It contained turbulent clouds and strong up motion, but no rotation. The system was progressing northeast faster and I needed to move again, but if I did it could cost me the storm. If anything was going to happen it would have to be in these last few minutes of daylight. The storm begin to form and lift large chunks of condensation into the wall cloud. Give or take a few hundred meters the photography position I had now was the one I was stuck with for end of daylight on this storm.
Experienced chasers know when storm reaches tornadic potential the spin up can happen fast.
That's what happened in this situation. I was forced to change my filming position just a little further north to get a better vantage point of the rotation. At that time the tornado formed. Since clouds were condensing close to the ground already it was only a moment for the funnel to lower. It was a wide condensation funnel, ragged on the front and smooth on the back side.
