There was lightning detection map with history somewhere in internet. I tried to find it again, but only realtime lightning strikes maps pop up, that show lightning strikes that happens right now without history. IDK, may be I missed something or historical data was paywalled, but, honestly, I didn't search hard.

Try to find lightning strikes map with historical archive, and you will get perfectly backed answer to your question.

That things looks like that - https://map.blitzortung.org

Very entertaining thing, I would say.
