Is it ever too cold to snow?
No. It can snow at incredibly cold temperatures as long as there is moisture and some way to lift or cool the air, according to the National Snow and Ice Data Center.
However, most heavy snowfalls occur with temperatures of 15 degrees or warmer near the ground, according to the center. Air can hold more water vapor at warmer temperatures.
The center is part of the University of Colorado Cooperative Institute for Research in Environmental Sciences.
