The Winter Storm Warning for the WA Cascade east slopes will be downgraded to an advisory in effect until 3 p.m. this afternoon. 

Columbia Basin snow levels will be around 500-1000 feet on Christmas night (Saturday) with little to no snow. According to the National Weather Service, an additional 1-3 inches are forecast on Christmas night, but heavy snow is possible along the Central OR Cascades, including Mt. Bachelor.
