On the evening of February 18th, 213, it snowed, lightning and thunder in Jingzhou. What is this phenomenon? There is a vision in the sky?

I thundered several times in Wuhan on the evening of February 18th, and then it snowed. I think this is a bad omen. It never thunders when it snows, and it's still winter. Will it thunder in winter? Moreover, the thunder with a lot of anger made me flustered and my house shook. This kind of thunder is not simple! The delay is long and loud, and something must happen.
