I think it’s pretty obvious now, with daytime temps consistently rising into the 50s over the past several days, that we’re done with any kind of wintry weather for the season. So it’s time to pull the fork and […]

Great post Karl. I especially liked your reasoning for the “real” winter for the Pacific Northwest.
I’ve always wondered what November 1955 was like… I remember from when I was a kid seeing super low record lows on the KOMO newscasts during mid November and being in disbelief. Here’s the temps at Sea-Tac from that stretch of November 1955.
11/11: 38/15
11/12: 21/13
11/13: 23/14
11/14: 23/9
11/15: 24/6
11/16: 31/21
11/17: 31/23The reanalysis data from NCEP has the textbook arctic outbreak pattern for the PNW – I’m still trying to figure out why this air mass was so cold though. Sea-Tac got 1.4 inches of snow on the 11th and didn’t get any more until 4.6 inches from an overrunning event on the 17th. The lack of snow makes this event all the more impressive.

Karl Bonner commented on the post, A Review of Thursday's Snowstorm and a Forecast for Tonight, on the site Charlie's Weather 7 years ago
The most memorable snowstorm of my early childhood in The Dalles was of course late November 1985. Temps as cold as -1F a couple days before Thanksgiving, too….
Then there was the 1992-93 winter season, where the cold and snow lingered throughout late February and the first few days of March.
The El Nino season in 1997-98 had a big…[Read more]

This really is a classic pattern for snow – I wish it was occurring just a few weeks later! At this point, I think The Dalles will see flakes while PDX will just get rain, or a rain-snow mix. Perhaps the West Hills could get something. Monday morning is still a LONG ways out though.

Karl, being rather new to the PNW (nearly 4 years), it is certainly interesting to experience the “early” winters here, especially having grown up back East (where winter is still occurring as I type), then being 16 years in the San Francisco area (where summers are “late,” maxing in September/October). I look forward to your next blog on this subject. Though I am a snow lover, I am ready for Spring to hit full-force.
The year 2011 was an interesting one, in that our hottest weather of the year came in early September (much like parts of California often experience!). Also we had a ton of low-elevation snow in March 2012. Sometimes the “normal” seasonal timetable gets skewed…
