This presentation supplements these recent findings with storm-relative composite maps and soundings from 2006-2014 HSLC severe report subsets segregated by report type, convective mode, and event severity. In addition, these composites will be compared to composite environments of false alarm tornado and severe thunderstorm warnings and radar-based nulls. The goal of this work is to improve pattern recognition of HSLC severe convective events by presenting the typical spatial arrangements of several environmental ingredients. The ultimate aim is to increase (decrease) the associated relatively low (high) probability of detection (false alarm rate) of NWS tornado watches and warnings within HSLC environments by comparing severe event composites to those of nonsevere events.
