Higher temperatures increase the the maximum capacity of water vapor that can be in the air , Lower temps decrease the maximum capacity of water vapor that can be in the air. This will have a direct correlation to the amount of snow fall.

Therefore, the colder it gets the less water vapor there will be in the air. Transversely, the warmer it gets the more water vapor there will be in the air.

Water vapor in cold temps = snow..
This builds up on the open water and on top of the ice pack resulting in more ice..
