Wow, that is pretty cool to see. I know you don't get it too often. We have a saying over here. It goes something like this "big flakes little snow, little flakes big snow. Basically when the flakes are larger the accumulation isn't as much. When they are small we get several inches.
Once it stopped it melted away pretty quick. Do you talk about it being 'too cold to snow'? I'm not sure if that can be true.
I think it is possible. It's not something we really think of too much though. When we had those -30 degree days a couple of years ago there was very little snow if I recall. It was just horribly cold.
I did consider making a comparison to Snowpiercer in the post as I've just finished the current series :) It's not that bad.
