That sound is the wind blowing through the trees on the ridgetops. Wind doesn’t make noise unless it encounters a resistant force i.e. an object.

This is demonstrably false. Have you been sleepwalking through the last 7+ years? The vast majority of noteworthy cold outbreaks and lowland snowfall since 2018/19 have occurred as a result of SSW/PV disruption events. You do better with cold onshore flow because you’re up in the terrain, but that’s not true for the majority of posters here. Perhaps that lived experience is warping your memory.

I still think the secondary low on Friday needs to be watched very closely. The 06Z NAM shows some strong winds in my area and the HRRR shows it too but not as strong as the NAM. If I remember correctly, the NAM was showing some strong winds for the first low but people didn't believe what it was showing so it caught people off guard. Yes, some of the winds on the NAM didn't happen (like for the Willamette Valley) but it doesn't mean we shouldn't be prepared. Now that is out of the way, let's talk a little bit about the extended forecast. When it comes to trying to understand what the models are showing you have to remember, the further you go out, the margin of error increases. What I'm seeing in the models is a pattern change. We won't know until we get closer to the event. The models know something will happen but don't know the fine details, yet! The models will flop from time to time in the next few days and that's to be expected, so don't give up on them yet. OK, I'm going to try and get a little bit more sleep before work. I'm still having pain in my left leg from the sciatic nerve. I worked yesterday and it went well until I had to stand for about 30 minutes. That's when the pain came back and that's why I'm awake now Good night

00z ECMWF ain't looking half bad. Neither is the EPS.

I was hoping someone could explain it. Thanks! I could hear the wind above last night... sounded like a constant airplane noise overhead but never really surfaced. The ECMWF should be able to recognize the difference but it clearly showed a gap wind scenario hitting NB the hardest. Gap winds out here in the valley can easily gust to 60 with no power issues. And if there are issues it's quickly resolved because it only impacts a lightly populated area like NB and Snoqualmie.
