Where in Colorado doesn't it snow?

All of Colorado does get snow at one time or another.

There are some states where it only snows in part of the state with higher elevation, so that is a good question, but Colorado is far enough north that it does get snow across the entire state at one time or another, although it snows more in the mountains.

Snow doesn't usually stick for a long time in Colorado though, unless there is a huge blizzard. Other times it melts after a few days or a week (depending on how much snowfall there was), and then it is dry and sunny again.
