Tornadoes are least likely to form in association with a warm front, though it can happen.
Tornadoes are least common in winter and autumn.
Tornadoes occur least often in the winter.
Tornadoes don't occur in Antarctica or in areas of extreme desert.
There is no part of Texas that does not get tornadoes. However, they are least common in the southern and western parts of the state.
Yes. Tornadoes can occur at any time of the day or night. They are most common in the later afternoon and least common in the early morning.
Tornadoes are produced by thunderstorms, which get their energy from relatively warm, moist air. In the winter the air is colder and does not have as much energy.
No. F5 is the least common rating. Less than 0.1% of all tornadoes in the U.S. are rated F5. F0 (now EF0) is the most common rating.
Tornadoes, especially strong ones, are are not very common west of the Rockies. In fact, no tornado stronger than F3 has been recorded west of the Rockies since at least 1950.

Tornadoes are generally most common in spring.
A tornado is not necessarily associated with a front at all. Tornadoes will often form along or ahead of a cold front or dry line, and can occasionally form along a wamr front. One common area where tornadoes may form is Larko's triangle, which is near the center of a low pressure system between the cold front, the warm front, and the first isobar. Tornadoes will often form in the outerbands of a tropical cyclone, where no fronts are involved.
