Stumbled across this yesterday and thought I'd share. Most have been talking about an increase in fuel usage to keep their homes warm (unless significant increases to insulation) and these sites can be used to confirm it. First the explanation of a "Degree Day" for those who don't know what it is. http://www.degreedays.net/introduction And then the site that has the data. http://www.weatherdatadepot.com/ When I took a look at southern NH, using Manchester as an example, I found that we're trending for the coldest winter in 10 years using a balance point of 65 degrees. I'm sure others will find similar results for where they live.
