In a cold biome when it snows, if we go up to layers 316 to 367, only snowflakes appear and rain appears.

In the cold biomes when it starts to snow if we go to an altitude of 316 the snowflakes will start to disappear and the rain will appear but if we keep going up to layer 367 the rain will stop and it will start to snow again.

 

Note: this test was done internally in a cold biome but I couldn't show it because I had to reduce the video size. (Name of the frozen peaks biome).
