@psuhoffman Great post. Have a question though. I was digging through some of my older posts and have noticed a similarity with extended NAO looks. Below is 300+ hr forecast for the EPS gor Jan 13 showing a very nice west based block and fast forward to today and it is more centered as an east based NAO. It’s been the pattern it seems all winter. I’m curious to what too look for to make sure we get the retro west that has been seen in the past but failed so far through January.
