1. Western Oregon:
- Coastal Areas: The coastal region of Oregon, including cities like Portland and Astoria, typically receives moderate amounts of snowfall. These areas may see snowfall during the winter months, but it's often mixed with rain or sleet. Snowfall accumulations are generally lower, averaging a few inches to a foot or two during the season.
- Willamette Valley: The Willamette Valley, which encompasses cities like Salem and Eugene, experiences a similar snowfall pattern as the coastal areas. Snowfall is occasional and usually lighter, with accumulations ranging from a few inches to a few feet during the winter.
- Cascade Mountains: The Cascade Range in Western Oregon receives significantly higher snowfall compared to other parts of the state. Ski resorts such as Mount Hood Meadows, Timberline Lodge, and Mount Bachelor are located in the Cascades and benefit from substantial snowfall throughout the winter season. These areas can receive several feet of snow, with annual accumulations reaching as high as 400 inches (10 meters) or more.
2. Eastern Oregon:
- High Desert Region: Eastern Oregon, including areas such as Bend, Burns, and Ontario, experiences a more continental climate and receives less snowfall compared to Western Oregon. The high desert regions tend to have colder temperatures, but snowfall can be unpredictable and vary from year to year. Average annual snowfall in these areas ranges from a few inches to about a foot.
- Blue Mountains: The Blue Mountains in Eastern Oregon, particularly around the towns of Baker City, Enterprise, and Joseph, receive more significant snowfall. These areas can experience moderate to heavy snowfall during the winter, with accumulations ranging from several feet to as high as 200 inches (5 meters) in some years.
In summary, Oregon's snowfall varies considerably across different regions. The Cascade Mountains in Western Oregon and the Blue Mountains in Eastern Oregon receive the heaviest snowfall, while the coastal areas and the high desert regions experience relatively less snowfall.
