A sky kaleidoscope flashed forth, when a bit of lightning erupted in the upper-level updraft-to-anvil transition area of a supercell. The low-precipitation supercell had offered a splendid sunset scene, and now spun up likely the largest (relative to storm size) midlevel funnel cloud I have seen. Meanwhile, a “ring of Saturn” cloud band skirted the midlevel updraft, nicely collaring the transition zone between laminar (forced) and more purely convective ascent. All of this was set against “blue hour” twilight and a background of broken, textured high clouds.
