A cell developing over the southern portion of LUB CWA showed a Lignting Jump value of 6 sigma. Upon further investigation it went from almost no lightning (2nd image below) to  a flash density of 35. The storm proceeded to quickly pulse down (with a  decrease in lightning). Thus…the sigma 6 in this case was not indicative of severe. The storm followed the same trend as most of the isolated convection in LUB today.

One suggestion with the Lightning Jump Algorithm/pGLM data is to be able to display a time series as is done with the ENI Lightning Data. Another idea to better gage trends in Flash Extent Density and Summary products is to show previous values when sampling with the mouse pointer (or a change in value from previous reading).
