Default Snow / Disconnecting Antenna

Hello folks,

I've read for many years of how one should always disconnect the
antenna when it snows. I'm curious, though, as to why snow is
something that would be of particular concern. I guess the concern
over thunderstorms seems straightforward enough...that lightning
strikes, even at some distance away, can result in significant,
potentially damaging static voltages in the antenna. But does/can
atmospheric conditions during a snow result in this same sort of
phenomenon?

As an aside, related or perhaps not, in the areas of the U.S. in which
I've resided, I've only lived through one thunder-snow.

Anyway, just wondering about that.

Static electricity is caused by the snow hitting the wire. If you use
an unbalanced transformer on your antenna and the low side is
grounded, you're OK. The good radios have an UnUn built-in.
