    Good evening from Bulgaria. It is currently -20C outside and the sky is clear. Now the strange thing, there is stuff falling from the sky like shards of glass. I certainly don't think it is snow, looks more like frost.

    What could it be?

    Yes that's the stuff.

    What is it? What causes it?

    I'll hazard a guess its frozen fog???
    Seeing as non frozen fog is a ground level cloud, I assume frozen fog is a ground level snow cloud where the water vapour is freezing into tiny sharp crystals but there is no journey down to earth where the ice crystals would normally clump together to form snowflakes on their way down.

    Thats my guess. Am I right experts??

    Diamond dust is single ice crystals that form out of water vapour in clear cold air below around -20 °C, although I did witness it here in December 2010 at around -12 °C (probably because of increased water vapour levels in the air here).

    Yes, indeed. There was not a cloud in the sky and it was falling constantly.

    Have seen this many times in Ontario, if you get some calm wind conditions, watch for columns of light that you can see in the ice crystals.

    That 1067 mb high over Russia is extraordinary, there could be some nasty static electricity problems with that, hope the infrastructure holds together.
