The temperature was around 20 below Monday morning, when Aberdeen firefighters responded to a mobile home fire.
Aberdeen's fire chief says they're still trying to figure out what caused the fire to start under the home at Park Village. Firefighters put it out quickly and damage was minimal.
Before that, they responded to a car fire in the same neighborhood.
The chief says vehicle fires are more common as the temperature drops and people run their cars for longer amounts of time.
