What term describes a rare winter storm that includes thunder?

• A. Thunderstorm
• B. Thundersnow
• C. Snowstorm
• D. Hailstorm

Answer: (B)

Thundersnow describes a rare winter storm where thunder and lightning occur during snowfall. This happens when a snowstorm has strong convective updrafts and enough moisture to create electrical charges, just like in a summertime thunderstorm, but in a cold air environment. The lightning discharge then produces thunder, which can be heard even though the precipitation is snow. The sound is often muffled by the snow and cold air, making it less dramatic than a typical thunderstorm.

This fits best because the key feature is thunder occurring within a snow event. A regular thunderstorm involves rain and warm air, not snow; a snowstorm is just falling snow without thunder; a hailstorm centers on hail rather than lightning in a snow context.
