Got a link to support that?

My sister graduated from the University of Oklahoma, which is in Norman, the center of gravity of tornado reports in the US, and the home of the NSSL. I went down for a couple of days in mid-May one year for her convocation. The first evening I was there a front rolled through and several funnel clouds formed. During events like that the local TV broadcasters overlaid a local Doppler radar image in the top right corner of their regular programming. All the locals were VERY experienced at interpreting these images.

Kansas is next door to OK and AFAIK gets its fair share, and more, of fronts and severe weather. I find it hard to believe Blighty would get more. Maybe Bill Kuhn or someone else from Kansas could chime in.

Maybe what happens is that the population density in Kansas is low, so some tornadoes go unreported because they aren't seen or don't damage structures (because there is a low density of structures, too).
