Tornado last Friday night?

Last Friday night - early Saturday morning we had a pretty nasty thunderstorm come through.  I was awakened just after 1 am by our county's phone notification system, so I got up and opened my laptop to check the radar.  This is what I found.  

Needless to say, I was quite disturbed by the large mass of rotating air coming toward Iola, and Kate, the boys and I spent the next 20 minutes in the basement until it blew over.  No tornado in Iola, but I've not heard whether Neosho Falls saw anything destructive.
