Weather for 24 International Cities by Zonination

I picked the 24 cities based on a balancing act of the following criteria:

• Cities with data-rich sources (some of the best historic data happens to be provided by international airports in the US, so I exclusively used those)
• Cities with high populations (helps with the international airport thing too)
• Cities that are evenly spread throughout the geography of the US. Here's a map of the US cities I used.
• Cool (and, well, hot) anomalies like Alaska, Hawaii, and Siberia.
