Nothing particularly distinguished about this time lapse, but I do note for a second time right at sunset the prevailing winds aloft (as seen in cloud movement) go absolutely haywire. The first half of this video has the weather streaming in from the SSW steady as she goes, then right when the lights go out there’s turbulence and what looks like a switch to an offshore flow. My n of 2 is a hoot, but it’s not something I’d necessarily have identified as a pattern before now without time lapse. It’s easily the most suitably dynamic view available without leaving the house.
Any old-time Seattlites with a weather-watching habit like mine, knowledgable sailors, or roving meteorologists with an answer, an observation, or an idea chime in in comments.
