That was the more destructive area yesterday. However it wasn't the only area struck by tornadoes. There were 51 tornado reports yesterday as seen here. Those numbers could tweak with time.

More strong to destructive tornadoes are possible in the southern Plains later today. East central Oklahoma and parts of Arkansas could see this problem later today. In addition to that significant tornado threat, very large hail is expected. Same can be said tomorrow for the same area as the tail end of the frontal boundary will hang around for awhile.

Yes, this was a very sad day. I was in severe weather mode with the boss yesterday and talking with chasers in the field. Chasers reported two destructive, large tornadoes down side by side at one time. Between 8-9 pm there were 17 touchdown reports. A meso-low and a triple point phasing coupled with a mid and low level jet max with veering profiles caused this event. Most of which came from LP supercells (mini-supercells). This was unexpected by SPC, but we saw some of it coming....not the damage to this extent though. Today will be another very active day, and if you guys would like to help with getting information I will allow some in conference with our nowcasting team this evening. Today looks to be a classic setup for a tornadic event in the southern plains. I don't think one state will see the 40+ tornadoes that IL saw on yesterday in a slight risk though. SPC was slacking....they should have issued an update in the evening to HIGH as all of this was being reported on the ground IMO.
