If you point it at the sky away from the sun on a warm but cloudless summer day it will read well below freezing, the clearer it is and the less moisture/haze in the air the lower the temperature reads.

That mirror will work well where it's mostly cloudless, clouds are going to get in the way of getting rid of heat by infrared radiation though.
