With gale-force winds and ice accompanying the snow, some New Yorkers woke up to find their homes encased in thick sheets of ice.

Writing for Weather Underground, meteorologist Tom Niziol detailed a few of the meteorological ingredients for the extreme snowfall: plenty of atmospheric moisture, lots of cool air, and the right temperature and moisture at various levels of the atmosphere for snowflakes to form easily.
