I'm publishing a link Monday morning (after end of week data comes in) and it will update weekly. I'll provide the link here.

I haven't been collecting weather data of any kind. Certainly an interesting variable and I know there are sites that allow you to go back and get the weather for a city on a particular date, but I haven't been collecting any weather data.
