What was the reason for upgrade? I've heard that it was based on the lofted tanker that was thrown some distance away from its point of origin, but I've also heard tht some of the tree damage was upper-echelon as well.
I honestly can't believe the drought is finally over. And have happened in SOUTH DAKOTA of all places. Insane.
Also, what does this mean for previous tornado ratings? I know that Mayfield and Tuscaloosa threw multi-ton railroad containers some distance as well, which might mean that they are elligible to be rated EF5 on the scale. Not 100% positive though.
