Bomb cyclones and polar vortexes—winter's scary weather explained
What creates these dramatic-sounding weather conditions?

It's not the first time these conditions have hit the country.
Last year, it was so cold Niagara Falls partially froze. Bomb cyclones, polar vortexes, and arctic air masses blanketed the region. New England saw hurricane-force winds, Maine and Boston had blizzard warnings, and it snowed in Florida.
