An upper level high pressure ridge (“Arch” shape on the yellow line) will take control over the Pacific Northwest through the rest of the week. An upper level low pressure trough (“U” shape on yellow line) will take over by sending a frontal system to Oregon bringing the chances of rain back for at least part of the weekend as the rain should return Saturday night into Sunday with another wave possible on Monday. The snow levels will come down low enough to increase the possibility of some serious mountain snow, but it doesn’t look like it will be enough to help the skiing operations. So far at least, the snow should stay away from the valley floor. Mt. Ashland is closed now due to poor snow conditions. Hoodoo is officially open (as usual closed Wednesdays). Willamette Pass will be open on a limited basis for the upcoming weekend Friday, Saturday and Sunday. Please check their web sites for the latest details and updates.
