@Tom Does this have anything to do with your idea of winters getting colder in general at least for the GL's?

Timberline Lodge had a 10” base at one point in February 1977. Winter can be really, really terrible in the PNW.

I knew someone who used to tell me boat stands for Break Out Another Thousand

They can get 100 inches in 7 days easy, they have a good chance they can open.

Not surprising really. True "Flash freezes" are a rare bird. Seen maybe two in Michigan my entire life. Harrison scored 33.6F briefly about 4 pm under filtered sunshine. First time the sky has had that spring-ish warm look to it in forever, lol. Snowpack settling ofc, and roadways etc that had salt and dirty brown really getting nuked. Showers Thursday to rinse the crud away hopefully. Will see how well tho. Liquid events have underwhelmed aside from 3rd week of Oct.
