Perhaps "coat" and "jacket" are more ambiguous in the United States than the United Kingdom. If it's cold enough to warrant it, I wear a jacket in the morning. If it isn't, I don't want to have to carry it around all day. Checking the daily weather forecast is too much work, so I just go by the current temperature in the morning, which leads to many false positives.
