10:45. The sun is normal to the empty oven, and the oven is at 462 degrees. Air temperature in the shade: 98 degrees. (A bit on the cool side, actually. Again, I live in the foothills of the Sierra Nevada, at Latitude 36-28.)
13:15, just after the sun's peak elevation. I should have taken a picture of the thermometer at 10:45. A high layer of cirrus clouds has covered the sun and reduced the temperature to just over 375 degrees.
