Earlier this week we had a snow forecast that could really have affected our operations here at COSI. I was watching the weather forecasts really closely to determine how much of the possible 10 inches of snow we could get here in Columbus and one of the forecasters mentioned the possibility of thundersnow. This is a term I've heard of before, even experienced but I really don't know a lot about it. So I turned to our resident science guy extraordinaire, Steve Whitt and asked him what in the world is thundersnow? How does it form and what is it?
