Technically, for a storm to be a blizzard, it must have these things: wind speeds of over 35 mph and low visibility (under 1/4 mile) for at least three hours. So you could have blizzard from blowing snow, even if no snow is falling, and you could get a ton of accumulation without it technically ever being a blizzard. (Whether it's a snowstorm or a blizzard likely won't matter to you if you're trapped in it, however.)
Myth: It can be too cold to snow
But there could still be something like snow. "There actually is no such thing as too low a temperature for some sort of ice crystal to form and for such crystals to settle out and land on the surface," explains Fred W. Decker of the Oregon Climate Service at Oregon State University, in an interview with Scientific American. "Such a deposit of ice needles is not usually considered 'snow,' however; in the Arctic, for instance, we might refer instead to an ice fog."
Myth: Alcohol keeps you warm in cold weather
In an emergency situation, drinking brandy from the cask around a rescue St. Bernard's neck is a bad idea. Alcohol makes you feel warm by dilating blood vessels, but it actually lowers your body temperature by drawing heat away from your core, which increases your risk of hypothermia. But, much like "losing heat through your head" myth, drinking alcohol often makes people feel warmer, so if you're safe on your porch and you want a hot toddy, it will seem to "warm you up." Speaking of...
Traditional winter signs that don’t actually predict anything
There might be a lot we can learn from folk traditions, but man, they get a lot of things wrong too. The following are some folklore sayings about winter that seem dubious:
Squirrels with very bushy tails means a cold winter: Like the vegetables, the thickness of a squirrel's tail is generally determined by how healthy and fed it was leading up to winter. More nuts in summer means beefier squirrels.
Weird myth: This winter storm was manmade and designed to freeze a gigantic sea serpent
The weirder corners of the internet are spreading the theory that the Biblical beast Leviathan has awakened, and the winter storm was created by us to freeze it in its tracks. Their evidence is satellite photos which seem to show a gigantic serpent shape in the Atlantic Ocean. As much as I'd welcome a Biblical sea monster rising from the ocean to seek retribution—all hail Leviathan!—it's unlikely to exist. I'm 99.9% certain (still have some hope) these were natural geological formations seen on Google Earth being mistaken for a sea monster as a result of pareidolia, the human tendency to see patterns in random data. Also: We can't control winter storms any more than we can control hurricanes, even if we were about to be eaten by a sea monster.
