Abstract: A system that predicts current tornado activity has been developed. The system includes a processor that receives model data from a meteorological data source that indicates tornadic activity and generates a model data tornado potential index. The processor also receives radar data indicative of tornadic activity and generates a radar data tornado potential index using weighted values assigned to different components of the radar data, where the components of said radar data comprise, a tornado vortex signature (TVS) data value, a mesocyclonic activity (MESO) data value, a precipitation and intensity (dBz) data value, a vertically integrated liquid (VIL) data value, and hail size data value. The processor further generates a composite tornado potential index using weighted values of the model data tornado potential index and the radar data tornado potential index and stores the index in an electronic data storage media.
