The NOAA / National Weather Service has an archive from the Weather Prediction Center, but it only started archiving most products a few years ago:

forecast.io also provides historical forecasts through their API. You can call a past date and time and still get the daily, hourly, and minute forecasts (in addition to actual forecasts). That is, ask for the weather on April 16th and will include forecasts for April 20th in the daily summaries.

boundary files for the United States between 1790 and 2014.
I also found that the Association of American Geographers runs this Historical GIS ...

Building a catalog out of this is really easy (and can be done with just a ...
