I think it actually warmed up overnight. We woke up to oppressive heat. My bike was sitting directly in front of my room and I took my saddlebag outside to put on the bike and the hot, steamy air condensed water all over the saddlebag almost instantly. I have to tell you, the heat was unbearable. By this point my chain had developed some slack so a took a few minutes to tighten and lube my chain.
