Ah, I remember this saga is a good one!

https://en.wikipedia.org/wiki/Thundersnow

Thundersnow, also known as a winter thunderstorm or a thundersnow storm, is a thunderstorm in which snow falls as the primary precipitation instead of rain. It is considered a rare phenomenon.

there is a greater likelihood that thundersnow lightning will have a positive polarity, which is associated with a greater destructive potential than the more common negatively-charged lightning. That said, lightning is far less frequent in a thundersnow storm than in a summertime storm, and is usually of the cloud-to-cloud variety, rather than a strike that travels to the ground.

It’s rare, but it could happen.
