Chicago knows its snow, and we've been known to get a lot.
On Monday, during a storm that could drop up to eight inches of snow, the area could get something more: thundersnow.
Thundersnow? Yeah, the term doesn't get thrown around a lot because it's a rare event.
Check out the video at the bottom of this post to understand just how stoked meteorologists get about this phenomenon. The Weather Channel's Jim Cantore reacts to hearing some during the Chicago Blizzard of 2011.
NBC Chicago meteorologist Alicia Roman likens it to a thunderstorm that pours snow instead of rain. That means we could see a burst of snow and a lot of it.
Roman said several dynamics are involved to produce this, namely a warm surface temperature, cold air high in the atmosphere and enough strong wind to move all that warm, moist air skyward really fast.
Roman says thundersnow usually occurs in late winter and early spring when ground temperatures are warming up.
