This was one of the last few visible cloud-to-ground events from a weakening, west-southwestward-moving storm cluster that had moved off the higher terrain east of Phoenix and north of Tucson. In real time, these two discharges flickered quickly, but not simultaneously, appearing to sidestep each other. Their thunder was one continuous report resonating for a long time across the desert floor. By then, a haboob (with lightning) had blown through, storms already were getting undercut by outflow, it was nearly midnight, and I was getting tired after a long day of exploring and hiking on Mt. Lemmon prior to the electrical show. So I shot this and a couple of lesser flashes with gratitude, before packing the gear and heading back to a Tucson motel for good sleep.
