Mind you, this was at about 1915. I have a temperature display on one of my toolbars, and I've been watching it creep up all evening. When it hit 103°, I reckoned it was a good time to take a look at a more reliable source, and that was when I saw the heat index was so high.
I actually do not mind this high a temp when the humidity is so low. I feel like a lizard; I could just lay on a rock & bask in the sun. I cleaned the front half of the house this afternoon, in fact. Not bad at all.
