Default "Thundersnow"

Hey I got thinking the other night, saw some "thundersnow"... Not even sure that's the technical term for it but I know I don't see it often...

Anyone experience flying through it? Just curious what's the dangers. I'm assuming there's not "connectivity" to the storm... But I'm guessing it's still bumpy... Fill me in so I can decide if I want to penetrate next time

It's a thunderstorm.

That makes snow.

I was skiing once when the lifts had to be shut down temporarily due to thundersnow on the mountain.

Saw it a few times when I lived in Colorado Springs. The snow has lower reflectivity than rain, so it won't look as bad on radar.
I also saw it snow with a temp of 10c there too.

Do you mean "convectivity"? As in "convection"?

Yes there is. It's a thunderstorm in sub-zero conditions. Precipitation sublimates from vapor directly to a solid. Same process that creates snow instead of rain (or freezing rain, or ice pellets), except it's convective instead of stable.

Don't fly through it.

Yup it's just a thunderstorm ,,,,few years back coming home empty in early evening, didn't have the radar up until we saw what we thought was a flash of lightning? I was dumbfounded? Came down thru the last layer of haze and sure enough there's cumulus build ups ! Had to ask for deviations to get around a line as if it were mid July!
