The first significant prolonged snowfall for Central Oregon is headed our way. A winter weather advisory will be in effect from 3pm Wednesday through 10am Thursday. “In the Bend area, we could be expecting anywhere from three to five inches of snow with locally higher amount, locally higher amounts near the crest. So as you head up an elevation north and west of us we could be talking about amounts higher than that, maybe seven or eight inches of snow in those areas.” Weather Channel forecaster Mark Thibodeau says there would be blowing and drifting. The snow will be warm and wet, so it could cause a problem with trees and power lines. He also calls this "heart attack" snow so if you have a heart condition be careful as you shovel it because it will be heavy. We could feel the impact of three separate snow systems by the time the weekend arrives. The first heavy one will arrive within the next 18-hours, followed by a smaller one, and then possibly some more significant snowfall by the weekend. Temperatures will drop overnight after some daytime melting, so you can also expect some slick roads.
