There were some charts posted by Don S, on the MA forum, which showed a continued downward trend to both snow amounts and the "snow season" at DCA over the last 100+ years. Information like that is hard to debate as much as CC may be. I definitely do not think winter is done for the MA or PA going forward in time (years) but it would be hard for me to argue that the average snow season/cold (avg temps) when looked at per decade or longer would snap back to what was seen 50/100 years ago based on that Don S Tweet. I think there may be more than some credence to your thought that some of our recent (last 20 years) run of big snows could possibly be attributed to some warming in a similar manner to people who say the melting polar cap will make ocean waters cooler.
