All phenomena
Lightning and thunder occurring while snow is falling.
16-Bit Take (analogy): An ice-level scene with an unexpected lightning animation.
The science
Collisions among ice particles can separate electrical charge in a cloud. If the electric field becomes strong enough, a lightning discharge can occur while snow reaches the surface.
How to spot it
A flash and thunder during snowfall identify the event. Lightning safety still applies in winter; observe from shelter.
Where
Snow-producing storms with suitable convective conditions.
Best season
The local snow season.
- ▸Lightning is possible in winter storms, not just warm-season thunderstorms.
- ▸Strong updrafts and mixed ice particles help clouds become electrified.
- ▸Thunder does not establish a particular snowfall rate.
