I was surprised when I did not see an ENI DTA cell polygon around the storm in southern Mountrail County. The two strong storms further south both had polygons, but this one did not. I noticed this storm was also strong with high reflectivity values aloft and some rotation. The 1 min cloud flash ENTLN lightning plot only showed one flash associated with this storm. The total lightning detection efficiency is only around 40% in this area which may explain why there was very little lightning associated with it. Since there wasn’t an ENI DTA cell polygon, I couldn’t look at the time series. This example showed me that it’s important not to rely on this data. It would be nice if the lightning detection efficiency were higher in this part of the country or equal across the entire country.
