== Blizzard vs. Winter Storm ==
While the terms are sometimes used interchangeably in casual conversation, a blizzard is a specific type of severe winter storm with strict meteorological definitions.<ref name="ref1" /><ref name="ref2" /> A winter storm is a broader, more general term for any weather event involving freezing or frozen precipitation.<ref name="ref3" /> All blizzards are winter storms, but most winter storms do not meet the specific criteria to be classified as blizzards.<ref name="ref4" /><ref name="ref5" />

The primary distinction relates to wind speed and visibility.<ref name="ref1" /> The U.S. National Weather Service defines a blizzard as a storm with sustained winds or frequent gusts of 35 mph (56 km/h) or greater, accompanied by falling or blowing snow that reduces visibility to less than a quarter-mile for at least three consecutive hours. A winter storm, by contrast, is a catch-all term for an event that produces snow, sleet (ice pellets), or freezing rain.<ref name="ref5" /> It does not have specific wind speed or visibility requirements, and its impact can range from a minor inconvenience to a hazardous event.

A blizzard does not require currently falling snow. Strong winds can lift snow that has already accumulated on the ground and create a "ground blizzard," which can produce the same dangerous low-visibility conditions as a traditional blizzard. A winter storm, however, is defined by the presence of precipitation, whether it be snow, freezing rain, or sleet.<ref name="ref3" />
