Thundersnow?

[DMartin]

I saw this cell developing as I left work near Glen Rose Tx, It had a precip area that was very akin to what I've normally seen on Thunderstorms. Except it was pure white with the front lighting from the setting sun, Unfortunately I did not have my camera with me. So raced home to grab my camera and attempted to catch back up with this cell/storm. At the time it appeared to be over Cleburne, TX around 7pm CST. Heres a resized photo. I'll add the couple more I took once I get them loaded onto my webpage.

Excuse me if this is just a normal snow generating fluffy cloud. Im not a weather expert nor have I ever experienced much winter weather. Although I feel ive gotten my share in TX this year!

It's tough to tell from that photo alone, but it certainly appears to be a legit convective cell. My big question would be; Was it definitely snow and not sleet?

I've seen some spectacular electrical activity from sleet producing convective cells. Convective snow is less common. Whether or not it had lightning is anybody's guess though.

Ive seen cg's in heavy snow so it's very possible but like Dave said very rare.

We get thundersnow nearly every winter up here in the Great Lakes before the lake freezes up. Last year we even had severe storm warnings with some of them due to the winds associated with them. Ground temp was a balmy 19 degrees. At 5000 feet, the air temp was 55. Makes for an interesting weather situation. These convective thundersnow cells can look as impressive as some plains cells complete with anvil and flanking line.
