IEM is such a fun little rabbit hole to sink into. Especially when things are quiet. Looked at tornado warning counts over the past nearing 20 years (2005-2025). A few things stood out to me in particular right away. 
 

There was one small area in Illinois that has had 0 tornado warnings in the past 20 years, near Dalzell (NNW of Peru) in LaSalle County. 
 

 

Similarly, two small areas in Iowa that have had 0 tornado warnings in same period. One in W Winneshiek County, around/east of Protivin. The other in Ida County around Battle Creek.
 

 

Indiana appeared to have full coverage over the period, which is what I’d expected from IL/IA. MN/WI/MI/OH had several gaps, but again expected given areas reaching further outside the core climatological favored areas for svr/tor. 
 

One interesting part for MN, though, was the boundary between Grand Folks & Duluth CWA. Particularly pronounced between Wadena & Cass Counties. You’ll see it immediately.  There’s definitely more county boundary differences that become noticeable but that one jumped out to me quite a bit compared to the rest of the field I looked at. 

 

 

nice! yeah its a really easy way to spend an hour or two when i should be studying, to waste time. grand forks does seem a little trigger happy on their eastern counties there...
