Why are temperatures typically lowest around sunrise?
Just like your household budget, the Earth has an energy budget. During the day, energy arriving from the sun exceeds energy that the Earth radiates back into space, so temperatures usually rise. At night, incoming solar energy drops off, but the Earth continues to radiate energy, so temperatures typically fall. Dawn comes after a full night in which the Earth has lost energy and received very little, much like the day before your paycheck arrives and your bank account is at its lowest.
