Nicest weather today in months. Yesterday it was very hot, with another record high (99). Took it easy on my commute home. Overnight a cold front moved through, and what a difference today. I left late (9:45) due to a doctor's appointment, and it was only 75 degrees with low humidity. Had my fastest commute in months, averaging almost 17 mph, without really pushing it. When I got to work, I realized why I was so fast when I saw the flag outside our building -- apparently I had a pretty strong tailwind all the way to work. Hopefully the wind will shift or die down for my return trip this afternoon.
