We always think of thunder coming with lightning in a rain storm.
But thunder can even happen during snow!
One big difference between regular thunder and thundersnow is that the snowflakes falling down make the thunder quieter, so you can't hear the thunder noise from as far away.
The snowflakes are like padding that gets in the way of the sound and keeps it from going very far.
