Why are there so many tornadoes in the southeast these days?

What stands out is that all of these tornadoes occurred in the Southeast. It may be that “tornado alley” once stretched south and east of where it has over the past half-century, but then 40 years of data would not detect that. Such a possibility creates a problem for the theory of global warming.

Where are tornadoes most common in the US?
