The mountains of Washington and Oregon will be digging out from the first big snows of the Autumn season. A storm system moving in from the Pacific Ocean will bring heavy, wet snow to portions of the Cascade and Olympic ranges. Snow levels will drop to around 3000 feet, where 3-6″ of snow is likely. At the highest peaks, more than a foot will fall.

A Winter Weather Advisory has been posted for the mountain ranges in Washington and Oregon.
As of this morning, the snow had started near Mt. Hood, but most other areas were dry or just seeing rain.
Snow will begin to develop across the region throughout the day and as cold air is pulled down behind the low, snowfall rates will increase. Snow showers may linger through the rest of the week into the weekend, but the heaviest period of snow will be tonight into Wednesday morning.
The National Weather Service in Portland is using all forecast techniques and a little humor too as they watch this storm move into the region.
Good question, @antipex. Larry Chicken continues to employ the latest forecast techniques. #NWWinterWX16 pic.twitter.com/Yx6H267PSK
