Two things can be true at the same time. Not debating the 2 degree warming, but each synoptic setup, although similar, will have some details that are different but important. I'm just not sure this 2 degree difference can be applied across the board. Seems like an oversimplification that doesnt account for the nuances. The current setup may or may not have had a different(more favorable) outcome in the 1970s. Devil in the details- that hasn't changed. The current airmass is almost entirely Pacific in origin with a significantly negative PNA, while the AO is positive and the NAO is neutral. The only decent cold is to our NE, and no real mechanism to involve it in the storm as it stands. Need better than that to somewhat negate the unfavorable Pacific imo. We needed a stronger low with a better track as we saw in several model cycles a few days ago, and dynamic cooling got the lower levels just cold enough for a paste bomb.
