It was extremely warm for a 7am commute (75F) and I'm still commuting in jeans because I don't want to bring extra pair of shorts (I bring a pair of fresh unders though). It was a fast commute though, as I barely had to stop for any red lights (got lucky) - mostly at Washington Circle/K St I get stuck several times but not today - all green lights!
Now going home, it's supposed to be in the 90s...
