I remember maybe 15 years or so ago, that we had a similar setup where everything was aligned except for the PNA. And...... we were getting a similar result as we have now. When we got to the end of winter, we heard "if it wasn't for the pacific crashing into the west coast and running straight across the country, we would have been set. I also remember a couple of time when several of the indexes were bad (NAO included), but we had a very strong PNA - the results were we didn't have any sustained cold, but we had chances with timing and eaked out normal snowfall for the season (thought it didn't stay around for more than a couple of days). History tells me that anyone that harps on the need to have a -NAO but is blind to the state of the PNA needs to be taken out behind the woodshed.
Here's to hoping we score big at some point.
