What Should I Wear To Run When It's Cold (or hot, or windy, or...)?

I always struggle with what to wear on a run when it's cold out. I can't stand to be hot so I usually err on the side of under dressing. This weekend, the low is 44, the high is 64, and there's a slight chance of rain. As in all things I have questions about, I did a google search and found this "What Should I Wear" tool. I thought it was interesting so I'm sharing it.
