Well, I'm not a meteorologist, but got some basic theory in my second major (Geography) a third of a century ago. And there was something in the local paper two days back, but I can't seem to find it now. Lessee if I remember this ... A warm front pushes cold air back like a retreating wedge, but a cold front rolls in like a big wall. So if the cold front wall is really tall, and the warm air it meets is moist, then you've got warm wet air being pushed up high and fast, and that can lead to thunderclouds with condensation falling as hail and snow. I think. Anybody out there who can confirm or correct this?

Anyway, whatever the explanation, it's pretty exciting to watch. And hear. I'm right near some big antennas here, so the thunder was BIG and came right after each flash, which reflected off white snow. What a show!
