I decided that the weather will become cold gradually, even though in a matter of twenty four hours it dropped 40 degrees. The first day it was 50 degrees out, I wore a tank top with a long sleeve shirt over it. The second day it was 50 degrees out, I wore a short sleeve shirt with a jacket. The third day it was 50 degrees out, I wore a long sleeve shirt and a sweatshirt.
This way, even though it's getting colder, it's also getting warmer.
