Heavy snowfall as a variation of lightning storms for frozen biomes

*Normal biomes have two unique climates (rain and thunderstorms) , and I think each biome type deserves at least two climates to enhance the gameplay and scenery.

*For frozen biomes, we already have normal snowstorms as rain. But what about thunderstorms?

*My idea is heavy snowstorms.

*During heavy snowstorms, any mob not in a shelter would be affected by the freeze effect (unless it was wearing leather armor).

*The snow would be heavier and leave larger piles of snow, and freeze water much faster

*Only the frozen undead mobs would survive during the heavy snowstorms

*And of course... they would be as rare as a lightning storm... to be fair.

*And the player would also have the option to sleep to skip.
