Isolated severe thunderstorms developed near the Pawnee radar site and over extreme southern Wyoming during the afternoon hours of 26 May 2006. The RHI scan taken at 2248:36 UTC intercepted one of the hail-producing severe cells in Wyoming. At the time of this RHI, there was no precipitation echo present at ranges immediately beyond the intense reflectivity core. This echo configuration makes the three body scattering echo particularly clear. The characteristic negative values at lower elevation angles and distinctly positive values at higher elevation angles in the three body echo are apparent in the unthresholded field display.
