A Snow Supercell! With Thundersnow and Mammatus Clouds April 21, 2021

[@user-ts8um7uz2u]

Ethan, Nice capture of a snow supercell !

[@EthanBWeather]

Thank you Neil!

[@jamestreft5570]

Heheh that radar image looks familiar! Good catch bro!

[@EthanBWeather]

Haha it should! Thank you for providing it, because that's literally the only way I would have been able to see what happened that day. And thank you for watching!

[@wholelottaweather24]

Hmm, awesome video, I always imagined a snow squall with 60+ mph winds, I guess this is what it would be called😁

[@EthanBWeather]

Thank you! I'm sure it had some gusty winds in the core (which I didn't intercept because I didn't know what I was looking at).

[@jonathanschlack7210]

Awesome video. Here in PA, on April 21, 2021, it reached 72° at noon, then after 12:30 PM, I got a thunderstorm with 45 mph wind gusts, dropping temps from 71° at 12:30 PM to 53° an hour later, then was down to 41° at 2:30 PM. Then that same evening we got snow showers.

[@EthanBWeather]

Thank you, Jonathan! I didn't know it was a wild day of weather over there as well.

[@jonathanschlack7210]

@@EthanBWeather yes it was a wild day. It was my first real thunderstorm of 2021.

[@Warcrazyness]

Interesting, didn’t know snow supercells were I thing, I wonder what it was like inside them, quite windy?

[@EthanBWeather]

From what I understand, they have conditions similar to those of snow squalls (heavy snow, windy). I'd love to see some research done into these unique events.

[@studiodewolf]

Snow supercell? That is interesting and rare.

[@EthanBWeather]

Indeed! I had no idea they even existed until I saw some members of the Storm Chasers of Ohio team talk about them (they got a much better video of one than I did).

[@kamilandre1]

Super hailstorm, great video.

[@EthanBWeather]

This cell produced some small graupel along with snowflakes, but I'm sure conditions were worse within the precip core.

[@bryantrackhurricanes1367]

Snow supercell? huh weird, I'ma do research

[@EthanBWeather]

Yes, please do, and let me know if you find out anything. I've done a little bit of searching, and have yet to find anything which specifically addresses this phenomenon.

[@carypyke935]

Great & informative..thank you Sir

[@EthanBWeather]

Thank you for watching!

[@tylerparsons6042]

It’s called the thunder snow there was absolutely no rotation in the video A supercell thunderstorm does not produce snow lol

[@EthanBWeather]

Thundersnow is a separate phenomenon produced by some convective snow showers/bands; the thing in the video is producing thundersnow but it is not thundersnow itself. Also you can't see the rotation because of the elevation of it and the density of precip from my position; it was visible on Doppler radar SRV imagery, and you can see a visual example of it in a video by the SCO group. You're right, supercell thunderstorms do not produce snow; this is not a supercell thunderstorm.

@@EthanBWeather Get your facts straight bro

[@EthanBWeather]

@@tylerparsons6042 I do have them straight, dude.

[@EthanBWeather]

@@tylerparsons6042 I'd be happy to explain additional aspects if you'd like.

[@treasurevalleytrackside9527]

​@@EthanBWeather If it has upward rotation wouldn't that classify the storm as a supercell?

[@celeno31]

😍🤩👍

[@EthanBWeather]

Thanks!

[@tylerparsons6042]

There’s no such thing as a snow supercell lol

[@EthanBWeather]

I don't know what you would classify these, officially, but here's what we do know: they have been documented more than once (refer to the Storm Chasers of Ohio for clearer footage); they have enhanced convective elements compared to surrounding snow showers; and they display a weak rotational signature in the updraft as seen on velocity imagery. Us chasers who have seen them, therefore, refer to them as "snow supercells".

Says who?
