Doesn't matter. I've seen us have a big -NAO and still get absolutely nothing out of it. And I've seen us have a +NAO and us get snowstorms out of it. I think the NAO doesn't matter as much as it's hyped.. in my opinion
WB also predicted I'd have normal to above normal snow to above normal snowfall For alot of years and I haven't seen an above normal snow winter since 2015-2016! And that's only because of the big blizzard in January of 2016 Lol
