Please add greyish kind of fog to snow event, right now it snows from clear sky with few clouds, though it is possible in nature (I observed this), snow of that intensity is usually accompanied by total (or partly cloudy) cloud cover with heavy greyish look (somewhat distinct from rain clouds, that can look from deep blue (when sun) to white-grey (without sun))
