The ground heats/cools the air, therefore the higher the thermometer, the greater the lag in it mirroring ground temp.
So, if you approach a cold night, the ground gets cold first, then cools the air. However, the next morning as temps increase, the ground warms first and then warms the air.
If memory serves - which it doesn't too often.
