What a day this one turned out to be. Definitely one of the top scenes of the summer for me in Arizona. I had been chasing around the Camp Verde area earlier and saw a little rotating storm, then headed north of Cottonwood to watch this one roll off the mountains. It was a bigger cell earlier but as it came over the mountains, it split into two and the left side suddenly became this brief but gorgeously sculpted mesoclyclone. I was freaking out at the time and I have the entire genesis of the storm on time-lapse (which you can see in my Monsoon II film).
This was a shot with my third camera and a lightning trigger…you can make out the bolt there on the right side of the cell.
Hoping to get lucky and see more of this kind of thing next summer!
