The amount of people already spiking the football on twitter on 10/7 is crazy. One meteorologist from PA (no, not JB or Henry) is calling for the coldest and snowiest winter ever in history for the east coast. I’m not a fan of this index or Cohen and I think it has lead to monumental busts over the last 10 years, but you have to wait until 11/1 to really judge how well or not well Siberian snowcover ended up. It’s the entire month averaged out like you said
