  • On June 4, 2022, the most favorable area for supercell development looked to be a region just south of a warm front situated in southern Nebraska. While wind shear and large-scale forcing were not particularly strong, high instability, steep mid-level lapse rates, and low-level directional shear was enough for discrete supercells to form in this region as I approached. Of the 3 storms that dominated, the westernmost appeared the most promising. I quickly cut under a new developing updraft to get to the west of the storm as it moved almost due south. A few areas of rotation were noted under a new cell developing just south of the parent storm. However, the primary mesocyclone was approaching from the north. As it got closer, a well-defined wall cloud and RFD cut were noted. In fact, there was even a brief area of rotation (pointed out in the video) at ground level. Technically this was likely a very weak and brief tornado. As the main updraft region approached, I escaped to the west, getting blasted by the RFD as I did so. I then paralleled the storm to the west as I drove due south until nightfall. At this point the storm displaced a large HP supercell structure. As sunset occurred a rainbow developed in the hail core as the rear flank downdraft continued to fan out to the southwest, pushing out huge plumes of dust along the storm's western flank, making for a stunning display.
