My golfing buddy noticed that in the early morning hours before sunrise it is warmer than just after the sun comes up. The temperature should be rising but seems to take a dip and go down a couple of degrees and yet the sun is now shining. What causes this phenomenon?

Depending on the amount of moisture in the air, cooling will occur. When water evaporates, it's a cooling process, like when you get out of the shower. So when the sun comes up, the air is cooled by the evaporation process, and then warms the land evenly after that. Just like seasons, there is a temperature "lag".

The coldest time is when the sun has been gone for the longest time. The coldest air is close to the ground. When the sun rises, before much heat has reached the ground, the air starts to move, from the changes in wind. So it feels colder.
