Where can I find the dates of the first snow for every year in Chicago dating back to 1975?

Question

Please do not answer with "google" or "weather.com" but rather I would appreciate any actual webpages that have the specific dates.

Answer 1

I can't find this for you on the web for free, and I'm sure you looked. But in the world of meteorology, what you're looking for is called historical climate data.
You can easily find summary data, e.g.,
http://www.ncdc.noaa.gov/ussc/SCoptions?state=1111&short=11,
and because tables with the average or earliest snows of x" depth are available, someone must have the data that produced these tables. That's what you need to look for. And the best way to find it is to try contacting people who are connected with the agencies producing the data. They can probably guide you to this data.

Here are some places that probably have the data you're looking for, or would know where to look for it:
http://www.sws.uiuc.edu/atmos/statecli/General/illinois.htm
http://www.ncdc.noaa.gov/oa/about/ncdccontacts.html#CLIMATE

This site requires a fee to access data, but it may well have what you want:
http://mcc.sws.uiuc.edu/

And if you're lucky, the Tribune might comment on the history of the first snow on its weather page when the first snow happens (or if it's really late in coming).
