A single product such as Flash Extent Density provides limited information about a flash and potentially storm behavior. Pairing FED with Flash Area as in this example helps more easily diagnose the long flash through the stratiform region of this storm over northern IA. The higher flash rates associated with the smaller flash sizes along the leading edge of the northward moving complex are more easily explained with the companion product. As the flash extended north into MN and another CWA, this information could be used to enhance DSS since the main convective line was still 50-60 mi away. ENI and other commercial lightning networks would not have alerted to the threat of lightning overhead at such a great distance. An event organizer or EM looking at static radar also may not be aware of the increased threat of lightning well ahead of the main storm band. SCoulomb
