Can objects get colder than the ambient temperature around them?

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?

Um, not enough information given to give an exact answer.

Things can lose or gain heat from temperatures around them.

If you happen to be implying the prior temperature the day before always -30° for at least a short time the car *could* be colder.

I’m going to guess though that something like -20° was in the news and your car has a display that read -25° or something.

I’ve noticed that it seems like car temperature displays are often lower that the local forecast.

Things like where this sensory is in the vehicle end up mattering because there is always a slight variation to immediate local temperature and an area average even down to such a “local” as an individual particle compared to it’s neighbors. It’s just not going to have the *exact* energy of them in any system (based on relative or scale) where energy can be lost or gained anything outside of that group of measurements. And the laws of entropy having equalized it all yet.

Plus factors like wind, moisture, shade (which can vary a temperature by 20° in many conditions pretty easily)

Hopefully I answered the actual question
