EUGENE, Ore. - A cold air mass moved into Western Oregon on Tuesday, bringing snow to the Cascade passes through Wednesday night, the National Weather Service said.
"As colder air moves in, snow levels will lower as well," forecasters said. "Snow levels will lower to around 3,000 to 3,500 feet by Wednesday morning," forecasters said.
"With showers continuing to move onshore and good westerly flow, we could see accumulations close to the 6 inches per 12 hours rate required for a snow advisory Wednesday," a NOAA weather watcher in Portland opined.

"Thanksgiving day will likely be dry, but morning fog will probably linger in the valleys," forecasters said. "The next Pacific front will move in Friday bringing more rain and mountain snow to the Pacific Northwest."
The worst of the wind and flooding rains appear to be over, however.
"Additional rain is already moving in off the Pacific from the next system," forecasters said Tuesday. "This next system will be weaker and colder than the last, so high winds are not a concern.
"Another cold wave of low pressure will move onshore Wednseaday morning followed by a ridge of high pressure coming in from the south," forecasters said. "There may be sufficient south-north pressure gradients for gusts to 50 mph along the coast but damaging winds are not expected. Winds will also be gusty inland with this system, especially near heavier showers."
