Technically, while temperature difference can be a factor in the cause of a tornado - that’s like saying dry wood is a cause for a forest fire.
The temperature difference is the cause for the storms (along with moisture, and instability), that can potentially cause a tornado, but you’re not going to have a tornado without a strong wind shear.
