Do you really think this will be a mountain wave? I thought you needed a mid level wind reversal for that. The models show we don't have that this time.

That area is horrible with east wind situation.

I had to go downtown Portland for a doctors appointment because I'm still having a lot of pain from my sciatic nerve and when I left there wasn't any wind but I'm at the DMV to get a temporary disabled placard and it's breezy now. 🌬

How close are the hills to you? Because under the right conditions (especially stable boundary layer) upstream terrain will help mix wind down. Out here the strongest winds (outside high elevation areas) are immediately downstream from high terrain.

Would look quite different for the PNW if January were removed...or replaced with December.
