I don’t want to go too far down this rabbit hole, but I think our current 7 year winter suckage is a combo of background warming, natural cycles that are unfavorable, and bad luck. We’ve had troughs favoring the west in winter for years now, but up until winter 16-17 it was the opposite with a seemingly permanent ridge out west. Remember the “ridiculously resilient ridge” out west? Sucked for them but we loved it. That cycle flipped HARD. I think that switch will flip again at some point to favor a trough in the east in winter, but background warming will probably mean it’s not as productive as it would have been in the previous cycle.
