I'll kick this off with screen grabs and short snap video of the best lightning strike I saw on Thursday evening in Norwich. It came over in 2 separate waves, the second the most violent of the two, with wind gusts, large convective drops and loud thunder including a positive strike (the thunder I got on video). I hope to upload the whole video to YouTube soon.
Finally a decent heat breakdown for us that was worth while. Lightning was very frequent.
