Wear a heavy coat

It is cloudy and windy. If I am outside too long I need a coat. I went after food this morning. When I left the house, it was nice; it was not too cold or too hot. Therefore, I did not wear coat. When I arrive at my destination, the air felt cold when I got out of the car. A good think I left my heavy coat in the car last week.
