I'm not sure how the light could be related to the temperature--it's possible, but it could also be a total coincidence. Your car must still be under warranty, so I'd take it to the dealer and have them pull the trouble code and fix it. Shouldn't cost you anything to do that, even if it's a minor evap problem or if the extreme cold is causing some of the sensors to read conditions out of spec.
I would recommend a trip to the dealer. Since your car is an '07, it is most likely still under warranty. Extreme cold can do strange things to cars and sometimes things don't appear until the temperature drops. It's a good idea to let the service adviser know that this happened when it got cold so they can pass that information along to the diagnosing tech.
In extreme cold temperatures as stated, many emission components can trigger the Check Engine lamp. Examples are O2 Sensor Heaters, Coolant temp stays cold too long (possible defective thermostat), Evaporative Emission Components sticking due to freezing temps. Have a Dealership find the diagnostic code for what triggered the MIL Lamp. Don't overlook a loose Gas Cap!
Have your EGR system tested. Mine started the same time, when it got cold.
