I've said it before and I'll say it again, PDX, SEA, and EUG are about even in significant snows events the last 15 years:
EUG: March 2012, December 2013, February 2014, February 2019, December 2021
PDX: February 2014, January 2017, February 2018, February 2021, February 2023.
SEA: January 2012, February 2017, February 2019, February 2021, December 2021
5 events each of 6" or more. PDX proper is 6 but I left February 2019 off since that was east of I-205 only.
