Yesterday heat advisories were issued for Miami-Dade and Broward counties. Late in the afternoon, I went out on the balcony to read. Because of the cloud cover, there had been no sun for a few hours, so it was not unbearably hot. In fact, after I had adjusted to the warm embrace, after the air-conditioning inside, it felt rather pleasant being outside. Then a soft rain started to fall, which cooled things down even more. I started to feel a little uncomfortable in my T-shirt and went inside for a long-sleeved shirt.
