}} Thundersnow, also known as a winter thunderstorm or a thunder snowstorm, is an unusual<ref> Dauna Coulter, NASA [1] Retrieved on 12-20-2012.</ref><ref>Christine Dell'Amore, National Geographic News</ref> kind of thunderstorm with snow falling as the primary precipitation instead of rain. It typically falls in regions of strong upward motion within the cold sector of an extratropical cyclone. Thermodynamically, it is not different from any other type of thunderstorms but the top of the cumulonimbus is usually quite low. In addition to snow, graupel or hail falls.
