Doesn’t look like a sudden downdraft of wind either. Just consistent coming down too fast and hard.
I think you’re right. To my eye, they definitely looked fast. Unless the video rate was not 1x.
Should have been a go-around.
I suspect the pilot realized he was coming fast and in the back of his mind the runway conditions were not optimum for stopping, and figured he had to get his wheels down as soon as possible so he could start braking and using the thrust reversers as early as possible on the runway, so he just went straight down to the runway instead of feathering the landing.
look closely as the camaera pans across...you can see the wind blowing snow across the pavement.
