When we have one of those really icy-feeling days, we could end up with wintry hail. But what exactly does that mean?
Wintry hail is not the like the warm, summer thunderstorms that bring large hailstones. Those stones are produced by raindrops going up and down in the storm cloud, growing in size every time they ride the updraft.
In fact, wintry hail doesn't necessarily come from thunderstorms.
All winter precipitation starts out as snow but how it looks when we see it at the ground all depends on what temperatures it falls through.
