On The Riley & Scot Show, we have always been amused by The Weather Channel's Jim Cantore's over-the-top love of thundersnow.

What's thundersnow?

From Wikipedia:

Thundersnow, also known as a winter thunderstorm or a thunder snowstorm, is an unusual[1][2] 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.

There are usually three forms of thundersnow:

  • A normal thunderstorm on the leading edge of a cold front or warm front that can either form in a winter environment or one that runs into cool air and where the precipitation takes the form of snow.
  • A heavy synoptic snowstorm that sustains strong vertical mixing which allows for favorable conditions for lightning and thunder to occur.
  • lake effect or ocean effect thunderstorm which is produced by cold air passing over relatively warm water; this effect commonly produces snow squalls over the Great Lakes.

Now that you know what it is, have a look at Jim Cantore reveling in it:
