Temperature difference has little effect - it's wind shear. Wind shear (particularly in the hot months) has really declined.

Wind shear is needed for tornadoes. That's why peak tornado season is in spring, not the summer.

Another factor is that some areas get so hot and humid these days, when there is ample wind shear storms grow upscale too quickly because of the abundance of energy. Large tornadoes particularly will not happen after storms merge into a line.
