How it is made[change | change source]

  • A thunderstorm at the front of a wave of cold air or warm air (cold front or warm front)
  • The edge of a big ocean storm (or cyclone) where lower warm and higher cold air mix.
  • Thunderstorms going over a warm lake while the air is cold (or lake-effect).

Thunder can be heard many miles away, but thundersnow thunder can only be heard a few miles away. The snow stops sounds of thunder more than rain.
