ELI5: Why is the temperature usually less cold when it's snowing?
gpt
If it's snowing that means there is cloud cover. Cloud cover acts as a blanket over the land and holds in heat. When there are no clouds the heat from the ground can radiate directly out into space. That's why it tends to be colder with no clouds.
