I'd never experienced thunder with a snow until a few years ago. I wonder why?

This weather condition is called "Thundersnow" One of the sources I looked up explained that conditions causing this to happen is as follows:
The air is below freezing near the ground, but unlike summer thunderstorms it isn't near the ground air that rises to the tall thunderstorm's top. The instability is only in a shallow layer aloft. In "Thundersnow" the action mainly takes place in a rather shallow layer that is usually near 20,000 feet and only around 5,000 feet thick.
One of these weather conditions happened in Chicago in 2011.
Steve, where were you when you encountered the experience of Thundersnow?
It was here in Pennsylvania, I think it would have been around 2009 or 2010. There was also one here just this year, in November. Both times it was just a few peals of thunder I heard, I didn't see the lightning.
