A couple of storms developed off of the high terrain south of the palmer divide near Pueblo’s forecast area. One even registered a +16 sigma jump. Although looking at the raw data, the drastic jump was probably because the relative sample size was quite small and any strong jump would be portrayed as impressive. Also of note, the +16 sigma occurred just as the updraft split occurred and the cell divided.

The eastern storm did show high sigma gains and the raw data went along with that. The strong lightning jump with 4 sigma occurred just before there was a strong jump in ProbSevere from 75% to 93%. The storm was already warned on based on base reflectivity data, but, it helped confirm that there was, in fact, a warnable storm.
