A wider look at the lightning jump grid at 2234 UTC of the NE Boulder CWA… All tracked storms (with greater than 10 flashes per min and within the 150 km LMA domain) are shown.  Three tracked cells show some type of sigma jump at this same time.  Two in green – 1-sigma (or standard deviation) and one smaller cluster, orange, with a 3-sigma jump.

The three-sigma jump storm corresponds with a ProbSevere 92% and MESH of 1.65 in.
