Utlility of Lightning Jump Detection algorithm in providing situational awareness on total lightning increase.

At 2241z…LJDA…detected a 3 sigma jump with the storm of concern. (Fig1)  At that time ENTLN data reported 177 cloud flashes…only 9 of which were CG. (Fig2)  Then at 2250z ENTLN reported 351 flashes…4 CG. (Fig3) The LJDA provided good situational awareness on this doubling of total lightning count and subsequent intensification. which based on 65-70 dbz reflectivity at 25000 ft was valid. (Fig 4) The other interesting note…is that most of the lightning was IC and not CG. CG data would have told you very little about this storms intensification.
