I'm looking for a historical USA (specifically Chicago, IL) weather forecast dataset. Temperature forecasts would suffice, though the more data, the merrier. I know this has been asked a lot of times in the past, but nothing worked for me. Here's what I found so far:

  • Both links in the accepted answer to this question are broken
  • DarkSky API can't provide historical forecasts, but only historical observations and future forecasts
  • NOAA's Weather Prediction Center archives only provide pictures (either GIFs or PDFs), with no textual temperature forecast data
  • The data in this question doesn't seem to suit my needs (not sure how to parse some of it, and the parts that I have been able to parse don't contain historical Chicago forecasts). The answer to that question is relevant only to Europe, and I need USA weather forecasts
  • The best thing I could find was NOAA's Archive Information Request System and Iowa State Mesonet. Both provided historical weather forecasts for Chicago, but they were both very coarse and verbal. For example, the following paragraph appears in a huge text file: ".TODAY...Cloudy. Showers likely in the morning, then a chance of showers in the afternoon. Highs around 70. Northeast winds 10 to 20 mph. Chance of precipitation 60 percent." This thing would be difficult to parse, and would probably not be worth it because it just says "Highs around 70".

So is there anywhere from which I could get historical data that:
1. Contains Chicago temperature forecasts
2. Is easy to parse (e.g. in csv format)

    I fixed the dead links in opendata.stackexchange.com/a/2013/1511, please let us know if it's useful – philshem Sep 18 '18 at 11:00
  • Thanks, but none of the sites contained historical weather forecasts for Chicago (in a format that is easy to parse). Moreover, I've contacted NOAA's support, and they said they don't have CSV/JSON/any other "nice" format for this kind of things. – ezer1337 Sep 23 '18 at 8:37
  • This is not an answer. I am just typing my question here since I am not able to comment. I will delete this soon Since its been a while, I am just curious to know if you found an answer to your question. – Balamurali N.R Jun 7 at 19:52
