Flying into the San Gabriel Valley today there was an extreme temperature inversion where you can see the white layer closer to the ground. This is just the opposite of normal atmospheric conditions meaning the air temperature is hotter up at attitude and gets cooler as you descend into the white haze. It was in the high 90's at 3000 feet and quickly dropped to the low 80's once on the ground. The temperature inversion also traps poor air quality once you enter it. That said, still a nice day to get into the air.
