"The goal of this study was to develop an objective method to estimate the probability of large hail for use in forecast operations. Since the WSR-88D algorithms also produce a POSH, the locally produced method was verified in comparison to determine if the local regression equation was more accurate. Since Billet et al. (1997) used data from a WSR-88D and an upper air sounding that were co-located while this study did not, similarities and differences in the results from Billet et al. (1997) are discussed"--Introduction.
