??Well, a blizzard watch IS something serious.
They don’t issue that for less than life threatening conditions any more.
What Defines a Blizzard?

“Officially, the National Weather Service defines a blizzard as a storm which contains large amounts of snow OR blowing snow, with winds in excess of 35 mph and visibilities of less than 1/4 mile for an extended period of time (at least 3 hours). When these conditions are expected, the National Weather Service will issue a “Blizzard Warning”. When these conditions are not expected to occur simultaneously, but one or two of these conditions are expected, a “Winter Storm Warning” or “Heavy Snow Warning” may be issued.”
