You might have seen a lot of talk today on social media about thundersnow with Wednesday's Nor'Easter. So...what exactly is it, and how does it happen? It's far less common to see thunderstorms in the winter months, but if all the conditions are right and we have lightning within a snowstorm, we call it thundersnow. The ingredients you need include lots of available moisture and also instability in the atmosphere. So next time you have a thunderstorm when it's snowing, you can tell your friends you are experiencing thundersnow! https://twitter.com/WeatherNation/status/971514283329597440 https://www.facebook.com/WeatherNation/videos/10156314885854874/ For WeatherNation, I'm Meteorologist Meredith Garofalo
