I think these borderline events are where we see the effects more. We probably would have seen these borderline events be snowier in the 495 belt especially and possibly towards the coast. It's just speculation of course, but in some instances 1C would have made the difference, especially inland.
But I would argue even in the days of yore, that overall hemispheric pattern would have sucked. You're not going to get a ton of snow with that look even if we were a bit cooler. Cutters still would cut.
