After sweeping across the road just to my northeast with blustery force, this fast-moving, outflow-surfing, post-cold-frontal supercell emerged into sunlight with spectacular effect, flashing a brilliant mid-afternoon rainbow for a long time and many miles, near to far. Post-cold-frontal? Yes, supercells can happen in any environment where enough lift, moisture, instability, and shear exist, sometimes even behind a cold front. This was about midway through the storm’s lifespan, and with no roads suitable for keeping up, I simply let it race away in the surrounding clean, blue sky, appreciative and thankful for the gift of splendor.
