What is thundersnow?

Although thunderstorms are less common in the winter, sometimes lightning can occur within snowstorms and is called thundersnow. Thundersnow can be found where there is relatively strong instability and abundant moisture above the surface, such as above a warm front. Thundersnow is sometimes observed downstream of the Great Salt Lake and the Great Lakes during lake-effect snowstorms too.
