I live in Scotland, so no where near that cold or much snow. But making sure it's got the minerals to keep microbial growth going should help it generate it's own heat. We can buy a product called rock dust here, it's ground up volcanic basalt - side product of quarrying - wide range of minerals in it. Mixing some through before covering it should help.
Another thing that gets it cooking is wood ash, needs to be a pure wood fire obviously. You can also go the extra step and make biochar to mix in - you'll get some ash with that anyway.
If you live near the coast a bit seaweed is a good addition too.
I try to turn my own compost regularly and it's gratifying to see the steam rising on a cold day ๐
