Thundersnow Hits Chicago

Jim Cantore of the weather channel was reporting live from downtown Chicago during the great Blizzard of 2011, when the huge blizzard that dumped two feet of snow and packed 60 mph winds resulted in quite a few bouts of Thundersnow---A blizzard that is packed with lightning and thunder.

In all of my life, I've only seen it twice. It's truly a rare occurrence.
