Chasing solo this day and targeting an area from Aurora to York in southeast Nebraska, which was just northeast of a cold front/surface trough intersection,1. the first tower developed just to my west at 5:15 p.m. The tower soon fell apart though, but not before producing an elevated funnel.2. Finally, an LP supercell developed to my west near 7 p.m. and began moving northeast along the stationary front.3. The cell continued to organize and lower its ambient base, and as I got into a decent viewing position near Giltner, Nebraska, a wall cloud began developing.4. Positioning myself under the base, intense cloud-base rotation was noted,5. and a couple of short-lived funnels formed.6.; 7. As the RFD began punching around, a large, multi-vortex gustnado formed and persisted for a minute or so before gusting out.8.; 9. The meso continued to organize and lower as the precip core intensified and the RFD continued cutting around the meso.10. Tracking the cell on a myriad of dirt roads, it produced a large dust-whirl tornado that persisted for a couple of minutes near Stockham.11.; 12. As I finally got into a better contrast position to observe the tornado, it dissipated.13. With dusk approaching and the loss of daytime heating, the cell began weakening. However, a new cell developed to the southwest and produced a nice display of anvil crawlers before it also fell apart.14.
Much appreciation extended to Dave Lewison for excellent nowcasting throughout the day.
