The day is warmed by the sun. When the sun sets the dark parts of the earth begin cooling. This cooling continues all night long. The longest period of cooling is just before the sun comes up again.
Imagine puting a pot on the stove and heating it to boiling. Turn off the heat for two hours. Now turn the heat back on. The water will be the coolest just before you turn the heat on.

Think this over. You take a thermometer and put a heat lamp on it. It will heat up. You turn the heat lamp off it will cool down until you turn it on again.
The part of the earth you are on is cooling down when the sun is on the other side of the Earth.
It has had the longest time to cool just before day break. Therefore it has cooled the most before the day break.

This is because the area has been without heat from the sun for the longest time. However, a warm wind could blow in before daylight and change that.

In addition to the answers already given, during a calm, stable weather condition, the earth's shadow is the deepest (the least amount of the sun's energy is reaching the earth in your area) in the hour just before dawn.

That's not always true, and if it were, it would be because it just gets colder through the night, then has to stop getting colder when the sun comes up. It's like asking "why is the lost item always in the last place I look?"
