Good evening. Should we see what’s happening in Oregon?
At 1115PM, PT, Corvallis was reporting a temperature of 39 degrees. While Corvallis does not report sky cover, local sites were reporting mostly cloudy conditions. A sharp trough, perpendicular to zonal flow, slices through southern Oregon and his producing a weak area of low pressure, which is generating enough moisture to insist upon winter weather advisories for the Cascades closer to Medford.
The trough is anomalous in its orientation, and will be snuffed out by the system’s attempt to equilibrate. Saturday looks to be in good shape, but a strengthening jet arcing over the Gulf of Alaska is carrying an Arctic wave along with it. Expect some chilly rain to move through, essentially washing out the end of the weekend.

I picked the water vapor today, because it best shows that rotation off shore of Oregon. It actually looks stronger here than it actually is.
