- www.kevin-palmer.com - I stopped in Wheatland to grab dinner with a long drive home ahead of me. But when I saw this sunset developing, I knew I had to find a spot nearby to capture it. A severe MCS (mesoscale convective system) had moved off to the east. Underneath the anvil of this storm were mammatus clouds, which lit up like crazy as the sun went down. I've never seen a sunset quite like this.
