The only term that I have heard applied to this phenomenon is thundersnow.

It is a rare occurrence, because the wintertime atmosphere is more difficult to yield instability.

When thunder and lightning occur during snow, it indicates a strong updraft, just as one would find in a summertime thunderstorm. However instead of heavy rain, heavy snow is the result.

In this situation, snow (or sleet) can accumulate at a rate of several inches per hour.
