In Iron Man 3, Tony Stark went to Tennessee to investigate the strange death of a woman there.
The state was shown covered with snow, like that's Montana!
According to this site, Tennessee is in the place of 41st out of 50+1 states in the aspect of getting snow.
Also, I remember a quote from Luis, Scott Lang's best friend from Ant-Man and the Wasp:
We live in California, not Minnesota!
And California is just two below Tennessee in that website.
