It looks like there's some artefacts introduced by how the various states report these incidents: some states entirely empty and some inexplicably much denser than their neighbours. I'd expect lightning strikes to not pay much heed to state borders...
A little surprised to see that there were no lightning deaths in Hawaii during this period, as I know a fellow who was struck by lightning while on vacation out there. People sometimes underestimate the danger that lightning poses - make sure to stay safe out there.
