Why doesn’t it thunder when it snows?

Thunder is also possible when it snows in winter. But the probability of occurrence is very small.

Thunder and lightning generally appear in strong convective weather. For example: convective rain that often occurs in tropical rainforest climate zones and in summer afternoons in my country, and typhoon rain that often occurs on the east coast of low-latitude continents, are often accompanied by thunder and lightning.

The place with the most thunderstorms in the world is Bogor (tropical rainforest climate) on the Indonesian island of Java. There are an average of about 322 thunderstorm days every year, and it is known as the "Thunder Capital of the World".

Strong convective weather requires warm and humid air to rise rapidly. In summer, the temperature near the ground is easy to rise rapidly, so strong convective weather - thunderstorms often occur.

There are few chances of strong convective weather in winter, but sometimes strong cold air moving south can also cause warm and humid air near the ground to rise rapidly in some areas. Snowstorms often occur at this time, and it is normal to be accompanied by thunder and lightning.
