PORTLAND -- The first low snow levels of the season are set to arrive before the Thanksgiving holiday weekend comes to an end.
Motorists should realize conditions will be dry to start holiday travels, but turn stormy for the drive home. A strong cold front tracking to arrive this Saturday night could drop snow levels to near 1,000 feet Sunday and Monday.
Cascade travel will likely be impacted with heavy accumulating snow in the forecast. Motorists driving over the mountains should prepare for all-out winter conditions before the weekend comes to an end.
The low snow level may also produce snow and ice over the high Coast Range passes.
(Photo above shows Mt. Jefferson Tuesday afternoon. Santiam Pass, seen below, was all dry Tuesday.)
Here are the elevations for the most traveled highways in our local region
- Government Camp, US Highway 26: 4,026 feet
- Santiam Pass, Hwy 20: 4,817 feet
- Willamette Pass, Hwy 58: 5,128 feet
- Siskiyou Pass, I-5 south: 4,310 feet
- Snoqualmie Pass, I-90: 3,022 feet
Coast Range Passes:
- Highway 26: 1,600 feet
- Murphy Hill, Hwy 18: 760 feet
- Dudlee Hill, Hwy 20: 860 feet
Keep in mind, if current forecast temperatures for the Cascades are correct, Sunday highs in the 20s at Government Camp would likely lead to snow-packed roadways, with ODOT putting down rock and plowing as needed. Traction tires and or chains should be carried.
Please keep updated with the latest weather alerts and have a safe holiday weekend.
