With the EPO going hard negative, not sure how much into positive territory we would want the PNA. The EPO look continues to get closer (ie we arent kicking that teleconnection...it appears real), so a negative pna could even work helping nudge the SER into a gradient zone in the Mid Atl with SW flow events tracking sw->ne along the boundary. Thats with a negative pna or maybe neutral. Strong +PNA with a robust -EPO runs the risk of being bitter cold and dry. Though we always run some sort of risk or another. In short, if the -EPO is real, which it does look to be, I will roll the dice with a slight - or neutral PNA rather than too much of a good thing. YMMV
