Jon Bonk is a meteorologist with the National Weather Service in Portland. He told KLCC there’s a lot of moisture coming into the southern Willamette Valley Saturday night into Sunday morning…
“…but the temperatures may not just be cold enough to bring snow to the valley floor. There’s a better bet of that happening from about 1,000 ft. elevation and above, the challenges are going to be: how cold does it get and do we get that accumulating snow below that 1,000 ft. level?”
Bonk said with Tuesday’s forecast, it’s entirely plausible to see snowflakes mixed with rain settle on the valley floor. But that’ll depend on the amount of cold air.
