So the Greenfield tornado, at 309mph is now the most powerful tornado in recorded history by minimum possible windspeed.
Maximum windspeed it's still beaten by the 2013 El Reno tornado and the 1999 Bridge Creek-Moore tornado, but it's solidly in the top three.
It's still at a prelimenary EF4 rating, which hasn't been finalized, but the EF scale doesn't always correlate with windspeed, since it's a damage scale.
Either way it was a scary looking beast that made wind turbines crumple even though the main funnel was half a mile away from them.
