I got intrigued by this, but also got nowhere!! NOAA reports report heating and cooling days, which I think are probably using a base temperature of 65F. I cannot find however where the base temperature is set up, or even how the NOAA template manages to evaluate tags such as day.heatdegree.sum (or something like that) which I see being used in the template.
Baffled and also now eager for an explanation/better description from Tom and the gang. I suspect however that if the base temperature could be set/adjusted a modified NOAA report would provide the detail you require. However, even then I do not see how one can graph a reading evaluated for the NOAA reports. There must, surely, be a way - but like you, I remain baffled and awaiting someone else's input to this fascinating thread.
