How come I rarely, if ever, see thunder/lightnings during snowstorms and only during rainstorms?

Because the way snow storms are generally formed is different than rain storms. Rainstorms are usually tall clouds that produce lots of upward/downward motion. All of that motion rubs ice particles together to create an electric charge, and then once the charge gets strong enough it finds a path to the ground. 

Snow storms are usually much flatter and don't produce the upward/downward motion, so little to no charge builds up. The snow also acts as a sound insultor, so even if it does happen you will only hear it from within a few miles compared to lightning in rain which will be heard from 20 miles away or more.
