The powerful winter storm that swept across Michigan Wednesday night included rare thundersnow. The processes that make thunderstorms don’t happen often in cold situations. A large winter storm can have the thunderstorm-making process, but Wednesday's thundersnow around Kalamazoo was even more rare because it was caused by the lake-effect process and not a large-scale storm system.
