Say you store a vehicle outside all winter, if there was an usually cold week, say -20 degrees Fahrenheit for example, is it possible for the car to be colder than the -20 since it sat weeks prior to the -20 temps?

Yes.
Clear night, radiation to the vault of the sky (a close approximation of a black body that absorbs all radiation) cooling the surface. Metal has a high emissivity and is most prone to it. It causes condensation (which can freeze) on the inside of metal roofs on buildings.
It can also cause black ice (frozen condensation/dew) on tarmac roads when the air temperature is above freezing.
Ther time ouside isn’t very relevant, the sheet metal doesn’t have enough mass to make much difference.
