Dave,
Welcome to the forum.
Nice sequence of timelapse and lightning bolt barrage in your video clips. Just curious though - was this the 26th February 2008 event? Looks remarkably similar and definitely did pass through the location you live.
You will see a discussion of this event including pictures and perhaps video links
