The properties of lightning cells preceding numerous severe storms in various locations of the contiguous United States have been studied and certain predictive patterns in the lightning cells have been identified. The time evolution of the lightning flash rate and the IC/CG ratio of individual cells are used to identify thunderstorms likely to produce damaging hail, high wind, or tornadoes with significant lead times before they occur. Studies have shown that early detections in the sudden rise of the rate of IC discharges and subsequent peak of total flash rate can serve as an indicator for severe storm conditions. Using WTLN lightning data, a real-time lightning cell tracking and the WeatherBug Dangerous Thunderstorm Alert (WDTA) program has been developed. The results of several storm studies will be presented.
