El Reno Tornado lightning - becoming the widest tornado in history.

Was at Dave Croan's place watching a video and we revisited the El Reno tornado! I have not seen much of Dave's footage but I was astounded to see for the first time his footage of the development of a wall cloud to the birth of the El Reno tornado! The time it took is 2 minutes! We watched this developing wall cloud almost from few clouds to rotating wall cloud that dropped a tornado in 2 minutes! This is something both he and I have never observed before - such was the incredible and dangerous dynamics of the day!
