Snow for Halloween?

It seems like only a few days ago I was hearing about all the snow that had fallen in Denver. It seems a bit early for that. I know it snows in the mountains earlier but now they are talking as much as 10" out east. It sounds like New York and all the eastern states are going to get blasted with snow. They call it a Noreaster storm. I have heard they can get quite bad. With wet heavy snow, many trees will probably come down along with the electric lines. It is way too early for this to happen before Halloween but we have had light snows in the Midwest at this time before. But nothing like 10" of snow.
