Moving further out of the 12z EPS, it finally shows a full scale pattern change. The negative PNA would be a distant memory.
Day 10 has good ridging out West with a positive PNA and trough in the northeast.
Day 15 still shows the +PNA with a very good looking deep trough in the east.
If this look holds, we could see a very good pattern for winter storms between the 10th and 15th.
