Ja, if it's too cold the air can't accommodate any moisture. So no moisture, means no snow.

@Xuan12 Technically that's wrong... Snow doesn't happen with the [i]humidity in the air[/i] of the coldest air mass... When the air gets colder, it's able to hold less humidity and so [i]condensation[/i] happens as a result. That condensation causes clouds and ultimately, snow. Yes, colder air is dryer than warmer air because it can't hold as much humidity, but if a super cold air mass with 0% humidity clashes with warmer air (which, being warmer, will contain more humidity), then all that humidity will condensate and eventually freeze, causing snow...
