It turns out that Weather.com doesn't actually track the temperature of Hell, Michigan. Instead, it references the nearby Pinckney, MI forecast. However, we can safely say that the temperature must be close.
Today, Monday, MLK Day, Pinckney is 13 degrees. That's in Fahrenheit.
So, I think it's safe to say that what everyone always said was true - that a Black President would happen as soon as Hell freezes over.
