Alright, maybe NYC is a little Warmer than Chicago

Since moving to New York from Chicago, every time I mention to New Yorkers that Chicago is a much better city, without fail they almost always reply, "But Chicago is so cold!"  I have brushed this off as a parochial New York-ism for some time ("But isn't everywhere west of the Hudson cold and miserable?"), feeling that in my experience in the two cities, they're both about the same amount of cold.  New York is at 40.7N, Chicago is at 41.8N---this is all of 60 miles, or about an hour's drive difference.  I'd hardly believe that amounts to a significant change in temperature.

But today, I decided to actually check data and play with a new charting tool.  Here's what data source World Climate has to say about it:
