I did not take note of which TV station I was watching when I saw this and the comments about the perspective of how the shot was taken. They also understood the tornado to be moving away from him.
Argh. I hate tornadoes here. Two Christmas ago, my family and I were in Dallas area visiting for Christmas. The weather was so wild. You just can't see a tornado in dark, but it was big and F-4. Blew the houses away.
My guess is the photo was photoshopped. I saw pictures online from the particular storm in Alberta that looked to be the same except with different foregrounds. Easy enough to just take out one foreground and drop in another, in this case your husband mowing the lawn.
