Why it snows when it's warmer

It can never get too cold to snow, but it does seem to snow more when its a bit warmer. This is because it is harder for cold air to form snow clouds. Cold air can't hold as much water as warm air can.

Clouds form as air rises and cools so the water condenses out. If there is enough water in the air, rain or snow begin to form.

Since cold air is denser than warm air, it tends to sink rather than to rise. This means that its harder for clouds and snow to form when its bitter cold. If it does rise, there may not be enough water to form snow.
