If you built a snowman during the day the snow only needs to be below freezing. It can get colder that night or the next day by quite a bit. The exterior of the snowman would be colder than the inside even though they’re both frozen.

This is kinda how igloos work. They hold the heat from the ground below and the occupants inside. The interior is cold, but not nearly as cold as the sub-zero temperatures outside.
