At what temperature do tornadoes form?

Tornadoes can form when there are significant temperature differences in the atmosphere, typically when warm, moist air at the surface rises and meets cooler, drier air aloft. This instability is often found in conditions where surface temperatures are around 70°F to 90°F (21°C to 32°C), combined with strong wind shear. However, tornadoes can develop in various temperature settings, as the key factors are the interaction of different air masses and atmospheric conditions rather than a specific temperature threshold.
