Eternal Winter is a small mod that enables snow in every biome.
For clients and modpacks
Just download and add the mod and enjoy!
If this mod should be used server side only, you may consult the coremod in addition to this mod to display snow instead of rain on the client. It can be found here
To circumvent the coremod (which may break things), just install this mod on the server and on the client.
