A little over a year ago a category F1 tornado went about a block and a half North of my house.
We heard the tornado sirens and got in our basement.
The rain and wind was getting stronger, then (as if someone flipped a switch) it just stopped. After a minute or so I went up stairs and everything seemed OK.
My wife went and sat in the living room looking out the window and asked, "where are all those people going?" I went out and saw some trees down a little over a block to the North, that's when we knew something had really happened.
Not the only incident
A few years before that a Micro Burst (which is almost a tornado, but the wind goes in a straight line) came right through our block. The worst of it hit about 150 feet north of us. It came out of nowhere, the weather was very nice otherwise. The tornado sirens sounded less than a minute or two before it hit.
Both of those left a very visible trail of destruction, neither of them sounded like a train.
