had held the No. 9 “biggest” snowstorm on record.
