The mountains tend to interfere. First, they block moisture coming in necessary to fuel tornadic thunderstorms, called the rain shadow effect. The mountains themselves may even interfere with the tornado-producing mechanisms within a storm. Additionally, on the west coast the winds come off the Pacific Ocean, which has a cold ocean current off the west coast. Not only does cold water provide less moisture to fuel storms, but it also tends to stabilize that atmosphere, while thunderstorms require an unstable atmosphere to form.
East of the Rockies the warm Gulf of Mexico provides the necessary moisture.
