Usually roughly October through May, going by latitude. Snow outside that window does happen.
The snowing or not snowing label comes from the weather model at the camera's exact coordinates and is refreshed about every hour. The model can be wrong, which is why the live video is on the same page.
Yes. The live map shows every camera, and the Snowing now only filter shows just the ones where it is snowing.
At this latitude winter days are short, so the camera can be dark for much of the day in midwinter.
