Snowfall has little to do with GW. It is -38 here now. That is temperature and is related to GW.
Here in east central Illinois our Christmas ice has melted and the temperatures have been near if not slightly above average. I was afraid the ice would last a month this time of year. I suspect we will see some of your cold in a while, but hopefully moderated some.
I live in Wasilla and it was -25 when I went to bed last night. I am not an old timer but that is the coldest temp since I have lived here. When can an Alaskan finally get some of that global warming algore has promised? I also have more snow piles from clearing my drive than I have ever had by the end of the season. This is going to be a long cold winter.
