I like this shot because of the layers to it. The wispy look on the top, the shelf cloud in the middle and the sunset and lightning on the bottom.
Another one of my favourite shelf cloud images comes from that same Kansas shelf cloud on May 24th, 2018. As it got closer, multiple layers began to develop.
The image turned out slightly blurry, but that's because the RFD winds were hitting the car at over 60mph and rocking the car. May 29th, 2018. Near Buffalo, Oklahoma.
