EUGENE, Ore. - The first snowfall of the season has hit Central Oregon at the Santiam Pass late Friday/early Saturday, marking the arrival of the first winter storm weather.

"Colder air will nudge the cold pool aloft further south about every 12 to 24 hours over the weekend, bringing significant shower activity to the region," National Weather Service forecasters in Portland said Thursday.

Forecasters Added in Saturday Mornings reports  that the snowfall seen at high elevations could continue through the weekend.

"Snow levels will rapidly drop behind a cold front this morning. This will result in light snow accumulations for the higher Cascade Passes of the Central Oregon Cascades today." the NWS reports.

The ground's warmth could keep much snow from piling up during the day, but by Saturday night and Sunday morning snow levels will remain below the passes.

This isn't a major winter storm; forecasters don't expect much more than a couple inches at pass level, with showers ending Sunday afternoon.

The timing of the storm could complicate viewing of the Orionids meteor shower, which peaks overnight Saturday into Sunday.

Forecasters said that they predict off and on showers through next Wednesday.

"The models indicate that snow levels will remain down near the cascade passes, potentially dropping even a bit lower at times," forecasters wrote. "Expect cloudy and damp conditions with temps running several degrees below normal through the extended period."
