An upper level low pressure trough (“U” shape on yellow line) will take over by sending a frontal system (shown offshore) to Oregon bringing the chances of rain back for the second half of the weekend as the rain should return by Saturday night and there will also be snow mixed in with it, then another wave on Monday which could have snow levels down low enough to give us at least a dusting of snow on the valley floor and possibly a couple of inches between 500 ft. and 1,000 ft. before it turns to rain Tuesday. Mt. Ashland is closed now due to poor snow conditions. Hoodoo is open (as usual closed Wednesdays). Willamette Pass will be open on a limited basis for the this weekend Saturday and Sunday. Please check their web sites for the latest details and updates as the new storms could improve the snowpack for skiing.
