This morning at 5am it was cool and damp, with a steady wind blowing at a 45 degree angle to the road (headwind.) It was a nice ride in.
The temperature climbed into the upper 90's, though, and everyone came into the store complaining about the heat. 45 minutes before heading for home, I bought a Gatorade and stuck it in the deep freeze. It was slush when I headed out.
The ride home wasn't as bad as I feared, though. The wind hadn't changed, and in addition to giving me a push, it made a refreshing cross breeze.

The only bad part was on the initial uphill (I start my trip near a big climb, both directions) I had sweat pouring into my eyes and couldn't see.
