Widespread accumulations of 3-4” of snow have been observed from Eugene and Springfield down past Roseburg this morning, with lighter accumulations up towards Albany and Corvallis. A few more snow showers may linger over the next hour for the Willamette Valley, and perhaps closer to the noon hour for the Umpqua Basin. Skies will begin to clear with some sunshine this afternoon, helping melt some snow, but high temperatures will only reach the low 40s. With clear skies tonight, temperatures will plummet, and a few teen degree readings are not out of the question for much of the I-5 corridor tomorrow morning. Any melted snow and moisture on the roads will freeze, and the Friday commute could be quite treacherous. Another system arrives Friday afternoon. After some moderation of temperatures, precipitation at lowest elevations looks to be in the form of rain. However, the snow elevation will still be at 1500’, with significant accumulations of snow possible in the Cascades. Rain showers will continue through the weekend, eventually becoming more isolated by Monday. Temperatures will remain below average through the forecast period, with snow levels rather low into next week. The middle of next week looks uncertain, with a slight chance of rain and showers heading into Wednesday.
Pass Conditions: Chains or traction tires are NOT required across the Santiam Pass but ARE REQUIRED across the Willamette Pass at this time.
Have a great Thursday!
