This is our third segment of Weather Explained.
What is thundersnow??
Thundersnow is like a thunderstorm in snow formation. There are four types of thundersnow (info from wikipedia)
- 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 in the comma head of an extratropical cyclone that sustains strong vertical mixing which allows for favorable conditions for lightning and thunder to occur.
- A 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.
- A cold front containing extremely cold air aloft, steepening lapse rates and causing strong vertical movement which allows for favorable conditions for lightning and thunder to occur
Is Thundersnow Dangerous?
Well, do you think a thunderstorm is dangerous? Yes it is.
So, thundersnow is pretty much a thunderstorm with snow instead of rain. So it
s just about as dangerous as a thunderstorm.
