The northern border of the state is defined by the Ohio River and is relatively flat. The further east and the further south you go, the hillier it gets as you get into the western foothills of the Appalachian mountains. The water table in this region is relatively high as well, since you are essentially in river bottom. The combination of easily available water from both wells and the river, and the flatness and richness of the land allowing agriculture AND the river allowing transport all combined to make this region of the state more populated than the other parts.
There is a “saying” that the storms follow the riverbed (at least here in Oklahoma) and while the saying is not strictly true, this storm system seems to bear it out.
As far as the apparent ignorance/ignoring of the weather, this is not a region of the country where massive systems spewing multiple tornadic vortices is normally assumed. Even here, some people ignore the warnings. Part of the problem is that the forecasts say that it is possible, but we all know the weathermen don’t know what’s happening (/sarc). In truth, areas that don’t normally see these things assume it to be a big wind, and you should be safe inside. Not true. Since this area of Kentucky doesn’t normally see these kinds of storms, underground shelters are not considered necessary and thus won’t be around—besides the water table is rather high and thus one can’t have a basement or root cellar. Additionally the storms hit in the night, making it difficult to know that a tornado is on the ground as you can’t see the debris field. When it hits power lines and/or transformers it will short and thus spark brightly, but in most cases this is about all you will see unless it is backlighted in some way. This is the worst scenario possible, unless one hits during rush hour.
Only time will tell as to how powerful the storms were, as such categorization depends on (amongst other things) assessment of the damage done. Was it one vortex on the ground the whole time, or multiple ones dipping down and rising up? Just because the vortex has gone back into the clouds doesn’t mean that it won’t either send the same one back down or spawn another. The storm track makes it quite apparent in hindsight that the event was massive and potentially deadly.
About ten years ago, we saw an F5 on the ground for 45 minutes, tracked continuously the entire way. This was in mid afternoon when it started forming, and near the end of the track it hit more populated areas. There were portions of its track where it stripped the sod off the ground, the only thing left of a home was the foundation, the news stations were doing nonstop weather (radio too) telling people that the only way to survive it was to either get out of its path or seek underground shelter now. Timelines were given as to when it was expected to enter an area; estimates of the width of the vortex were given (a mile wide, and sometimes two): and there were still people who went outside to see the tornado (broadcast on every local station, so why track it down?) and some went to an overpass to watch the incoming storm. Of course, the overpass was in the path of the storm. Of course, the debris cloud made it harder to see. And of course, these folks lost their lives.
Since then, we have seen tornadoes in areas that haven’t seen one in over 50 years.
Increasing vigilance and increasing warning times, as well as development of severe storm warning systems have saved lives and will continue to do so only if the systems are implemented and people pay attention. I have family in that area, and my heart hurts for the communities there.
