Greetings Fellow Texan - I live in the downtown Austin area and I can second your conjecture that concrete and asphalt absorb heat. Here is a downtown weather station: https://www.wunderground.com/weather/us/tx/austin/KTXAUSTI1820 https://www.wunderground.com/weather/us/tx/austin/KTXAUSTI18... This site allows you to check various weather stations and see temps as recorded at the location. You can compare your location to others less or more urban and see this while its happening. Next time you're awake at 3AM with nothing to do check it out! Compare downtown Austin to the suburban area of your choice. I saw a 2-3 degree difference pretty regularly last I looked.
