It is a common misconception that it can be too cold for snow.

Erica's Answer:

When it is very cold here in the Northeast, the cold air usually comes to us from Canada. Airmasses that originate in Canada are called Continental Polar airmasses. Whenever you see the word "continental" describing an airmass, you can automatically assume it is a dry system. So, continental polar airmasses bring us cold and dry air- and often, that air is too dry to bring us snow. But it will never be too cold for snow!
