I rode my bicycle to the gym this morning, and it was very cold outside, around 15F. But while I was working out I saw a local TV forecast of 60F for the afternoon.
This created a dilemma for riding to work, balancing being underdressed in the morning vs. overdressed in the afternoon. I guessed wrong – temperature at 1:40 pm is only 36F. The weather experts missed the forecast by more than twenty degrees.
