Winter Storm. Blizzard has a specific meaning:

  In the United States, the National Weather Service defines a blizzard as a
  severe snow storm characterized by strong winds causing blowing snow that 
  results in low visibilities. The difference between a blizzard and a snowstorm 
  is the strength of the wind, not the amount of snow. To be a blizzard, a snow 
  storm must have sustained winds or frequent gusts that are greater than or 
  equal to 56 km/h (35 mph) with blowing or drifting snow which reduces 
  visibility to 400 m or 0.25 mi or less and must last for a prolonged period 
  of time—typically three hours or more.
