The coldest I'm aware of was a tornado outbreak in SW Oklahoma on February 22, 1975. Several F2 tornadoes formed in the early morning hours when temperatures were near or just below 40 degrees Fahrenheit. There have been other incidents of severe thunderstorms and tornadoes when temperatures were in the 40's and occasionally even the 30's.
Theoretically a tornado or severe thunderstorm could form at any temperature so long as atmospheric instability is high enough, but the levels of instability from the parent storm system required to form a tornado at say, 25 degrees, would be much higher than anything experienced on Earth.
