The little mid-level dry layer should start to erode pretty quickly this evening, so I doubt they'll be much virga. This looks like a pretty orographic based outcome tonight into tomorrow. Probably a lot more light/low topped stuff up against the Cascades and table scraps for I-5.

It doesn't start until the 4 Corners High develops and it's consistently warm with no 555 dm lows that deepen the marine layer to 5000 ft.

So was July 2010

Based on what evidence?

It's just an awful model in general. Especially more than a few hours out. Waffles all over the place.
