ELI5 Why do I never hear thunder during a snowstorm?

I've never heard a snowstorm with thunder before.  Is there something about snow that prevents it from being like rain in that lightning and thunder can accompany it?

Thunder is caused by lightning discharging. Generally, lightning requires wet air to conduct the electrical potential from high up in the sky to the ground. Dry air isn't very good at conducting electricity.

During the winter, when it's very cold, the air cannot hold that much water. Most of the water will condense and fall as snow. Since the air is very dry, it is less likely to successfully conduct the electricity from the sky to the ground, so lightning is quire rare. Since lightning is rare, so is thunder. However, "thundersnow" is a possibility and has happened before. Again, it's just uncommon.
