You may have heard someone say, “It’s too cold to snow today,” but actually it can never be too cold to snow.
Snow clouds form high in the air, where the temperatures are colder than it almost ever gets here in the United States. Two-inch snowstorms have fallen when the ground temperature was colder than 20 degrees below zero.
But there is a grain of truth in the idea that very cold weather and snow don’t go together. When the air is very cold, it’s usually very dry as well. So it can be too cold to snow heavily, but never too cold to snow.
