Wow!  This is definitely getting a 1930s vibe if you ask me.  Another possibility is this is a transition from the big warm run we had 2014-2016 and we will eventually settle into persistent cold.  Sometimes transition periods can have wild fluctuations.

It's interesting that even the heat waves this year were different than what we've seen in recent decades. Like the 105 in August and 98 in September...neither had happened since the 1980s at PDX.
