WB latest EPS on PNA. Anecdotally, when I see the PNA at -3 or lower, it just can't get cold enough at our latitude for snow....but notice it bumps up to near -1 around NY week and the control actually goes positive. At that point, a negative NAO could work some magic and pull some cold air down with the AO neutral and the WPO negative. EPO is not favorable NY week.
