Carver's spoke of creating an early winter spec thread recently, and after another day in the 70s in August, I figured why not get the ball rolling. This for general long term talk about the potential winter patterns, etc.
Right now, the EPO has went negative, it's at -12, and is in the East descending phase. In 2021-22 it fell into the negative in May and stayed deeply negative until the following May. So it should descend throughout winter.
