Hey everybody. I'm new to this site, so PLEASE tell me if I'm doing something wrong. Won't hurt my feelings. I live in South Carolina, 40 years old male, etc etc etc. Today, while flying from Las Vegas to Atlanta, we flew very close to a SC, rotating and beautiful, with vivid lightning. The only reason I suspect it was rotating, was because the clouds formation were completely rounded all around the exterior of the storm. No ragged edges. I THINK I may have been somewhere between the TX/NM border, to the Tulsa area, but not positive. The time was very close to 11:15AM Vegas time, or 2:15PM Atlanta time. This was really a spectacular sight.
