Heat index: “Over 100 degrees this afternoon” according to local TV news.
(I’m not complaining. Millions of people are, likewise, baking this summer.)
Postscript, Friday 7/27/2012, 6:00 PM: With a heat index over 100 degrees, I worked in the yard (before noon) trimming the dead Topsy-Turvy upside-down tomato plants. Under other circumstances, the plants should have lasted another two months.
