It does seem between 2015-2023, SeaTac averaged an extra 1-2" than Portland. Portland Airport averaged 7.1" (compared to a usual 4") while SeaTac Airport averaged 8.4" (compared to a usual 6")
I guess I overestimated how much they got. But the airport always gets less too. I remember some freak snowstorms there in 2017/2023 there that these totals don't seem to show.
And I guess 2025 and 2026 got us more up here... So we're even here.
22-23 was great in the sense we had snow like every 2-3 weeks from late November into late February. Only problem was it was only 1-2 inches every time.
February 2018 was decent here…had about 3.5” over several days. December 2016 through February 2023 overall was pretty insane. My old location in Tacoma averaged roughly 12” of snow over 7 winters. Double the long term average.
2023 was only the biggest bummer for me. Can't believe I got under a foot total from one of the best La Nina events we will probably ever see in a long time, while pretty much everyone else got whooped by massive snowstorms. It was like 9-10 inches total. SeaTac got 8. Barely above average. Ironically I almost got the same amount this winter.
I also remember getting extremely disappointed in 2018 where all the snow went south and north. Olympia/Tacoma did well in some of these years while we got almost nothing up here.
